Art. I.Monograph of New Zealand Noctuina.

[Read before the Philosophical Institute of Canterbury, 7th October, 1886.]

I have described the species of this group on the same method as that employed in my paper on the Geometrina,* and the remarks prefatory to that paper may be taken to apply generally to this also.

The species of Noctuina are commonly very dull coloured, and very similar in marking. It is, therefore, not surprising that those writers who classify by superficial appearance have found themselves in a frightful state of confusion; but the structural classification of the group is really not difficult. As an example of the sort of work produced, I will merely point out that fifteen described species of New Zealand Noctuina, all truly referable to the same genus, Mamestra, have been classed by these writers in eighteen different genera, under five distinct families. As the New Zealand fauna is very limited in character, it may be useful to remark that genera such as Hadena, Xylina, etc., to which several of these species have been referred, are really existing genera, quite distinct in structure, and have not been merged by me in Mamestra; I have simply corrected the erroneous reference.

The specimens described in this paper were mainly from the collection of Mr. R. W. Fereday, to whom I am greatly indebted for the loan of them. Mr. Fereday has devoted especial attention to the group, and his collection is a very valuable record of labour; but, as it was taken principally in a few limited localities, it is doubtless incomplete. I imagine that, as in the Geometrina, new species will come mainly from the alpine regions. During my last visit to the table-land of Mount

Arthur I tried the effect of sugaring, with much perseverance and a total absence of result; the only species I took were found by day, but I think an attracting lamp would have been effective. The failure of sugar is probably due to the very great abundance of flowers.

Seventeen genera are recorded, of which number six are represented only by single wide-ranging species, and are not to be regarded as belonging to the true indigenous fauna; five are endemic, and represented in all by only six species; and the remaining six are wide-ranging, and probably almost cosmopolitan genera. Sixty-three species are given, of which nine are found also in Australia, several of them ranging much further; the remainder are endemic. Forty-two—that is, two-thirds of the whole number, or nearly seven-ninths of the endemic species—belong to the two closely-allied genera Leucania and Mamestra, the distinction between which is very slight. Compare with this the predominance of the two closely allied genera, Larentia and Notoreas, among the Larentiadœ (Geometrina); the analogy is so close as to suggest a common origin in time for the New Zealand fauna of both groups. I have little hesitation in asserting, though I cannot yet adduce conclusive proof, that the Larentiadœ of New Zealand approach much more nearly to those of Chili than of any other country, and perhaps the Noctuina may be found to display a similar relation.

Noctuina.

Forewings with vein 1 simple, 5 rising nearer to 4 than to 6, 7 and 8 from a common stalk. Hindwings with 1c obsolete, 8 rising out of upper margin of cell near base, frenum developed.

Separated from the Geometrina by the position of vein 5 of the forewings. The following characters are also common to all the New Zealand genera of the group, and are therefore given here, to avoid needless repetition:—Face vertical or obtusely prominent; ocelli present; tongue well-developed; palpi (unless specially mentioned) moderate, obliquely ascending, second joint densely rough-scaled or hairy, terminal joint short, smooth, cylindrical; thorax very densely hairy; tarsi more or less strongly spinose, spurs well-developed; forewings with vein 6 almost from a point with 9, 7 and 8 out of 9, 10 connected with 9 by a bar (except in Erana); hindwings with veins 3 and 4 approximately from a point, 6 and 7 approximately from a point.

The markings are assumed to consist typically of first, second, and subterminal lines, a median shade or cloudy line between first and second, and orbicular, claviform, and reniform spots; the position of all these is practically identical in all

– 5 –

the New Zealand species. The first line runs from about ⅓ of costa to about ⅖ of inner margin, the second, rather curved on upper portion, from about ⅔ of costa to about ⅔ of inner margin; the orbicular and reniform successively between these above middle, the claviform immediately beyond first line below middle.

The two families represented in New Zealand differ essentially only in the structure of vein 5 of the hindwings:—

Noctuidœ. Hindwings with vein 5 imperfect, parallel to 4.

Plusiadœ. Hindwings with vein 5 well-developed, approximated to 4 towards base.

Appendix.

The following names represent unidentified descriptions; probably they are synonymous with some of the preceding. I do not quote the descriptions, which are of little value:—

64. Xylina spurcata, Walk., Noct., 631.

65. Orthosia infensa, Walk., Noct., 748.

66. Xylina provida, Walk., Noct., 1737; X. canescens, ib., Suppl. 757.

69. Xylina vexata, Walk., Suppl. 755.

70. Euplexia insignis, Walk., Suppl. 724.

Walker and Butler quote two other species, Agrotis munda and Heliothis peltigera, but there is no reason to doubt that these records are erroneous, and founded on a mistaken identification.

Art. II.On the “Honeydew” of Coccidæ, and the Fungus accompanying these Insects.

[Read before the Wellington Philosophical Society, 25th August, 1886.]

Plate I.

It has long been known that, in common with the Aphididœ, Psyllidœ, and other Rhynchota, the Coccidæ secrete a glutinous fluid, which has received the name of “honeydew.” In the other families mentioned, this fluid serves to attract and to feed various insects: thus, for example, Aphides are commonly visited by ants, which devour the honeydew, and even, it is said, go so far as to tickle the Aphides, in order to make them secrete additional fluid. Whether the secretion of Coccids may serve as food for other insects is not certain. I have never noticed anything tending to this idea: often, minute dipterous and hymenopterous insects may be seen amongst Coccids on leaves, but I incline to the belief that certainly the latter, and possibly the former, are seeking rather a place for depositing their eggs than a meal of honeydew. Hymenopterous insects are very often parasitic on Coccids: and out of a hundred pupæ of, say, Ctenochiton perforatus, as many as seventy-five may often be found with hymenopterous pupæ or larvæ inside them. Acarids of various kinds are also very numerous on leaves where Coccidæ are found; but, whilst it is quite possible that they may be attracted by the honeydew, this may not be the case, as Acarids are numerous and common on all plants, whether infested with Coccids or not. On the whole, I cannot affirm that the Coccid honeydew affords nutriment to any insects. I have never seen an ant amongst Coccids: but ants are not common in New Zealand, and this point is only negative, after all.

Still, the fact remains that Coccidæ exude, like other Rhynchota, a glutinous fluid. This is well known, but I think that nobody as yet has described either the mode or the organ of the secretion. An observation lately made enables me to fill this lacuna, and the points noted are not without interest in the study of the family. It happened that I was lately examining some specimens of the second, or pupa, stage of the female of Ctenochiton elœocarpi, mihi.* In one of these I noticed a sudden protrusion of an organ from between the

[Footnote] * “Trans. N.Z. Inst.,” vol. xvii., 1884, p. 26.

– 42 –

two dorsal abdominal lobes, and the excretion of a drop of honeydew.

Ctenochiton elœocarpi, like all Lecanids, exhibits at the abdominal extremity a deepish narrow cleft, on the dorsal side of which are two roundly-triangular protruding lobes. In a specimen of the second female stage it may be seen, under the microscope, that these lobes lie in a shallow groove formed by the sides of the cleft. At intervals, which may vary in length, the insect protrudes rapidly from beneath the lobes a cylindrical organ (figs. 1a, 1b,), composed of a basal, thickish tube, bearing at its extremity another, similar, but much thinner. The organ being pushed out to its full extent, a minute globule of transparent glutinous fluid appears at its extremity, rapidly expands, something like a soap-bubble, and then suddenly breaks and falls in spray on the leaf. The excreting organ is then rapidly withdrawn.

I do not entertain much doubt that the process just described is the same used by all the “honeydew”-secreting Coccids. Some of these, like Rhizococcus fossor, Planchonia epacridis, etc., produce much less than others; but even they, I think, excrete some. The observation which I have made as above throws a light upon an organ which I noted as occurring in the second female stage of Cœlostoma zœlandicum, in vol. xiv. of the “Transactions,” page 227, and in the adult female of the same insect in vol xii., p. 295. I then considered this organ as an oviduct, remarking, however, that I could not see its use in the pupal stage. I never saw it exserted, and was not aware that it ever was so; but it seems clear to me now that this is an organ similar to the one excreting honeydew in Ctenochiton elœocarpi, and it probably occurs in at least most of the other Coccids.

But observation of this organ is extremely difficult, if not in most cases impossible. The best and most careful work on the anatomy of Coccids is that of Professor Targioni-Tozzetti, “Studie sulle Coccineglie” (Milano, 1867); and there is no mention in it of any such organ. I have carefully, at various times, examined in every way many specimens of different genera, and, with the exception of Cœlostoma (an exceptionally gigantic species), I have not seen it.

There is no doubt of the quantity of glutinous matter secreted by Coccids; but, as observed above, the origin and mode of the excretion have not been noticed before. There does not appear to be any other organ, or any other portion, of the insect's body, producing this secretion; and it may well be that the absence of insects feeding on the honeydew may be due to the fact that the excreting organ, instead of being constantly protruded like the cornicles of the Aphididæ, is only now and then exserted and then withdrawn. In many genera,

– 43 –

such as Aspidiotus, Ctenochiton, Inglisia, Eriococcus; etc., the character of the shield or test, waxy or cottony or felted, would prevent the honeydew from exuding anywhere but at the abdominal extremity; there, however, there is almost always some kind of orifice or cleft permitting the extrusion of the excreting organ.

A point of considerable economic importance is connected with this honeydew of Coccids, namely, the growth upon it of various fungi; and I take this opportunity of drawing the attention of farmers and tree-growers to it, as I believe that a good deal of misconception exists in its regard. Everybody, doubtless, has observed how, in gardens or in greenhouses, in plantations or in forests, many plants have an unpleasantly blackened appearance; and it frequently happens that the true colours of the twigs and leaves are much, if not quite, obscured by the black coating on them (see figs. 2a and 2b). Now, it will generally be observed that this black coating is in most cases thicker and more unsightly on the lower than on the upper leaves and branches: sometimes, indeed, the uppermost leaves will be bright green, whilst the lowest look as if they were covered with soot. It will also be noticed that the black coating is abundant, not only in the damp recesses of the forest, but also in comparatively dry greenhouses, and just as much so in open-air gardens.

The primary cause of this is usually the presence of some homopterous insects, whether Aphididœ, Psyllidœ, Coccidœ or others. The “honeydew” excreted by them drops, or in the case of Coccids falls in spray, over the leaves beneath them: it very soon furnishes a glutinous and congenial soil for the spores of fungi. If one may judge from the quantity of black coating often found, the act of excretion above described must be repeated somewhat frequently, though so seldom observed.

As to the question, what is this black sooty coating: there is no doubt of its fungoid character, but I am not able to identify it precisely. There seem to be, in fact, several species in it. On the leaves, the fungus forms usually a flat, black, thinnish, closely woven covering; on the twigs and stem it has a looser texture, and generally forms a mass of small erect threads (see figs. 2a and 2b). These appearances are by no means confined to New Zealand, and most writers on Coccidæ devote some phrases in passing to the fungus. Signoret* calls it “Fumagine;” Comstock calls it “Fumago salicina:” in an early paper of mine (1878) I attributed it to “Antennaria.” In point of fact, a good many of the Hyphomycetes and Physomycetes may be found amongst this fungoid growth. I have attached to this

[Footnote] * “Essai sur les Cochenilles.”

[Footnote] † Report of the Entomologist, U.S. Department of Agric., 1880.

– 44 –

paper (figs. 2c, 2d, 2e) rough representations of three different forms observed.

The economic point, however, to which I draw attention is that, as a general rule (I might even put it more strongly), the appearance of this black fungus is an indication of the presence of homopterous insects; probably, in New Zealand, of Coccidæ, because they are the most numerous of the order in this country. Now, a great deal has been heard of late years of the damages by scale-insects, and all sorts of people have written or experimented about them. I find that, amongst the diseases of trees, this black fungus-growth has attracted attention: but the misconception to which I alluded just now is that it has been considered as a separate, or primary, disease, which I do not think it is.

In Mr. Kirk's “Report upon the Diseases of Lemon and other trees in New Zealand,” the common notion is embodied, and, under the head of “Lemon Smut, or Black Blight,” the writer even emphasizes it, by saying that the excreta of Icerya purchasi (a scale-insect) had no share in its production, and that it was of “purely vegetable origin.” In answering, in 1885, questions by a Select Committee of the General Assembly upon tree-diseases, I combatted this view, and ascribed the black “smut” to fungoid growths, the result of the presence of homopterous insects. I believe that Mr. Kirk has now come round to this view of the question, which is, undoubtedly, the right one.

It stands to reason, then, that if a farmer, or orchard-grower, or gardener, observing this black growth on his trees, imagines it to be the primary cause of disease, and sets to work to eradicate it without attending to the insect pests, he will be simply throwing his labour away. And there is this important fact to be remembered, that it is not with scale-insects as with other insects. Coccidæ are impervious to many things which might, in other cases, be efficacious. There is a common belief which, like most superstitions, it is excessively difficult to destroy, that sulphur is an useful ingredient in what are called “scaly-blight destroyers.” I should not be in the least surprised to find that many who hold this belief do so because they have found the black fungus disappear, or lessen, after its use, for sulphur is undoubtedly a remedy for fungoid blights—e.g., oidium, etc.; and probably they never thought of looking more closely into the matter. All experience goes to show that sulphur, unless applied in such strength as to burn up insects, fungus, tree and all, is not a remedy against Coccids. Comstock, Riley, Hubbard, and others agree in this: and although, in newspaper

[Footnote] ‡ Boudier (Assoc. Fran. pour l'avancement des Sc., 1884) includes the European fungi developed in the honeydew of Aphis in the genus Cladosporium (Quart. Journ. Roy. Micros. Soc., Aug. 1886, p. 597).

– 45 –

accounts, and in the replies of farmers to questions from officials or committees, we find sulphur a common ingredient in the thousand-and-one mixtures recommended, I doubt very much if anybody could give an intelligent reason for its employment.

No harm will therefore have been done, I think, if this paper should induce gardeners and fruit-growers to go direct to the true origin of disease in their trees and neglect the secondary one. That the fungus will grow independently of scale-insects is, of course, indisputable: but those who wisely consider it as, in the vast majority of cases, merely an accessory to their presence, and who set themselves to destroy the Coccidæ or Aphididæ on the plants, will find the black fungus also very quickly disappear.

Plate II.
Group Coccidinæ.

Icerya purchasi, mihi. Plate II., figs. 1–4 (male).

By the kindness of the Rev. Mr. Colenso, of Napier, I have received some specimens of the male of this species. No published description of the male Icerya is known to me, though the insect must be common in California. The following description is therefore here given:—

Male insect large; body red, with a shining, diamond-shaped, black patch on the dorsal surface of the thorax; legs and antennæ black; wings dark-brown, marked with numbers of parallel, wavy, oblique, narrow stripes; main nervure red, branching once; there are also two longitudinal whitish stripes in each wing. Antennæ long, slender, with ten joints, all nearly equal; the last joint is clavate; all except the first are constricted in the middle and with two dilations, at each of which there is a ring of very long hairs, giving to the antennæ

– 46 –

almost a plumose appearance. From these dilations and the median constriction the antenna appears to have nineteen joints, and it requires close examination to show that there are really only ten. Eyes very large and prominent, dark-brown, and divided into numerous semi-spherical facets; at the base of each eye is a prominent tubercle. Feet long, and very hairy; coxæ short and thick, tibiæ long and slender; claw thin. The digitules appear to be represented; by two minute bristles on the claw, as in Cœlostoma zœlandicum. Abdomen long and slender, with eight cylindrical segments, each segment bearing some hairs; the last segment ends in two conspicuous, thick, cylindrical processes which, when the insect is viewed sideways, are seen to turn upwards, and beneath them the conical, sharp-pointed sheath of the penis turns downwards (figs. 3, 4); penis large, reddish-coloured, with many recurved short hairs, and at the end a ring of short spines. Each terminal process of the abdomen bears three or four long strong setæ.

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

Length of the body somewhat variable; some of my specimens attain ⅛ inch; expanse of wings ¼ inch; length of antenna 1/9 inch.

This is a very handsome insect, clearly showing the characters of the group Monophlebidœ, and a little resembling the male of Cœlostoma; but specially fine in its variety of colours. The antennæ approach those of Leachia; the two abdominal terminal processes recall the six or eight tassels of Monophlebus. Mr. Colenso informs me that the insect flies strongly and swiftly, which is rather exceptional amongst Coccids, whose wings usually seem too weak for them.

Group LecanidinÆ.

Sub-section Lecano-CoccidÆ.*

Abdominal cleft and lobes present in all stages of female. Insects covering themselves with a secretion of cottony or felted matter, forming more or less complete sacs.

Genus, Eriochiton, gen. nov.

Secretion white, felted, formed of agglutinated threads issuing from prominent spiny spinnerets; inconspicuous or absent on adult female, more or less noticeable on female larvæ and pupæ; thick on male pupa. Abdominal cleft and lobes normal. Feet and antennæ present in all stages. Adult antennæ seven-jointed.

Differs from Lecanodiaspis, Targioni, in retaining the feet, and in the antennæ; from Philippia, Targioni, in not constructing its sac, or test, simply for gestation.

New Zealand Coccidæ

– 47 –

The fact that the tibia is shorter than the tarsus in the adult female, in both the species here given, is quite exceptional in the family. It occurs only, besides in these, in some species of Acantho-coccidœ; in all others, a tibia shorter than the tarsus is an indication that the specimen examined is not full-grown. I have hesitated to include this amongst the generic characters of Eriochiton until at least a third species has been found possessing it. Some persons are fond of creating genera and species from a single specimen or two. I do not agree with this.

Eriochiton spinosus.

(Ctenochiton spinosus, mihi.)

From closer examination of the female test of this species I find that it is not formed of waxy plates but of felted threads.* and I am therefore obliged to remove it from the genus Ctenochiton. It should be described as follows:—Test of female white, thin, formed of felted threads; inconspicuous in all stages and often absent from the adult, but distinguishable on the larva and on the second, or pupal, stage.

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

The male test (which I have only lately found) is white, thick, felted, oval, convex, averaging 1/16 inch in length.

To the description of the adult female already given in former papers, it must be added that the tibiæ are shorter than the tarsi, a very exceptional character.

The adult male (only lately found, and apparently very rare) is of the normal Lecanid form; colour generally dark brown. Eyes: two dorsal, two ventral; and two ocelli. Antennæ of ten joints; the second thicker than the rest, the third and fourth the longest, the eighth, ninth, and tenth moniliform; all the joints hairy, and on the five last joints are several hairs with clubbed extremities. Feet slender, hairy; digitules fine hairs. Abdominal spike somewhat strong and sharp; and on each side of its base is a tubercle bearing two long setæ, and each pair of setæ becomes enclosed in a long white cottony thread, the two threads forming conspicuous “tails,” as is common with many male Coccids.

Eriochiton hispidus, sp. nov. Plate II., figs. 5–8.

Test of female white, very thin, felted, formed of threads secreted by the numerous spiny spinnerets. At the edge

[Footnote] * The tests of all Lecanids may be said to be more or less “waxy;” and I am not certain that there is any chemical difference between them: but there must be some reason why, in certain species, the secretion forms plates of wax which are apparently homogenous, whilst in others the threads issuing from the spinneret tubes never entirely coalesce. I believe the distinction which I have made between “waxy,” “cottony,” and “felted,” and which is made also by other writers, is quite clear enough for generic purposes; though it may never be worth while for anybody to ascertain the chemical reasons for it.

– 48 –

each thread corresponds with one of the marginal spines, and forms a more or less conspicuous fringe, the segments of which are cylindrical tubes, not feather-shaped as in E. spinosus. Test often absent on the adult female, and always fragmentary: it is better observed on the second, or pupal stage, or on the larva.

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

Test of male white, thick, felted, oval, and convex, completely covering the pupa. Length about 1/16 inch. As the test exhibits a kind of segmented appearance, with transverse obscure grooves, it may at first sight be mistaken for a dactylopid insect.

Larva normal of the Lecanid group; flat, elliptical, active, exhibiting the abdominal cleft and lobes. Dorsal surface covered with numerous spiny spinnerets, from which issue the threads of the test and fringe.

Female of the second (pupal) stage more or less elliptical, slightly convex, reddish-brown in colour beneath the thin white felted secretion, which often presents an obscurely segmented appearance, due to the transverse rows of spiny spinnerets. Dorsum covered thickly with these spines, which are sub-cylindrical, with rounded tips, and spring from tubercular bases. On the ventral surface many small spiny hairs. Abdominal cleft normal, the lobes large. Mentum monomerous, the tip bearing several hairs. Antennæ of six somewhat hairy joints. Feet with rather large femora; digitules all fine hairs. Anogenital ring bearing several hairs.

Adult female elliptical, convex, reddish-brown in colour, hollow beneath; usually affecting the twigs of the plant in preference to the leaves. Apparently naked, but on close inspection found to retain at least portions of the thin felted secretion. Dorsum covered with great numbers of the spiny prominent sub-cylindrical spinnerets; ventral surface bearing many small spiny hairs. Antennæ of seven joints (fig. 6). Feet with large coxæ and femora; tibia a good deal shorter than the tarsus; lower digitules only fine hairs.

Adult male reddish-brown in colour; form normal of Lecanidæ. Two dorsal eyes, two ventral eyes, two ocelli. Antennæ ten-jointed, the last three moniliform; second, third, and fourth the longest. On the five last joints are several hairs with clubbed extremities. Feet slender, hairy. Abdominal spike rather strong and sharp; and on each side of its base is a broad tubercle bearing two long setæ, which become joined in long cottony “tails.”

Habitat.—On Olearia haastii, found as yet (in great numbers) only on a plant cultivated in the Botanical Gardens, Wellington. It is rapidly killing the shrub. O. haastii is, I believe, an alpine plant.

This species is distinguished from E. spinosus by the great number of spiny spinnerets on the dorsal surface of the female, and by the cylindrical tubes of the fringe. Its colour is also rather redder and lighter; but that is not a valuable character. I cannot find any clearly distinguishing marks in the males of the two species.

Art. IV.On the Freshwater Infusoria of the Wellington District.

[Read before the Wellington Philosophical Society, 30th June, 1886.]

Plates III., IV., V.

The following is the result of some investigations by the Microscopical Section of the Wellington Philosophical Society, Messrs. A. Brandon, jun., W. F. Barraud, C. P. Powles, T. W. Kirk, and the writer. These investigations have only been undertaken in the intervals of leisure afforded to men engaged in the ordinary work of life: the result, therefore, can be taken simply as complete as far as it goes; that is, merely a systematic list of the freshwater infusorian life here. The preparation of similar lists appears to be desirable in any country, and especially so in New Zealand, where the fauna and flora offer still so large a field for the inquiries of students of Nature.

The want of full opportunities and ample time, hinted at above, and the difficulty of arranging and working with apparatus constantly requiring attention, have prevented the members of the section from properly investigating the development of the animalcules herein presented as new to science. But, as these have not necessitated the establishment of any new genera, and as the processes of reproduction have been so fully studied and described in other countries, the defect in the present case is not of great importance. The phenomena of reproduction by fission have, of course, been frequently noticed, but time and opportunity have not been available for their continuous observation.

– 50 –

Two points require slight mention here. First, it is to be noted that in many instances, where animalcules have been referred in this paper to described species, there have been observed minute variations, not considered sufficiently important to induce the erection of a new species, yet often tending to make identification a matter of some difficulty. Instances of this may be mentioned in the genera Stentor, Euglena, and others, and especially, perhaps, in the Heterotrichous Order. It has been considered desirable to avoid as much as possible the multiplication of species. Secondly, it is noticeable that in some instances—e.g., Aspidisca turrita, Licnophora setifera—animalcules inhabit freshwater here which are only reported from sea-water in Europe or elsewhere.

Finally, it is to be observed that examination has only been made into strictly freshwater animalcules, excluding marine or “infusion” types. The present paper, being only the beginning of what may easily be a long task, has been purposely complicated as little as possible.

The occurrence of this curious monad with Rhipidodendron, here, as at Dartmoor in England, seems to suggest possible connection between the two. Neither of the two appears to have been recorded from any other locality. The character of the zoocytium, or common gelatinous granuliferous mass enclosing the animalcules, seems scarcely to vary in the two genera; and the main difference would appear to lie in the fact that the animalcules of Rhipidodendron inhabit separately the tubes of a branching zoocytium, those of Spongomonas living together in the common mass.

A variation of this infusorian, which might perhaps be a new species, was observed on one occasion, but not sufficiently examined. The cuirass was nearly twice as long as broad, almost ovate, and the posterior extremity exhibited a narrow, not very deep, slit.

Class II. Ciliata.
Order. Holotricha.

Genus Paramœcium.

Paramœcium aurelia, Müller. Wellington, Wainui, Hutt Valley.

Paramœcium bursaria, Ehrenberg. Wellington, Hutt Valley.

Genus Prorodon.

Prorodon sulcatus, sp. nov. Plate III., fig. 4; a, b.

Animalcules free-swimming; motion gliding, sometimes rotatory, not rapid. Body persistent in shape, cylindrical, ovate, slightly narrowed anteriorly, longitudinally furrowed by numerous, somewhat deep, striæ. Oral aperture terminal, narrow; pharynx narrow, cylindrical, somewhat deep, armed with numerous rod-like teeth which are very inconspicuous. Nucleus band-like, curved, sub-central. Contractile vesicle single, at the posterior extremity.

Length, 1/300 inch = 83 μ; greatest width, about 1/400 inch = 62 μ.

Wellington, W. M. Maskell.

No mention appears to be made in descriptions of recorded species of the longitudinal furrows mentioned above. These show as conspicuous striæ in viewing the animalcule on the side; but in end view they become apparent as furrows. Other differences from P. niveus, P. teres, etc., are size, the narrowness of the pharynx, and the inconspicuous rods. After treatment with iodine, a kind of protrusion of the oral aperture is sometimes visible.

Genus Trachelophyllum.

Trachelophyllum apiculatum, Perty. Mungaroa.

Genus Coleps.

Coleps hirtus, Ehrenberg. Wellington, Wainui.

Genus Tillina.

Tillina enormis, sp. nov. Plate III., fig. 5.

Animalcule free-swimming; motion rapid, gliding, some-times spiral. Persistent in shape, elongated, scarcely showing any reniform outline; length about three times the greatest width. Oral aperture ventral, slightly in advance of the median line; simple, fringed with cilia longer than those of the body;

– 54 –

followed by a distinct curved pharynx. Pharynx simply ciliated throughout. Nucleus oval, conspicuous, sub-central. Contractile vesicles two, near the extremities, often exhibiting stellate appearance, as in the figure. Body finely ciliated throughout, also sparsely striated longitudinally.

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

Length 1/30 inch = 833 μ.

Wellington, W. M. Maskell.

A large and distinct species, placed here in the genus Tillina on account of the characters of the oral aperture and pharynx. The longer cilia of the former remove it from Paramœcium, and the absence of a vibratile membrane in the latter distinguishes it from Plagiopyla or Colpidium. Anophrys has no cilia in the pharynx. Kent assigns to the genus only one contractile vesicle, and in his species, as well as in those reported from America by Professor Stokes,* the outlines are distinctly reniform; but these points do not seem sufficient to demand a new genus for the New Zealand animalcule. The shape and dimensions given above were very constant in a large number of specimens observed.

Tillina inequalis, sp. nov. Plate IV., fig. 6.

Animalcules free-swimming; motion rapid, gliding; persistent in shape, outline sub-reniform, the posterior portion larger than the anterior. Oral aperture ventral, a little in advance of the median line, situated in the shallow and not extensive depression of the body. Oral cilia longer than those of the body. Pharynx curved, not conspicuous, simply ciliated: no vibratile membrane. Nucleus inconspicuous, circular, posteriorly sub-central. Contractile vesicle single, sub-central, near the extremity of the pharynx. The food particles usually collected in a number of circular masses. Body finely ciliated throughout.

Length, 1/240 inch = 104 μ; greatest width, 1/400 inch = 62 μ.

Wellington, W. M. Maskell.

This animalcule seems most nearly allied to T. inflata, Stokes, but differs in the inequality of the anterior and posterior portions, and in the shallowness of the depression between them. The form and dimensions given are quite constant. Tillina campyla, Stokes, is much narrower and smaller generally.

Genus Trachelocerca.

Trachelocerca filiformis, sp. nov. Plate V., fig. 15; a, b, c.

Animalcule highly elastic and variable; body fusiform, somewhat pointed posteriorly, produced when extended into

– 55 –

an exceedingly long filiform neck, often reaching six or seven times the length of the body, and terminating in an obtuse sub-conical region rather wider than the neck, with a circle of longer cilia beneath it. Contractile vesicle single, posterior: endoplast elliptical, sub-lateral. The whole body and neck are marked with a network of striæ.

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

Length when fully extended reaching perhaps 1/70 inch = 357 μ, but the twistings and curlings of the thread-like neck are so rapid that measurement is very difficult.

Wellington, W. F. Barraud.

Closely allied to T. olor, Müller, but differing in the position of the single contractile vesicle and the character of the nucleus.

Genus Amphileptus.

Amphileptus anser, Ehrenberg. Wellington.

Genus Colpidium.

Colpidium cucullus, Schrank. Wellington.

Genus Plagiopyla.

Plagiopyla varians, sp. nov. Plate IV., fig 7; a, b.

Animalcules free-swimming; motion rapid, gliding; persistent in shape, sub-reniform. Oral fossa ventral, a little in advance of the median line, sometimes shallow, broad, and at right angles to the axis of the body, sometimes tubular, conical and oblique; containing a narrow vibratile membrane which does not quite reach to the aperture. Nucleus posteriorly located, conspicuous, circular. Contractile vesicles 2, placed between the oral fossa and the posterior extremity.

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

Length, 1/200 inch = 125 μ.

Wellington, W. M. Maskell.

Resembling P. nasuta, Stein, but differs in the position of the nucleus, the two contractile vesicles, and the variation of the oral fossa. The animalcules observed presented this variable arrangement in a large number of specimens, and were at first thought to be distinct; but on further consideration they seemed to be really the same.

Genus Pleuronema.

Pleuronema coronata, Kent. Wainui.

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

This animalcule appears to be identical with Kent's infusorian in everything except size. The European species is stated to have a length of only 1/290 inch = 86 μ, whilst the Wainui specimens reached 1/200 inch = 125 μ. It is not P. chrysalis, as it possesses long, fine, rigid setæ in addition to the cilia.

– 56 –

Pleuronema cyclidium, sp. nov. Plate V., fig. 16.

Animalcules sub-reniform, with very shallow groove, about twice as long as broad, having a number of long fine hair-like setæ over the whole body; setæ of equal length throughout. Extensile membrane of the oral region narrow, and rather deep when extended. Contractile vesicle single, at one extremity; nucleus sub-central, elliptical. A number of granular masses often visible in the parenchyma.

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

Length, 1/1330 inch = 19 μ.

Wellington, A. Brandon.

Differs from P. chrysalis and P. coronata in its extremely small size, which was constant in many hundreds of specimens observed, and which would make it approach nearer to Cyclidium or Uronema, except for the absence of the long caudal setæ characterizing those genera.

Genus Cyclidium.

Cyclidium glaucoma, Ehrenberg. Wellington.

Genus Uronema.

Uronema marinum, Dujard. Wainui.

Order Heterotricha.

Genus Metopus.

Metopus sigmoides, Müller. Wellington.

Genus Spirostomum.

Spirostomum ambiguum, Ehrenberg. Wainui, Hutt Valley.

Genus Stentor.

Stentor gracilis, sp. nov. Plate V., Fig. 13; a, b.

Body of moderate size, highly extensile, white or light-brown: when fully extended very slender for almost all its length and suddenly widening to the peristome, giving something of the appearance of a broad-headed nail. Peristome at full extension nearly half as wide as the length of the body. Sides of the extended stem nearly parallel, average width below the peristome region about one-fifteenth of the total length. Parenchyma containing often several dark-coloured granular masses. Contractile vesicle spherical, situated below the peristome. Endoplast band-like. Peristome border narrow, slightly emarginate in its whole extent, with a very deep cleft on one side extending for some distance down the stem; the cleft bears the usual peristomal cilia. Body when free-swimming elongate, racket-shaped, exhibiting the cleft of the peristome almost closed, as a narrow longitudinal slit.

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

Length of the extended animalcule rather more than 1/30 inch = 833 μ.

Wellington, Hutt Valley, W. F. Barraud.

– 57 –

The slenderness of the extended stem, the sudden widening of the peristome, the deep lateral cleft and the white colour, separate this from all described species. The dimensions and form given were constant in several specimens observed.

Stentor striatus, sp. nov. Plate V., fig. 14; a, b.

Body very large, dark-green with almost a blue tinge, highly elastic. When fully extended it has something of the shape of an old-fashioned deep champagne-glass, being narrow and very long, widening gradually from the point of attachment to the peristome, which is not recurved and widened, being scarcely wider than the portion of the body beneath it. The peristome edge is irregular, rising at one spot to a sharp point, and in another depressed in a not very deep groove, beneath which is a sub-cylindrical transverse region of very dark - green colour, reaching nearly to the median line: this appears, when the animalcule is free-swimming, as a conspicuous helical coil. Parenchyma containing several large granular masses, often coloured brown. Contractile vesicle spherical, below the peristome. Endoplast long, moniliform. The whole body is marked with broad, conspicuous striæ, which are most perceptible in the contracted state, and which give a crenulated appearance to the edge when the animalcule rolls over and is seen from one end.

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

Length of the fully extended body 1/11 inch = 2260 μ.

Wellington, Ohariu, W. F. Barraud.

The very large size, dark-green colour, conspicuous striæ, and scarcely expanded peristome of this species are sufficiently characteristic. Dimensions and form constant in many specimens.

Order. Peritricha.

Genus Halteria.

Halteria grandinella, Müller. Wellington, Wainui, Hutt Valley, Karori.

Genus Strombidium.

Strombidium claparedii, Kent. Wellington.

Genus Gyrocoris.

Genus Urocentrum.

Urocentrum turbo, Müller. Wainui, Hutt Valley.

Genus Licnophora.

Licnophora setifera, sp. nov. Plate IV., fig. 8; a, b, c.

Animalcules free-swimming, sometimes attached; motion very rapid, jerking or twisting. Body very irregularly shaped; the foot-like region more or less oval beneath, tumid, and bearing instead of cilia a few, about 20, somewhat strong setæ, of which

– 58 –

the greater number are collected in two groups at the extremities of the foot. Neck-like region long, slender, compressed, elastic, bearing numbers of short fine cilia. Anterior portion or head variable in form from triangular to oval; peristomecilia long and conspicuous, surrounding the large oral aperture. Nucleus oval, inconspicuous, situated in the foot-region. Contractile vesicle not observed.

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

Length variable, from 1/900 inch = 28 μ when contracted, to 1/350 inch = 71 μ when extended.

Wellington, W. M. Maskell.

This is the first species of the genus as yet reported in fresh water. It is somewhat larger than either of the two European marine animalcules, and differs also in the presence of strong setæ, instead of cilia, on the foot-region.

Genus Vorticella.

Vorticella annularis, Müller. Karori.

Vorticella longifilum, Kent. Wellington.

Vorticella campanula, Ehrenberg. Wellington.

Vorticella elongata, De From. Wellington.

Vorticella patellina, Müller. Wellington, Wainui.

Vorticella nebulifera, Ehrenberg. Wellington.

Vorticella aperta, De From. Wellington.

All the above species are reported by Mr. T. W. Kirk, in “Trans. N.Z. Inst.,” vol. xviii., 1885, p. 215.

Genus Zoothamnium.

Zoothamnium affine, Stein; var. granulatum, var. nov.

Resembles almost entirely the European infusorian, but has a longer pedicle and a rough granular surface. It was also not observed on aquatic animals, but on plants.

Wellington, A. Brandon.

Genus Epistylis.

Epistylis leucoa, Ehrenberg. Wellington.

Ehrenberg's species, according to Kent, p. 705, has not been observed for many years. The present infusorian agrees with it entirely, with the exception that the surface is granular and the colonies larger, containing 20 to 35 individuals.

Genus Opercularia.

Opercularia parallela, sp. nov. Plate IV., fig. 9.

Body slender, about three times as long as broad, sides parallel for about two-thirds the length from the margin, then

– 59 –

tapering rapidly to the pedicle. Peristome border not, or only slightly, thickened. Ciliary disc moderately elevated, cilia in a single row. Endoplast band-like, curved, nearly transverse. Cuticular surface granular. Contractile vesicle single, near anterior margin. Pedicle annulated, branched.

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

Length of body 1/350 inch = 71 μ.

Wellington, T. W. Kirk.

Closely allied to O. cylindrata, Wrzes., but more cylindrical and rough, without striæ.

Genus Platycola.

Platycola longicollis, Kent. Wellington.

Gastrostyla Steinii, Engelmann. Wainui.

Genus Histrio.

Histrio acuminatus, sp. nov. Plate IV., fig. 10.

Animalcules elongate-elliptical, with nearly parallel sides, somewhat pointed at the posterior extremity; border evenly ciliated. Peristome-field large, with long cilia and conspicuous reflected border, ciliated on left side. Three large uncinate frontal styles and a few smaller ventral setæ. Five simple anal styles, which project for about two-thirds of their length beyond the posterior extremity. Contractile vesicle single, situated just below the peristome-field. Endoplast elongated, conspicuous.

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

Length about 1/180 inch = 139 μ.

Wellington, Wainui, A. Brandon.

This animalcule resembles H. similis, Quennerstedt, but differs in the acuminate posterior extremity, and in the freshwater habitat.

Genus Stylonichia.

Stylonichia mytilus, Ehrenberg. Wellington, Wainui, Hutt Valley.

Genus Aspidisca.

Aspidisca turrita, Claparède. Wellington.

The European species only inhabits salt-water. There appear to be no differences between it and our New Zealand form, and the only point to be noted is the freshwater habitat.

An animalcule observed, having a very short and blunt dorsal spine, even in some instances without spine, is taken to be only a variety of this species.

Genus Glaucoma.

Glaucoma scintillans, Ehrenberg. Hutt Valley.

Genus Euplotes.

Euplotes patella, Ehrenberg. Wellington, Wainui, Hutt Valley, Mungaroa, Karori.

Class III. Tentaculifera.
Order. Tentaculifera-Suctoria.

Genus Sphærophrya.

Sphœrophrya magna, Maupas. Wellington.

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

This animalcule seems to agree entirely with Maupas' species (which is reported only from Algeria), with the exception of its size, which reaches 1/450 inch = 55 μ as against 1/600 inch = 41 μ in the African infusorian. All other characters being similar, it is not thought desirable to consider it as even a variety.

Genus Acineta.

Acineta elegans, sp. nov. Plate IV., fig. 11.

Lorica vase-shaped, with distinctly reversed margin, which is chiefly apparent at each side. Lorica widening somewhat below the edge, and rapidly compressed beneath, though not at once closing, but produced downwards to a point whence there is a short pedicle. Length from the point to the orifice about twice the width of the expanded margin. Animalcule nearly spherical, only occupying the upper half of the cup; tentacles forming two antero-lateral groups with about fourteen in each group; tentacles distinctly capitate, rather longer than the diameter of the animalcule. Contractile vesicle spherical, eccentric. Endoplast indistinct. Parenchyma granular.

– 61 –

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

Length of lorica, exclusive of pedicle, 1/300 inch = 83 μ; width at margin 1/600 inch = 41 μ; length of pedicle, 1/2000 inch = 12 μ usually, but reaching sometimes 1/1500 inch = 16 μ.

Wellington, C. P. Powles.

The animalcule of this species very nearly resembles that of A. grandis, Kent; but the form of the lorica separates it from all described species. A. poculum, Hartwig, a saltwater infusorian somewhat resembling it, has apparently a long pedicle.

Acineta simplex, sp. nov. Plate V., fig. 12.

Lorica wine-glass shaped, anterior edge not narrowed, lip not reversed, posterior extremity rounded, sides nearly parallel; pedicle moderately stout, about twice as long as the lorica. Animalcule occupying the anterior half of the lorica, subspherical. Tentacles capitate, arranged in two groups of about ten in each. Contractile vesicle situated on one side near the anterior margin.

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

Length of lorica, 1/500 inch = 50 μ; width of edge, 1/600 inch = 41 μ.

Wellington, T. W. Kirk.

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

Amongst the division of Acinetœ having the tentacles in two groups, the nearest to this seems to be A. grandis, Kent; but the sizes differ greatly, the European species having a length of 1/100 to 1/75 inch = 250 to 333 μ; also its lorica tapers much more rapidly to the base, which is obtusely pointed.

Art. V.On New Zealand Glow-worms.

[Read before the Wellington Philosophical Society, 4th August, 1886.]

Plate VIa.

The following article by Mr. Meyrick appeared in the “Entomologists' Monthly Magazine,” for April, 1886:—

A Luminous Insect Larva in N.Z.—Whilst collecting recently after dark beside a densely shaded creek near Auckland, New Zealand, I observed the precipitous earthy banks of the creek illuminated with great numbers of a larva, which has, I believe, never been reared. It resembles in general appearance an Annelid, being about an inch and a half in length, very slender, slimy, and without apparent organs; but under a microscope (as Prof. Hutton has shown me) the head appears that of a predaceous coleopterous larva—e.g., one of the Staphylinidœ. The light consists of a small light-greenish white erect flame, rising from the back of the neck. The larva burrows in the earth, exposing the head and anterior portions from the burrow, but having in front of them a sort of irregular slimy network. They occur in great numbers; I have counted fifty in a square foot of surface. The same or a similar species has been noticed in caves and mines elsewhere in New Zealand. It is impossible for a wandering entomologist to attack a larva of these habits. I should therefore be interested if any reader can give me a clue to its systematic identification. I suppose that it is carnivorous, feeding on minute insects, and I conjecture that it uses its lamp (as I do mine) to attract them, or perhaps to see to eat them.—E. Meyrick, Wellington, N.Z.—24th January, 1886.”

“[There is distinct necessity for further information (with examples in fluid) respecting the animal noticed above. The larvæ of Staphylinidœ are ordinarily so like the perfect insect in form (allowing for absence of elytra, etc.) that we venture to doubt the connection of the animal with that family.—Editors, ‘Ent. Mon. Magazine.’]”

It is extremely unfortunate that such an erroneous statement as the above, concerning one of our most interesting insects, should be the first to reach the ears of the London entomologists; and as it is the opinions of those gentlemen that will most influence us out here, I have instituted a number of observations on the insect, a summary of which I have sent in answer to the Editors' note, and propose to relate them to-night

– 63 –

in a somewhat more extended form. But in order that my remarks may be better understood, I will commence by stating that the Staphylinidœ are one of the most well-marked families of the Coleoptera, being none other than the famous Cocktail or Rove Beetles; their larvæ are furnished with six strong thoracic legs, a large head, and powerful mandibles, thus differing, as will be seen, in the widest possible manner from the insect under review.

Everyone who has walked in the bush at night, or, indeed, along any road at the bottom of a steep gully, cannot fail to have noticed the little points of light, mentioned as occurring in such vast numbers by Mr. Meyrick. I have not yet, however, seen 50 to the square foot of surface, although perhaps others may have been more fortunate; but, in my case, I should regard 20 of these little stars visible from one standpoint as indicating an exceptionally wealthy region.

When carefully examined with a bull's-eye lantern and pocket lens, this light is found to proceed from a large glutinous knob, situated at the posterior extremity of the larva, a fact I have verified by repeated investigations: but the insect's curious habit of occasionally travelling backwards has doubtless led to this mistake. It inhabits irregular cavities in the bank, where it hangs suspended in a glutinous web, which also appears to envelope the body, large quantities of sticky mucus being periodically shot out of the mouth of the larva, and formed into threads as required; but I have never seen anything like a net extended in front of the insect, neither have I found flies or gnats detained in the webs, although I have examined a large number. At the back of this irregular chamber the larva constructs a small hole, into which it retreats with great rapidity when alarmed.

With regard to its food, I am unable to speak, with absolute certainty on this point at present, but have little doubt that it consists of decaying vegetable matter. One individual I kept alive for eight weeks was enclosed in a small jar of mud, taken from his native bank, and placed in a caterpillar cage, where no flies or other small insects could possibly be obtained; as, however, there were some small earthworms in the mud, it might have subsisted on these, although I examined the insect nearly every night and morning and never saw it eat anything.

The light is not shown by any means regularly. On several occasions I have observed no light all the evening, and then a brilliant display at 3 or 4 o'clock in the morning, but have not noticed any peculiar meteorological conditions to affect this. As to its use, I do not think that Mr. Meyrick's explanation can be entertained, as I am sure everyone who has attracted insects at night will know how utterly inadequate such a minute point of light would be to draw them from the shortest distance. If

– 64 –

the larva requires a lamp to see to eat by, nearly all the New Zealand insects should have lights, as they are chiefly nocturnal. When, however, we reflect that the construction of the bee's comb is always carried on in utter darkness, the light would seem unnecessary for this purpose. If I might be allowed to suggest a use, I think it may often assist the larvæ in escaping from enemies, as when disturbed they nearly always gleam very brilliantly for a few seconds, suddenly shutting off the light and retreating into the earth. Of the pupa state I am as yet quite ignorant, as the only larva. I succeeded in rearing was left undisturbed during that condition, in order to insure the appearance of the imago. This turns out to be a small gnat, apparently one of the Tipulidœ, and not differing materially from many of those little long-legged Dipterons so often noticed on window-panes and in similar situations. The specimen, which is the only one I have as yet found, is now on its way Home for identificacation by a systematic, dipterist, and will in all probability be found undescribed.

Note.—Since the above was written, I have been informed by Baron Osten-Sacken, to whom I sent the perfect insect for identification, that it is Trimicra pillipes, the larva of which is well-known and different from the glow-worm. He still agrees, however, that the glow-worm is the larval condition of a gnat (Mycetophilidœ), and certainly not of a Coleopterous insect.—G. V. H.

Art. VI.Note on a curious Double Worm.

[Read before the Wellington Philosophical Society, 19th January, 1886.]

Plate VIB.

Some time ago, Mr. W. Marshall informed my father that there were some curious double worms in the Rangitikei, and promised to send him one. This promise he fulfilled a few weeks ago, the specimen now on the table being the one sent. It was placed in my hands for determination. I am not aware of any record of an Annelid of similar appearance. The anterior portion is about 1 inch in length and ¼th of an inch in diameter, and presents nothing peculiar so far; but from the posterior end of this

Picture icon

To illustrate Papers by T. W. Kirk.

– 65 –

thick part, which terminates abruptly, spring two limbs, each 2½ inches in length, and of an average diameter of ⅛th inch. These appendages make the animal look most grotesque. At first sight, these limbs look as though two worms of smaller circumference were grafted on to an abnormally short and thick individual. At times they trail behind like two tails, or are gathered up, sometimes together, sometimes one is moved first, the body pushed slightly forward with that, then the other is used, and so on alternately. The anal aperture is situate immediately at the posterior end of the thick portion, and between these two limbs or tails. There is no aperture in the end of either limb, though there is a spot which at first sight gives the impression that an opening is present.

I have not yet examined it very critically, lest it should sustain damage and die before I was able to exhibit it to this meeting.

It is a species of Acanthodrilis; but the question arises: Is it only an abnormal form, or are they tolerably common? Probably they are far from rare, as Mr. Marshall, in forwarding it, says: “I send you one of those two-tailed bush-worms I spoke to you about;” thus implying that he had seen others. He has been asked to endeavour to procure more specimens, and to send any information in his possession regarding their habits, abundance, etc. Till this information is received I prefer to suspend further decision as to its specific value.

This note was written for a meeting called in October, and which lapsed for want of a quorum. The worm has since died; but, as no other specimens have yet been received, I hesitate to dissect this one, and until that is done I feel that the examination is necessarily incomplete.

Art. VII.On Ixodes maskellii, a Parasite of the Albatross (Diomedea exulans).

[Read before the Wellington Philosophical Society, 19th January, 1886.]

I had intended in this short paper to include a number of species of parasitic insects lately obtained from young specimens of the Pencilled Albatross; but as I have been unable yet to identify several specimens, in consequence of th+++

– 66 –

difficulty experienced in obtaining works of reference, they will be retained for a future occasion, and your attention directed to a very large tick, two specimens of which were found with their claws so firmly imbedded in the neck of the bird as to render it impossible to remove them without the loss of some of their legs.

The genus to which this belongs is a very interesting one, for Mr. Murray tells us that their habits are at first herbivorous, that from the vegetation they find their way to the creatures on which they fix, and that when mature they avail themselves of every opportunity of fixing upon vertebrate animals, whose blood they suck instead of sap. It is very remarkable that these creatures should be at one time phytophagous and at another carnivorous. And it would seem that the usual special adaptation of structure to kind of food is absent; but Mr. Murray says that the anomaly is only apparent, and goes on to say that “carnivorous mammals are provided with different apparatus for obtaining their food from that of vegetable feeders; not on account of the different chemical constituents of their food, but on account of the different form in which it is presented to them for consumption and assimilation. If, for example, the food of both were presented to them in a liquid state, in the one case blood, and in the other juice of plants, we may be sure that the carnivorous canines in one case, and the vegetarian molars in the other, would be alike dispensed with, and both would be furnished with a sucking-up or pumping apparatus, which might be identical, if no speciality in the mode in which the liquid presented itself called for a difference. There might be a difference in the structure of their viscera, adapted to the character of the liquid food, but there is no reason why the external and oral structure should not be the same in both. This is what we find in all suctorial insects, bugs, gnats, Acari, etc. All are provided with a sucking apparatus constructed on a similar plan, which some use upon animals and others upon plants.” I read recently that some insects—for instance, the London house-bug—feed indiscriminately upon the juice of plants, and the blood of animals. The impossibility of the immense numbers of mosquitos that we meet with in the forests ever obtaining food if restricted to the blood of mammals has probably struck most of you. Is it not likely that they also are capable of living on a vegetarian diet, when no nice juicy specimen of humanity is forthcoming.

The insect to be noticed—viz., Ixodes maskellii (which I have ventured to name after Mr. Maskell, who described the only other species yet recorded from New Zealand)—is probably one of the largest of the genus, being, when alive, just under half an inch in length, excluding the rostrum; it is

– 67 –

elliptical, but with a pronounced lateral compression on the anterior third of the body, then gradually expanding again, the hinder third being slightly wider than the anterior. On the dorsal aspect two crescent-shaped shallow grooves rise from the posterior angles of the shield, and extend backwards for about one-third the length of the body, terminating in deep pits immediately opposite the lateral constrictions; from these pits two deep crescent-shaped grooves extend backwards, ceasing abruptly a short distance from the posterior margin. A straight medial depression, not so pronounced as the crescents, runs between them from the posterior margin for rather more than a third the length of the body. The pits are connected by a transverse line.

On the under-side, a deep and wide central groove starts at the posterior margin and runs for about one-fourth the length of the animal. Two equally deep and wide grooves commence in a line with the insertion of the third pair of legs, and run backwards, gradually widening till they reach the centre of the mesial groove, when they turn in rapidly, giving the inclosed space (from the third pair of legs to the posterior margin), much the outline of a Florence flask. The rostrum, in addition to the spines possessed by all the members of the genus, appears to be armed on its under side with five lines of hard-pointed tubercles.

The body of the animal when alive is of a delicate Frenchgrey colour; the shield on the head pale-brown; legs red, with white at the joints; rostrum same colour as the body.

It is generally supposed that a separate species of tick is appropriated to a particular species of animal. Although this appears to be usually the case it is not always so, as proved by the fact that in England the common species I. erinaces is found on rough herbage, in forests; and on dogs, cattle, foxes, and hedgehogs. A short time since I found on a large gull a tick exactly similar to the one from the Crested Penguin described about two years ago by Mr. Maskell.

Art. VIII.On the Occurrence of the English Scaly Lizard (Zootoca vivipara) in New Zealand.

[Read before the Wellington Philosophical Society, 30th June, 1886.]

In August of 1883 I had the pleasure of bringing under the notice of the Society two English butterflies—viz., the Red Admiral, or Alderman, and the Small Tortoiseshell, both of which were captured in the Wellington Botanic Gardens—and drew attention to the fact that the importation of plants and

– 68 –

seeds from various countries had become so extensive that it was almost certain much foreign animal life, some useful and some destructive, would be brought into the colony. It was also pointed out that, in order that the noxious forms might be more speedily detected, and to prevent confusion in future publications, it was advisable that the occurrence of unknown or uncommon species in a district should be promptly recorded.

The importation which I have now to notice is much higher in the scale than those already mentioned. It is the English Scaly Lizard (probably familiar to many persons present who in their young days rambled about the English country districts). As its food consists exclusively of insects, it is not likely to prove an unwelcome visitor.

Several specimens were captured about a year ago, on the Tinakori Hills, and one on the road, as it was crossing from the Botanic Gardens towards the shelter of the opposite bank. Being certain that it was quite distinct from any described New Zealand species, I took it to be a new form, and it was not until recently, when working up the specimens, that I became convinced it was a true British species.

As I have only found it in the localities mentioned, I conclude some specimens must have been brought to the Botanic Gardens in cases of plants. The following is the technical description:—

Zootoca.

Nostril on one side of the nose, in the lower hinder angle of the nasal shield, with one small posterior nasal. Lower eyelid opaque, scaly. Throat with a narrow cross-fold under the ears. Abdominal shields square. Temple scales small, with a larger central one. Pre-anal shield single, surrounded by smaller ones.

Z. vivipara.

(Gray, Cat. Liz. Brit. Mus., p. 27.)

Ventral shields, 8-rowed; the temple covered with manysided shields, with a larger central shield; olive, back with a white-edged blackish streak on each side, and a central black streak; belly orange, black spotted.

According to Wood, many of the habits of this pretty little creature resemble those of our common brown lizard, or Mokomoko, so abundant on the hills and beaches around Wellington.

In England, it is found plentifully upon the banks and commons; it is extremely lively, and progresses by means of a series of sharp twists and springs. It captures flies and other insects with great dexterity. So quick are its movements, and so sharp its sight, that capture is far from easy. The colour is extremely variable, but generally the upper parts are olive-brown, with a dark brown line often interrupted along the middle of the back,

– 69 –

and a broader band along each side, with black spots and blotches interspersed; the under-parts are orange, spotted with black in the male, and olive-grey in the female. The length is about 6 inches.

It is one of the reptiles that produce living young, the eggs being hatched just before the young lizards are born. The usual plan adopted by reptiles is to lay the eggs in some spot where the sun's rays are able to warm them. But the Scaly Lizard is in the habit of lying on a sunny bank before the young ones are born, apparently for the purpose of gaining sufficient heat to hatch the eggs, a process which is much aided by the extreme thinness of the membrane covering them.

Art. IX.Description of a New Species of Moth (Pasiphila lichenodes).

[Read before the Wellington Philosophical Society, 8th September, 1886.]

The genus Pasiphila is a very distinct genus of the New Zealand Geometrina, containing some of the smallest moths in that division. In his monograph of the New Zealand Geometrina,* Mr. Meyrick maintains that there is but one species of this genus in New Zealand, and to this opinion I have already made objection in a paper in the “New Zealand Journal of Science”. for July, 1884, in which it was urged that at least two species had been included under the name Pasiphila bilineolata. Since then I have bred out a third form from the caterpillar state; so that, besides the species to be described to-night, there are at least three other species of Pasiphila in New Zealand. I have also, besides these, several doubtful forms; but Mr. Meyrick has admitted to me that he had wrongly included four, if not five, distinct species under the one name. As, however, he intends shortly to write upon this subject, it will be well to leave to him the disentanglement of the synonomy, as it is a matter upon which, perhaps, he alone is qualified to speak with authority. Here I take the opportunity of acknowledging Mr. Meyrick's kindness and readiness in furnishing information regarding insects sent to him.

Those that are acquainted with English moths may easily recognize the New Zealand species of Pasiphila by their likeness in size and appearance to the various species of Eupithecia, to which the New Zealand genus is closely allied. The members of this genus are small moths, usually less than an inch across

[Footnote] * “Trans. N.Z. Inst.,” vol. xvi., p. 49; xvii., p. 62; xviii., p. 184.

– 70 –

the wings, and they rest on tree-trunks or rock-faces with their wings flatly spread out, the inner half of the hindwings not being covered by the forewings, and sharing the colouring and markings of the forewings. The neuration of the forewings also serves readily to distinguish this genus, for usually in the forewings of our Geometrina, twelve veins can be counted along the margin; but in this genus, and in the next to it,—namely, Elvia—the eleventh vein coalesces with the twelfth and appears only as a short bar from the upper side of the small cell to the twelfth vein, so that only eleven veins appear on the margin.

Pasiphila lichenodes.

Expanse, 16–19 mm. General description: Ground colour glaucous-green, with finely crenulated black lines, and two conspicuous, irregular, transverse bands of light brownish-red or chocolate colour, one near the base, the other near the hindmargin.

Detailed description: Forewings with slightly arched costa, hindmargin with a slight swelling or convexity about the middle, not crenulate; ground colour glaucous-green, becoming paler with exposure. Basal area very pale pinkish or reddish-brown, bordered by a black line sharply angulated at the middle, and followed by a broad pinkish or reddish-brown band, also bordered on the outer side by a black line. This band is contracted about the lower side of the cell, so as to be nearly divided, into two unequal blotches. The centre of the wing is occupied with a broad belt of the glaucous-green ground colour, boldly angulated about the middle of the outer side. This central belt is occupied with three finely crenulated black lines, which are so closely placed that they seem almost to divide the central belt into imbricating green scales edged with black. The central belt is also bordered along the outer edge by a black line. Between the central belt and the sub-marginal line is another broad belt, of a chocolate or reddish-brown colour, sometimes divided into two unequal blotches by the angulation of the outer side of the central belt. This reddish-brown band is crenulated on the outer side and edged with a pale sub-marginal line which follows the crenulations. Between this and the margin the ground colour appears without any distinct markings. The black lines of the forewing are sometimes edged with paler lines. The hindmargin is edged with an interrupted black line. Fringe fuscous and pale alternately. Hindwings with a distinct convexity, rather below the middle of the hindmargin. Inner half with colour and markings similar to those of the forewings. Outer half paler, greyish or whitish, markings not so distinct. Below, the forewings are fuscous, with a few of the black lines showing along

– 71 –

the costal edge, while the hindwings are greyish white, with a black discal dot and a few faint lines.

This species has received its specific name because its colourings and markings seem to me to have a protective likeness to those of the thallus and thecœ of some lichens. It occurs not uncommonly in the forest about the river-bed in the upper part of the Leith Valley, Dunedin. I have collected specimens in the latter part of January; and it is not known to Mr. Fereday or to Mr. Meyrick, except from my specimens; hence its range must be somewhat limited.

I stated that I had bred out three species of Pasiphila from the larval state, and the descriptions of the larvæ are here subjoined. Specimens of the perfect insects have been sent to Mr. Meyrick for identification. There seem to be differences between these caterpillars quite unusual in the case of closely-allied species. The first and second descriptions are reprinted from the “N.Z. Journal of Science” for July, 1884:—

No. 1. Pasiphila, sp.?

“Larva smooth, green, about 10 mm. long; an indistinct dorsal and sub-dorsal stripe of darker green; underside green, with a light ventral stripe; head yellowish. Formed small rough earthen cocoons on the surface of the earth. The food-plant is Myoporum lœtum. Larvœ in March. (See ‘N.Z. Journ. Sc.,’ March, 1882, p. 95.)”

No. 2. Pasiphila, sp.?

“Larva about 12 mm. long. Colour brownish; surface very rugged; body tapering somewhat towards the head. Two pair of small dorsal tubercles about the middle, the posterior pair being larger. Oblique lateral dark markings faintly seen on the dark ground colour; below lighter. I have beaten this larva from Aristotelia, from Leptospermum ericoides, and from a mixed growth of bramble (Rubus) and Muhlenbeckia. Larva in December and January.”

No. 3. Pasiphila, sp.?

Larva loopers from 13 to 17 mm. long, with a black median dorsal line, and on each side of it a black sub-dorsal line. The whole dorsal area between the sub-dorsal lines is brown, or brownish-black, while the rest of the back is greenish-white; below greenish-white; lateral line and median ventral line, white; there are sometimes dark blotches above the lateral line, while below it the ground colour is suffused with purplish-black. The median dorsal line is often bordered with greenish-white.

The larvæ were found about full-grown, feeding on Veronica salicifolia, in the Leith Valley, Dunedin, in the beginning of April. Two of the moths were reared, one of which had the

– 72 –

ground-colour greenish, while the other was brownish. At the same time, and on the same plants, a considerable number of larvæ, resembling the above in shape and size, were collected. Some of these had the ground-colour green, with very faint dorsal and sub-dorsal lines, the dorsal area being green, or only faintly clouded with black. Others had the ground-colour green, while the dorsal and sub-dorsal lines were distinct and black, and the dorsal area between the sub-dorsal lines was filled with alternate light and reddish - brown blotches. The two last forms had their other characters as in the first-described form, and they may be immature stages, or the larva may be a variable one.

Abdomen rounded in front, slightly curved indentation, pointed posteriorly; tubercles strong, project moderately backwards and outwards; brownish-yellow, dark, oblong mark at basal indentation; brownish marks between tubercles; strong black and white lanceolate serrated hairs.

This little spider may possibly not prove to be the male of T. olivacea, but I have taken it on two occasions, at Te Karaka and Waiwera, in the vicinity of females of that species; the first mature male was taken on November 1st. Females fabricate cocoons as late as April 17th; they are spherical, 5 mm. in diameter, echinulate, of a hard, brown, parchmenty nature, four or five in number, suspended by a short pedicel; comprised within are about 80 spherical, unagglutinated, dark straw-coloured eggs. The web is small, resembles that of the Theridiidœ, the lines intersecting one another at different angles and planes; web and cocoons may be met with about hakea fences and low shrubs. The female probably obtains some protection from her remarkable form and pale coloration; in the early part of summer examples may be met with resting on the upper surface of broad leaves—e.g., apple; when in such positions their irregular forms, tinted with a pale greenish-blue and creamy-white, bear a strong resemblance to the excreta of birds.

Art. XI.—On the Work of Earth-worms in New Zealand.

[Read before the Auckland Institute, 14th November, 1886.]

Although it has become generally known, since the publication of Mr. Darwin's researches, how rapidly surface débris is buried through the action of earth-worms, the result of a few observations may, nevertheless, be worth recording, as they afford means of comparison between the work done by the New Zealand and the British species. The comparative weight of their castings, and an estimate of the number of earth-worms usually found in some of the cultivated and uncultivated lands in Auckland District were given in a former paper, “On the Habits of Earth-worms in New Zealand.”*

A section was described, the result of the work of worms, chiefly the common Lumbricus campestris, but only an approximate estimate could be arrived at as to the length of time which it had taken for the surface - charred debris to sink to an average depth of about 5 ¾ inches. The section when first exposed, in 1875, showed an average of 4 ½ inches of black vegetable mould, free from stones, etc., and a horizontal layer, nearly 1 inch thick, of charred wood, burnt marl, fragments of jasper, and pumice, lying on the subsoil, a brownish-green arenaceous clay. In October, 1883, (i.e., in eight years), the depth of mould had increased 1 ¼ inches, giving an average depth of about 5 ¾ inches above the burnt layer; during the past three years there has been an even average increase to the superficial layer of nearly 1 inch, the total depth now being rather more than 6 ½ inches.

Considering the depth of vegetable mould above the charred layer, this certainly appears to be a considerable increase for so short a period, but apparently the estimate is correct: it is in all probability to be attributed, independently of the increase of worms since the land has been in grass, to the moisture and nature of the subsoil. Worms living in lands with a moist substratum continue to work at a low level, not only during the short intervals of dry weather that occur in the spring months, but as long as there is sufficient moisture; whereas in the upper lands, during these dry intervals, the worms cease to work, retire temporarily to their chambers, coil themselves up, and remain apparently in a dormant state until rain sets in again.

On the 15th October, 1883, a layer of charred wood and broken

[Footnote] * “Trans. N.Z. Inst.,” vol. xvi., 1883, p. 266.

– 120 –

brick was strewed on the surface, above the former layer, and a similar strip of débris was also scattered in a grass paddock on the upper land, ordinary light clay soil, with a moderately hard subsoil. Although the spot selected was rather favourable for earth-worms to work in, the amount of castings ejected on the surface may be taken as a fair average for the whole field. Sheep were occasionally grazed in the field; but considering how soon small fragments disappear beneath the surface, probably their treading did not much influence the result.

Owing to there being no well-defined line between the dark mould and substratum, no estimate of any value can be given as to the probable amount of subsoil that has been brought to the surface during the past three years; but a record will be kept of any marked increase in the depth of the vegetable mould, the average depth now being about 5 ¾ inches. At the present time the section in the trench shows, the grass being shaved off close to the surface, an average of ⅞ths of an inch of brownish-black mould, free from coarse material, and a horizontal layer of charred wood and broken brick half an inch thick, forming an even line round the vertical sides. This means that in three years, or rather during the working months of that interval, through the agency of earth-worms, ⅞ths inch of mould has been added to the superficial layer—mould that has been enriched with vegetable and animal matter, passed the bodies of the worms, and ejected as castings on the surface.

This annual working of the superficial mould effects a remarkable change in the character of our fern-lands in the course of time—that is, after they have been cultivated, or, more especially, if left in permanent pasture, for 10–15 years, and have become fairly stocked with worms. There are, no doubt, other agencies that, under the circumstances, tend to improve the soil, but, more particularly in the case of permanent pastures, only minor agencies.

From the number of earth-worms that live in most of our old pasture-lands, it is evident—independently of the experiment given above—that, as Mr. Darwin has shown, the superficial mould must pass over and over again through their bodies, and be brought to the surface. It is hardly necessary to point out the value such work must be to the agriculturist, especially when taken in conjunction with the loosening of the subsoil by their burrows and chambers, which in time become more or less filled up with their castings and the dark viscid linings of the walls. These moist and nourishing galleries, penetrating, as a rule, to a depth of 6–15 inches beneath the surface, must tend to draw the roots of the vegetation to a depth that they would not otherwise attain.

– 121 –

The test in the lower land (mentioned above), a black arenaceous loam, was submitted to rather severe conditions—that is, the coarse wood-ashes and broken brick were spread over a thick sward of cocksfoot grass, from which stock is always excluded. Last September, when the strong grass was shaved off close to the surface and a trench opened up, the section, in the vertical sides of the walls showed that all the débris was buried beneath an average depth of rather more than ⅜ths of an inch of mould; the layer forms a horizontal line ⅞ths of an inch in thickness, but most of the débris is more or less entangled amongst the roots, consequently does not represent a compact and well-defined line; some of the fragments of brick, about 1 ½ inches square, weighing over loz., have sunk about ½ inches beneath the surface. This irregularity is to be attributed to the fragments having remained entangled amongst the grass for a more or less length of time, consequently buried at various intervals. It will be observed that there is a difference of about half an inch between the increase to the superficial layer in the upper and lower lands, which is easily accounted for: it was an oversight on my part that, when the débris was scattered over the latter, a portion of the grass was not skimmed off; this would have given the worms a fair chance of more rapidly burying the material thrown over it; however, this error will be remedied before next winter.

The larger of the two stones mentioned in the former paper, which was laid on the turf in May, 1876, when raised on the 15th October, 1883, left a cast 2 inches in depth; when again examined on the 26th September, 1886, it was firmly embedded, and required some force to raise it; the most protuberant point was 3 inches beneath the level of the surface, the raised margins being removed; the flatter portion had sunk 2 6/10 inches; worm burrows were numerous beneath. The smaller stone, which was placed near the former in September, 1882, sank in thirteen months 1 inch; on the 26th September of the present year it had attained a depth of 2 inches below the general level of the ground; its convex margins were partially covered with worm castings and grass; it will, if left undisturbed, soon become entirely buried beneath the surface. It is well, perhaps, to bear in mind that under favourable conditions, through the agency of earth-worms, it is possible for a stone 6 ½ inches long, 3 ⅜ inches broad, and 3 ⅜ inches in thickness, to disappear below the surface of the ground in about seven or eight years.

The experimental stones laid on the turf on October 15th, 1883, when recently examined gave the following results:—

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

No. 1, triangular block of trachyte, 6 inches high, when raised left an impression 6 inches long, 4 4/10 inches wide, depth below general level of the ground 1 2/10 inches.

– 122 –

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

No. 2, 4 inches in thickness: cast, long, 6 8/10 inches; wide, 6 inches; slopes from surface to a depth of 1 2/10 inches.

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

No. 3, average thickness 4 inches, bottom irregular: cast, long, 8 inches; greatest width, 5 5/10 inches; average depth, 1 4/10 inches.

These stones were surrounded with the usual margin of fine vegetable mould, were rather firmly embedded, and had not been raised since they were first laid down; beneath were numerous worm-burrows.

The researches which I have carried out during the last three winters, with the rather vague hope of affording some evidence that earth-worms possessed, to a limited extent, a sense of direction (for it may be assumed that there is such a sense), have, owing chiefly to the unnatural conditions to which they had to be submitted, not been by any means conclusive.

Although it was very improbable that, when worms left their burrows and wandered about for considerable distances after more or less heavy rain, they ever returned to them, as it was possible that on ordinary nights, when they sometimes only wander for a short distance from their burrows in search of food, that they might intentionally return to them, I thought it worth while to endeavour to determine if such was the case, as earth-worms certainly appear not to be devoid of a low form of intelligence. In the centre of boxes, 2 feet square, a small hole was pierced, a shallow vessel was placed beneath the orifice, filled with moist siliceous sand, with the hope that it would be the means of compelling the worms to come to the surface in search of food. Four or five of our large Lumbricus uliginosus were placed within each box—the boards having been well damped. As is almost invariably the case when worms are placed in confinement, in the first instance they travelled round the margins (when placed in pots containing well-pressed earth they finally force their way down the sides, rarely towards the centre); after attempting for 15–20 minutes to burrow into the boards, or scale the walls, one or two of the more vigorous, possibly more intelligent, struck out across the centre; after a few traverses they finally, as a rule in about 30 minutes, discovered and entered the artificial burrow. About as often as not, all the worms had found out the entrance before the morning; but in some instances, part or all, after crawling for a time round the sides of the box, finally huddled up into a corner, and would have died there, had they not been removed. Although tempting baits consisting of their favourite food, onion bulb, etc., were placed close to the mouth of the burrow, the worms rarely came to the surface; when they did, and left the burrow to wander about, apparently in most instances they never

– 123 –

returned to it, but remained alongside the walls. In hopes of affording them greater inducement to return, tufts of grass were placed in the centre; but the result was not satisfactory, as they appeared never to leave them, probably owing to there being no inducement for them to do so. Although the fact that some of the earth-worms after coming to the surface and wandering about returned to the burrow, by no means proves that the act was intentional, the fact that the majority of them never did so, hardly disproves the possibility of their possessing sufficient intelligence to do so. Considering the unfavourable conditions to which they were submitted, and that they must necessarily have been weakened through want of food, it could hardly be expected that they would under the circumstances have acted with the same freedom and intelligence as when in their natural haunts.

Art. XII.Notes on New Zealand Earth-worms.

[Read before the Wellington Philosophical Society, 4th August, 1886.]

The habits of New Zealand earth-worms receive the smallest share of attention from naturalists of any group of our native fauna. This is to be expected, as the study of worms requires much time and patience, and the attractions in a young country among the higher groups is greater, especially one like New Zealand where so many anomalous forms exist, that little time is given to some of the lower orders. Some notes, therefore, on earth-worms, made during eleven years of almost daily experience with them in several localities in the South Island, will contribute a little towards a knowledge of their habits.

As the habits of some of our earth-worms differ considerably from others, I propose to give notes on each species separately, of all I am acquainted with, and the locality where I have collected them. This will enable other workers who may be studying earth-worms in various parts of the country to compare their own observations. This appears to me a sound method of working out perfectly the habits and distribution of all species.

Like other groups of animals, earth-worms vary in their habits, size, and colour, according to the nature of the soil or situation they inhabit; but, so far as I have ascertained, our worms differ, distinctly in some respects, from the British species, so ably treated by Mr. Darwin, in the construction and form of their burrows. I think I will be able to show that New Zealand earth-worms, whether kept in pots in confinement or

– 124 –

in their natural state, differ much in their economy from the British Lumbricus; but more especially in the peculiar semicircular and distinctly branching burrows they construct. This, however, does not apply to all species, as there are others which cannot be said to construct any particular form of burrow: those species, for instance, which live and bore, or burrow, in every direction in loose decaying vegetable matter, or rotten wood, in the bush. The habit of lining their burrows with leaves or other materials is absent with worms in Canterbury and Otago. Mr. A. T. Urquhart, in an excellent paper “On the Habits of Earth-worms in New Zealand,” * has shown that the habit obtains with worms inhabiting the Auckland District. He has also shown that they are content with drawing in leaves to the mouths of their burrows; but he thinks they are chiefly for food. The same habit prevails with worms in Canterbury and Otago; but here in the South, where they live beneath gravel-walks, they draw small stones over to conceal the mouth of the burrows, when not protected by the usual covering of viscid castings. My notes have been gathered in the country between the Rivers Rakaia and Kakanui, and I do not venture to treat of worms beyond the limits of these rivers, although no doubt they will be found to vary little.

Between the two rivers, a distance of 115 miles, worms abound in all the forests, hills, downs, and plains; in some districts they are abundant, in others they occur sparingly. Wherever a clearing is made in the forests they are very active in favourable weather, and throw up immense quantities of castings on the surface. Worms increase in numbers more rapidly in forest clearings than in open pastures; it is due to the mould containing much decayed matter, which they so much relish. They are plentiful beneath dense beds of ferns, or any undergrowth in the forest, and occur sparingly on all the diverging spurs of Mount Peel, Rangitata, up to 4,000 feet. If a prostrate log in the bush be rolled over, large numbers of worms of several species will sometimes be found secreted beneath it; the same may be said of flat stones, and slabs of wood. About farm homesteads, where old bags are left lying on the ground, worms gather beneath them in great numbers, especially during moist or wet weather. They appear to prefer the shelter of rotten bags lying on the surface; it is probably for warmth, as they do not generally burrow beneath them.

In old forests, where small streams flow through them, sections of considerable thickness are often exposed in their banks; at depths varying from 10 to 40 inches a distinct layer

[Footnote] * “Trans. N.Z. Inst.,” vol. xvi., pp. 266–275.

– 125 –

of black mould is visible. These layers appear to have been once the open land inhabited by worms, before the forest spread over it. As the vegetation flourished, the decaying matter from it in the form of leaves, bark, and rotten wood, assisted by the actions of worms, made up in time the superficial mould as we find it to-day in forests. The Canterbury Plains, near the north terrace of the Rangitata River, is covered in some parts with 2 ½ to 4 inches of brown friable mould. It is doubtful whether worms ever existed there in any numbers, as the greater number of various-sized stones lying on the surface exhibit few signs of sinking, and must have remained on the surface for many ages. A few are slightly embedded, while others show a slight impression as if produced by their own weight; the same will be noticed by many on other parts of the Plains, in passing over in the train. These portions of the Plain are exposed to fierce north-west winds, which blow during the spring and early in the summer with terrific force, down the gorges of the Rangitata and Rakaia Rivers, carrying away the finer mould, and depositing it over the Plains along the eastern or lower side.

Worms greatly dislike wind, and, so far as I have ascertained, do not rise to the surface to change quarters, to feed or pair, during dry or cold windy nights, unless accompanied by heavy rains, when they are sometimes flooded out of their burrows. It is during the spring and summer that worms are most active; on mild nights they rise to the surface and pair, and can often be seen lying long after sunrise. I am, therefore, inclined to believe that their absence from those parts of the Plains is chiefly due to their exposure to the dry and fierce “nor'-wester.” On some parts slight depressions occur. After heavy rains small lakes are formed for a time, but generally disappear in a few weeks. The mould in such places is much deeper, and worms more numerous, than on the more stony parts. Although in a few places stones are not seen on the surface, they have sunk through the action of worms, and lie only a few inches below the scanty covering of turf.

Near the banks of the River Hinds, nine miles north of the Rangitata River, where the thick tussock grass breaks—or a few years ago broke—the fury of the wind, worms begin to be more numerous, and along the sea-board for miles inland the land is deep and strong. It is also comparatively free from stones, and worms are abundant. The common Acanthodrilus uliginosus was a few years ago the more numerous. Another larger and undescribed species, of very sluggish habits, is found near the edges of permanent swamps. The other species occurring on the Plains are Endrilus annulatus, E. campestris and E. levis, the first-named of the three being the commones. Beneath the great terrace on the north side of

– 126 –

the Rangitata, there is some excellent land, where worms exist plentifully, and at all seasons, when the weather is favourable, throw up large quantities of castings. The soil, excepting in the swampy parts, is slightly sandy, and probably has been blown on to it from the river-bed by the strong wind. I have no doubt that the great depth of rich mould along the sea-board of Canterbury has been added to considerably by the storms of fine mould blown by the “nor'-westers” from the hills and western portions of the Plains. Some of the stony parts that have been ploughed within the last eight years, and sown down in grass, show signs of worms increasing, by the greater number of castings thrown up annually. When cutting the crops of grain, farmers put little value on the straw, and set the knives of the reapers to clear the stones on the surface. When the grain is threshed out, the straw is sometimes left to rot in large heaps. When trodden down by cattle or sheep, the ground around the mass soon becomes inhabited by Endrilus levis.

Agriculture is favourable to the increase of worms. It is due to the land being loosened by the plough and sweetened by the atmosphere. Worms are the natural fertilizers of the soil, and in favourable weather are constantly replenishing it by the addition of fresh castings. The enormous area of land in New Zealand at present sown down in English grass, will be greatly enriched in a few years for future cropping, through the action of worms. In mild weather, and at all seasons, worms eject more castings on bare patches free from grass, sheep tracks, or well-beaten paths across fields, than on ordinary pasture land, even when many years in grass, but no more than on old lawns that are kept well-mown and rolled. I think this can be explained by the paths and lawns being firm and compact, and having no interstices where they can eject their castings. If burrowing afresh in solid ground, they are compelled to void all the mould they swallow on the surface.

During heavy rains, pools of water are sometimes formed on bare paths; as the weather becomes fine, and the water drains away, a fine sediment or “film of mud” settles on the surface; worms are then very active, and in a few days almost cover the site of the pool with dark mould. As the worms work vigourously, and appear especially to relish the mould, it is probable that many nutritious particles accumulate in the pools, and sink into the earth with the water as it drains away.

Worms throw up castings abundantly in corn-fields, between the stalks of grain, but not for some time after the land settles down; heavy rain settles the ground in a few days. While it remains loose, the worms eject their castings in any crevice. They delight in moist but not wet land, and in dull mild days throw up castings as well as during the night. I first observed this by castings appearing on a tennis lawn through the day,

– 127 –

that had been well rolled in the morning. Some days more are thrown up than others. On those days they are ejecting mould, birds can often be seen flying on to lawns and drawing worms from their burrows.

Some curious sections can be seen on some of the low flats of some Canterbury rivers, notably at the Rakaia, Hakatere, and Tungawai. They consist of thin alternate layers of fine sand and mould. After the deposition of the thin layer of sand, the worms appear to have thrown up a few inches of mould, when another layer of sand was again and again deposited over it. Heavy rains also wash down quantities of fine silt and clay from the clay-banks or “facings” at Albury, and deposit them over the flats below. The worms in a short time throw up abundance of castings; the clay soon becomes perfectly mixed with the mould, and forms land of great depth and good quality.

The cold and wet season of 1884 was specially suited to the actions of earth-worms. Many English grass paddocks adjoining the Haketere or Ashburton River, and broken up eleven years, were daily closely covered with fresh castings. In some parts the whole surface had the appearance of having been covered with a thin covering of dark mould. Many of the castings were of considerable size, and measured in height from ¼ to 1 ½ inches. Owing to the continuous wet weather, it was impossible to collect and weigh them accurately from a measured space, but the amount of mould thrown up must have been considerable, compared to other seasons. On the low undisturbed land, elevated only a few feet above the river, fresh castings were numerous, some portions covered with a fine layer of sand had also a sprinkling of them on the surface.

Worms living in gardens, in cold weather, often cluster together into any piece of rank, loose, or half-decayed manure buried in the soil. Such no doubt is warmer and more pleasant to their bodies; it is also more porous, and allows the wet to percolate through. In rich well—worked gardens, Endrilus annulatus and E. campestris attain their largest size: both species often assume a blackish hue; the former in colour, when inhabiting pastures, is whitish-pink; the latter is generally brownish-red. Both species, with Endrilus levis, are often found between the outer leaves of cabbages and lettuce, and consume much of the softer parts. They cling in great numbers around the stems of blanched celery, and nibble at the more tender parts, often proving very destructive. Although A. uliginosus is found in gardens, they prefer the shelter of large trees in the orchard, or strawberry-beds, to the more cultivated parts, and are not so numerous as the three last-named species, which certainly are the commonest garden worms. They do much injury in flower-pots, and impede the growth of plants by boring or burrowing through the mould,

– 128 –

disturbing and consuming the tender roots, and absorbing all nutritious particles from the soil. If pots are thus infected, and the plants carefully turned out, it will be seen that they keep chiefly to the sides of the pots. The burrow or track against the side is generally open. The tender feeding-roots can be seen “pressed into the walls,” and their actions choked in the viscid lining of the burrow. They deposit their castings among the drainage cracks beneath the mould, and, if not removed, will sometimes effectually choke the drainage. Worms, especially half-grown specimens of Endrilus annulatus, occasionally hibernate in pots, even when the conditions are favourable for their actions.

Some of our worms present some problems, which, as yet, I have not been able to solve. I have already mentioned a large undescribed species existing in a few swampy places on the Plains. Here, near Oamaru, it exists as a more diminutive species, although the conditions appear equally favourable for its development. In one particular swamp, on the south side of the Rangitata Gorge, it attains its maximum size, some specimens measuring 13 and 14 inches, and varies much in colour from each locality, from yellowish-white to dark reddish-pink.

The diseases of earth-worms are little known; yet they are subject to some of a virulent type. I have seen a few individuals of A. uliginosus with hard excrescences on different parts of their bodies. They appear to be painful to the animals, as the slightest touch on one of them causes the worm to shrink. The disease first appears as a small hard pimple, and increases gradually in size. It sometimes almost surrounds the worm's body. At this stage the swelling softens and opens, and the intestines protrude, tinged with blood, when the miserable creature finally rots away.

Mr. Darwin, in his “Vegetable Mould,” page 14, remarks: “After heavy rain succeeding dry weather, an astonishing number of worms may sometimes be seen lying on the surface.” He believed that they were “already sick,” and that their deaths were “merely hastened by the ground being flooded.” He thought if they had been drowned “they would have perished in their burrows.” After many years experience with worms, under all circumstances, I am fully convinced that severe and protracted droughts are both distressing and destructive to them. When drought sets in they are compelled to hibernate, excepting those affecting the edges of permanent swamps. If it be severe, the mould becomes so intensely hard that they are unable to escape, and many perish with exhaustion. If the drought be succeeded by heavy rains, many survive; while some appear to have only sufficient strength to struggle to the surface and die from the same cause, probably accelerated in their weak state by a little cold or exposure. I think this is borne

– 129 –

out by the appearance of their limp and emaciated bodies; but, whatever may be the cause of their deaths, I am of opinion that they die more from the lack of the necessary moisture in the mould they inhabit, than from actual disease.* Mr Urquhart, who has paid some attention to this subject, and who collected worms roaming about after heavy rains, says that they were certainly not all sick, as he obtained healthy as well as sickly and dead worms; but in the case of the healthy ones they were no doubt flooded out of their burrows, and searching for drier ground when picked up. However, that worms are sometimes drowned there is no doubt, as any one can observe after heavy rains. When the water sometimes forms large pools in paddocks, numbers of dead worms are seen lying on the bottom. If it occurs in the spring or summer, the little grey Tern (Sterna antarctica) soon detects them, and small flocks hover and circle about the pools, dipping into the water every few minutes and picking up the dead worms.

Protracted droughts do incalculable injury to the land, not only in destroying worms, but in preventing their actions from replenishing it. The summer and autumn of 1885 and 1886 have been the driest on record, and the most disastrous to earth-worms, that of 1884 the coldest and wettest, but well suited to their actions and the most beneficial to the land.

Mr. Urquhart states that the greatest enemies of worms in the district of Auckland are the Limosa baueri (Var. Redrumped Godwit) and Larmus scopulinus (Mackerel Gull). Here in the South, undoubtedly their strongest enemies, excepting in the more settled districts, are the Weka (Ocydromus australis) and Swamp Hen (Porphyrio melanotus). Both species, being of nocturnal habits, come in for the lion's share. Both the introduced blackbirds and thrushes consume immense numbers. The old adage, “The early bird catches the worm,” is most appropriate when applied to both species. The abundance of worms in settled districts, combined with their habit of lying paired, or roaming about on the surface after daybreak, may be said to be one of the chief causes favouring the great increase of both these English songsters. They, however, do not lose their finer relish for strawberries and other fruits, as they have already gained the same ominous name in this

[Footnote] * Mr. Darwin has fully discussed the effects of an English winter on earth-worms. After observing their movements on the surface, he remarks: “On these occasions, very few dead worms could anywhere be seen,” and continues, “on January 31st, 1881, after a long-continued and unusually severe frost, with much snow, as soon as a thaw set in the walks were marked with innumerable tracks;” but no further mention is made of dead worms

– 130 –

respect as in England.* In the springtime, when lands are ploughed, millions of sea birds, coming inland to breed, follow the plough, and subsist for weeks and months on worms. Several species of birds come a long distance from their nesting-place to follow the plough, and obtain food for their young. When mild weather, with sunshine, succeeds heavy rain, worms often lie in loose mould near the surface. The weka is then very busy, and digs them out with its powerful bill, and consumes great quantities. I have dug up a number of worms, from time to time, minus their tails. I think that during the process of ejecting their castings they are sometimes attacked by birds, which with a quick snap of their beaks tear away a portion of the worm's body. If the tail of a worm be seized with the fingers, when protruding from its burrow, it has great power, and it would be almost impossible to extract it without injury. If only a few segments of the tail are removed, the worms apparently suffer little or no inconvenience, and, if placed in pots, continue active and throw up castings.

The burrows of New Zealand earth-worms form a curious and striking contrast to the British species, described by Mr. Darwin in his valuable work on “Vegetable Mould.” He says, “they run down perpendicularly, or, more commonly, a little obliquely.” He doubted if they branched in solid ground, and adds: “As far as I have seen this does not occur, except in recently-dug ground, and near the surface.” Mr. Urquhart, in his paper already mentioned, states that he “met with instances in which the burrows branched in solid ground, but the branching merely consisted of two short lateral passages at the termination of the burrow, leading into two distinctly separate chambers,” and adds, further, “it is not unusual for two separate burrows to terminate in the same chamber.” Mr. Urquhart, however, does not name the species inhabiting these forms of burrows.

I have already stated that our worms construct semicircular and distinctly-branching burrows. I will select those of A. uliginosus, as it is a common species, and its burrows large. They can be more easily examined than those worked by the smaller forms. In order to examine them perfectly, I have been in the habit of stripping off the turf or covering of

[Footnote] * Probably the best introduced bird is the English starling (Sturnus vulgaris), which is increasing at an unprecedented rate. In settled districts it can be seen in troops of many thousands, busily picking over the ground infested by the larvæ of Odontria striata. Besides consuming great numbers of worms, it bids well at present to exterminate the native Locustina, as they have almost disappeared from districts where the birds are numerous. It would, therefore, be well for collectors to secure abundance of specimens in all districts where the starling is likely to increase.

dead grass with a sharp spade until the mouths were exposed. I then pour a small quantity of a weak saturated solution of corrosive sublimate into the burrow. No sooner does it come in contact with the animal's body than it starts to the surface. Sometimes they rise 12 or 15 inches from the mouth of the burrow where the solution is poured in, but invariably at the mouth to which the worm's head is directed. I never saw one leave its burrow tail first, except when it was a new one in course of making.

Another method of testing the form of these burrows is to insert a fine pliable twig (a weeping-willow answers well) into them, passing it through from one mouth to the other. It is at times difficult to do this, unless the solution be used, as the worms will often refuse to leave the burrow, or when both mouths are close together on the surface, or branches in other directions. When the twig is passed through, it is then easy to dig away the mould or clay on one side and examine the burrow. The two or more mouths vary from 2 to 18 inches apart. When they meet close together on the surface, the worms often lie in the morning with portions of their bodies exposed, with head and tail down each mouth of the burrow, as if enjoying the sun's warmth; but the habit causes the death of many, as the keen eyes of the weka and swamp-hen detect them, and the birds snatch them from their burrows.

When they are working in a considerable depth of rich mould they do not always line their burrows, especially in mild weather. Others, again, are partially lined, being dotted over sparingly with “small globular pellets adhering to the walls.” When living in clay or clayey land the walls of the burrows are thickly lined with viscid earth, and can be examined perfectly, as the dark lining of the burrow contrasts well with the clay. The latter being colder, accounts for the greater thickness of lining. In depth, the burrows vary from 4 to 20 inches; those of the young worms are generally about 3 or 4 inches. It is difficult to dig up whole burrows without fracturing them, yet I have succeeded in raising some perfect ones, which I will forward to the Colonial Museum. When frosts or droughts set in, many of them hibernate for a time; the chambers in which they hibernate are sometimes excavated on one side of the burrow, or a few inches from its walls, but commonly in the middle, and form an enlargement. The chambers are always lined with viscid earth; in addition to this they are often saturated with slime from the animal's body, this forms a cool and slimy bed; they then roll themselves up in the form of a ball, or lie coiled in a circle, with the head in the centre. I have dug them out tied in a perfect knot, or in the form of a running noose, with head and tail placed together. After hibernating for some time, especially in

– 132 –

dry weather, many of them become pale and almost transparent; their bodies also become limp, compared to those that remain active in moister places.

Where two or more worms are found in one burrow, or in separate chambers attached to or leading from it, it can only be explained by some finding their way into them during the night, when roaming about on the surface, and when the mouths of the burrows are open. I have observed that when worms are numerous in solid ground, their burrows often enter or run into each other; they then have the appearance of branching burrows, but the difference can be detected, as a perfect one is either semicircular, or branches gradually like railway points, usually but not always at the bottom, or turn, and rises again to the surface. If worms are about to hibernate, they sometimes descend perpendicularly to a considerable depth, and turn a few inches horizontally before they excavate their chambers; the mould is generally voided in the channel leading from the main burrow, and effectually shuts off the worm from any contact with the cold or dry air.

In some of the branching burrows may often be seen quantities of fresh castings packed tightly into them. The difference between dark mould washed in from the surface, or from the broken walls of a burrow, can be distinguished from castings voided intact, as the latter retain their perfect vermiform shape for a considerable time. There is no doubt whatever that the New Zealand earth-worms “use old burrows for the purpose of voiding their castings in,” as abundance of them can be found in clay, or clayey lands, perfectly packed with them, both fresh and old. The habit of voiding castings, or pairing in their burrows, must tend to the preservation of worms in districts where their enemies are numerous.

During the last summer, undoubtedly the hottest and driest on record in this province, the sun cracked the land which these worms inhabit to a great depth. In order to ascertain the depth they burrowed under the circumstances, we dug several holes, and found them chambered at from 20 to 49 inches from the surface.

Early in September of last year one of the ploughmen informed me that he was ploughing a piece of land on the banks of the Waiareka Creek which contained great numbers of large worms. I went out next day, and followed in the wake of the plough, collecting specimens and examining the burrows. The land was the same peculiar adhesive mould already mentioned, and the worms were numerous and large. Previous to this the weather had been mild, and suited to their actions. The burrows were very perfect, nearly all being of the semicircular form. The air echoed with the delighted cries of gulls, stilts, and terns, all eagerly devouring the large worms.

– 133 –

In regard to the number of worms living in gardens, cultivated fields, and undisturbed Native land, I have made many tests. Worms like naturally rich and even strongly-manured land, but occur plentifully in some districts in poor soils. In an old kitchen-garden on the Rangitata they averaged 7 per square foot; in a similar one at Albury they averaged 8 per square foot; and in another in North Otago, cultivated seventeen years, the average was 7 per square foot. Worms are more numerous in old pastures than in gardens; in some paddocks in the Waiareka Valley they vary from 5 to 16; at Ashburton, on the Plains, paddocks broken up ten years had an average of 8 to each square foot, but they are often found twice more numerous in some parts of the same paddock than in others. In the winter of 1884 we were planting some pines on a piece of Native land, where A. uliginosus was plentiful; at six different places on the slope we dug out a square yard, and counted the worms, which numbered in each as follows: 11, 8, 7, 13, 9, 6; but in some places, lower in the valley, they are more numerous.

The habit of worms rising to the surface and leaving their burrows, caused by beating the soil or other disturbance, is peculiar to two species, Endrilus campestris and E. annulatus. As far as I know, this only occurs on loose ground, particularly in gardens or swampy land that trembles when treading on it. Occasionally, though rarely, they do so in pasture, when the land is soaked after heavy rains; but no manner of beating, or treading, will drive them to the surface in fine weather, either in pastures or on lawns, when they are a few years old, and the ground solid and favourable for their actions. The reverse is the case in loose garden mould: almost any piece not dug for several months, if trod on, or beaten with a spade, will bring some to the surface. This instinct is a subject for speculation; and after experimenting with a view to ascertain the cause, I have no doubt that the sudden breaking or crushing of the burrows causes the worms to extricate themselves and rise to the surface. Both are very sensitive and timid species, and the sense of fear highly developed in both. This considered, I think that any sudden shaking of the mould, or collapse of the burrows, would cause the animals instantly to free themselves, by rising to the surface; but possibly the habit may be acquired from living in loose mould.

I have never lived long enough in one locality to experiment with the sinking of large stones or other bodies, through the actions of worms; but Mr. Urquhart, from experiments made in the Manukau District, has shown that they sink sooner in New Zealand than in England; the gravel on garden walks also sinks much earlier in this country, but the greater number of worms will account for this. There is no doubt that the

– 134 –

accumulation of mould increases more rapidly in our climate than in countries where the winters are long and severe.

The habits of our earth-worms kept in pots differ also from the British species, and are the same highly sensitive animals. If the pots are placed in the open air, they plug the mouths of the burrows with castings, but never plug them or line the burrows with leaves or other materials. They consume fresh or tainted meat; they especially relish the small soft leaves of the common chickweed (Stellaria media). As many as four and five are often drawn into one burrow in a single night. They nibble at almost every variety of mixed fruits or vegetables placed on the pots, and swallow quantities of pounded glass, brick, oyster-shells, and small stones, to aid in the trituration of their food. They are greatly benefited by a change of fresh mould occasionally, and burrow vigorously through it for days after, as if searching for the more nutritious particles it contains. When worms are kept in a limited quantity of mould they become weak and sluggish in their habits. If experiments are tried with worms in penetrating hard compressed soil, or sand, specimens of the same species fresh from the pasture will penetrate it much quicker than those which have been previously kept in confinement. When the mould in pots is pressed down hard, the worms construct the most perfect semicircular and branching burrows, and line them perfectly with viscid castings. The best results are obtained by putting one worm in each pot, according to the size of the animal, but the larger the pot the better, if obtainable.

The following is some account of six species, the other two recorded species (Megalosolex antarctica and M. lineatus,) I have had no experience with:—

Acanthodrilus (?) uliginosus.

Lumbricus uliginosus, Hutton, “Trans. N.Z. Inst.,” vol. ix., p. 351.

Acanthodrilus (?) uliginosus, Hutton, “N.Z. Journ. of Science,” vol. i., p. 586.

Professor Hutton gives this species as 9 inches in length. This is about the average size, although it attains the length of 12 inches. It appears to be distributed over the whole length of the islands, as Mr. Urquhart mentions it occurring in the Auckland District; and I bear from a correspondent that it is plentiful at Riverton, in Southland. In some districts, in suitable soils, it is exceedingly abundant. It attains its greatest size on low-lying, moist flats, or near the margin of sluggish streams, where it is not much disturbed by the plough. It is sparingly found in poor and stony soils, but does not thrive so well as or attain the size of those living where the land is richer and moist. It is a more active species than its larger congener, and during dark damp nights in spring and summer they leave

– 135 –

their burrows in prodigious numbers, and move about on the surface; some are in search of food; some to pair; while others seek new ground to burrow afresh. The nights they appear on the surface, the weka and swamp-hen commit great havoc among them. In some parts of the Waiareka Valley, near Oamaru, the land is intensely adhesive; if ploughed when a little wet, it adheres to the plates of the plough and causes it to stick fast in the furrow. In this particular mould this large species exists in enormous numbers, and attains a great size. From the adhesive nature of the mould, the castings they eject retain their size and form for a long time, and are not so easily defaced or washed away by heavy rains as those thrown up on friable loam. Some thrown up by the larger worms resemble the one figured by Mr. Darwin,* but not so large or perfect. I have not seen an analysis of this mould, but after experimenting with a number of the worms, by handling the animals with the bare hand, and mixing the secretions with the other soils, I am of opinion that its tenacity is chiefly owing to its being saturated with the intestinal secretions of these animals. The same result is obtained by placing a number in a large flower-pot containing friable loam; in a few months it is changed to a rich adhesive mould. The land, however, is well suited for growing wheat, a yield of 70 to 80 bushels per acre being commonly obtained on it. As winter approaches, any castings standing up are soon pulverized by frost, and form small heaps of fine mould on the surface.

Acanthodrilus, sp. nov.

This undescribed species is the largest yet discovered, and although I have stated that it varies in size and colour in different localities, individuals are met with much larger than the largest forms of A. uliginosus. It is found living chiefly in clay, or clayey soils, and its habits are more sluggish than the last-named species. It is limited in its range, being confined to a few places in the districts I have examined. In one spot, a few miles below the Rangitata Gorge, the largest forms are found. Its colour in this locality is reddish-pink. It also occurs in a few places on the Canterbury Plains. At Oamaru I find it in one place, a small swampy patch of Native land; but here it exists as a more diminutive species, and never attains the size of those living in the two other localities. Its burrows are peculiar, as they are more commonly found running horizontally, than perpendicularly or obliquely. They appear to burrow in this manner when inhabiting solid clay. The burrows are of no particular form, but wind in all directions, generally, horizontally, and near the surface, especially if the clay be wet.

[Footnote] * “Vegetable Mould,” p. 129.

– 136 –

When living in deep clayey land, as at the Rangitata Gorge, their burrows have often two distinct mouths, and frequently resemble the letter Y. They work deeper in the mould, usually preferring the clayey subsoil. The dark superficial mould is intermixed with clay, voided in old chambers by the worms. Sometimes the burrows run a few inches horizontally at the bottom. I have never observed this species hibernating, but the habit of living in damp clay may account for it not doing so.

Endrilus (?) levis, Hutton.

Lumbricus levis, Hutton, “Trans. N.Z. Inst.,” vol. ix., p. 351.

Dygaster (?) levis, Hutton, “N.Z. Journ. of Science,” vol. i., p. 586.

This species abounds plentifully in heaps of rotten dung, or any decayed vegetable matter. It attains its greatest size in the bush, among moist beds of dead leaves, or leaf-mould, when its colour is paler and very distinct. It is also found, as Professor Hutton states, “in gardens and fields,” and is “a variable species, sometimes of a greenish hue.” If seized with the fingers, or touched in any way, it secretes a yellow fluid having a fetid odour, which is most distasteful to birds. Caged birds will generally reject it if any other food is obtainable. It is common in Peel Forest, in parts where the mould is deepest and moist. It is somewhat sluggish in habit; and numbers can often be found lying paired beneath slabs of wood, or rotten logs, in which it sometimes bores between the bark and decaying wood, generally on the under surface. It delights most in wet decomposing manure. I have observed it in a matted mass, in the bottom of an open drain leading from a gentleman's kitchen, living in the slimy, soapy pulp. After much wet weather, which causes celery to rot in the trenches, they cling to and nibble at the tender or rotting parts. Where numerous, the rotten celery occasionally partakes of their offensive odour.

Endrilus (?) annulatus, Hutton.

Lumbricus annulatus, Hutton, “Trans. N.Z. Inst.,” vol. ix., p. 352.

This species is the commonest form in all the localities where I have examined; it abounds in gardens and pastures, and is met with in almost every quality of land, from peaty soil on low flats to dry friable loam several thousand feet up the slopes of the ranges; it increases rapidly as the land becomes broken up. It is a very variable species in colour and size, being met with from pale-pink to brownish-black. When living in peaty soil they are pale, and never attain the size of some specimens living in well-manured gardens. When heavy rains fall on newly-dug ground, they often leave their burrows and move about on the surface, leaving a distinct track behind them. This species has the habit of lying closer to the mouth of its

– 137 –

burrow than any other, and is more consumed by birds. It is about 5 to 1 more numerous than any other species. In the summer, during damp mornings, it may be seen moving about on the surface of lawns or pastures, moving its head to and fro, searching for food among the short grass. It has the habit of lying or working close beneath the surface of the mould; this occurs in fine weather after heavy rains, it then falls an easy prey to the weka, which roots them out with its strong bill, and consumes vast numbers. Hundreds can sometimes be seen dead in ditches, or in paddocks where water lodges on the land, after storms of rain.

Endrilus (?) campestris, Hutton.

Lumbricus campestris, Hutton, “Trans. N.Z. Inst.,” vol. ix., p. 352,

Dygaster (?) campestris, Hutton, “N.Z. Journ. of Science,” vol. i., p. 586.

This species is found plentifully in gardens; more so in old ones cultivated some years, than in gardens recently made. A very variable species: Professor Hutton gives its colour as “reddish or olivaceous-green.” In good garden soil it is sometimes almost black, with the clitellum “reddish-brown” and very distinct; I have collected specimens on poor soil clear red. If held before the light of a lamp at night, it is almost transparent. It is a very sensitive and active form; it prefers medium dry to wet land; in gardens in summer it collects into strawberry-beds or under the shade of trees in the orchard: it appears to have a strong liking for both cos or cabbage lettuce, as I find it often between the inner leaves, nibbling at the tender edges. It delights to live in the rot-heap of kitchen gardens, where the refuse of all vegetables is thrown to form manure; it climbs through the heap in all directions, subsisting on the decaying matter. Common in some districts in the open land.

Megalosolex sylvestris, Hutton, “Trans. N.Z. Inst.” vol. ix., p. 351.

This species is plentiful in some places in Peel Forest, It lives in the rotten centres of prostrate trunks, or in the bark. It appears to prefer the dampest parts of the forest. It occurs in the fine mould which often accumulates around the bottom of the stems of tree-ferns. Colour, “dark red-brown.” The young is generally lighter in colour. If placed on level ground, it has a curious habit of wriggling or twisting itself violently about.

The actions of earth-worms on the Canterbury Plains in former times is of much interest, as a little reflection will show that the accumulation of the mantle of mould now covering them must have proceeded at an exceedingly slow rate. The

– 138 –

enormous mass of shingle and sand which underlies the mould would, after their deposition, on account of their great power of absorbing moisture, naturally retard the action of worms for many ages. I have no doubt that worms, or their seed capsules, were transported across the plains by floods in the great rivers, and some probably lodged in the fine silt or sand often deposited on the edges of the streams, leaving them to effect a footing at many places. Some of the best land in the Colony is found on parts of the Plains. The plantations and fences now planted will in a few years serve to break the wind in the more exposed parts affected by the dry north-west gales, and naturally assist the actions of earth-worms. It is well known that some of the heaviest yields of grain are grown in New Zealand, and no one who has examined a heavy crop of wheat growing in this country could fail to observe the astonishing height and thickness of the stalks. This applies to land broken up and in crop for the first time. Mr. Darwin has said that archæologists in England “ought to be grateful” to earth-worms for the preservation of many antiquities of the Roman period. In New Zealand, naturalists are indebted to them for the preservation of many valuable bones of the moa and other extinct birds, and for ethnological relics, buried beneath their castings.

Although earth-worms are “lowly organized” forms of life, any time given to observing their habits is well spent, and only by patient observation can their fertilizing actions on the land be realized.

Note.—Since the foregoing was written, the great drought of the past season has broken up, and been succeeded by the greatest rainfall recorded in New Zealand in a short space of time, and destructive floods, equalled only by those in the memorable year 1868. To show, however, the disastrous effects of droughts on earth-worms, when followed by heavy rains and floods, I will add a few facts which will tend to strengthen my theory of accounting for the death of large numbers of worms. From the 10th to the 24th of July, rain fell sufficient to moisten the land to the depth of 2 inches, but no worms were observed moving on the surface during this time. At Christchurch, heavy rains fell almost continuously from July 28th to August 11th, and the Canterbury Times of August 13th had the following note on worms:—

“An extraordinary number of worms were observed on August 9th, in the side-channels in Gloucester Street. The little creatures, who had evidently been washed out of the earth at various points, seemed to have called meetings of the homeless poor at various points along the road. Just below the

– 139 –

Public School, there must have been a barrow-load of wrigglers in a heap—a large and excited meeting. Further on, by Latimer Square, there was a more thinly-attended meeting, at which those present seemed to have given it up as a bad job, and decided to take no action.”

At Oamaru, heavy rains fell from 10th August to the 22nd. During the afternoon of the 17th, the rain abated for several hours. Large numbers of weakly and apparently healthy worms were then observed moving in all directions on the surface, while some parts of the fields and public roads were literally strewn with the dead bodies of others; but all were of the three smaller species which inhabit open lands. The intestines of nearly all I examined were quite empty. A few only contained minute quantities of clay, which showed that they had burrowed into the clayey subsoil. At the end of the month many of the lakes and pools formed by the heavy rains had subsided. The bottoms of some were covered thickly with the dead bodies of earth-worms in a putrifying state. The drift weeds clinging to wire fences and gorse hedges through which the floods had passed also contained numbers of dead worms. On the hills and downs where they rose to surface they were instantly swept down the slopes, or scoured out of the earth by the numerous small streams formed by the heavy and incessant rains. The weather during the whole period being exceedingly mild, I think their deaths were not in any way accelerated by cold, although vast numbers of both weakly and healthy worms perished by drowning.

I am not sufficiently versed in the anatomy of earth-worms to discuss the subject fully; but I think that, were a number of them collected under the circumstances I have described, and forwarded to some specialist to report on them, it would doubtless settle the question, and explain the cause of their death. Although severe droughts or excessive moisture may generate disease among some species of worms, I am of opinion that more perish from exhaustion during droughts, or from the effects of it, than any other known cause. At Dunedin and other parts of Otago the rainfall for the month of August varied from 16·12 inches to 19·52 inches, and the destruction of worms during the same period was prodigious. These facts are of great interest in illustrating the effects of extremes in seasons on the actions and mortality of earth-worms.

Art. XIII.—A Description of the curiously-deformed Bill of a Huia, (Heteralocha acutirostris, Gould), an endemic New Zealand Bird.

[Read before the Hawke's Bay Philosophical Institute, 9th August. 1886.]

Plate IX.

A short time ago I received from a kind correspondent, a settler dwelling in the interior forest-land, the head of a Huia in a fair state of preservation, which he had then recently obtained from a Maori. This head is that of a female bird; the upper mandible of its bill being greatly and strangely deformed. From about 1 inch, or one-fourth of the normal length of the upper mandible from its base, it suddenly rises and remains at an angle of 45°, forming a regular ascending and suberect spiral of two large and equal curves, each being of ¾-inch open interior diameter; not unlike a gigantic corkscrew, and reminding one of the horn of the Strepsiceros. (See Plate IX.)

The total length of this deformed mandible, following the curves, is just 6 inches; its breadth at the widest part about the middle is 4 lines, which part is also flat above, and is devoid of nostrils; and its end or tip is sharply pointed, and vertical upwards; throughout its whole length it is much thicker, rounded, and very obtuse on the right side or edge, while the left edge is thin and sharp; the lower thin marginal base of the right edge of the mandible is also much produced and sharp, evidently larger than ordinary, arising from, I think, not having been worn away in use; while the corresponding opposite edge is much worn, being almost the only part of the upper mandible that could possibly be brought into serviceable contact with the lower mandible; its colour, too, is not that sure ivory-white of the healthy and normal bill, but more like that of common whitish horn.

The lower mandible is 2 ¾ inches long, being very much shorter and not so much curved as this portion of the bird's bill is in the normal state. The tip, too, is much more blunt, and is slightly worn or broken; on the left edge near the base is a tolerably large, worn depression or notch, where the upper mandible must have closed upon it in the efforts of the bird on receiving its food.

There is not the least indication of the upper mandible ever having been broken or bruised, and afterwards, in healing and using, grown out of its common natural form, and thenceforward assuming its present shape. The inference, therefore, is

– 141 –

that this bird must have been hatched with this peculiarly aberrant upper mandible; and, while we may reasonably suppose the parent birds assiduously fed it for some considerable time beyond the usual period of their young remaining unfledged, still, how it afterwards could have managed to exist and grow up seems truly wonderful! Especially when we consider the usual native food of the Huia, which consists of the larvæ of some of our largest beetles, (e.g., Prionoplus reticularis,) obtained by the bird industriously pecking and probing rotten logs and wood, much after the manner of the common Woodpecker. Besides, from its very strange configuration, it appears to have been far worse than merely useless, for it must have been always an obstacle in the way, and the means of keeping the bird's mouth always open.

From the general appearance, as well as from the extreme length, of this upper mandible, I should infer the bird to have been an aged one; for, according to Dr. Buller, the length of the bill of the female bird is from 4 to 4 ½ inches; but this upper distorted and unused mandible is no less than 6 inches long, while the lower one, which should correspond as to length, is only 2 ¾ inches! So, here we have two patent facts: 1, that the upper amorphous mandible grew continually, without being worn away through use; and, 2, that the lower one, having extra and constant work to perform, was consequently worn down and made defective far beyond its normal state and its natural power of growth-producing horn.

I have said that this head had belonged to a female bird: this is known by the greater length of the bill of the female bird, which is also narrower and much more curved than that of the male. For, while the bill of the female ordinarily measures about 4 ¼ inches, that of the male is only 2 ¼ inches, and is much more stout and strong, more wedge-shaped, and, consequently, less curved. Indeed, so great is the difference existing between the male and female birds in the form and length of their bills, that formerly, and for some considerable time, owing to their rarity and the scarcity of good specimens, the two birds were by our first ornithologists at Home believed to constitute two distinct species, and were consequently published as such.

I have already remarked that it seems almost a mystery how a bird with such a strangely deformed and all but useless bill could have managed to obtain its native food, so as to subsist and grow. We may, however, obtain a little light on this somewhat dark subject from an interesting paper on the Huia, written by Dr. Buller some 15 years ago for the Wellington branch of this Institute, and published in the third volume of their “Transactions;” Dr. Buller having had the peculiar and almost unique advantage of observing for more

– 142 –

than a year the habits of these birds while living in confinement; and from his pleasing paper I shall quote a few passages bearing more particularly on this part of my subject.

In the beginning of his paper, Dr. Buller observes:—“Their peculiar habits of feeding, which I have described from actual observation, furnish to my own mind a sufficient ‘reason’ for the different development of the mandibles in the two sexes, and may, I think, be accepted as a satisfactory solution of the problem. In the summer of 1864 I succeeded in getting a pair of live birds. I kept these birds for more than a year; and when the male bird was accidentally killed, the other, manifesting the utmost distress, pined for her mate and died ten days afterwards.”

“The readiness with which these birds adapted themselves to a condition of captivity was remarkable. Within a few days after their capture they had become perfectly tame, and did not appear to feel in any degree the restraint of confinement; for, although the window of the apartment in which they were kept was thrown open and replaced by thin wire netting, I never saw them make any attempt to regain their liberty.”

“They were fully adult birds, and were caught in the following simple manner. The Maori who had caught them attracted the birds, by an imitation of their cry, to the place where he lay concealed; then, with the aid of a long rod, he slipped a running knot over the head of the female and secured her. The male, emboldened by the loss of his mate, suffered himself to be easily caught in the same manner. On receiving these birds, I set them free in a well-lined and properly—ventilated room, measuring about 6 feet by 8 feet. After feeding freely on the huhu grub, a pot of which the Maori had brought with them, they retired to one of the perches I had set up for them, and cuddled together for the night.”

“It was amusing to note their treatment of the huhu. This grub, the larva of a large nocturnal beetle (Prionoplus reticularis), which constitutes their principal food, infests all decayed timber, attaining at maturity the size of a man's little finger. Like all grubs of its kind, it is furnished with a hard head and horny mandibles. On offering one of these to the Huia, he would seize it in the middle, and, at once transferring it to his perch and placing one foot firmly on it, he would tear off the hard parts, then, throwing the grub upwards to secure it lengthwise in his bill, would swallow it whole. … I sent to the woods for a small branched tree, and placed it in the centre of the room: it was most interesting to watch these graceful birds hopping from branch to branch, displaying themselves in a variety of natural attitudes, and then meeting to caress each other with their ivory bills, uttering at the same time a low affectionate twitter.”

– 143 –

“But what interested me most of all was the manner in which the birds assisted each other in their search for food, because it appeared to explain the use, in the economy of nature, of the differently formed bills in the two sexes. To divert the birds, I introduced a log of decayed wood infested with the huhu grub. They at once attacked it, carefully probing the softer parts with their bills, and then vigorously assailing them, scooping out the decayed wood till the larva or pupa was visible, when it was carefully drawn from its cell, treated in the way described above, and then swallowed. The very different development of the mandibles in the two sexes enabled them to perform separate offices. The male always attacked the more decayed portions of the wood, chiselling out his prey after the manner of some Woodpeckers, while the female probed with her long pliant bill the other cells, where the hardness of the surrounding parts resisted the chisel of her mate. Sometimes I observed the male remove the decayed portion without being able to reach the grub, when the female would at once come to his aid, and accomplish with her long slender bill what he had failed to do. I noticed, however, that the female always appropriated to her own use the morsels thus obtained. For some days they refused to eat anything but huhu, but by degrees they yielded to a change of food, and at length would eat cooked potatoe and raw meat minced up into small pieces.”

Dr. Buller also goes on to say that “Dr. Dieffenbach, in forwarding his specimens of the Huia to Mr. Gould in 1836,” [error, lege, 1839–41] “wrote:— ‘These fine birds can only be obtained with the help of a Native, who calls them with a shrill and long-continued whistle, resembling the sound of the Native name of the species. After an extensive journey in the hilly forest in search of them, I had at last the pleasure of seeing four alight on the lower branches of the trees near which the Native accompanying me stood. They came quick as lightning, descending from branch to branch, spreading out the tail and throwing up the wings.” (l.c.). From Dr. Dieffenbach seeing four on that occasion, I have little doubt of their being two pairs.

Moreover, and in further confirmation of much of the foregoing, I may briefly add what have at various times in past years, while travelling, come casually under my own notice respecting this bird. In some year in the decade of 1850 (I forget the exact one), I was, as usual, returning on foot from my annual journey to Wellington by the coast line, when one morning early, on the beach by the side of a small stream near Cape Turakirae (the west head of Palliser Bay), I suddenly came upon a single Maori, who had just then taken six of these birds, three males and three females; some were dead, killed in the capturing, and some were still alive. He told me that he

– 144 –

had seen them there on the low-stunted karaka trees (Corynocarpus lœvigata) the day before; and so, having prepared his materials, had returned thither early that morning, and had succeeded in taking them.* I am, however, not certain (now) that he had captured all. I might have bought them from him for a small sum, but I was too far away from my home in Hawke's Bay, with a long and heavy journey before me, and had no means at hand for preserving their skins. At that time (before, and for many years after), there lived at Mataikona, near Castle Point, a very curious eccentric old Maori chief named Pipimoho—a true type of the skilled old Maori tohunga, or knowing-man! Pipimoho was the only one in these parts who knew how and where to capture these birds; and this for a long time was his annual occupation, once or twice in the year to go to the inland forests from the East Coast, (to Puketoi and its neighbourhood), to snare the Huia; and this was done to supply the principal chiefs of Hawke's Bay—Puhara, Te Hapuku, and Hineipaketia, his superiors in rank. This quaint old man only died about three years ago. From him I have received many a curious and interesting relation, always wishing I had more spare time at command to obtain more.

I have also seen this bird in captivity with the Maoris, kept in a large light cage of network for the sake of its tail-feathers (rectrices), which were plucked as they arrived at maturity; the Maoris fed them with cooked potatoes, and other similar soft vegetable food.

Dr. Buller, in the same paper, also mentions, and gives the figure of, a larger and more highly curved form of the bill of the female bird than is usually met with. (Loc. cit., tab. iii., fig. 3.)

Further, I may also briefly state that, among the Parrots, the Maori Kaka, (Nestor meridionalis, Gml.), which I have formerly seen kept in confinement by the Maoris, I have noticed a few with very deformed upper mandibles; those birds had been kept by them for several years, and were aged, and being fed only (and sparingly!) on soft vegetable food, generally cooked potatoes, their bills, from want of their regular natural attrition on the harder substances of the forest, became overgrown and deformed. Indeed, the poor prisoners had not the common chance allowed them of biting and tearing their perch, or any wood (and this from mere thoughtlessness and carelessness, or long-continued custom, on the part of their Maori owners), for they were invariably kept fastened by a bone ring or carved

[Footnote] * The finding of those birds here, far away from the forests and close to the sea-beach, is opposed to Dr. Buller's statement as to their narrow restricted mountain-forest habitat. (loc. cit., p. 24.)

Curiously Deformed Bill of Huia.

circlet around one leg, and thus tied securely, but loosely, with a strong short cord to a slender polished cylindrical hard-wood spear, up and down which, for the space of 2 or 3 feet, the poor bird ran and danced and flapped his wings, always without water, and frequently in the hot burning sun, without any shade. These birds, however, were of great use to their owners for decoying other parrots for food, which through their means were often at set seasons slaughtered in large numbers.

Now, from all those interesting facts and observations relative to the habits and economy of the Huia, we may, I think, gather:—1. That these birds are quiet and social. 2. That they keep together in sexual pairs, and are therefore likely to be monogamous. 3. That the cock and hen are greatly attached to each other. 4. That they naturally and mutually help in their search after their own proper food. 5. That they can and do, without difficulty, make a thorough change in their diet or food, from animal to vegetable substances. And so, I think, we may reasonably conclude that the unfortunate female bird, to whom belonged this unnaturally distorted and almost useless upper mandible of her bill, was helped throughout a long life by her kind and attentive mate.

Hab. In trees, totara timber (Podocarpus totara, A. Cunn.), forests, Norsewood, County of Waipawa; 1885.

Obs. This is a very remarkable species, from the comparative shortness of its body and great length of its stout posterior pair of legs, which are nearly four times the length of its body and head! being considerably longer than those of the two very large species—H. gigantea, Col.,* and Deinacrida heteracantha, White.dagger Unfortunately, my only specimen is imperfect, wanting the upper part of the head, antennæ, maxillæ, and prosternum; it got crushed in capturing by the workmen at the sawmill, and I only obtained the major part of the insect (that had been preserved for me) a few days after. Luckily, however, the legs and body were perfect, and so was a portion of the head, containing the clypeus, labrum, and maxillary and labial palpi. It must certainly be a rare species, as none of the workmen at the mill, nor of the villagers, (who subsequently saw it), long-used as they have been to forest work, had seen one like it before, although they very well knew the commoner and smaller kinds: it was also quite unique to me.

I may here repeat what I remarked before, in describing another rare and allied species, Deinacrida armiger, Col., that this insect appears to possess characters belonging to those two closely allied genera (Deinacrida and Hemideina), and that I doubt those two genera being naturally distinct.

account of some young lizards (4), that were brought forth in my house, two of which I succeeded in rearing. At that time, however, I knew nothing of the manner of their being brought forth or expelled by their parent (as I have pretty fully related in that paper); and now, having very recently gleaned a few more particulars respecting the same, which may prove both interesting and curious, and perhaps unique, I propose to bring the same before you in this paper.

Early in this year, 1886, I received from Mr. J. Stewart, of Takapau (a member of this Society), a fine specimen of our green lizard, in good condition and very lively. I suspected at the time it was a female, and probably pregnant. Mr. Stewart informed me that it had been very recently captured—viz., on the 29th December, 1885. It was some time, however, before I could get it to eat, although I supplied it with flies, much as I did my former ones. In time it ate them, but sparingly; and although I often watched it, I never once detected it doing so, or seeking to capture them! in this respect so very different to those I formerly had. Yet it ate them, that was certain, without leaving a wing or a leg, for they were not to be found in its house (or glass case), out of which they could not possibly get; and the fæces of the reptile further proved it. It also differed widely from my former ones in not drinking; for, although I often tried to induce it to drink, it never once took any water, while the others were frequently lapping water, and licking wet spots on leaves, etc.; and I did not keep any water with this lizard in its house. It would, however, swim very well and strongly when I put it into a large basin of water. As the weather became colder in this present autumn—in May—it ceased taking any flies, and I had supposed it was about to hibernate, as the others did; so I set it aside, but kept looking at it occasionally. The last time that I did so, on the 8th of June, it seemed much as usual, only thinner from its long fasting, and not torpid, but rather lively. I therefore gave it a couple of flies, which, however, it would not eat. On my looking at it again on the following day, the 9th of June, I found that it had given birth to two young ones—curious-looking little things and fully formed, but both dead. The following is a description of them:—

They were both nearly alike, in size, shape, appearance, colour and weight; each one distinct, lying separate in the case, and closely enwrapped in its own proper semi-transparent chorion or secundine, which was entire around one, and slightly broken about the snout of the other below its eyes, so that the front part of its little head appeared. Each was closely doubled up—one with its tail coiled tightly around its snout, and the other with its tail bent round and downwards beneath its chin; their shape was broadly oblong, one end much rounded, and

– 149 –

the other (containing the head) more produced; measuring, the one 8, and the other 9 lines in length, and 5 lines in width, compressed, with the surfaces smooth and flattened, but somewhat uneven owing to the prominencés of the limbs, etc., and bearing a general resemblance to the smaller seed of the common garden bean (Faba vulgaris). Each fetus weighed 15 grains, their colour darkish-green on the back, shaded off in spots to lighter green and almost to white in some of the little knobs and slight hollows; the eyes bright and yellow, with dark pupils, as in the adult. The chorion, or enveloping membrane, was excessively thin and white, and filled with minute capillary branching flexuous veins of a bright florid red colour, a few of the main ones being tolerably large, presenting a pleasing appearance. The fetus that had its enwrapment broken at its snout, had its mouth slightly open, showing the little notch in the tip of its tongue. From their very fresh, damp, and glistening appearance, they appeared to have been very recently expelled.

From these circumstances here related, three facts in the history of these little animals seem to be established:—1. That their young are brought forth alive, and not within an egg (as is the case with many of the Saurians); this I had formerly supposed (loc. cit., p. 264); 2. That their time of gestation must be at least 5 ½ months; 3. That they bring forth two at a birth—this, also, I had before observed (l.c., pp. 251 and 264).

A brief description of this adult lizard may also be here given, seeing it varies a little from the species described. Extreme length 6 ½ inches, of which the tail is 3 ½ inches; colour a uniform bright green above, (which is particularly vivid on casting its old skin or epidermis), inclining to darkish-green as it grows older, and much paler beneath; head rather small, slightly concave between the eyes, and scales flattish; tongue darkish plum-coloured; two large blunt semi-transverse scales on the side of the base of the tail near the vent, and three similar ones on the opposite side; a patch of pre-anal pores singly on larger scales in 4–5 short rows; toes slender, long; tail cylindrical, very slender, much elongated, its scales not imbricated.

In some of its characters this lizard resembles N. grayii, Bell,* especially in the shape of its head with flattened scales, the few large convex scales near the base of the tail, (which, however, in that species are said to be “four on each side,”) elongated toes, and uniform green colour. It has, also, a few characters in common with the species described by me—N. pentagonalis (loc. cit.)—as in its pre-anal scales with pores, elongated toes, and the colour of its tongue; still it seems different in other characters, and has certainly shown widely

[Footnote] * “Trans. N.Z. Inst.,” vol. iii., pp. 7 and 8.

– 150 –

different habits. It agrees still less with the other described species of green Naultini. It may be a variety of N. grayii, Bell, but certainly not of N. punctatus, Gray, which species Professor Hutton has subsequently stated to be identical with N. grayii.*

Addendum.—Since writing the above, and very recently, I have received a letter from Mr. D. P. Balfour, of Glenross, a member of this Society, dated 16th July, 1886, informing me of a green lizard, a species of Naultinus, and believed by him to be of the same species as N. pentagonalis, Col., which he had in confinement, having produced two young ones on the 14th of July. One of them was born alive, and the other dead, and then only after some considerable difficulty, Mr. Balfour largely assisting the mother; for when he saw her on this occasion, this second young one was half expelled, tail foremost, the other having been first born. Mr. Balfour also says that the living one measured 3 inches at its birth.

This is the third known instance of the birth of these green lizards, and all of them happened about mid-winter, (a strange season !) when they should be in their natural semi-torpid hibernating state. This additional circumstance, now confirmed, seems very peculiar, and is worthy of being noted. The living young lizard, mentioned by Mr Balfour, seems to be of an extraordinary large size, “3 inches long when born:” those four born here with me, in 1878, were only a little over 1 inch in length when first seen, (loc. cit., p. 263), and those described in this paper (although still uncoiled in their fetal membranes), cannot be much more.

Art. XVI.Remarks on Palinurus lalandii, M. Edw., and P. edwardsii, Hutton.

[Read before the Otago Institute, 10th August, 1886.]

Plate X.

In Miers's “Catalogue of the Stalk- and Sessile-eyed Crustacea of New Zealand,” two species of Palinurus are assigned to this country—one, P. lalandii, M. Edw., identical with a species found in Cape Colony; and the other, P. edwardsii, Hutton,

[Footnote] * “Trans. N.Z. Inst.,” vol. iv., p. 171.

[Footnote] †. See “Trans. N.Z. Inst.,” vol. xii., p. 251, for the first.

– 151 –

peculiar to New Zealand. In his account of the latter form, Miers remarks: “The specimens from New Zealand, in the collection of the British Museum, that have been referred to P. lalandii, belong to this species [P. edwardsii]; and hence I am in doubt whether P. lalandii be also an inhabitant of the New Zealand seas. It was formerly considered a common New Zealand species.”

This remark, and the fact that I constantly found myself unable to distinguish the supposed two species from one another by the diagnostic characters given by Hutton and by Miers, induced me to make a special study of the question, and to this end I have obtained a series of specimens of the undoubted P. lalandii from the Cape of Good Hope. For these, I have to thank Mr. R. Trimen, F.L.S., Curator of the South African Museum, Cape Town, who kindly sent me more than a dozen examples belonging to both sexes, and of very various sizes. With these I have carefully compared about an equal number of Palinuri from the Dunedin market, as well as Hutton's type specimens in the Otago University Museum, of which one is labelled P. lalandii, and two P. edwardsii.

The diagnostic characters of P. edwardsii relied on by Hutton are best given in his own words: “This species differs from P. lalandii in its much smaller size, in the shape of the beak, in having no spine on the penultimate joint of the anterior legs, and in having a small spine at the distal extremity of the third joint of the last four pairs of legs.”*

a. Size.—In this respect there is a perfect gradation between the largest and the smallest crayfishes brought to the Dunedin market.

b. Characters of the rostrum.—The rostrum of P. lalandii is thus described by Miers: “Rostrum with the lateral spines smooth above and below, and not projecting nearly so far as the small median spine, below the base of which are two small spines.” That of P. edwardsii is described in the same words, both by Miers and by Hutton: “Beak small, compressed, curved upwards, and with two small spines at its base.” From this it would appear that it is the compression and the upward curvature of the rostrum of P. edwardsii which distinguishes it from that of P. lalandii, since the two small basal spines are common to both species.

As I have elsewhere pointed out,dagger the above description of the rostrum is wanting in exactness. The two small spines at its base have nothing to do with the rostrum proper, being given off from what I have called the “clasping processes” (figs. 7–11, cl.p1), pedate structures arising from the præstomial plate,

[Footnote] * “Trans. N.Z. Inst.,” vol. vii. (1874), p. 279.

[Footnote] † “Trans. N.Z. Inst.,” vol. xvi. (1883), p. 298.

– 152 –

(= epimeral plate, Huxley = the area to which the eye-stalks are attached), and ascending one on each side of the rostrum (r), to the base of which they are closely applied, although quite free from it. Each clasping process consists of a forwardly-directed or anterior limb (cl.p1), and of an upwardly-directed or dorsal limb (cl.p1). The anterior limb usually terminates in a true spine—i.e., is sharp, of a brownish-yellow colour, and horny appearance: more rarely it is pointed, but devoid of a true spine, and occasionally it terminates bluntly. The dorsal limb is sometimes blunt Fig. 9, sometimes bi-lobed Fig. 10, sometimes sharp Fig. 11, and occasionally terminates in a true spine. The rostrum itself may be nearly horizontal Fig. 7, 10, or slightly upturned Fig. 11, or strongly upturned Fig. 9, and usually terminates in a true spine. All these variations are found both in the South African and in the New Zealand specimens, and are therefore in no way diagnostic, but mere matters of individual variation.

c. Propoditic spine of anterior leg.—The presence or absence of this spine is a mere question of age. It is present in all the larger specimens, both from the Cape and New Zealand, absent or rudimentary in the smaller examples.

d. Meropoditic spines of legs 2–5.—The dorsal surface of the distal extremity of the meropodite, or third segment, of one of the four posterior legs of a New Zealand crayfish, is shown in Fig. 12 The segment is seen to present a somewhat crescentic elevation (cr), at its distal end, and proximad of this to be produced into a longitudinal ridge (l.r), which projects distalwards over the crescentic elevation, ending in a sharp spine (sp. 1): This is the spine acknowledged by Hutton and Miers to be common to the two species under discussion. The horns of the crescentic elevation, which are directed forwards, are sometimes both blunt Fig. 12, sometimes each terminates in a spine Fig. 14, while sometimes the anterior only Fig. 13 and sometimes the posterior only is spinose. It is the presence of one, the anterior, of these small spines (sp. 2,) which is held to be diagnostic of P. edwardsii, in which species, therefore, the formula of the meropoditic spines is considered to be i.I.o., while in P. lalandii it is said to be o.I.o. I find, on the contrary, that the presence or absence of these small lateral spines is a matter of individual variation, the formulæ o.I.o., i.I.o., i.I.i. occurring both in African and in New Zealand specimens, and sometimes in the different legs of the same specimen.

One cannot but conclude, therefore, that, putting aside P. tumidus, Kirk,* which I have not examined, there is but one species of Palinurus hitherto discovered in New Zealand; and the question next arises, should this be called P. lalandii or

[Footnote] * “Trans. N.Z. Inst.,” vol. xii, p. 313.

Palinurus.

– 153 –

P. edwardsii; or, in other words, the diagnostic characters hitherto relied upon having broken down, are there sufficient differences from the Cape species to entitle it to retain a distinct specific name?

After a careful comparison, by means of drawings and measurements, of the series of New Zealand and African specimens, I find that there is one constant and reliable difference between the individuals from the two localities: It consists in the greater complication of the sculpturing or tuberculation of the abdominal segments in the Cape form.

The difference to which I refer will be apparent from a comparison of Fig. 1 and Fig. 2, which represent the first and third abdominal segments of a New Zealand specimen, with Fig. 3 and Fig. 4, which show the corresponding somites of a Cape specimen of about the same size.

In both cases, the first segment is marked by a strong transverse groove (g), which divides it into a larger anterior and a smaller posterior portion, the former being covered by the carapace in the extended condition of the abdomen. In all the Cape specimens which have come under my notice the segment in question shows a double row of tubercles (Fig. 3, t) anterior to the groove; while in New Zealand specimens the anterior section of the somite is either wholly devoid of tubercles Fig. 5, or presents one or two very small detached ones Fig. 1. Further, in the Cape crayfishes, the posterior section of the same segment bears two rows of flattened squamiform tubercles; while in the New Zealand form there is only a single row of imperfectly-formed tubercles.

Similar differences are found in the remaining abdominal segments, which show the same separation into anterior and posterior areas, the groove Fig. 2 and Fig. 4 being, however, less clearly marked than in the first. In the Cape specimens Fig. 4 the tubercles on the anterior division are very numerous, only a small portion of the segment being without sculpturing; in New Zealand specimens Fig. 2 and Fig. 6, there are only two or three rows, so that fully half the tergum is left bare. In the posterior area of the 2nd–5th segments there is a close agreement with the corresponding region in the first, the Cape specimens Fig. 4 having about two rows of tubercles; the New Zealand specimens Fig. 2 and Fig. 6, a single row of imperfectly-formed tubercles.

The figures show at a glance the practical identity in these respects between the two supposed New Zealand species, (“P. lalandii,” Fig. 1 and Fig. 2; P. edwardsii, Fig. 5 and Fig. 6 and the marked difference of both from the true P. lalandii, Fig. 3 and Fig. 4, from the Cape.

The carapace in the South African specimens is usually broader in proportion to its length than in New Zealand

– 154 –

examples, the proportion of length to breadth being from 100–72 to 100–65 in the former, 100–65 to 100–60.5 in the latter. The pleura of the abdominal segments, measured from the hinge (Fig. 1 and Fig. 2, h) to the terminal spine, are also, as a rule, proportionately shorter in the African than in the New Zealand specimens. But in both these characters the examination of a large series of individuals shows a complete gradation between those from the two localities.

The Cape specimens were not in a sufficiently good state of preservation to allow of a careful examination of the internal organs. But I find that there is no difference of any importance from the New Zealand form in the gills, the gastric skeleton, the mouth parts, or the microscopic structure of the branchial setæ.

In the sculpturing of the abdomen, on the other hand, the examination of about a dozen specimens of all sizes and both sexes from each locality has shown no intermediate stages.

I conclude, therefore, that there are constant though slight differences between the common New Zealand Palinurus and P. lalandii from the Cape of Good Hope, and that Hutton's name, P. edwardsii, should be retained for the New Zealand species, P. lalandii being no longer considered as an inhabitant of our coasts.

The differences relied upon are, however, so small, that but for the wide separation of the two localities one would hardly consider them as of more than varietal importance. Mr. Trimen informs me that P. lalandii “is confined to the western (Atlantic) shores of the Cape, and does not occur even in False Bay, immediately east of the Cape of Good Hope itself,” and it would certainly be a remarkable fact to find the identical species reappear so far east as New Zealand. Haswell* states, however, that P. edwardsii occurs both in Tasmania and St. Paul's Island, two localities which help to bridge over the distance between South Africa and New Zealand, and it is quite possible that specimens from these places may be found to furnish intermediate steps, and thus to necessitate the merging of P. edwardsii in P. lalandii.

In any case, the existence of a single species, or group of closely-allied geographical sub-species, in South Africa, St. Paul's, Tasmania, and New Zealand, is a strong argument in favour of Hutton's theory of an antarctic continent, from which the great Southern land-masses were stocked.

Art. XVII.—On a new Species of Giant Cuttlefish, stranded at Cape Campbell, June 30th, 1886 (Architeuthis Kirkii).

[Read before the Wellington Philosophical Society, 19th July, 1886.]

Cape Campbell and the adjacent coasts seem to be places of favourite resort for these great Cephalopods during the winter months, a year seldom passing without one or more of them being cast on shore, usually during the months of June and July. The greater number, however, of these, owing to the attacks of sharks, dogfish, and porpoises, are stranded in such a mutilated condition as to be of little value to the naturalist; but I am quite satisfied, from the examination of a number of imperfect and of two perfect specimens, that they are all Decapods. None of the Octopods which have come under my notice have a solid heavy body like the Decapods, and they all seem when cast on shore to be able to return to the water

– 156 –

without difficulty. This a Decapod is unable to do; both the perfect specimens of the latter obtained by me at this place were, when first observed, alive and uninjured, and, though close to the sea, the one on a shingle beach and the other on smooth papa rock, neither was able to return to its native element. Mr. T. W. Kirk, in a paper read before this Society, October 10th, 1879, mentions an Octopus stranded at Kaimarama, in Hawke's Bay, but I am greatly disposed to believe it to have been a Decapod which had lost its tentacular arms.

About ten years ago I obtained a fine Decapod on shore in Clifford Bay, Cape Campbell, having a body 7 feet long, and a total length of 20 feet, a large and powerful creature, but not nearly so formidable a monster as that which I now desire to bring under your notice. As it lay upon the rocks it presented from a distance the appearance of a mass of raw beef, or of having been covered with dried blood. On a closer inspection this was found to be owing to a great number of minute specks of a bright red-brown colour with which the epidermis was covered. Under this the flesh was firm and white, presenting the appearance of blanc mange made from corn-flour. The body was slender, cylindrical, the sides nearly straight, having a small caudal fin, or fins, for they did not extend quite to the end of the tail or unite across the body, and were mere lateral expansions of the mantle. The outer edges of these fins, if produced so as to meet, would have formed a perfect oval. The head was short and thick, with large eyes furnished with a lid, the mouth being armed with a large and powerful beak. The eight sessile arms were of equal length, 6 feet 6 inches, but not of equal thickness, though all were thick and strong; two, those next the tentacular arms, were much stouter than the other six, being as large at the base as an average man's leg eight inches above the knee. All the sessile arms were furnished with stalked suckers, having a row of incurved teeth, and varying in size from those at the base, with a diameter of 1 ½ inches to that of a small pea at the point. The tentacular arms were long and slender, almost exactly similar to those of Architeuthis verrilli, as figured by Mr. T. W. Kirk.* They had also the same arrangement of small tubercles and suckers, at intervals of 2 feet from the club to the base. The club, as will best be seen from inspection of the specimen forwarded, differed from that of A. verrilli chiefly in having small suckers on very long stalks placed along the margins between the large ones. The internal shell was lanceolate, rather broad, transparent, and brittle when first taken from the body. It was in several pieces, owing probably to its having been broken during the animal's struggles to regain the water.

[Footnote] * “Trans. N.Z. Inst.,” vol. xiv., p. 36.

– 157 –

This Decapod is not similar to any which I have previously met with, or of which I have seen descriptions; it differs chiefly in the shape of the caudal fin, in the large size of two of the sessile arms, in the arrangement of the suckers on the clubs, and in the unusual size of the beak, which, with the tongue, etc., is forwarded with the club. As it is probably a new species, provisionally I venture to dedicate it to Mr. T. W. Kirk, who has done so much good work in describing our Cephalopods.

The following measurements were taken:—

Ft. in.
Body, from anterior margin of mantle to end of tail 8 3
Head, from margin of mantle to base of arms 1 9
Sessile arms 6 6
Tentacular arms 18 10
Extreme length 28 10

It is to be regretted that a swiftly incoming tide prevented me from obtaining the greatest circumference, which must have been about 8 feet, or the number of suckers on the sessile arms, which I estimate at over 50.

Art. XVIII.—On the Anatomy of the Limpet (Patinella radians, Quoy).

[Read before the Philosophical Institute of Canterbury, 7th October, 1886.]

Plate XI.

The following paper is an attempt to compare the structure of the New Zealand Limpet (Patinella radians) with that of the European Patella vulgata, L., as described in Cuvier's “Memoires,” page 15.

Patinella was made a genus by Professor Dall. The genus was founded upon Patinella magellanica (Gmelin), but that definition has been slightly extended, and made to include all the Patellas of New Zealand.*

It will be seen that the most important differences (as they will be shown in their proper places), between Patinella radians and Patella vulgata are—

1. That in Patinella radians the branchiæ do not extend all the way round the head, as they do in Patella vulgata, but

[Footnote] * “Proceedings of the Linnean Society of New South Wales, 1884,” p. 374.

– 158 –

end at the sides of the head, in about a straight line with the disc of the mouth.

2. The convolutions of the intestine are somewhat different to those shown by Cuvier, Fig. 12; but I have not been able to distinguish any expanded part of the intestine representing the stomach, further than that containing the coils of the odontophore.

3. The nervous system in Patella vulgata consists of a large ganglion, as shown in Cuvier, Fig. 16, from which nervefibres go off to all parts of the body. In Patinella radians it will be shown that there are three separate ganglia, connected to one another by thick commissures. There are the pedal ganglia, consisting of two thick masses on the upper surface of the foot. There are two parieto-splanchnic ganglia connected by a commissure going over the back, and by two other commissures connecting them with the pedal ganglia. These ganglia give off nerves to the somatic cavity, mantle, and branchiæ. The cerebral ganglia are situated in the head, and are connected with the parieto-splanchnic ganglia by commissures, and there are small ganglia on their course where the nerves go out to the tentacles. This nervous system shows that our southern species (as most southern forms are) is a more primary and older form than the northern species. This, I think, is the distinguishing characteristic of Patinella radians.

The shell is ovate and moderately convex; the apex is situated about a third of the length of the shell from the anterior end. The ribs in it are small, slightly rounded, and radiate out from the apex to the margin of the shell. They are intersected round the margin with short ribs extending only about half-way up the shell. The ribs are of a dark-brown colour, and the interspaces are of an ash colour. In the interior of the shell, the upper part, above the circular muscle, is of a dark-brown colour; below the circular muscle it has a nacreous appearance, having small grooves corresponding to the ribs on the outside, which at the margin are slightly flattened out, giving the rim of the shell a slightly serrated appearance.

The head consists of a large fleshy mass (shown in Fig. 2, a, b,) slightly narrowed at the neck; at the sides of the head are two well-marked tentacles, thick at their bases and tapering towards the points, very much of the shape of horns (x, y, Fig. 3). I have not been able to recognise the eyes, at the bases referred to by Woodward, page 278. The mouth opens on the lower surface of the body (it is shown, c, Fig. 1), it is simply a large oval-shaped sucking-disc.

The foot is a large olive-coloured oval disc, covering the lower surface of the body; by means of this muscular foot, the animal attaches itself to rocks; the free edge of the mantle hangs down round it.

– 159 –

The odontophore is armed with four tooth-like processes arranged in a series. Those of the inner series are of a brown horny colour at the apex, and transparent round the base.

The odontophore is about four times the length of the body of the animal, it is shown in position, (d, e, Fig. 2), after removing the foot. The teeth in the body of the coil are much sharper than those near the mouth, showing that they are replaced from behind as fast as they are worn out by friction in triturating the food. The muscular system round the odontophore is shown in Fig. 2

The branchiæ are numerous lamellar processes like ampullæ, lying between the fringe of the mantle and the foot; they do not extend all the way round the edge of the mantle, but only up to the sides of the neck; in Patella vulgata, figured by Cuvier, they extend round the whole body.

Nervous System.—As the nervous system seems to be the distinguishing feature between Patinella radians and Patella vulgata, I have dissected it out with great care. In P. vulgata the nervous system is simply a ganglionic ring, giving out nervefibres to the whole body. But in P. radians there are three different pairs of ganglia: (1.) Pedal ganglia are two ganglionic masses on the surface of the foot, connected together by a short thick commissure (ab, Fig. 5); they are connected to the parietosplanchnic ganglia by two very short commissures (ca, and bd, Fig. 5), and to the cerebral ganglia by two long commissures (ae, and bf, Fig. 5). These pedal ganglia give off two nerve-fibres to the surface of the foot (ah, and bh, Fig. 5), nearly meeting at their posterior ends. (2.) The parieto-splanchnic are not so large as the pedal ganglia; they are situated outside of and above the pedal, and connected to them by short commissures, to one another by a long commissure passing round the neck (cd, Fig. 5), and to the cerebral ganglia by two commissures (df, and ce, Fig. 5). These ganglia give off nerves (m, m, Fig. 5), to the mantle, and nerves (k, k', Fig. 5), to the sides of the somatic cavity, and the nerve g, Fig. 5, to the visceral cavity. (3.) The cerebral ganglia are situated in the top of the head at e,f, Fig. 5; they give off nerves to the tentacles, and one going round the top of the head (erf, Fig. 5).

Reproductive Organs.—There is a large ovary shown in Fig. 2 (lm), but I have not been able to trace the openings to the surface. I noticed that this ovary is much larger in summer time.

Muscular System.—The chief muscular organ is the foot; it covers the whole of the lower surface of the body, and acts like a sucker, attaching the animal to a rock. The circular muscle attaches the mantle to the upper rim of the foot. Its position is shown in Fig. 2 (pq). From this muscle the mantle hangs free round the foot. The muscles surrounding the head, and

– 160 –

working the odontophore, are shown in Fig. 2 (ab); they end in two globular-ended rods.

Alimentary System.—The mouth is situated on the lower surface at the anterior end of the body; it is simply an oval-shaped sucking-disc, and has a serrated appearance. It opens into a large œsophagus, surrounded by strong muscles; in it lies the odontophore with its three coils lying on the left side of the body when examined from below (shown Fig. 2, de). I have not been able to distinguish clearly an enlarged part, representing the stomach. The intestine has a great number of coils. I have traced them all out; they are shown in Fig. 4 (a to b). The coils differ from those in the European P. vulgata. The rectum is slightly swollen, and the anus opens on the left side of the head, under the mantle (shown k, Fig. 3, and b, Fig. 4). The liver is very large, occupying nearly the whole of the body cavity; it covers the whole of the intestines (shown Fig. 2, xy, and Fig. 3, fg).

I have not been able to make out the salivary glands referred to by Professor Ray Lankester in the “Annals of Natural History.”

Art. XIX.—On the Mollusca of the Vicinity of Auckland.

[Read before the Auckland Institute, 20th September, 1886.]

Some years ago, I prepared a catalogue of the Mollusca of Auckland Harbour, which was printed in vol. viii. of the “Transactions of the N.Z. Institute.”* Although as complete as the materials at my command would permit, it contained many faults, both of omission and commission. I now propose to correct these mistakes: to give a complete list of the species observed in the harbour, with notes on their habitats, etc.; and to add thereto a similar catalogue of the land and fresh water species inhabiting the Auckland Isthmus and its vicinity. I am in hopes that the paper may be useful in two ways. First, in giving to the local collector a catalogue of the species which can be obtained near Auckland, together with some information as to where to look for them. Secondly, as a contribution to a knowledge of the distribution within the Colony of the New Zealand Mollusca, a matter which it is important should be worked out, for it will give some assistance in solving many questions connected with the geology and physical history of the country.

For the purposes of this paper, I shall consider Auckland Harbour to extend in a northerly direction as far as Lake Takapuna and Rangitoto Reef; and to the eastwards, to the Tamaki-Heads and Motutapu Island. Its western boundary would be formed by a line drawn from Kauri Point to the mouth of the Whau River. By the term Auckland Isthmus and its vicinity, I mean not only the isthmus proper, extending from the Whau portage to Penrose, but also that portion of the North Shore to the south of a line drawn from the head of Lucas' Creek to a point on the sea-coast a little to the north of Lake Takapuna. The whole district would have a greatest length of about ten miles, with a greatest breadth of nine. The land area is probably over 60 square miles.

In my previous paper I have given a sketch of the chief physical features of the harbour, and some general remarks on the local distribution of the Mollusca found therein. It would be useless repeating this here; more especially as in the appended catalogue I have attempted to give some information as to the special localities and relative frequency of each species.

[Footnote] *“Trans. N.Z. Inst.,” vol. viii., art. xxxvii.

– 162 –

The total number of species observed in the district is 242. Of these, 37 are land Mollusca; 12 fluviatile; and the remaining 193 marine. They fall in the following classes:—Cephalopoda, 3; Gastropoda, 177; Lamellibranchiata, 61; Brachiopoda, 1. Further search will probably add materially to the number of land-shells, for they have not been collected with the same care as the other families. Our land Mollusca are so small and inconspicuous, and so many of the species closely resemble one another, that it is no easy matter to exhaust a small district like the Auckland Isthmus. I do not anticipate that any additions of numerical importance will be made to the marine or fluviatile species, although discoveries will doubtless be made from time to time.

If the necessary material had been collected, it would have been interesting to have compared the molluscan fauna of the Auckland District with that of similar areas in other portions of the Colony, and to have worked out some general results as to the range of the species. But this cannot be done at present. Wellington is the only other locality for which a tolerably complete list has been prepared, and even there the marine species are alone catalogued. When carefully compiled lists have been published for at least a dozen stations on the coast line of both Islands, then the distribution of our Mollusca will be better understood, and some advance may be made towards determining the range and relative frequency of the species.

Art.. XX.—The Land Mollusca of the Thames Goldfields.

[Read before the Auckland Institute, 14th November, 1886.]

It will surprise many of those who spend a large part of their lives in the forests of New Zealand to learn that there are a great number of land-shells in the bush. These shells, however, are in general so small and so inconspicuous that they are only found after a careful search, although every forest has, perhaps, thousands of at least forty different species. They are not only overlooked on account of their small size, but they hide also under leaves, or under the bark or in the crevices of the trees.

A few of the larger ones are, of course, well known in the localities where they are numerous—such as Paryphanta busbyi, and Rhytida greenwoodii—but the greater number range in size from that of a pea to a pin's head. Indeed, one of them, and not the smallest, has a Latin cognomen that means “pin's head.” There are at present known to science about one hundred and twenty of the Land Mollusca of New Zealand, and these have been classified and described by Captain Hutton in a paper in the sixteenth volume of the “Transactions.”*

It occurred to me, when collecting land-shells for him and for my friend Mr. Cheeseman, that it might be useful to make a list of the species found in the Thames District, and to mention at the same time the most favourable localities for searching for them. In one respect the land-shells are deserving of more than a passing attention, and that is the surprise that every one must experience in finding them at all in New Zealand.

They are easily drowned in fresh water, and salt water is sudden death to them. They cannot bear exposure, as they quickly disappear from even rude clearings; and yet our land-shells have their nearest relations in Tahiti, Samoa, and the Solomon Islands. Countless ages must have elapsed while such slowly-moving animals gradually spread over the intervening space between such distant countries. Indeed, their great antiquity is confirmed by the fact of finding fossil land-shells on a fossil tree in the Palæozoic rocks. It may be supposed that, when forests flourished on the oldest sedimentary rocks of New Zealand, the ancestors of the present land-shells swarmed under the dead leaves and on the tree trunks.

[Footnote] * “Trans. N.Z. Inst.,” vol. xvi., art. viii.

– 178 –

One vast forest extended, perhaps, from New Zealand to Queensland on the west, and to Tahiti on the east. It may be significant that this very ancient form of fauna is abundant on the nikau (Areca sapida), and on the kiekie (Freycinetia banksii), both of which belong to the most ancient forms of flora. The nikau is a favourite for land-shells in any situation, but they are found more numerously on it in deep shady valleys near the banks of streams. The shells usually found are Carthæa kivi, Patula buccinella, P. corniculum, Phrixgnathus maria, Amphidoxa chiron, and Thalassia neozelanica. A couple of years ago, after an unsuccessful search for land-shells on the main range of this peninsula, I cut down a nikau (Areca sapida), and by examining each leaf right into the heart I found twelve different species, chiefly of the genera Patula, Phrixgnathus, and Psyra.

The kiekie (Freycinetia banksii) usually contains the same kinds of land-shells as those found on the nikau; but, as a rule, the less number of nikaus in the locality, the greater number and greater variety of shells the kiekie affords. There is a species of Phrixgnathus, mentioned in the list appended, that appears peculiar to this tree.

The tree-fern is another very ancient type of flora, and here also a successful search for land-shells can be made; but they are easily overlooked in the brown scales and decaying fronds, except such conspicuous shells as Patula corniculum.

I have made a special trial of how many kinds of land-shells can be gathered in and about the black tree-fern (Cyathea medullaris), and the silver tree-fern (Cyathea dealbata) that formed a grove, and there were found 19 different species. Of these, 6 were species of Patula, 3 of Phrixgnathus, 2 of Endodonta, 2 of Therasia, 1 Elæa, 1 Amphidoxa, 1 Fruticicola and Thalassia neozelanica.

The land-shell last mentioned is the commonest found in the bush. It is generally the first to meet the eye when the day's search begins. This search is of course delayed until the real bush track is entered on, that leads through the groves of pukapuka (Brachyglottis repanda) that usually form the outskirts of the forest.

The large leaves accumulate in hollows, or near the roots of the mahoe (Melicytus ramiflorus), or the pukatea (Atherosperma novæ-zealandiæ), or the taua (Beelshmeidia taua), and these piles of damp decaying leaves become a favourite haunt for Rhytida greenwoodi, Thalassia neozelanica, and Phrixgnathus maria. Many other shells are also frequently found, but they are usually dead ones.

On advancing further, or rather climbing higher into the bush, a place must be sought on the slope of a ridge, where small stones are covered with black mould and decaying leaves; and, by patient search, small live land-shells will be found,

– 179 –

such as Psyra planulata, Phrixgnathus erigone, Patula buccinella, Therasia celinde, and Amphidoxa chiron.

The handsome hairy shell, Thalassia portia, is very local, and though four or five may be found in one place, the vicinity may be searched in vain for any more.

Many land-shells are found under the bark of dead trees, especially in damp places. The rimu (Dacrydium cupressinum) is best for several kinds of Patula, and under the loose bark of the taua (Beelschmeidia taua), Phrixgnathus conella, Elæa jeffreysiana and Endodonta pœcilosticta are not uncommon.

On cushions of moss growing on dead trees, or on patches of Hymenophyllum, Endodonta leimonias can be found, but this minute shell is very inconspicuous.

The fleshy tubers of Earina autumnalis may harbour Otoconcha dimidiata; but this shell is more likely to be found under the outer decaying fronds of the nikau (Areca sapida) in damp situations.

The eggs of land-shells are found chiefly under the fronds of the nikau, or within the leaves of kiekie or of Astelia solandri. That the land mollusca and their eggs have many enemies, appears evident to me, but to write on this subject would require much closer observation than I have been able to devote to it.

Freshwater Mollusca.

The freshwater mollusca are represented in every stream and in every swamp, and though very plentiful, there are very few species. In the Kaueranga River, about half a mile from its mouth, there is an abundance of a Mytilus which resembles M. ater, but it may be a new species. In the upper course, Melanopsis bifasciata is not uncommon on pieces of dead wood, and some tributary rivulets abound in Potamopyrgus corolla.

Planorbis corinna, and Pisidium neozelanica, appear to occur in only one place, but they are both inconspicuous and easily overlooked. The one is found on Azolla rubra, and the other on the muddy bottom at the roots of Cyperus ustulatus. I append a list of the Mollusca found in the district, which may probably be increased by the addition of a few more species.

Art.. XXI.—Description of the Little Barrier or Hauturu Island, the Birds which inhabit it, and the Locality as a Protection to them.

[Read before the Auckland Institute, 14th November, 1886.]

Having heard the practical and beneficial proposals to science and agriculture made by Judge Fenton at the last meeting of this Institute, I thought it might be useful to give a brief and general description of Hauturu Island, which I have visited five times, spending in all about ten months, searching and cutting tracks in various directions. Hauturu Island is situated 12 miles in a north-easterly direction from Rodney Point. The island is, in a straight line from north to south, 4 ¼ miles, from east to west 3 ½ miles, in extent, and rises about 2,383 feet above sea-level. It is very broken, except on the south-eastern portion, where there is a small flat, and a few slopes grown over with grass, ferns, and small ti-tree; these places were cleared by cutting firewood. A main range runs across the island from west to east, which in places is very narrow and steep. The Island is well timbered, and there are some very fine kauris in the interior.

– 182 –

The general bush consists of—

Manuka Rewarewa Rata
Puriri Nikau Taridi
Tawa Maire Punga
Rimu Miro Pohutukawa

The Pohutukawa about Christmas-time gives this island the appearance of a large rose garden, when these trees are covered with their red blossoms, on which the honey-eaters delight themselves from early morn till late in the evening, climbing about from one blossom to another to suck the honey. The korimoko may also sometimes be seen chasing a tui, making various evolutions in the air, and, on returning, making the place ring with their powerful whistle. On the heights are numerous shrubs similar to the vegetation on the New Zealand Alps. Some of the gullies are very dense with creepers, such as supplejack, “lawyers,” and a large variety of ferns and moss. There are several creeks: four have their outflow north, one northeast, two south, three west. There are some minor ones, but in summer most of them get dry, except one north, one south, and one west, which always have water, especially the one in the centre of the island. There are some large and deep water-holes, and in some places the creeks are narrow. The mountains are nearly perpendicular and of various shapes and forms, some bare, others grown over with low vegetation; the scenery is wild, but very romantic: some places are so broken that I was obliged to use a rope for pulling up and letting down my provisions and dog. In one locality, I could not find a place to camp without the risk of rolling over the cliffs, and had to tie myself to a tree. The formation is mostly conglomerate, and dark rock similar to basalt.

Having described the island, I will now bring before you the advantages Hauturu Island possesses over others for protecting and preserving the birds. Firstly, there are only three landing-places; two are known to the coasting vessels: one on the south-western side, where the Maori settlement is, the other is half-a-mile west, where I had my camp; but even these places have boulder shores, and the landing is dangerous, as a heavy surf rolls in constantly, except when the weather is north or north-east and there is no swell on. On the south-western side, on top of the hill, one can overlook both landing-places. Here the land is not so broken, and could be cultivated. The third landing-place, a boulder beach on the eastern portion of the island, is very rough. I had a boat smashed into fragments by the surf at this place. There is no fresh water near it in summer. One good man, who took a delight in his duty, could act as overseer on the whole island.

– 183 –

The high slopes would be a favourable resort for kakapo (Stringops), crow (Glaucopis), saddle-back (Creadion), New Zealand titmouse (Orthonyx ochrocephala), creeper, and Certhiparus novæ-zealandiæ. The lower ridges would be suitable for kiwi (Apteryx), the deep gullies for wrens (Xenicus), thrushes (Turnagra), robins (Petroica), etc. The above-mentioned localities are well suited for all the specimens named, by my own observations in various places. Appended is a list of the birds which inhabit Hauturu Island, viz.:— Hieracidea ferox
Circus gouldi
Athene novæ-zealandiæ
Halcyon vagans
Pogonornis cincta
Prosthemadera novæ-zealandiæ
Anthornis melanura
Zosterops lateralis
Acanthisitta chloris
Orthonyx albicilla
Gerygone flaviventris
Petroica toi-toi
P. longipes
Anthus novæ-zealandiæ
Rhipidura flabellifera
Creadion carunculatus
Platycercus novæ-zealandiæ
P. auriceps
P. alpinus
Nestor meridionalis
Eudynamis taitensis
Chrysococcyx lucidus
Carpophaga novæ-zealandiæ
Apteryx mantelli
Hæmatopus unicolor
Larus dominicanus
L. scopulinus
Sterna frontalis
Puffinus gavius
P. assimilis
P. tristis
Procellaria cookii
P. parkinsoni
P. gouldi
Prion turtur
Haladroma urinatrix
Dysporus serrator
Phalacrocorax brevirostris
P. varius
Eudyptula minor.

The following are foreign birds which have migrated to Hauturu Island:— Coturnix pectoralis
Turnix varius
Passer domesticus
Fringilla chloris
Turdus merula
T. musicus.

The Natives assured me that these last-named birds were not brought there.

The above list of 40 different specimens of New Zealand birds will show that the locality is more favourable than the mainland. There also exist several specimens which are nearly extinct, or very rare, on the mainland. I agree with Judge Fenton that bees are destructive to birds, from my personal observations—viz., to the honey-eaters (Nectarinea) and Psittacidæ, which breed in hollow trees. Honey-eaters are deprived of their food by the bees at a time when they most need it—when they have young—and, being insectivorous, they catch the bees and

– 184 –

sometimes get stung and die. Furthermore, the bees occupy the breeding resorts of Psittacidæ. Settlers and Natives told me they found kaka eggs, and young parakeets, in the honey-comb of wild bees on the mainland.

On Hauturu Island there are no bees: the chief, Tenetahi, would not allow them to be landed, as he wished to protect the birds. There is one drawback—viz., wild pigs and cats, which are very destructive. The former root all the ground-birds out, and devour them; the latter watch night and day for their prey. But these two pests a good marksman with well-trained dogs could soon put a stop to. If the members of this Institute are in favour of obtaining Hauturu Island for preserving and protecting the Native birds, from my knowledge, and after many years studying the habits of New Zealand birds, I could not recommend a more favourable place. It would be of great benefit to science and agriculture to have such a means of preventing the extinction of these remarkable birds, which, as they multiplied, could easily be transferred to the mainland for the purpose of checking the insect pests; and if my aid in the project is of any use, I will be most happy to procure (gratis) live specimens of both sexes of Apteryx (kiwi) and Stringops (kakapo), if the Committee will provide me with cages and arrange for the transport, before or when I am again on the West Coast, about December next. The insectivorous birds and honey-eaters could be fed during transport on mashed potatoes, and common biscuits soaked in water, with sugar, and a few meal-worms or ant-eggs. As I expect to be away on another expedition, I have asked Professor Thomas if he would kindly read this paper for me; and if members wish to ask any questions in reference to these observations, I will be most happy to reply.

The above is written from my personal observations and facts.

[Read before the Auckland Institute, 18th October, 1886.]

Petroica toi-toi—Pie-tit (Miro-miro).

This beautiful little bird is a native of the North Island, but on the mainland is becoming scarce. I found a few pairs in the Tangahuia Ranges in 1879, in the Tokatea and Waitakerei Banges in 1880, and in Pirongia, Rangitoto and Mokau Ranges in 1882. They are more plentiful, however, on certain islands

– 185 –

in the Hauraki Gulf. When I visited Morotiri Island in 1880, and also Taranga Island in 1888, they were rather rare. On Hauturu Island, in October, 1880, I found this bird very common, but on my second trip in 1882 they seemed to have diminished.

The sexes differ considerably in plumage: the male bird has upper part black, a white spot on the top of the bill, a white, bar across the wings; throat, breast, and abdomen white: the female, upper part greyish-brown, white spot on top of the bill, yellowish-white bar on the wings, and greyish-white on the throat, breast, and abdomen. The young birds are spotted. The pair build the nest together, of moss, spider-webs, and rotten wood, lining the inside with the down of seeds taken from the various flowers. The nest is always flattened in the fork of a tree. I never found it more than 8 or 10 feet above the ground, and in very thick scrub. The female lays in October from 3 to 4 eggs, and male and female breed and rear the young together twice a year. In the beginning of December the young birds are full-grown, and the parents leave them. On Hauturu Island, in 1880, I found a nest containing two white-brownish speckled eggs. About the end of December, 1882, I found a nest with 4 eggs, near our whare. In 14 days the young birds came out of the shells. Every morning and evening, while the female was sitting, the male came and serenaded her. The song consists of six notes, as “ti, oly, oly, ho,” which he always repeats twice. One male came several successive mornings near my whare, I threw him some bread crumbs, which he picked up; a week after he brought a female and three young ones, feeding them in front of the whare. After a time the male got so bold that he actually came to the door and called for food. They stayed about the whare till I left it. Through its boldness, I think, this bird is becoming scarce. They prefer clearings, where they hop about on low branches with the wings slightly drooped, the tail always erect, and uttering a sweet whistle of one note, as “see;” the male sometimes five notes. The female is of a most retiring disposition, and is not so often seen as the male. Their food consists of insects and larvæ. On the morning of the 10th December, 1883, (after a severe thunderstorm and rain in the night), I went up the ranges, and in a very thick gully I heard a twitter; on approaching, 1 perceived a pair of Petroica toi-toi hopping about very excitedly; after watching them for a time, I went closer and looked into the nest, where I saw three eggs covered with water. On my taking away the nest, the birds did not show any anxiety for their loss. They are very useful in destroying insects, with which the New Zealand forests swarm. I often saw them carrying insects over an inch long to their nests.

– 186 –

Petroica Longipes, Less.—Wood Robin (Tototowai).

This species is confined to the North Island, where it was formerly plentiful, but is now only to be found in a few localities, and is very rare, and will soon become extinct like so many other New Zealand birds. Dr. Buller told me that he could not get a pair even at a high price.

On the north-western slope of Hauturu Island, in October, 1880, I shot one female. In November, 1882, I went to the centre of the island, where I saw several pairs. It prefers secluded gullies, near creeks, and hops about on the ground or in low scrub. The male sings very early in the morning, and late in the evening. Only on one occasion have I observed this bird singing on the top of a high tree, which it did for a quarter of an hour. The song is very sweet and powerful, and, when undisturbed, the bird is very tame. When I was digging out various specimens of Procellaria, this robin always came round and picked up the worms and other insects from under my hoe. On one occasion, when I was sitting on a stump watching a long-tailed cuckoo devouring a large weta, with my gun across my knees, one of these robins came and perched on the barrel. Often when at lunch, one or a pair came and picked up the crumbs at my feet. If I threw a piece of biscuit or meat, it was taken away a short distance and eaten, and the recipient returned for more. At the commencement of the breeding season, which begins in October, the female lays from 3 to 4 eggs; each pair occupies a certain limit, and if interfered with by others, the weaker is obliged to retreat. Their food consists of insects and their larvæ. I never met this bird on my southern expeditions, and the only pair on the mainland were those I saw on the Tohua Ranges. Early in December, 1883, during my stay on Hauturu Island, the Natives found a nest with four young birds (Petroica longipes), but when I reached the spot the birds had flown. The nest, which had evidently but recently been disturbed, was built of moss, grass, etc., and in the niche of a tree. This bird reminds me very much, in its movements and habits, of the European robin (Rubicula sylvestris), and I felt it an act of vandalism to shoot some for specimens. They are very useful birds, and deserve every protection.

Anthornis Melanura.—Bell-bird (Korimako).

This bird is very common in the South Island of New Zealand, also on several small islands on the east coast. At Whangarei Heads, in the North Island, I saw one specimen which was blown in a gale from Morotiri Island, and was in such a state of exhaustion that it could hardly move, and died in a few moments. On skinning, I found it very thin, the crop being quite empty. I searched all the northern forests from

– 187 –

the Mokau to the Bay of Islands, and across from one coast to the other, but never again observed it. I attribute its disappearance to cats, rats, bees, and bush-fires. The first time I saw this bird in the South Island was in the forests on Banks Peninsula, in 1877, and again in the same year on my trip to the west coast, where I found it common. In the North Island I could not discover it on the mainland, but on visiting Morotiri Island, April, 1880; Hauturu Island, October, 1880; and Taranga Island in November, 1880, I found them plentiful. In December, 1880, on my second visit to Morotiri Island, I found that the birds had materially decreased in number. On my second trip to Hauturu Island in October, 1882, at the centre of the island, I found the bird at home, morning and evening. I had a concert near my nikau whare, from 10 to 20 birds of both sexes sitting on the trees and singing in chorus together. The morning and evening song differs from that during the day, the morning and evening notes consisting of three distinct sounds resembling the chimes of bells, from which I suppose the bird derived its name. The song during the day is more of a warbling sound. One gives the signal to begin, with a snap of the bill, and all the birds join in the chime, keeping perfect time together until the leader, with another snap, gives the signal for a rest. After a few minutes rest, the chiming song is repeated.

In September, male and female begin to build the nest, of small branches and moss, lined with feathers, in thick branches of trees from 20 to 50 feet above the ground; and I have also found nests in hollow trees. In October the female lays from 4 to 5 white eggs with light-red spots, which they hatch together, and both parents feed the young brood. When leaving the nest, the male looks after his family till they are able to take care of themselves. At the approach of danger I have seen a male knocking a young bird from a branch when it would not listen to his call.

This bird is very bold and tame; it lives on insects, berries, and honey from trees and flowers, especially the flax blossoms (Phormium tenax), which in some places grows in great abundance, and has a quantity of honey in the calyx, into which the Bell-bird inserts his bushy tongue to suck out the honey. On the Little Barrier, on the 10th December, 1883, I found three nests under a bunch of tussock (a parasite growing on a tree), completely sheltered from wind and rain, 20 feet above the ground. In each nest there were 4 birds; I took one nest, to ascertain if the bird could be kept in confinement. After having them in my care for several days, during which I fed them on soaked biscuit mixed with honey, and cooked potatoes, they got on well; but, through the carelessness of my assistant, they escaped.

– 188 –

I made a stay at the West Coast Sounds in the South Island, in 1884, where the Bell-bird is not so common, the specimens which I procured in Dusky Sound being considerably larger, darker, and softer in plumage than those of the North Island. Male and female differ in size and plumage, the latter being smaller and duller. I feel sorry that these birds have also disappeared, in some localities, as they brighten the melancholy stillness of New Zealand forests by their powerful song, and are very useful in destroying numerous insects.

Art. XXIII.—Ornithological Notes.

[Read before the Auckland Institute, 20th September, 1886.]

Creadion carunculatus.—Saddleback (Tieke).

This bird derives its popular name from a peculiarity in the distribution of its two strangely contrasted colours, uniform black, back and shoulders ferruginous, the shoulders of the wings forming a saddle. In structure it resembles the starling (Sturnidæ); it has also the wedge bill. In December, 1877, on my expedition in the South Island, I found this bird on the chain of high ranges along the left bank of the Teremakau River, but it was rather scarce. I have seen it frequently near Lake Brunner and on Greenstone Hill, also on Mount Alexander, and in April, 1879, on Mount Alcidus, Rakaia Fork.

During my researches in the North Island, in 1880, I found this bird on Hauturu Island, but rare, and again in October, 1882, when I went to the centre of the island, but it was still scarcer. On my visit to Taranga Island, in November, 1880, I was greatly pleased to find the saddleback in abundance; and on a later trip, in February, 1883, it was still more numerous. On my first trip, in 1880, to this island, I found a saddleback's nest about 10 feet from the ground in a manuka tree; this nest was made of moss, twigs, and fine grass, with one white brownish-spotted egg in it. In February, 1883, on exploring in a north-easterly direction, I heard a peculiar whistle, which differed from that of any other New Zealand bird. On going closer I perceived five birds, and, concealing myself, in order to watch them, to my surprise I saw male, female, and three young Creadion carunculatus. The female was feeding the young birds, which had just left the nest. I first shot the parents; the young, which had never moved from the branch, I gave to Dr. Buller, F.R.S., with a description, and

– 189 –

he read a paper before the Philosophical Society, Wellington. After this, I procured several specimens of adult and young birds, which had the same plumage as the old birds, black and ferruginous, only a little duller; their wattles are either invisible or very small. I measured the wattles of adult males, and found them half-an-inch long, and of a deep orange colour; those of the female are smaller, and of a citron hue.

Strange to say, in the South Island I only saw this bird on the higher ranges, where it prefers steep thickly-wooded gullies, but on Taranga Island, in the North, I found them everywhere, both on the ranges and near the seashore, especially on the flax blossom, from which they suck the honey. I also observed it on the Great Barrier in June, 1882, and on Rangitoto Ranges in the King country in March, 1882.

The female lays from two to three eggs in November; male and female hatch and rear their young together. The saddleback is a very noisy bird. The whistle consists of three and four notes—the first three, like “vi, zi, o,” he repeats twice, and then the four notes in succession, like “te, te, te, te.” In the breeding season, when the female is hatching, the male generally sits near her on a branch, singing. The notes are not so harsh as the former ones. If this bird observes anything unusual, he hops in a very excited manner, with the wings close to the body, head bent downward, and stopping and listening at intervals, through the trees to examine the object. When satisfied, he flutters to a distance, the flight being very feeble, as the wings are very short. They are very active in climbing, hopping from one branch to another, picking in decayed wood, or crevices in the bark, in a similar manner to the woodpecker, searching for insects and their larvæ, of which they destroy a number, thus being useful. They also feed on berries and honey. During all this time they keep up a continual whistling.

Curious to say, during five years' observation, in which I have procured a series of specimens of Creadion carunculatus, adult and young in all stages, I never noticed any difference in plumage; they were always black, with a ferruginous saddle.

This bird is very rare on the mainland in the North Island. On dissecting their crops, I found insects and minute seeds.

Creadion Cinereus, Buller.—Saddleback (Tieke).

This bird is distinct from Creadion carunculatus; the body is smaller, the bill longer and thicker, the tail also is longer, and the plumage different. Its colour is a uniform olive-brown, the wings and tail darker, with a reddish tint on the upper and lower tail-coverts. The wattles are smaller, about a quarter of an inch long, and of light yellow colour. I first saw this bird in December 1877, at Greenstone Hill, near Lake Brunner, and subsequently in February, 1878, at Mount Alexandra.

– 190 –

I have observed them in pairs, along with the yellow-head (Orthonyx ochrocephala), and with Creadion carunculatus, also the brown creeper (Certhiparus novæ-zealandiæ), hopping about from branch to branch in search of food. I shot a series of specimens of Creadion cinereus, and on skinning them I found the reproductive organs of both sexes well-developed. On my return to Christchurch, when speaking of this variety or species, I was told that this is the young of Creadion carunculatus. When I pointed out the difference in size and plumage, I was informed that the plumage would become the same, in the third year, as that of Creadion carunculatus—i.e., a uniform black, with back and shoulders ferruginous. Being at this time a new arrival in the colony, I did not contradict my informant; I corresponded with Dr. Buller, who agreed with me that Creadion cinereus is a distinct species from C. carunculatus. But determined to find out the truth, I followed up the subject until February 7th, 1883, and on my trip to Taranga Island my efforts were crowned with success, for I observed the first pair feed their young, which I gave to Dr. Buller to enable him to bring forward his lost species, on which he read a paper to the Wellington Philosophical Society. After that, I procured a few more specimens of Creadion carunculatus, feeding their young, which were just out of the nest, the plumage being exactly like that of the parents, only a little duller, uniform black and ferruginous on the back and shoulders; the wattles are either invisible or very small. I have observed a series of Creadion carunculatus in all stages, and never saw any difference in their plumage.

Through all the northern forests, I have never met with Creadion cinereus. In 1884, during my researches on the West Coast Sounds, I saw Creadion cinereus up the ranges, in low scrub, male and female together in pairs. I shot one pair in Dusky Sound, in June 1884, a second pair in August of the same year, and a third pair in Milford Sound in October 1884. I never observed in any of the Creadion cinereus which I shot at different seasons the slightest difference in plumage. Their food consists of insects, their larvæ, and small berries, which I have found in their crops when dissecting. I only found this bird in the South Island, and even there they are scarce near settled districts. I have met them frequently on the West Coast in uninhabited places. The whistle of Creadion cinereus consists first of three notes, “te, a, r,” which he repeats several times, then four, like “te, te, te, te.” Their movements are quick in hopping and climbing, but feeble in flying; they prefer thickly-wooded and steep gullies.

Glaucopis wilsoni, Gray.—Crow (Kokako).

This remarkable bird, the natives told me, was once common on all the ranges of the North Island forests, but now it only

– 191 –

frequents the higher ranges, away from habitations, where it appears at the end of April and stays till September. It is confined to the North Island. Early in the morning, and in the evening, the traveller will hear some very sweet notes, like a flute. The call of the male and female is alike, consisting of two notes, like “vio,” but the song of the male bird is different, and composed of five pleasing notes, like “vio, ku, ku, ku,” which sound near, though the bird is generally a considerable distance off. They are very tame, but when they are much disturbed it is very difficult to detect them without a dog. When approached, they hide in the thick crowns of trees, peeping through the branches at intervals to see if the intruder has disappeared, in which case they begin to whistle. Should the bird be disturbed a second time, it hops away with marvellous swiftness through the branches, from one tree to another, so that it requires a very quick shot to procure it. The birds always go in pairs, male and female together; and if the call be imitated, they come hopping along, often so near that I could almost touch them. In October, they retreat to very thickly-wooded gullies, between the highest ranges, where they breed, and are seldom seen. The plumage is slate-colour, with a brownish tinge on the wings, back, and tail, a small black bar on top of the head, near the root of the bill; wattles blue in the adult, pink, and smaller, in the young bird. My belief is that they breed twice a year, and have two or three young at a time. Early in April, 1880, on the Tokatea Ranges, near Castlehill, I found in a tussock on a tree a nest with three young half-fledged birds, one of which I secured; the others escaped. The nest was built very carelessly of dry branches, ferns, and moss, and about 30 feet from the ground. In February, 1882, I shot two full-grown young birds in the Pirongia Ranges. I also observed this bird in September, 1879, in the Tangahuia Ranges; in 1880, in Maungataroto; near Ngunguru in 1882, and on the Great Barrier and Waitakerei Ranges. It is strange I never met with this bird on any of the islands off the east coast except the Great Barrier, where most of the New Zealand birds are more plentiful than on the mainland. This bird feeds on berries and the young leaves of various plants, which I have found in their crops. It uses its wings, which are short and small for its size, very seldom, and only to flutter down, but is very active and quick in climbing. In December, 1885, I observed three young birds sitting outside a nest, which was in the crown of a very thick miro, in the Waitakerei Ranges. They disappeared into the nest when I approached, and in a few days went away with their parents. In the pairing season, when not disturbed, the male makes various evolutions by drooping and spreading the wings, erecting the tail, with bent down head and outstretched neck, in a similar way to the

– 192 –

capercailzie (Tetrao urogallus), and whistles to the female, who sits still and seems to admire her companion's movements.

Their limits are growing narrower, owing to ravages of bushfires and of cats and rats.

Orthonyx albicilla.—White-head (Popokatea).

This bird is found in the North Island, in both the lower and higher ranges. The first pair I saw was on the Tokatea Ranges near Castlehill, in April, 1880; the second on Hauturu Island, where they are plentiful, in October, 1880. I shot a pair on the Pirongia Ranges in February, 1882, and about the end of April I saw another pair at the Mokau. I never saw this bird on the mainland north of Auckland. Mr. T. Cheeseman, F.L.S., told me that eight or ten years ago these birds were quite common about Auckland, but they have now completely disappeared. Strange to say, on my second trip to Hauturu Island, in 1883, I was agreeably surprised to find that since my visits in 1880 and 1882 the white-head had increased in numbers. Its movements are similar to those of the European cole titmouse (Parus major), hopping and climbing about, and sometimes hanging by the feet under the branch of a tree, picking into the bark for insects and small seeds. It is a lively inquisitive little bird, any noise in the bush attracts a flock of them, which come near with a shrill whistle, stopping a little while to see what it is, and then flying away again. It prefers certain localities, and there are always several pairs together. In December, 1882, I noticed that the same pairs came in the morning and evening near one of my whares, and they were so tame that I could observe them feeding their young from the door. The male and female build the nest (which is very neat) together, out of twigs, moss, and grass, and line it with feathers, from 8 to 16 feet above the ground, in very thick trees, manuka. At the end of October the female lays four eggs, of a pinkish colour, with light-brown spots. I have also found this bird's eggs in December, so they must breed twice a year. This they do together.

One evening, at the Little Barrier, hearing a noise, I cautiously approached, and from my concealment saw a morepork following a white-head, near a nest. The male immediately tried to divert and allure it away, which he succeeded in doing by hopping further and further, calling the whole time, and on being pursued darted into the thickest scrub, where it was impossible for his larger enemy to follow. I then lost sight of him, but, on going back, to my surprise I found he had already returned, and was hopping round the nest, on which the female was sitting on eggs, which I forwarded to Dr. Buller.

I found a few specimens of the white-head in the Rimutaka Ranges, near Wellington, in October, 1884. There are also some

Picture icon

– 193 –

on the Great Barrier Island, but none on the Hen and Chickens, or any other nearer islands. The females and young birds are duller in plumage than the adult males: Head, breast, and abdomen white, with a very slight brownish tinge; wings, back, and tail light-brown. Their call consists, first, of three notes, like “viu, viu, viu,” then four, like “zir, zir, zir, zir.” They are useful, as they destroy a number of insects, which I have found in their crops, with minute seeds. This bird resembles in structure, habits, and call, the Parus major. In my opinion a more suitable name for it would be the “New Zealand Titmous.”

Art. XXIV.—Notes on some Moa Remains found at the Great Barrier Island during February, 1886.

[Read before the Auckland Institute, 18th October, 1886.]

Plate XXII.

Before going to the Barrier, in August, 1885, I was told by Mr. G. A. Martin, of the Survey Department, that, when at the island in 1881, he had found some Moa bones close to the Owana River, and not far from the beach. So when we were camped near there at the beginning of the present year, I asked my party, who were in the habit of walking on the beach on Sundays, to look out for Moa bones, which they kindly did, Sunday after Sunday, but without success, until shortly before we left, when Mr. George Malcolm, who had been with Mr. Martin, succeeded in finding some bones, supposed to be those of the Moa. These I brought to town, and submitted to Mr. Cheeseman, who pronounced them to be Moa and Seal bones, which was so far satisfactory, as establishing the fact that Moa bones had for the first time—as I learn from Mr. Cheeseman—been found off the mainland.

These bones comprise—

  • 1 Femur,

  • 2 Tibiœ,

  • 1 Metatarsus.

  • A portion of a rib;

and belonged, I am informed by Mr. Cheeseman, to one of the smaller species; the leg bones measuring in all about 22 inches, so that the bird must have been about 4 feet in height.

They were found near the surface of the drift sand, about 30 yards distant inland from and 20 feet above high water-mark, spring tides, and almost directly opposite to the mouth of the Owana River, as shown on the plan (Plate XXII.), from which

– 194 –

it will be seen that the river, when within eight chains of the coast, turns almost at right angles and runs parallel with the coast for about 40 chains before joining the sea. On this narrow strip of land, which rises to a height of 330 feet above the sea, a most picturesque, and what must have been an almost impregnable, pa stands, having a perpendicular rock face towards the sea, and a very steep slope inland towards the river. From this fact, and the one that the only dry flat on the island is there, it is reasonable to suppose that it was a favourite camping-ground of the Natives, and that much feasting must at times have been indulged in. Therefore, I think we may conclude that these bones, associated as they were with those of the Seal, formed, with them, in all probability, the remains of a repast.

The most interesting question to decide is whether the bird was found on the island, or taken there, and it is one upon which I cannot venture to express an opinion; but, from the very precipitous, broken, and rocky nature of the island, coupled with the fact that it must, at the time of the Moa, have been almost entirely covered with dense forest, I am inclined to think that if it existed there at all, the Moa would have considerable difficulty in travelling, and would be compelled to come down on to the beaches for a “constitutional,” where it would easily be captured by a Moa-hunter.

In conclusion, I may mention that Mr. Malcolm, who found these bones, is of opinion that they are not as large as those found by Mr. Martin's party. If this is so, it is obvious that more than one Moa was eaten there; and should remains be found at different parts of the island, there will be some foundation for the belief that the bird existed there.

[Read before the Auckland Institute, 21st February, 1887.]

During my first visit to Auckland, I took the opportunity of collecting and examining large quantities of sand and mud along the shores of the Hauraki Gulf, which proved to be very rich in Foraminifera and other minute organisms. The material was taken at low water in creeks and pools, and on the sandy beaches, and washed in the ordinary simple way, by which a fairly pure residuum of Foraminifera, Diatoms, Crustaceans, Polyzoa, etc., was obtained.

After my return from the King Country, I hope to be able to devote some time to the study of the Rhizopoda, and to give a detailed description of the numerous varieties, with illustrations of the principal types, a list of synonyms, and tables of geological and geographical distribution. In this short paper, I merely intend to give a general idea of the rhizopodal fauna from the littoral zone, and a list of species or types. The slides containing the enumerated forms will be left at the Auckland Museum.

The general appearance of these washings remains very uniform. The characteristic features are the extraordinary abundance of the porcellaneous and some of the higher vitreous types, the scarcity of arenaceous and the lower vitreous forms. The Miliolidœ form over 90 per cent. of the whole fauna, as in various other shore-gatherings from the northern seas. The only new varieties belong, as far as I can judge, to this extensive group, but it is not unlikely that other forms new to science will be found after further researches, especially in the shallow creeks facing the open sea. With the exception of these varieties, all the species found near Auckland occur in the same cathymetrical zone of almost every latitude,

– 197 –

and in many tertiary and even older formations of Europe. The specimens are, as a rule, of good size, and even the most delicate tests remarkably well preserved. They can easily be picked out with an ordinary pocket-lens, and examined with a 1-inch objective.

In the porcellaneous group, the genus Miliolina is best represented, while the allied genera, Nubecularia, Biloculina, and Spiroloculina occur only in isolated individuals. Ribbed and otherwise ornamented species are exceedingly rare. The Miliolines are very variable, and run so gradually into each other that no distinct lines of demarcation can be drawn. Monstrous specimens are frequent, and difficult to determine.

The second large group is almost entirely absent. It is evidently in deeper water that we must look for arenaceous forms of the families Astrorhizidœ, Lituolidœ and Textularidœ. The most interesting species from these shores is Thurammina papillata, of which one of the slides contains two small spherical specimens.

The Lagenidœ, belonging to the third group (Hyalinea), are also exceedingly rare. The most beautiful, delicately ornamented, Lagena squamosa is the most abundant. The higher rotaline forms are well represented, and belong to geographically widely diffused types.

1. Gen. Nubecularia.

No good specimen, but small fragments of a variety of N. lucifuga, Defr.

2. Gen. Biloculina.

Rare specimens of B. ringens, Lam.

3. Gen. Miliolina.

With the typical forms, numerous abnormally developed shells were obtained, which can be considered as intermediate forms between the quinqualoculine and triloculine Miliolinœ and the symmetrical Biloculinœ and Spiroloculinœ, and the different dimorphous groups.

It is an easy task to construct long series which show almost every conceivable deviation with regard to general form, arrangement and relative size of chambers, shape and position of the aperture, and colour, which prove clearly how little value we have to attribute to morphological characters, which are often considered of greatest importance for the systematical arrangement of species, and even whole genera. Some specimens are almost symmetrical, others show different modes of growth at different ages. Frequently the final chamber does not follow the general plan of growth. A careful comparison of numerous specimens is necessary to ascertain the relationship between the widely different modifications of the simplest types.

– 198 –

Innumerable mutations of the following species are met with:—Miliolina circularis, Born.; M. seminulum, Lin.; M. oblonga, Mont.; M. labiosa, D'Orb.; M. secans, D'Orb.; M. bicornis, W. and T.; M. linnœana, D'Orb. To which we can add, as distinct varieties:—M. aucklandica and M. polymorpha.

4. Gen. Spiroloculina.

Small specimens, occupying an intermediate place between Miliolina (Quinqueloculina) and Spiroloculina.

5. Gen. Rhabdammina.

Fragments of monothalamous arenaceous tubes, belonging, probably, to a large species of the Astrorhizidœ group (var. of Rh. abyssorum?).

6. Gen. Reophax.

Irregular, dentaline modifications of R. scorpiurus, Mont., with dark grey, calcareous cement.

7. Gen. Haplophragmium.

Small, finely arenaceous, colourless, and ochreous forms of H. canariense, D'Orb., and H. globigeriniforme, P. and T., similar to those found in the North Atlantic and in some mesozoic strata (zone of Ammonites transversarius, etc.).

8. Gen. Thurammina.

Delicate, spherical tests of Th. papillata, Brady, with short papillæ distributed regularly all over the surface, resembling the passage forms of Th. albicans and Th. papillata from the upper jurassic strata.

9. Gen. Valvulina.

Finely arenaceous, much compressed specimens of V. conica, P. and T., almost isomorphous with Trochammina squamata.

10. Gen. Bolivina.

Very rare, delicate, glassy modifications of B. punctata, D'Orb.

11. Gen. Lagena.

Four species of the groups Lœvigatœ and Reticulatœ. The absence of the cosmopolitan L. globosa, L. lœvis, L. marginata, and L. sulcata, so common in British littoral deposits, is a curious fact.

12. Gen. Globigerina.

Small ash-grey specimens of G. bulloides, D'Orb.

13. Gen. Patellina.

Two young shells of P. corrugata, Will.

– 199 –

14. Gen. Discorbina.

This group is well represented along the whole coast, and numerous fine specimens were obtained, the largest near the pier of North Shore. When the surface is much worn, or the aperture filled up or damaged, it is difficult to distinguish them from the other rotaline forms with which they are always associated. The following species were recognized:—D. rosacea, D'Orb.; D. turbo, D'Orb.; D. globularis, D'Orb.; D. valvulata, D'Orb.; D. orbicularis, Terq.

15. Gen. Truncatulina.

A few doubtful specimens, probably of T. lobatula, were found at Cheltenham Beach.

16. Gen. Carpenteria?

A single fragment from the same locality appears to belong to this curious group.

17. Pulvinulina.

Fine large specimens of Pulv. repanda, F. and M., are frequently met with; also, P. elegans, D'Orb.

18. Gen. Rotalia.

Two distinct varieties, of very different size, of the common R. beccarii.

19. Nonionina.

Numerous beautiful tests of at least three species are found everywhere—N. depressula, W. and T.; N. scapha, F. and M.; N. asterisans, F. and M.?

20. Gen. Polystomella.

Several varieties of these beautifully-marked forms were obtained. They belong to P. striatopunctata, F. and M.; P. crispa, Lin.; P. macella, F. and M.

Art.. XXVII.—On the Occurrence of Junonia vellida and Deopeia pulchella in New Zealand.

[Read before the Wellington Philosophical Society, 18th February, 1887.]

Plate VIc.

During the present summer a new butterfly has appeared in the Wellington District, which I have every reason to believe has not previously been met with in New Zealand. On December 26th, while collecting on the sea-beach near Paremata, I noticed a large butterfly, which I at first thought was Vanessa cardui, but on capturing the insect was surprised to find it quite distinct. By careful searching I procured four more specimens, one of which I forwarded to Mr. Olliff, of Sydney, for identification, who has kindly informed me that it is Junonia vellida, a very common Australian insect. Since that time I have taken two more specimens at Wainuiomata, and the insect is very abundant at Paikakariki, where I saw a great number last week, but was unable to take any owing to their great timidity, and the rough nature of the ground.

I think there can be little doubt that this insect is a true native of New Zealand, which has been previously overlooked, as it is quite impossible that so many specimens could have been accidentally introduced by artificial means.

I have also to announce the capture of Deopeia pulchella at Wainuiomata, another welcome addition to our fauna. It is a very wide-spread species, but this is, I think, the first specimen which has been taken in New Zealand.

The beautiful Painted Lady butterfly (Vanessa cardui), has also been more abundant this year than I have known it since my arrival in 1881.

Hab. Otago. P.G.

I have never found this spider anywhere but in river-beds, and from the density of its pubescence I think it highly probable, though I have never seen it in water, that it seeks its prey in water as well as on land.

Lycosa œrescens, n. sp.

Mas.—Length, 9 ½ mm.

Cephalothorax greenish-brown, with a pale-yellow fleck on the caput behind each posterior eye, and a heart-shaped fleck of the same hue behind the junction of the caput with the thorax; lateral margins pale-yellow, with a fleck or two of brown; thoracic fovea reddish; falces reddish-brown; lip and maxillæ palish-brown; sternum brown; legs and palpi yellow, with brown extremities, and a few brown flecks on the femora, patellæ and tibiæ; abdomen above of the same hue as the cephalothorax, with a median longitudinal band of palish-yellow, bordered on each side by an irregular streak of brown, and extending from the base to a point somewhat beyond the middle, where the brown borders diverge, and thence towards the spinners crossed by short bars of brown; at the sides greyish mottled with brown; below reddish-brown, with two longitudinal rows of very minute brown spots, extending from behind the genital aperture to near the spinners. These spots are due to minute bald depressions in the integument. The whole body is rather densely covered with a fine pale pubescence.

Cephalothorax about 1 mm. longer than broad at its broadest part, not quite so long as the patella + tibia of a leg of the 4th pair, less than 2 mm. wide at the inferior margin of the fore part of the caput, and considerably narrower than this at the top in front.

Front row of eyes slightly bent backwards, small, centrals slightly larger than the laterals, and nearer to those than to each other; eyes of middle row distinctly larger than those of the hind row, and separated from the fore-laterals by about the diameter of one of the latter. The hind row is the longest, but the fore and middle row do not differ much in length. The eyes of the hind and middle row and the laterals of the front row are placed on black spots.

Falces long, somewhat convex and slightly diverging towards the extremities; groove toothed on both sides—on the underside 3, and on the upper side 2 teeth, the posterior one being the smallest on each side. Claw moderately long and slender.

Maxillœ convex, increasing gradually in width from the base to the anterior extremities, slightly rounded on the outside, and almost truncate in front, where there is a very dense tuft of hair on the inner angle of each.

– 207 –

superior and inferior pairs not differing greatly in length and strength.

Legs 1 and 2 almost equal, 4th pair the longest and the 3rd the shortest; no spines on the tarsi; metatarsi and tibiæ spinous above and below; patellæ and femora spinous above only (patellæ of 1st pair with only 1 spine above, or none).

Palpi spinous above, but without spines below; near the anterior extremity of the humeral joint 4 spines, and behind these, at considerable intervals, 1, 1; humeral joint about equal in length to the radial + the cubital joint, bent, laterally compressed, thickest at the anterior extremity; cubital joint slightly longer than the radial, but not quite so strong; digital joint much shorter than the radial and cubital together, beak-like in shape; bulbus genitalis situated at the base of the beak, globular in outline, deeply cleft from the middle to the anterior surface. From the inner lobe of the bulbus springs a curved horny process, the direction of which is outwards and backwards, and the exposed surface of which is almost plain.

I have but one example of the female of this species. It does not differ much in size from the male, and resembles it in colours and markings as well as in other essential specific characters. The vulva is brown, semicircular in outline, with sharp ends directed backwards, and consists of two roundish apertures separated by a septum, anteriorly very slightly and posteriorly greatly dilated.

Found under stones in the Valley of the Waitaki. P.G.

The species of Lycosa described above are easily distinguished by their colours and markings alone.

Fam. Theraphosoidæ.

Genus Hexathele, Ausserer.

The abdomen above of the same hue as the cephalothorax, with a fleck of brown at the base, and a median longitudinal dark knotted band commencing at a small distance behind this basal fleck, and extending towards the spinners to a point beyond the middle, from which point to the spinners the abdomen is crossed obliquely by a double row of 2 to 4 bands of the same hue. In some examples there are faint indications that at some stage of the animal's existence a pair of oblique dark bands is thrown off from each knot of the median band. On the ventral

– 208 –

surface the abdomen is brown, mottled with brown yellow; posterior side of spiracular plates whitish; spinners of the same colour as the legs. The whole body, except the cephalothorax, is copiously furnished with dark hair.

Cephalothorax as long as the patella + tibia of a leg of the fourth pair; about 1 mm. longer than broad at its broadest part, and rather more than 1 mm. narrower at the fore-part of the caput than at its broadest part; truncated in front and behind; slightly rounded at the side; pars cephalica high; pars thoracica low; thoracic fovea deep, broad and rounded behind, and narrower and somewhat angular in front; lateral furrows well-marked; caput and thorax distinct.

The eyes in two rows, the anterior row bent backwards, and the posterior forwards, the latter longer than the former; the fore-centrals round, and the fore-laterals largish, round, and posited somewhat obliquely, the centrals about as distant from each other as from the laterals; eyes of posterior row longish, round, and posited obliquely, the centrals much smaller than the laterals and almost contiguous to them, and about as distant from the fore-centrals as these are from the fore-laterals; the hind-laterals nearer to the fore-laterals than these are to the fore-centrals; a few bristly hairs behind the ocular area, and a tuft in front of the fore-centrals.

Falces very long and strong, projecting 5 mm. beyond the clypeus, strongly convex, almost glabrous on the outer side, and abundantly furnished with bristly hairs on the inner side and in front; claw long and moderately strong; groove with a large number of teeth on each side, those on the inner side large, and those on the outer side minute.

Maxillœ strongly diverging, in shape resembling the exinguinal joints of the legs and not differing greatly in length from them, the basal half furnished with short black spines, and the fore-margin with a fringe of fine reddish hair. Lip triangular in outline, about as broad as the base is long, convex, separated from the sternum by a semicircular groove, and armed in front with very short blunt spines.

Sternum broadly elliptical, emarginated at the anterior and somewhat pointed at the posterior extremity, the sides somewhat projecting opposite the 1st, 2nd, and 3rd pairs of legs, and behind each projection there is a roundish bald dent.

Abdomen broadly ovate, narrowest towards the base, 12 mm. long and 9 mm. broad at its broadest part, and projecting over the thorax.

The spinners of each fore-pair near each other; the outer short and truncated, the inner nearly as long again as the outer and rounded towards the extremity; the posterior pair very long, about 6 mm.

– 209 –

Palpi about as long as cephalothorax + falces; humeral joint much bent outwards, and laterally compressed; cubital joint thickened towards the fore-extremity and shorter than the radial joint, the latter not differing much in length from the digital joint; all the joints armed with spines, but the two anterior ones much more copiously than the rest, and the humeral and cubital have them above only, and the other joints at the sides and below only; digital joint terminated by a single pectinated claw.

Legs, 4, 1, 2 and 3 about equal; tarsi of 1st and 2nd pairs without spines, those of the 3rd and 4th pairs armed with spines below only; metatarsi of 3rd and 4th pairs armed with spines above and below, those of the 1st and 2nd pairs below and at the sides; tibiæ of all the legs furnished with spines at the sides and below, and those of the 3rd pair sometimes have one or two spines above; patellæ spinous at the sides only; femora all armed with spines above, but not below. At the fore extremity of the coxal joint there is a fringe of fine spines, and a few spines are found at the fore extremity of the exinguinal joint. Claws 3, long and strong; superior pectinated, inferior much bent but without teeth.

Mas.—The male resembles the female in colour and markings, except that the palpi and the 1st pair of legs are reddish-brown. The dimensions of the cephalothorax and its appendages—except the falces, which are much smaller—do not differ much from those of the female; but the abdomen, though its length and breadth have about the same ratio to each other, is much smaller. The tibiæ and metatarsi of the 1st pair of legs differ greatly in shape and armature from those of the corresponding pair in the female. The tibiæ are very turgid, and, in addition to the ordinary spines below and at the sides, furnished with two very stout bent spines at the fore-extremity, the inner of which is longer and stouter than the outer. The basal half of the metatarsi is bow-shaped, with the are directed upwards and outwards; the joint is much thickened at the anterior end of the are, and furnished with one spine in the middle and one at the anterior end, on the outside of the are, and two on the underside at the fore-extremity of the joint. Bulbus genitalis directed backwards, turbinate, and drawn out into a long, thin, slightly bent, sharp-pointed spine.

The tube is circular, very large and deep, not differing much in diameter throughout its whole length, and, like that of Nemesia, though less thickly, lined with web, but without a lid.

– 210 –

For an inch or two round the mouth there is spun a loose, coarse web, for the purpose, probably, of entrapping beetles and other insects that its occupant preys upon. This web appears to be more or less continuous with the lining of the nest, and makes the mouth of the tube appear slightly funnel-shaped. When the spider is absent on a foraging expedition, the nest is left quite open, but when it re-enters the nest it generally spins a few threads of web across it, at or near the top.

Genus Migus, Kirk.

Migus distinctus.

Mas.—Length, 9 mm.

Pars thoracica brownish-yellow, with the anterior and lateral margins of the fovea dark brown; pars cephalica greenish brown-yellow; sternum pale, and maxillæ brownish-yellow; lip of a greenish hue at the basal half, and of the same hue as the maxillæ towards the front; falces greenish brown-yellow with a bright reddish brown fang; the exinguinal and coxal joints of the legs pale yellow, the other joints and the palpi of the same colour as the falces. The abdomen above dark brown, minutely speckled with pale brown spots, and having two longitudinal rows of elongate, obliquely posited, spots of the same hue; below pale yellow towards the base, and of the same hue as the dorsal surface towards the spinners; spinners pale yellow. The cephalothorax is glabrous, except at the lateral margins, where there is a fringe of dark hairs directed upwards, and between the eyes and the fovea where there are a few dark bristly hairs directed forwards. The rest of the body and its appendages are furnished with hair.

Cephalothorax shorter than the patella + tibia of a leg of the 4th pair, rounded at the sides, about half as wide at the fore-angle of the caput as at its broadest part between the 2nd and 3rd pairs of legs, highest at the fore-central eyes, from whence it slopes gradually to the posterior margin; lateral slope not very steep; fovea semi-hexagonal in front and low and rounded behind; lateral indentations moderately well marked; caput distinct from the thorax, somewhat rounded in front; clypeus high, and slightly sloping forwards.

Both rows of eyes slightly bent forwards, and not differing much in length, the posterior bent more than the anterior; the fore-centrals each in a black tubercle, round, and rather less distant from each other than from the fore-laterals; the latter posited obliquely, longish, round, and somewhat larger than the former; eyes of posterior row sub-equal, slightly elongated, smaller than the fore-centrals; the laterals near the centrals but not contiguous to them; the laterals of both rows and the centrals of the hind row on a common black spot. The fore-centrals are the darkest in colour, and the fore-laterals are

– 211 –

darker than the hind-laterals, and these again darker than the hind-centrals, which are of a brilliant pearly lustre.

Falces moderately strong, prominent, knee-shaped, shorter than the patella of a leg of the 1st pair; groove-toothed, 4 small teeth on the outer and 3 large ones on the inner side; the basal half glabrous, the fore part sparingly furnished with hairs; claw moderately long and strong.

Maxillœ strongly diverging, sides parallel, at the fore end slightly rounded, on the outer end produced to a subconical point on the inner side; no spines on any part.

Lip triangular, rather longer than broad at the base, convex, and separated from the sternum by a semicircular groove.

The sternum ovate in outline, broadest behind, emarginated at the anterior and somewhat pointed at the posterior extremity; the sides projecting slightly opposite the 1st, 2nd, and 3rd pairs of legs.

Abdomen ovate, longer than the cephalothorax and about as broad. Inferior spinners short and slender, superior more than twice as long as the inferior, and very stout.

Palpi considerably longer than the cephalothorax, armed with spines on the superior side of the humeral joint, and on the inferior side of the radial joint, and with two longish slender ones near the fore-extremity of the digital joint; humeral joint bent, laterally compressed, and nearly as long as the cubital and radial joints together; radial joint much longer and much stouter than either the cubital or the digital joint; bulbus genitalis directed backwards, turbinate, and produced into a long, slender, sharp-pointed spine.

Legs 1, 4, 2, 3, the 1st and 4th not differing much in length; armed with hairs, bristles, and spines, the last most numerous on the femora and stoutest at the sides of tibiæ and at the fore-extremity, below, of the patellæ of the first pair. The other joints have few or no spines. The metatarsi of the first pair are only slightly bent at the basal half, but the tibiæ of the same pair are considerably stronger than those of the other pairs.

The female of this species has been described by Cambridge; but, as the male differs very considerably from the female, I have given a detailed description of it here.

Found at Ravensbourne, near Dunedin, by Mr. Petrie and myself. I have traced it from Portobello nearly to Oamaru. It is never found many feet from the sea beach. The male is very sprightly, but the female is very sluggish, and invariably simulates death upon being touched. It is able to live a long time without food. I kept a female in a corked tube without food for nearly two months, and at the end of this time it appeared not to have suffered the least from its long fast.

– 212 –

The nests, strongly resembling those of Nemesia, though many times shallower and much smaller, are built in clay banks, and at all angles between the horizontal and the vertical, but generally at an angle vertical, or nearly so, to the earth's surface.

Art. XXIX.On some New Native Plants.

[Read before the Wellington Philosophical Society, 19th January, 1887.]

Plates XIV.-XVIII.
Erigeron bonplandii, Buch.

A small shrubby very viscid plant, 10–12 inches high. Leaves numerous, linear obovate, obtuse, obscurely serrate, 2–4 inches long, ¾-inch at the broadest part, bright-green on the upper surface, and covered with close, white, shining tomentum beneath. Scapes 4, in the axils of the upper leaves. Stem bracts numerous, diminishing in size upwards. Heads nearly 2 inches in diameter, involucral scales in few series, long, linear, upright. Rays long, linear; anthers tailless. Pappus of few short hairs; achene with short rigid hairs on margins.

This very showy Erigeron was collected by Mr. Martin, on Mount Bonpland; there is a fine robust specimen growing in his nursery at Green Island. The large flower-heads of this species make it very attractive, and it is worthy of cultivation. This species is allied to Erigeron novœ-zealandiœ, figured in vol. xvii. “Trans. N.Z. Institute,” but-differs much from that species in its large leaves and numerous scapes.

Celmisia martini, Buch.

Rhizome stout. Leaf sheaths ½ inch in diameter. Leaves 12 inches long, ½ inch broad, obscurely serrate, linear-oblong, and tapering to an acute point at top, narrowing near the bottom to 1 inch, then spreading downwards into a broad villous sheathing petiole; under-surface covered with closely appressed white or very pale-buff tomentum; central vein dark-purple, dividing near the bottom into nine dark-purple veins; back of leaf covered, when young, with a white silvery pellicle, which afterwards breaks away, exposing the dark-green leaf. Scape stout, scarcely longer than the leaves. Bracts few, narrow, linear, 4 inches long, diminishing in size upwards. Head nearly 2 inches in diameter. Florets numerous, long, narrow, linear.

Hab. Mount Bonpland, 4,000 feet.

– 214 –

This fine Celmisia was collected by Mr. Martin on Mount Bonpland, and has succeeded well with him at his nursery at Green Island, where it was planted out, and bids fair to become a permanent plant of cultivation.

Aciphylla kirkii, Buch.

A rigid shining plant, 8–12 inches long. Leaves 8–9 inches long, ¾–1 inch broad. Leaves chiefly bifoliate, bifurcation 3–6 inches from top, obtuse, apiculate, finely marked with anastomosing striæ, and with a stout marginal nerve on both sides of the leaf, sheath at bottom membranous. Flowers diœcious. Male scape nearly straight, bracts long, 3-foliate. Female scape and bracts flexuose. Umbels numerous.

This well-marked species was collected on Mount Alta, in 1883, but as the only specimen then procured arrived at Dunedin in a very fragmentary state, it was laid aside. On a recent examination the material proved sufficient for a restoration, when carefully put together. Another species of Aciphylla may be looked for in the Wanaka District, of which I have only a fragment. The leaves are 12 inches long, smooth and shining, with the striæ only marked, and the serrations on the edges of the leaves scarcely felt.

Gastrodia hectori, Buch.

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

Root tuberous, stem and spike of flowers 18 inches high, closely sheathed for ⅔ of its length by a long leaf, ⅓ of the leaf being free, a short outer sheath at bottom encloses the base of the sheathing leaf. Scales none. Racemes 3 ¼ inches long. Flowers 13, close-set, brownish-yellow, 2/10 of an inch in length, seed-vessel black, or dark brown, orbicular.

The present species was collected several years ago in Marlborough district, near Picton, and has also been seen on the Conway River. The species of Gastrodia are probably abundant, but their dark habitats, in dense bush country, prevent them from being easily seen.

Ourisia montana, Buch.

A small erect hispid plant, 1–2 ½ inches high. Stems creeping; leaves few, linear, ovate, or obovate, entire, 1–1 ¼ inch long, ⅓–½ inch broad. Petiole one-third as long as the leaf. Scape 1 ¼ inch, with one very small bract. Flowers solitary, large for the size of the plant, pedicels slender, springing from the base, and with the flower topping the leaves. Corolla large, white, oblique, limb 5-fid., ¾ inch diameter. Calyx 5-partite.

The large entire leaves, long pedicels, and large flowers, distinguish this species from Ourisia uniflora and Ourisia colensoi. Collected on Mount Alta Range, at 5,000 to 6,000 feet altitude.

– 215 –

Olearia alpina, Buch.

A small ornamental alpine tree, 8–12 feet high, trunk 6–8 inches in diameter; branches, and leaves below, covered with pale buff tomentum. Leaves 5–6 inches long, ¼ inch broad, linear, entire on the margins, midrib very stout, veins close, diverging at right angles, thus forming a series of lacunæ on both sides of the midrib. Heads numerous, in large panicles, with diverging branches, involucres turbinate, flowers not seen; pappus reddish, whole inflorescence covered with brownish tomentum.

Common on the Tararua Mountains, and mountains towards Wanganui. A remarkable plant, closely allied to O. excorticata, Buch.; stems covered with thin brownish bark, which peals off in large papery sheets. This small tree is worthy of attention for ornamental shrubbery, although cultivation might rob it of much rugged beauty. Though closely allied to O. excorticata, Buch., the oblong leaf of that species presents when compared with the long linear leaf of this species a marked distinction.

Celmisia robusta, Buch.

A small robust branching species, 4–6 inches high. Leaves 1–1 ½ inch long, ½ inch broad, coriaceous, ovate-oblong, acuminate or rounded at the tip, and broadly sheathing at the base, finely toothed, greenish-white above and covered with closely appressed white tomentum beneath. Scape 4–5 inches long, with 6–10 linear bracts. Head 1 inch diameter; involucral scales numerous, subulate, tapering, often recurved. Pappus orange colour, ¼ inch long, achene pubescent.

The affinity of this hardy mountain plant is with C. hectori, but the large obovate olive-green leaves of this plant necessitate the formation of a new species.

Haastia montana, Buch.

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

Closely tufted, branches erect, and covered with soft fulvous wool over the whole plant. Leaves loosely imbricating, rounded on top, obovate, erect or recurved, veins of the leaves irregular, indistinct. Heads small, 6/10ths of an inch diameter, involucral scales reduced to fine black lines.

A very distinct plant from any of the other species of this genus. From H. recurva it may be distinguished by its large up-right soft leaves, and from H. sinclairi by the absence of the large black involucral scales, and altogether different foliage from either.

This addition to the genus Haastia was discovered on Mount Alta Range, Lake Wanaka.

Ranunculus muelleri, Buch.

A stout, robust, fulvous and villous plant, 5–6 inches high. Root-stalk stout, rootlets numerous. Leaves all radical, round,

– 216 –

crenate-lobed, 2 inches diameter, petioles 2 inches long. Peduncles few, 4–5 inches long. Flowers, 2–3 large, white, each flower with a broad linear bract underneath, and a flower-bud in the axil.

The present fine plant adds another species to the already large family of New Zealand Ranunculus. It was collected on the Tararua Mountains, the only specimen seen in flower, and has been since overlooked. I am indebted to Mr. Kirk for pointing out its claim as a new species.

Cassinia rubra, Buch.

A small delicate shrub, 2–4 feet high, with bright olive-green foliage. Leaves very small, erect, or decumbent, linear-oblong, obtuse, ¼–⅕ inch long, margins nearly flat. Heads of flowers dense, in close rounded corymbs. Flowers very small, numerous. Involucral scales in 3–4 series, bright pink or red.

This beautiful little plant was reported as collected on the Wanganui River, inland. No doubt such a beautiful shrub would prove a valuable addition to the gardens, if young plants could be procured and established.

Geum alpina, Buch.

A small, prostrate, hairy, mountain plant, with stout prostrate rhizomes. Leaves alternate, closely arranged, ½–¾ inch diameter, rounded, lobed, and with fine crenate serratures. Flowers minute, yellow, on numerous branches towards the end of the stems.

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

In extremely small forms of this plant, the leaves are much reduced in size, and the numerous little yellow flowers scarcely exceed the calyx, a head of flowers not exceeding 2/10 inch. No doubt this is a reduction of size entirely due to severe climatic influence.

Pachycladon elongata, Buch.

A small glabrous, open-branched, alpine plant. Root long, fusiform, elongate. Leaves few towards the bottom, ¾-inch long, with 5–7 deep serratures. Upper and largest portion of plant composed of flowering racemes, which are afterwards replaced by long slender siliqua or pods, 1 inch long.

It would appear that a gradation of form can be traced in the genus Pachycladon, from Hooker's Pachycladon novœ-zealandiœ, through P. glabra, Buch., to the present attenuate form, which may be named Pachycladon attenuata, Buch. The gradation of form in this case cannot be ascribed to climatic influence, as the three species were all collected at the same altitude and locality, Three Kings Mountain, 5,000 feet altitude.

Art. XXX.On a remarkable branching Specimen of Hemitelia smithii.

[Read before the Wellington Philosophical Society, 19th January, 1887.]

Plates XII., XIII.

The visitor to the slopes of Mount Cargill, near Dunedin, may have noticed the marked abundance of that beautiful tree-fern Hemitelia smithii, which often attains there a height of 20–30 feet; and he may also have noticed a strong tendency in this species to divide at the top of the stem into two, and sometimes three, branches. But a remarkable departure, however, from this limited terminal branching has been discovered, which forms the subject of the present paper. The accompanying sketch, drawn from measurements, proves the tree to have been 16 feet in height, and that it has 16 branches, as also several buds. The budding and branching may proceed from any part of the stem, and the specimen has several branches diverging in various directions, which again divide, as in dicotyledonous trees. The accompanying drawings (Plates XII. and XIII.) have been sketched by measurements taken from the fallen tree, it having recently been cut down by some boys.

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

The transverse sections are intended to illustrate the method of branching in this specimen of tree-fern; they are all drawn one-third natural size, except diagram A B, which is 1/135 natural size.

There is one remarkable feature in connection with the true or inner stems and branches of tree-ferns: that is, the point of attachment of the branch with the inner or true stem does not increase much in diameter for several inches from the parent stem; it then gradually enlarges in an upward direction, and becomes covered by the fibrous mass. A weakness in branches might be suggested from this; but the great strength of tree-ferns is due to the strong fibrous matter enveloping them, which is remarkably strong, and would prove as reliable for a transverse strain as many timbers; they have often been used for short bridges, both as stringers and flooring.

In the diagrammatic section, A B, is shown the method of branching in this tree-fern: a branch is produced from a small bud, which pushes its way through the woody inner or true stem of the tree, and also the close fibrous outer covering. (See longitudinal section of A 1, where a transverse and longitudinal section is shown of the method of branching.) The large sections (B B and B 3) are cut 3 feet above A, showing the increase of size in 3 feet of the central core.

Art. XXXI.On the New Zealand Species of Coprosma.

[Read before the Auckland Institute, 18th October, 1886.]

Next to Veronica, the genus Coprosma is the most puzzling in the New Zealand Flora. Not only are the species highly variable in their mode of growth, foliage, and vegetative characters generally, but the flowers are so small and inconspicuous, and so uniform in their structure, as to offer few distinctive characters of importance. It is thus no easy matter to identify the species even when they are examined in a fresh state, while in the case of dried specimens, it requires the utmost care to arrive at any satisfactory conclusions.

For a considerable time I have made the New Zealand Coprosmas a subject of special attention. Most of the species I have seen living in their native stations, and have thus had opportunities of tracing the variations due to differences in soil, altitude, and exposure. I have been enabled to collect large suites of specimens from all parts of the colony, and, in addition, have been favoured with others made for me by friends. Through the kindness of Sir Joseph Hooker, sets of my specimens have been compared with the types of the species described by Cunningham and others, and now preserved in the Kew Herbarium, so that my identifications have been rendered more certain. The information and materials that I have collected I now propose to make use of in drawing up a systematic account of the species, with the view of rendering their determination more easy, and of supplying, as far as I can, the admitted deficiencies existing in all previously published accounts.

The genus Coprosma belongs to the Rubiaceœ, or Madder family, represented in the temperate regions of the northern hemisphere by a sub-tribe (Stellatœ) of low-growing herbaceous plants, comprising, among others, the well-known Madder, Woodruff, Cross-wort, etc. It is, however, in the tropics and in the south temperate zone that the more typical members of the family are found. Many of these are highly ornamental, and are often seen in our gardens and greenhouses, as the various species of Bouvardia, Ixora, Gardenia, etc. Two well-known economic plants are also included—the Coffee shrub, and the quinine-producing Cinchona. The close alliance of these plants to Coprosma has led to the suggestion that its bark should be examined for quinine, or the allied alkaloids, and the berry for caffeine. I believe that no exhaustive chemical examination has yet been made, but some preliminary investigations that have been made by Mr. Skey and others do not warrant very favourable expectations.

– 219 –

The first species of Coprosma were collected in 1769 by Banks and Solander, during Cook's first voyage. Specimens of six species were brought home to England, and are now preserved in the Banksian Herbarium in the British Museum. In the manuscript account of the plants of New Zealand, drawn up by Dr. Solander, but which, for some unexplained reason was never published, although made quite ready for the press, even to the preparation of the engravings, the name Pelaphia was proposed for the genus; and the species were also fully and clearly described. However, as Dr. Solander's names were never actually published, they can have no standing in botanical works.

During Cook's second visit to New Zealand, in 1772, he was accompanied by Forster, the well-known naturalist. Plants were collected at Queen Charlotte Sound and Dusky Bay, and many of them were subsequently described by Forster in his “Prodromus.” The term Coprosma was now for the first time applied to the genus, and two species described—C. lucida and C. fœtidissima. For many years these remained the only species actually published from New Zealand.

Nothing more was added to our knowledge of Coprosma until Allan Cunningham made his two visits to New Zealand in 1826 and 1838. In his “Precursor to a Flora of New Zealand,” which contains the results of these journeys, ten species are enumerated. Three of these are mere synonyms; and two more were already known. The remaining five are good and distinct forms. Cunningham's descriptions, however, are extremely imperfect, and in many respects faulty and misleading. The types of his species are now preserved at Kew; but, according to Sir Joseph Hooker, (“Handbook,” p. 111), the specimens have been much intermixed by himself.

In 1846, M. Raoul published in his “Choix de Plantes de la Nouvelle Zelande,” a description of Coprosma robusta, perhaps the most widely distributed of all our species, but which seems to have been confounded with C. lucida by previous botanists. About the same time Mr. Colenso contributed to the Tasmanian “Journal of Natural Science” a paper entitled “A Tour in New Zealand,” in which several additional species were made known. This was afterwards reprinted in Hooker's “Journal of Botany;” but, unfortunately, I have been unable to obtain a copy. I much regret this, as it is possible that some of Mr. Colenso's species may be identical with some of those described by later writers; and, if so, his names should take precedence.

Hooker's “Flora Antarctica,” which appeared in 1845, contains an account of the Coprosmœ collected by the author in the Auckland and Campbell Isles in 1840. Seven species were enumerated, six of which were considered to be new. But of these C. affinis has since been referred by its author to C.

– 220 –

fœtidissima; C. myrtillifolia, which was based on barren specimens, has been abandoned, and is probably identical with C. parviflora; while it is doubtful whether there is any real distinction between C. repens and C. pumila.

In 1854, Sir Joseph Hooker brought out his “Flora Novæ Zealandiæ.” Botanists resident in New Zealand, especially Mr. Colenso and Dr. Sinclair, had sent large collections to Kew to be used in the preparation of this work, and among them no small number of Coprosmœ. The material thus brought together, though still imperfect, was much more extensive than that at the disposal of any of Hooker's predecessors, and it is needless to say that it was worked up with his customary care and accuracy, with the result of producing the first intelligible and comprehensive account of the genus. Nineteen species were described, of which five were new. The principal mistake made was in confusing a number of distinct and dissimilar species under the head of C. myrtillifolia, C. divaricata, and C. propinqua; but probably the specimens were not good enough, or complete enough, to show the distinction existing between them.

The arrangement followed in the more recently-issued “Handbook,” differs slightly from that given in the “Flora,” but there are no changes of any importance. The species confused with C. propinqua and C. myrtillifolia (= C. parviflora) are separated and put into their proper places, but no less than four distinct species are still included in C. divaricata. The disadvantage of working entirely on dried specimens is shown by the fact that in the specific descriptions hardly any use is made of the shape of the fruit, whereas it often gives good distinctive characters. The total number of species admitted in the “Handbook” is 24. Since its publication, no memoir treating of the genus as a whole has appeared, although from time to time new species have been described by Mr. Kirk, Mr. Petrie, Mr. Colenso, and myself.

The following summary sketch of the range of variation in the vegetative and floral characters of the genus may be useful to those who have not previously studied the species in detail:—

Habit, etc.—The greater number of the species are closely-branched shrubs, varying from 6 to 12 or 15 feet in height. Some attain the stature of small trees, the largest being C. arborea, which is, sometimes 30 feet in height, with a trunk 18 inches in diameter. C. baueriana is remarkable for its great range in size, according to situation and exposure. When growing on black maritime rocks it is often under 2 or 3 feet; while in sheltered places, on rich sandy soil, specimens 25 feet in height have been measured. C. areolata, C. propinqua, and C. fœtidissima occasionally reach 15 or 20 feet, although usually less than that. C. serrulata is the smallest of the large-leaved

– 221 –

species, and is generally under 4 feet in height. C. spathulata and C. rhamnoides have an average height of from 4 to 6 or 8 feet. C. acerosa has long and flexuous branches, often (in the typical form) much and closely interlaced, forming a dense bush 2 to 4 feet high; but some states of it are prostrate and sparingly branched. C. depressa is prostrate or sub-prostrate, and often under 1 foot in height. C. repens and C. petriei are the smallest species of the genus. They have prostrate and rooting, almost herbaceous, stems, closely appressed to the ground, and frequently only a few inches long.

The arrangement and disposition of the branches occasionally afford characters of importance: thus C. areolata can be at once distinguished from its nearest allies (C. tenuicaulis and C. rotundifolia) by its comparatively narrow and almost fastigiate outline. The mode of branching of C. propinqua, C. parviflora, C. acerosa, and others is characteristic of the species, and gives important aid in their identification.

Leaves.—In Coprosma, as in so many Rubiaceœ, the leaves are invariably opposite, entire, petiole, or sub-sessile, and connected by interpetiolar stipules. In size there is considerable range. C. grandifolia often has them as much as 9 inches in length, while in C. repens and C. petriei they are frequently under ⅛ inch. The large-leaved species C. grandifolia, C. lucida, C. robusta, C. baueriana, etc., have a well-developed many flowered inflorescence, and thus form a fairly well-characterized section of the genus. In the small-leaved species the flowers are either arranged in few-flowered fascicles or are solitary. As to shape, the leaves may be orbicular, ovate, oblong, lanceolate, or even linear. In the same species there is often considerable diversity of shape, and in C. rhamnoides leaves varying from orbicular to linear may be observed on the same bush. C. serrulata has the margins of the leaves minutely serrulate. All the other members of the genus have them quite entire when mature, but in some the very young leaves are obscurely incised. This is well seen in C. robusta. The texture varies considerably—from very coriaceous in C. lucida, C. robusta, and C. crassifolia to comparatively thin and membranous in C. rotundifolia and C. tenuifolia. The venation is pinninerved, at any rate in the great majority; but some of the small-leaved species have few lateral veins, although the midrib is always conspicuous and well developed. The veins frequently anastomose, in some forming copious minute reticulations, as in C. tenuifolia; in others larger areoles, as in C. areolata and C. tenuicaulis. All the species have a stout vein running round the whole of the margin of the leaf, and often giving it a thickened appearance.

In nearly all the species, except a few of the smaller-leaved ones, curious little pits exist on the under-surface of the leaves,

– 222 –

in the axils formed by the union of the primary veins with the midrib. They are never more than ⅛ inch in length, and are usually much less. Inside they are lined with numerous stiff white hairs, which, on being treated with caustic potash, are seen to be composed of two or three cells. So far as I have observed, the pits do not secrete anything, and I am quite unable to guess at their function. They are often inhabited by a minute yellow acarid, which makes use of them as a home. Sometimes two or three acarids may be found in the same pit, and they crawl freely about the young leaves and branches.

Stipules.—All the species possess interpetiolar stipules. They are more or less triangular in shape, often with minute denticulations towards the apex. The margins, or the whole surface, are frequently ciliated or puberulous. At their bases they are generally connate with the petioles, thus forming a short sheath round the branch. In C. linariifolia, especially on the young leafy branches, the sheaths are elongated, and form a very conspicuous, though variable character.

At the apex of the very young stipule a gland is situated which secretes a copious supply of a viscid mucilaginous fluid. These glands are highly developed and in an active state when the adjacent leaves are in the early stages of growth, but shrivel up and cease to secrete long before the leaves attain their full size. Their office is evidently to keep the young and tender leaves and branches plentifully bathed with fluid.

Indumentum.—Many of the species have puberulous or pubescent branches, and some have the under-surface, or both surfaces, of the leaves similarly provided, C. rotundifolia, C. areolata, and C. ciliata being perhaps the most conspicuous examples. The degree of pubescence is, however, a very variable character throughout the genus, and can only be employed with considerable caution for systematic purposes.

Inflorescence.—It is not always easy to understand the arrangement and position of the flowers, especially in some of the small-leaved species. The most developed inflorescence is seen in C. grandifolia, where it consists of trichotomously-divided many-flowered cymes, springing from the axils of the leaves. These cymes are often 3 inches in length, and bear from 20–40 flowers in the males, but a much smaller number in the females. At each division of the axis is a pair of connate leaf-like bracts. The ultimate divisions terminate in little clusters of flowers, each cluster being enclosed at the base by a shallow involucel formed by a pair of depauperated leaves and their stipules. Minute bracts are also present at the base of each flower. In C. lucida the inflorescence has precisely the same structure, but through the internodes of the primary and secondary axes being shortened it is much more compact. The internodes being still further reduced in length, we reach the arrangement seen in

– 223 –

C. robusta, where the flowers are congested into a dense many-flowered glomerule, or with two or three superposed glomerules. In C. baueriana, C. petiolata, and C. cunninghamii, the flowers are much less in number than in C. robusta, but their arrangement is on the same principle. In C. arborea the glomerules are rounder, and even more compact, and in addition to occupying the axils of the leaves, they often terminate the branches, which is never the case in C. robusta.

In the small-leaved species the flowers are much reduced in number, and are often solitary, especially the females. As to their arrangement, there are two main types, but they graduate insensibly into one another. In the first, the flower, or fascicle of flowers, is placed in the axil of a leaf, and is thus axillary. If, however, the pedicel of the flower is examined, it will be seen that in all cases two or three series of connate bracts are placed under the flower. The upper series forms a cup-shaped involucre, closely investing the base of the flower, and can be easily mistaken for a calyx, especially in the males, where the true calyx is either much reduced or altogether absent. These connate bracts evidently represent depauperated leaves and their stipules, so that the flowers really terminate minute arrested branchlets. This is the arrangement seen in C. rotundifolia, C. areolata, and C. tenuicaulis. In the second class the flowers quite obviously terminate leafy branchlets. In C. fœtidissima, C. colensoi, etc., they are placed at ends of the main branches, as well as on lateral branchlets, and several pairs of well-developed leaves are usually present, in addition to the bracts mentioned above. In other species (C. propinqua, C. parviflora, etc.), the flowers terminate short lateral branchlets only. As these branchlets are frequently much reduced, and often have only one pair of small leaves below the bracts, there is really not much to distinguish the inflorescence from that of the first type. This is particularly the case when the leaf at the base of the branchlet, and from the axil of which it has sprung, is persistent, as frequently happens.

Flowers.—The flowers are unisexual, and the sexes are placed on different plants. Occasionally, however, a few male flowers are intermixed with the females, and vice versâ. Some species, and especially C. robusta and C. fœtidissima, now and then produce hermaphrodite flowers, to all appearance well-developed and perfect, but which seldom mature fruit. The flowers are very uniform in shape all through the genus, and thus are of little value in the discrimination of the species.

The males are always larger and more numerous than the females. They have a broad or narrow campanulate corolla, divided half-way down, or further, into four or five lobes. The calyx, in the species in which it is present, is minute and cupular, and either truncate or obsoletely 4–5-toothed. In C.

– 224 –

arborea and C. spathulata, however, it is much larger, and has well-developed linear lobes. Most of the small-leaved species do not possess even the rudiment of a calyx, so far as the male flowers are concerned, but its place is well supplied by the cupular involucel previously alluded to. This involucel is a shallow cup-shaped organ, closely investing the base of the corolla. It is usually four-lobed, two of the lobes being rather larger than the others, but sometimes is quite truncate. It corresponds so closely in shape and position to a calyx as to be readily taken for one, and, in fact, it has often been described as such by authors. But there are sufficient reasons for believing it to be composed of a pair of depauperated leaves and their connecting stipules. In the first place, a similar involucel exists in the female flowers, where the true calyx is always developed; and in the second, if a sufficient number of specimens are examined, examples can be found where the two longer lobes are better developed, and evidently answer to metamorphosed leaves. In some species, and notably in C. acerosa, it is possible to trace a gradation of forms, from instances where the two longer lobes are hardly distinguishable from ordinary leaves, to cases where they are reduced to minute prominences on an otherwise truncate involucel. It should be mentioned, too, that the long lobes of the involucel are always placed crosswise (or decussately) to the pair of undoubted leaves below, which is precisely the position they ought to occupy on the assumption that they are metamorphosed leaves.

The stamens, which are either four or five in number, have long slender filaments, and rather large oblong anthers, which hang pendulous from the mouth of the corolla, swinging about with every breath of air. The pollen is small, smooth, and elliptical, and is produced in large quantities.

The female flowers are smaller and narrower than the males, approaching tubular in shape. The calyx tube is adnate to the ovary; the limb is almost always minute, and either obsoletely 3–5-toothed or truncate at the mouth. In C. arborea, C. spathulata, and C. linariifolia, however, the limb has comparatively long linear lobes. The styles are two, very long and slender, being often several times longer than the corolla. They are free to the base, and are covered with stigmatic papillæ for their whole length. The ovary is normally two-celled, with a single ovule in each cell; but frequently it is three- or four-celled, and more rarely six-celled. In C. repens it is quite common for the ovary to be four-celled.

Fruit.—This is a drupe with two (rarely four or six) one-seeded plano-convex pyrenes, applied to each other by their flat faces. In shape it varies from oblong or ovoid to globose; and in size from ⅛–¾ inch. The colour is chiefly orange or red; but some species have a semi-transparent colourless drupe (C.

– 225 –

arborea, C. cunninghamii, etc.). In others it is blueish (C. acerosa, C. parviflora), and in some black (C. spathulata, C. tenuicaulis, etc.). The shape is pretty constant in each species, and hence it is of considerable value as a distinguishing character; but the size, and to a lesser degree the colour, are very variable.

Fertilization.—All the species appear to be wind-fertilized. When a male tree in full flower is shaken, clouds of the loose incoherent pollen are driven off; and the long projecting styles of the female flowers, densely clothed with stigmatic papillæ, are well calculated to catch the pollen. As a rule, insects are seldom seen on the flowers of any of the species. A small dipterous insect occasionally visits those of C. robusta and C. propinqua, apparently to feed on the pollen; but I have never observed it on the female flowers, and consequently it cannot aid in the fertilization of the species.

Distribution of the species.—Of the thirty-one species admitted, all but three are confined to New Zealand, including in that term the adjacent groups of the Kermadecs, the Chathams, and the Auckland and Campbell Islands. The species found outside the Colony are the following:—C. baueriana, which is plentiful in Norfolk Island; C. petiolata, which occurs both there and in Lord Howe Island; and C. repens (C. pumila), which is found on the mountains of Victoria and Tasmania.

In the systematic portion of this paper the distribution of the species within the Colony is given as fully as possible, so that it is unnecessary to dwell on that point here. With respect to the character of their habitats, the species may be roughly divided into the following five classes:—

1.

Maritime, including C. baueriana, C. petiolata, and the typical form of C. acerosa.

2.

Lowland species of wide and general distribution, with no marked preference for any particular soil or situation, such as C. robusta, C. lucida, C. grandifolia, etc.

3.

Lowland species preferring swampy forests or rich alluvial soils—C. propinqua, C. rotundifolia, C. areolata, and several others.

4.

Lowland species with a local and confined distribution, as C. spathulata, C. arborea, etc.

5.

Species confined to hilly or subalpine localities, as C. fœtidissima, C. colensoi, C. cuneata, C. repens, and a few others.

Before passing to the systematic part of the paper, I have to tender my most sincere thanks to several gentlemen for their kind assistance in its preparation. To Mr. Petrie, of Dunedin,

– 226 –

I am especially indebted. From him I have received copious and well-selected suites of specimens of the Otagan species, accompanied with descriptive notes of great value. In addition to this, he has communicated to me, in the course of a correspondence extending over several years, very many original and important observations derived from his own study of the genus, and which have been of great use to me. Such liberal and generous assistance is as rare as it is valuable. I have also to thank Mr. Colenso, Mr. Hamilton, Mr. Adams, Mr. Reischek, and others for specimens of species of the genus, and for information respecting them.

There remains for me to acknowledge the very important aid afforded by Sir J. D. Hooker and Mr. N. E. Brown, of the Kew Herbarium. The latter gentleman has most kindly made a comparison of my specimens with the types preserved at Kew, drawing up a special report on all points of interest; and his conclusions have been examined and verified by Sir J. D. Hooker. My warmest thanks are due to both.

– 230 –

Quoted from Otago by Mr. Buchanan (“Trans. N.Z. Inst.,” i., p. 43), but I have seen no specimens from thence.

A large, sparingly-branched shrub, 8–15 feet high, with dark-brown bark. Leaves much the largest of the genus, 5–9 inches long, obovate-oblong or elliptic-oblong, acute, dull green, not shining or glossy, membranous, veins very finely reticulated. Peduncles 1–3 inches long, trichotomously divided. Flowers in fascicles at the ends of the divisions of the peduncle, each fascicle being enclosed in a shallow involucre formed by a pair of reduced leaves (bracts) and their connecting stipules. A distinct though minute calyx is present in both sexes. Male corolla ⅓ inch long, funnel-shaped. Female much smaller, ⅕–¼ inch, tubular, Drupe about ⅓ inch long, oblong, obtuse, yellowish-orange.

One of the most distinct species of the genus. The large foliage and well-developed inflorescence separate it from all its allies. C. lucida approaches it in inflorescence, but is at once distinguished by the much smaller more obovate coriaceous leaves, and by the stouter and more compact habit. C. tenuifolia has leaves very near in outline, colour, texture, and venation, but they are much smaller; and, judging from the fruit, the inflorescence is very different.

Mr. Colenso has very kindly favoured me with flowering and fruiting specimens (collected at Hawke's Bay) of a Coprosma labelled “C. latifolia, Col.,” and which I understand he has lately described as a new species closely allied to C. grandifolia. After a careful examination, however, I have failed to find any characters to separate his plant from C. grandifolia, even as a variety. The leaves are perhaps a trifle more obtuse than is usual, but otherwise I see no difference at all from the ordinary form common near Auckland and in many other places.

2. C. lucida.

North Island.—Common throughout, from the North Cape to Wellington. Altitudinal range from sea-level to over 3,000 feet.

South Island.—Nelson, plentiful, T.F.C.; Marlborough, J. Buchanan; Westland, A. Hamilton!; Canterbury, in Banks Peninsula and lowland districts, J. B. Armstrong, T.F.C.; Otago, common on the south-east and west coasts, not so plentiful in the north or in the interior, D. Petrie!; Stewart Island, plentiful, D. Petrie.

A handsome stout leafy shrub, 4–15 feet high, perfectly glabrous in all its parts. Leaves 2–5 inches long, oblong-obovate,

– 231 –

oblong-lanceolate, or elliptic-oblong, coriaceous, obtuse, apiculate or acute, gradually narrowed into short stout petioles, pale glossy-green. Peduncles 1–2 inches long, trichotomously divided. Flowers numerous, in fascicles at the ends of the divisions of the peduncle. Calyx present in both sexes, but limb very inconspicuously toothed. Male corolla ⅕ inch long, broadly tubular; female rather shorter and narrower. Drupe ⅓–½ inch long, oblong or oblong-obovoid, obtuse, yellowish-orange.

C. lucida varies considerably in habit. When growing in the open it usually forms a dense round-topped shrub; but when met with as undergrowth in the forest it is much more sparingly branched, and the branches are much longer and spread more. It is allied by its inflorescence to C. grandifolia, but is at once recognised by its very different foliage and habit. From C. robusta it is removed by its paler obovate more coriaceous leaves, which dry a yellowish-green, and not blackish-brown as in that species; and by the longer peduncles and more open inflorescence. The drupe is also much larger and much more pulpy and juicy than that of C. robusta. There is no danger of its being confounded with any other of the large-leaved species. In the “Handbook” the leaves are erroneously described as membranous, probably from becoming thin when dried. In the fresh state they are always coriaceous.

3. C. serrulata.

Hook. fil., MSS.; Buchanan, Trans. N.Z. Inst., iii., p. 212; Kirk, l.c. x., App. p. xxxv.

South Island.—Sub-alpine localities, but not very common. Nelson, slopes of Mount Arthur and Mount Peel, 3,000 to 4,000 feet, T.F.C. Canterbury, mountain districts above 2,000 feet, J. B. Armstrong!; Arthur's Pass, Waimakariri Glacier, mountains near Lake Tekapo, T.F.C. Otago: Mount Ida, 2,000 to 3,000 feet; Mount St. Bathans, 2,000 to 3,000 feet; Mount Tyndall, 4,000 feet, D. Petrie!; Dusky Bay, on the mountains, A. Reischek!

A robust, leafy, sparingly-branched dwarf shrub, 1–4 feet high, perfectly glabrous in all its parts. Branches few, stout, straggling; old bark white and papery. Leaves coriaceous, 1–2 ½ inches long, oblong-obovate, broadly obovate, or nearly orbicular, rarely narrower and elliptical-oblong, obtuse or apiculate, narrowed into a short broad petiole; margins thickened, minutely serrulate; veins reticulated, very conspicuous on the under-surface. Stipules very large, triangular, margins ciliated. Inflorescence diœcious. Males: in axillary 3–7-flowered fascicles. Calyx apparently wanting. Corolla ¼–⅓ inch long, between

– 232 –

funnel-shaped and campanulate, 4–5-lobed. Stamens, 4–5. Females: solitary, or in 3–5-flowered fascicles. Calyx adnate to the ovary, limb minute, cupular, sometimes with a few irregular teeth. Corolla ⅕–¼ inch long, tubular, shortly 3–5-lobed. Styles long and stout, often 1 inch long, cohering up to the mouth of the corolla. Drupe broadly oblong or sub-globose, ¼–⅓ inch long, reddish.

A remarkably distinct plant, at once recognized by the minutely serrulate leaves. It is usually found in sheltered places on steep mountain slopes, and rarely attains a greater height than four or five feet. The bark of the stem and branches is white and papery, and is easily detached. The leaves are often very coriaceous, perhaps more so than in most of the species. The male fascicles are often reduced to three or four flowers, and occasionally to a single one. The female flowers are generally solitary, although there is no difficulty in finding specimens with fascicles of three, and, more rarely, with five flowers.

It may be remarked, in passing, that in several of the species the very young leaves have their margins minutely incised or serrate, but the character is always an obscure one, and is never present in fully mature leaves, except in C. serrulata.

4. C. baueriana.

Endl., Iconog., t. iii.; Hook. fil., Flora Nov. Zeal., i., p. 105; Handbk. N.Z. Flora, p. 112. C. lucida, Endl., Prodr. Flor. Ins. Norfolk, p. 60, non Forst. C. retusa, Hook, fil., Lond. Journ. Bot., iii., p. 416. Pelaphia retusa, Banks et Sol., MSS.

North Island.—Abundant all round the coasts, on maritime rocks and sand-hills, but not found inland, save where planted by the Maoris in the cultivations, etc.

South Island.—Southern shores of Cook Strait, from Collingwood to Picton, but not common.

Chatham Island.—J. Buchanan (“Trans. N.Z. Inst.,” vii., p. 336). Also found in Norfolk Island.

A shrub or small tree, very variable in size and habit of growth, in exposed rocky places often not more than 2–3 feet high, with almost prostrate branches; in rich sandy soils sometimes 15–25 feet, with a close head of spreading branches. Branches stout, glabrous, or the young ones minutely pubescent. Leaves bright shining green, almost fleshy, black when dry, 1–3 inches long, broadly ovate or oblong, rarely narrow oblong, obtuse or retuse, rarely sub-acute, quite glabrous; margins usually recurved, and often conspicuously so; veins finely reticulated. Stipules short and broad. Male flowers clustered in dense heads on short axillary peduncles. Calyx minute, cupular, obsoletely 4-toothed. Corolla campanulate, ⅕–¼ inch,

– 233 –

4–5-lobed. Females: Peduncles smaller and more slender than in the males, and heads smaller, rarely more than 3–6-flowered. Calyx-limb minute, truncate or obsoletely 4-toothed. Corolla smaller and narrower than in the males. Drupe oblong or ovoid, ¼–⅓ inch long, yellowish-orange.

I doubt whether there is any real distinction between this species and C. petiolata. From C. robusta it is separated by its stouter and closer habit, more obtuse, and much more fleshy and glossy leaves, with recurved margins, by the smaller heads of flowers, and by the rounder fruit.

C. baueriana is more frequently seen in cultivation than any other species, chiefly on account of its very handsome glossy foliage and compact habit. States having the leaves variegated with white or yellow are not uncommon, and have been introduced into European gardens. It forms an excellent hedge, and as it is not easily affected by exposure to salt spray or drifting sand, is very suitable for planting in exposed places near the sea. Thus, at Taranaki, luxuriant garden hedges composed of it may be seen in situations open to the full force of the westerly gales.

At Maketu, in the Bay of Plenty, there exists a grove of this species, which the Maoris state had its origin from the skids which were used in pulling ashore the Arawa canoe, on its arrival in New Zealand with the first Maori immigrants. It is said that the skids were brought in the canoe from Hawaiiki, but the acceptance of this statement is rendered difficult by the fact that C. baueriana is not known to occur anywhere in Polynesia, or, indeed, out of New Zealand, save at Norfolk Island.

Kermadec Islands.—McGillivray.

Also found in Lord Howe's Island and Norfolk Island.

With this species I am imperfectly acquainted. According to Sir Joseph Hooker it is distinguished from the preceding by the leaves being less fleshy, and by the young foliage and branches being covered with a minute pubescence. But C. baueriana often has the young branches covered with a minute velvety pubescence, and the leaves vary in texture. Sir F. Mueller, in his “Fragmenta” (vol. ix., p. 69), unites both species, and probably this is the correct view to take.

6. C. robusta.

Raoul, Choix des Plantes, 23, t. 21. Hook. fil., Flora Nov. Zeal., i. p. 105; Handbk. N.Z. Flora, p. 113.

North and South Islands.—Common in lowland districts, from the North Cape to Invercargill.

Chatham Islands.—J. Buchanan (“Trans. N.Z. Inst.,” vii., p. 336).

A stout, leafy, glossy-green shrub, 6–15 feet high, perfectly glabrous in all its parts; bark greyish-brown. Leaves coriaceous, very variable in size and shape, 1 ½–5 inches long, lanceolate to broad elliptic-oblong, acute, rarely obtuse, narrowed into short stout petioles, dark-green and shining above, paler below. Flowers clustered in axillary many-flowered glomerules. Males: Calyx minute, cupular, minutely 4–5-toothed or quite truncate. Corolla ⅕–⅓ inch long, campanulate, shortly or deeply 3–5-lobed. Stamens, 3–5. Females: Much smaller, ⅙–¼ inch long. Calyx-limb truncate, or rarely with a few irregular teeth. Corolla tubular, shortly 3–5-lobed. Drupes densely packed, oblong to ovoid, rarely obovoid, ¼–⅓ inch long, yellowish- or reddish-orange.

C. robusta, has a very wide and general distribution. Unlike many of the other species, it is not restricted to any particular class of habitat, but is seen in all soils and situations, whether sheltered or exposed, near the sea or inland. As a rule, however, it does not ascend the mountains to a greater height than about 2,500 feet. In its ordinary state it is not at all difficult to recognize. The characters separating it from C. lucida I have pointed out under that species. From C. baueriana it is chiefly distinguished by its firm coriaceous leaves, which are not at all fleshy, by the much larger fascicles of flowers, and by the rather smaller and more pointed fruit. From C. cunninghamii it differs in the larger broader leaves, much more numerous flowers, and in the colour of the drupe, which appears to be always pale and transparent in C. cunninghamii. I have, however, intermediate forms which are difficult to place, judging from foliage and inflorescence alone. From C. acutifolia, C. tenuifolia, and C. arborea, it is at once separated by the texture and shape of the leaves, and by numerous other points.

North Island.—Not uncommon in the lowlands, chiefly in alluvial grounds by the banks of rivers.

South Island.—Usually near the coast. Various localities in Nelson, T.F.C. Banks Peninsula and lowlands of Canterbury,

Chatham Islands.—Dieffenbach (“Handbook”); Buchanan (“Trans. N.Z. Inst.,” vii., p. 336).

Altitudinal range from sea-level to 500 feet.

A large, sparingly-branched shrub, or small tree, 6–15 feet in height; bark pale. Leaves flat, coriaceous, variable in size, ½–2 inches long, usually linear or linear-lanceolate, but occasionally broader and shorter and linear-oblong, acute, gradually narrowed into short stout petioles. Inflorescence composed of 3–12-flowered axillary glomerules. Male flowers ⅙–⅕ inch long. Calyx minute, cupular, truncate, or obscurely lobed. Corolla campanulate, 4–5-lobed. Female flowers much smaller and narrower. Calyx-limb 4–5-toothed. Corolla ⅛–⅙ inch, tubular, 3–5-lobed. Styles very long and stout. Drupe broad-oblong or sub-globose, pale, and semi-transparent.

Most closely allied to the preceding species, but in its usual state differing in the more slender open habit, pale bark, much smaller and narrower leaves, smaller fascicles of flowers, and particularly in the rounder, pale, and semi-transparent fruit. Intermediate states are plentiful, and some are very puzzling to place in the absence of fruit, especially some Otago specimens sent by Mr. Petrie, and which may be referable to small and narrow-leaved forms of C. robusta. It is also related to C. propinqua, which, however, can be easily separated by its more spreading habit, dark bark, smaller and narrower leaves, fewer flowers, and more elongated drupe.

8. C. acutifolia.

Hook. fil., Journ. Linn. Socy., Bot., I., p. 128; Handbook N.Z. Flora, p. 114.

Kermadec Islands.—McGillivray (“Handbook”).

I am totally unacquainted with this species, and can add nothing to Sir J. D. Hooker's description. It seems to be allied on the one hand to C. grandifolia, and on the other to C. tenuifolia, but to be distinct from both. It is confined to the Kermadec Islands.

North Island.—Ruahine Mountains and other localities in Hawke's Bay, W. Colenso! Pirongia and Karioi Mountains, Mount Egmont Ranges, T.F.C. Forests between the Upper Wanganui and Taupo, T. Kirk!

I have already given a description of this species in the volume of the “Trans. N.Z. Inst.” quoted above, and do not

– 236 –

propose to repeat it here, as I have no fresh information to offer. The plant was first collected on the Ruahine Mountains by Mr. Colenso, many years ago. In the “Handbook” Sir Joseph Hooker referred it, with some doubt, to C. acutifolia. He now considers it to be distinct, and in this view is supported by Mr. N. E. Brown, who has pointed out to me that the venation of the leaves is entirely different in the two plants, and that C. acutifolia is quite glabrous, while C. tenuifolia is more or less pubescent on the stipules, young branchlets, and midrib and petioles. The inflorescence is probably quite distinct, but as at present the male flower of C. acutifolia and the young females of C. tenuifolia are alone known, it is difficult to form an opinion; although it seems likely that the inflorescence of C. tenuifolia will prove to be more compact than that of C. acutifolia.

10. C. arborea.
Kirk, Trans. N.Z. Inst., x., p. 420.

North Island.—Not uncommon from the North Cape southwards to the Waikato and Thames Rivers. Altitudinal range from sea-level to 1,000 feet.

A closely-branched round-headed tree, 20–30 feet high, with much of the habit and appearance of Myrsine urvillei. Trunk 6–14 inches in diameter, wood yellowish. Branchlets terete, puberulous towards the tips, bark greyish-brown. Leaves coriaceous, variable in size, 1–3 inches long, ½–1 ½ inches broad, ovate-spathulate or orbicular-spathulate, obtuse or retuse, suddenly narrowed into winged petioles ⅕–¾ inch long, yellowish-green above, often reddish below; veins closely reticulate; margins flat. Stipules short, triangular, finely ciliate when young. Flowers densely clustered in many-flowered glomerules or heads, which terminate the main branches as well as short axillary branchlets. Males: calyx narrow, deeply divided into 4–5 linear or linear-oblong ciliate lobes. Corolla campanulate, ⅕-inch long, deeply 4–5-lobed, lobes broad, acute. Stamens 4–5, filaments very long. Females: glomerules smaller, usually 4–12-flowered. Calyx-limb 4–5-toothed. Corolla smaller and narrower than in the males. Drupes closely packed, globose, or more rarely broadly oblong or obovoid, colourless and semi-transparent, ¼–⅓ inch in diameter.

The largest species of the genus, and very distinct from any other. The foliage is nearest to that of C. spathulata, but is much larger, and the petioles much shorter in proportion. The male flowers are very closely packed, forming large spherical glomerules, and these are placed at the terminations of the main branches, as well as on short axillary branchlets. The calyx of the male flowers is better developed, and has deeper divisions than in any other species.

North Island.—Abundant in forests from the North Cape to the Upper Waikato. Altitudinal range from sea-level to 1,000 feet.

A small shrub, rarely more than 5–6 feet in height. Branches few, slender and straggling, very young ones finely puberulous. Leaves rather distant, very variable in size, from ½ to 1 ½ inch long; blade orbicular or broadly oblong, obtuse, retuse, or emarginate, coriaceous, quite glabrous, suddenly narrowed into a narrow winged petiole which may be longer or shorter than the blade. Stipules triangular, cuspidate. Male flowers in 2–3-flowered axillary fascicles or solitary. Calyx deeply 4–5-lobed, invested at its base by an involucel composed of a pair of depauperated leaves and their stipules. Corolla campanulate, ⅕–¼ inch long, 4–5-lobed to the middle, lobes revolute. Stamens usually 4. Females usually solitary, but occasionally fascicled. Calyx-limb deeply 4-lobed, lobes erect, acute. Corolla rather smaller and narrower than in the males, funnel-shaped. Drupe globose, ⅕–⅓ inch diameter, black and shining when fully ripe.

Allied to C. arborea, from which it is easily separated by the small size, different habit, smaller foliage on longer petioles, fewer flowers, and by the larger black fruit. The leaves are often a bronzy colour, shining and polished on the upper surface.

North and South Islands.—Common in alluvial soils at moderate elevations, from the North Cape to Invercargill. Altitudinal range from sea-level to 1,500 feet.

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

A large laxly-branched shrub, 6–12 feet high. Branches long and slender, widely-spreading, irregularly and sparsely branched, the young ones densely pubescent or almost villous towards the tips; bark greyish-brown. Leaves in distant opposite pairs, ¼–1 inch long, usually orbicular, but varying to broadly-oblong or ovate-oblong, cuspidate or abruptly acute, rarely obtuse, very thin and membranous, more or less pubescent and ciliate, especially on the margins and on the veins below, veins finely reticulated; petioles short, villous. Flowers in axillary few or many-flowered fascicles, rarely solitary. Males: True calyx absent, but in its place one or two membranous involucels composed of a pair of depauperated leaves and their stipules. Corolla broadly campanulate, 1/10–⅛ inch

– 238 –

long, deeply 4-lobed. Stamens, 4. Female flowers smaller and narrower than the male. Calyx adnate to the ovary, invested at the base by involucels similar to those of the male; limb minute, truncate, or obscurely toothed. Corolla 1/10–1/12 inch, tubular, 3–4-lobed. Drupe variable in size, ⅛–¼ inch diameter, globose or broader than long, often didymous, red.

Distinguished from the following species by its spreading habit, large round leaves, usually densely aggregated flowers, and the smaller red drupe. From C. tenuicaulis it is removed by its coarser and more open habit, much larger and more membranous leaves, and by the colour of the drupe. C. rubra often closely approaches it in foliage; but the flowers are larger, and the drupe is oblong and yellow.

C. rotundifolia usually affects deep rich alluvial soils by the banks of rivers, and is particularly abundant in the swampy forests fringing the Northern Wairoa, Thames, Waikato, and other large streams in the North Island. The leaves are often deciduous, so that in spring the plant is usually quite bare. They are perhaps the most membranous of the genus. The fruit is frequently didymous, as described in the “Handbook,” but by no means invariably so.

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

An erect, closely branched, shrub or small tree, 6–15 feet in height. Branches slender, close, fastigiate, ultimate pubescent or almost villous with soft greyish hairs. Leaves in opposite pairs, ⅓–⅔ inch long, orbicular-spathulate, ovate-spathulate, or elliptic-spathulate, usually acute or apiculate, rather thin and membranous, flat, glabrous or nearly so above, usually pubescent on the veins below, suddenly narrowed into short hairy petioles; veins reticulated in large areoles. Flowers axillary, solitary or in few-flowered fascicles. Males: Usually 2–4 together, small, ⅛–⅙ inch. True calyx wanting, but one or two calycine involucels closely invest the base of the corolla. Corolla broadly campanulate, deeply 4–5-lobed. Females: solitary, or two together, rarely more, 1/10–⅛ inch long. Calyx-limb minute, truncate, or obscurely toothed. Corolla narrow, tubular. Drupe globose or broadly obovoid, ⅙–¼ inch diameter, reddish-black or nearly quite black.

Allied on one side to C. rotundifolia, and on the other to C. tenuicaulis. I have already pointed out its differences from the first of these, and C. tenuicaulis is at once separated by its

– 239 –

smaller size, spreading branches, dark-coloured bark, more glabrous leaves and branchlets, smaller and more coriaceous leaves, and perfectly black globose fruit.

North Island.—Not uncommon, especially in swampy forests. I have seen no South Island specimens. Altitudinal range from sea-level to 500 feet.

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

A densely and widely branched shrub, 4–8 feet high. Branches slender, bark plum-colour or dark purplish-brown; young branchlets finely and shortly puberulous. Leaves in opposite pairs, ¼–½ inch long, orbicular or ovate-spathulate, obtuse, somewhat coriaceous, flat, glabrous on both surfaces, narrowed into a broad flat petiole; veins reticulated in large areoles. Flowers axillary, solitary or more generally in 2–3-flowered fascicles. Males: No true calyx, but the usual calycine involucre present. Corolla broadly campanulate, ⅙–⅛ inch long, 4–5-lobed. Stamens, 4–5. Females: tubular, 1/7–⅛ inch long. Calyx - limb truncate. Corolla, 3–5-lobed. Drupe globose or depresso-globose, ⅛–⅕ inch diameter, shining black.

A distinct and well-marked species, which keeps its characters well in all stations. I have already pointed out its differences from C. areolata, which is its nearest ally. It is also closely related to C. rhamnoides, some broad-leaved forms of which come very close. But C. rhamnoides always has much more pubescent branches, and usually narrower and more pointed leaves, with very different venation, and the drupe is usually red.

North and South Islands.—Abundant throughout, from the North Cape to Stewart Island. Altitudinal range from sea-level to 3,000 feet.

A small, densely-branched bush, 2–6 feet high. Branches spreading, stiff, rigid, and often interlaced in exposed places; more slender and open in shaded. Bark greyish, or reddish-brown, fissured. Ultimate branches densely pubescent, with short stiff white hairs. Leaves very variable in shape and texture, from orbicular or broadly-ovate to narrow oblong, and in some varieties lanceolate or even linear leaves are mixed with the broader ones; rounded, retuse, or acute, narrowed into a very short petiole, from coriaceous to almost membranous;

glabrous or puberulous on the under-surface, ⅕–¾ inch long by ⅛–½ inch broad; veins reticulated and evident, except in the more coriaceous forms. Flowers axillary, or on short decurved lateral branchlets, solitary or in few-flowered fascicles. Males: True calyx wanting, but the usual cupuliform involucre composed of depauperated leaves and their stipules present. Corolla 1/10–⅛ inch long, campanulate, 4–5-lobed to below the middle; lobes often recurved. Stamens, 4–5. Females: smaller, 1/12–1/10 inch long. Calyx adnate to the ovary, its limb very short, truncate, or obsoletely toothed. Corolla tubular, 4-lobed to below the middle; lobes narrow, revolute. Drupe globose, usually bright red, occasionally black, ⅕ inch diameter.

Var. α. vera.—Leaves orbicular or broadly-ovate, obtuse, often coriaceous. C. rhamnoides, A. Cunn.

Var. β. divaricata.—Leaves broadly ovate, oblong-ovate or oblong, acute, rather thin. Narrower leaves, linear or lanceolate, often mixed with the broader ones. C. divaricata, A. Cunn.; but not C. divaricata, Hook. fil.

One of the most puzzling and variable species of the genus. Two main forms are distinguishable, as described above; but it must be borne in mind that numerous intermediates occur, which might be placed under either head. Var. α, with rounded obtuse leaves, I am informed by Mr. N. E. Brown, answers to Cunningham's type-specimens of C. rhamnoides, now preserved in the Kew Herbarium. In its extreme state it is stiff and rigid, with coriaceous leaves; but the branches often become longer and more slender, and the leaves thinner, narrower, and sub-acute. In this state it is C. concinna, Colenso, as I find from specimens kindly forwarded by Mr. Colenso himself. Var. β, Mr. Brown assures me, is identical with the true C. divaricata of A. Cunningham, a very different plant to the C. divaricata of the “Handbook;” and with this view Sir J. D. Hooker now concurs. It varies much in the shape of its leaves—from nearly round to ovate, trowel-shaped, or oblong; but as a rule, they are narrower, thinner, and more acute than in the preceding variety, into which, however, it passes by insensible gradations. Some common subvarieties of it are remarkable for having narrow lanceolate or linear leaves mixed with those of the ordinary form; these leaves being most plentiful on the younger branches. Mr Colenso has described this as a distinct species, under the name of C. heterophylla.

The flowers are very uniform in both varieties, and offer no distinctive characters of importance. They are perhaps the smallest in the genus, C. tenuicaulis, C. areolata, and C. rotundifolia being the nearest in this respect. The fruit is always globose, and usually a dark red—“port-wine” colour. Some varieties, however, have a crimson drupe, and in others the fruit becomes nearly black when decaying.

I am not acquainted with this species, and can therefore add nothing to Sir J. D. Hooker's description. The flowers and fruit are unknown, and I am not sure that the plant will not prove to be a variety of C. parviflora, mountain forms of which often have ciliate leaves.

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

A stout, erect, leafy shrub, 4–12 feet high. Branches stout or slender, much divided; branchlets often arranged in a horizontal plane, densely pubescent, sometimes quite shaggy; bark light grey. Leaves usually close set, fascicled on short lateral branchlets, ⅕–¾ inch long, 1/10–¼ inch broad, obovate, linear-obovate, or linear-oblong, obtuse and rounded at the tip, more rarely acute, coriaceous, flat or margins slightly recurved, glabrous, or the petiole and midrib slightly puberulous, or surfaces and margins ciliate with scattered soft hairs, gradually narrowed into short petioles, veins not conspicuous. Flowers solitary or 2–4 together. Males: True calyx wanting, but two minute 4-toothed involucels present at the base of the flower. Corolla 1/10–⅛ inch long, broadly campanulate, 4–5-partite almost to the base. Stamens, 4–5. Females: Calycine involucels present as in the males. Calyx-limb minutely 4–5-toothed. Corolla 1/12–1/10 inch, much narrower than in the males, and not so deeply cleft. Drupe globose, ⅕–¼ inch diameter, white or yellowish-white, translucent.

A well-marked and distinct species, which, though varying within certain limits, can always be distinguished from its allies by its leafy habit, pubescent branches, obovate or linear-obovate coriaceous leaves, and semi-transparent globose drupe. There are three main forms: the first, which may be considered the type of the species, is rather stout and closely branched, with moderately pubescent branches and obovate or linear-obovate coriaceous leaves, which are nearly glabrous. This form is found both in the lowlands and on the mountains. The second, which is common in many places on the mountains of Nelson

– 242 –

and Canterbury, has a much more slender habit, softer more pubescent branches, and rather broader much thinner leaves, which are usually ciliate on both surfaces and margins with soft hairs. This might be distinguished as var. pilosa. The third form is stiff and rigid, and very closely branched, with white bark and very small almost linear leaves. It also is montane, and occurs in several places in the Southern Alps, from Nelson to Otago.

A compact rigid bush, 6–12 feet high. Branches divaricating, excessively stiff and rigid, often interlacing. Bark reddish-brown or greyish-brown, rough, uneven, and fissured on the branches, smoother on the twigs. Ultimate branchlets glabrous or very finely puberulous. Leaves in pairs on opposite twigs, broadly oblong, ovate, or orbicular, rounded at the tip or retuse, suddenly narrowed into a very short puberulous petiole, flat, usually very thick and coriaceous, quite glabrous, often whitish below, ⅕–1 inch long, ⅙–¾ inch broad; veins usually concealed; margins thickened. Flowers terminating short lateral often leafless branchlets (and thus appearing axillary), solitary or more rarely 2–3 together. Males: True calyx wanting, but one or more involucels present, composed of depauperated leaves and their stipules. Corolla ⅙–¼ inch long, campanulate, 4-lobed to nearly the base, Stamens, 4. Females tubular, ⅛–⅙ inch long. Calyx adnate to the ovary, limb minute, truncate or obsoletely toothed. Drupe sub-globose or broadly oblong, ⅕–¼ inch diameter, dull yellow.

C. crassifolia, which is a distinct species, though closely allied to the following, was originally discovered by Mr. Colenso nearly 40 years ago, near the head of the Manukau Harbour. In the “Flora,” and also in the “Handbook,” Sir J. D. Hooker referred it, together with the three next species, to C. divaricata, A. Cunn. But Mr. N. E. Brown, who has lately carefully examined the whole of the Coprosmas in Cunningham's herbarium, has satisfied himself that the original type of C. divaricata is only a variety of C. rhamnoides, and that the four plants placed under it by Hooker are quite distinct, both from it and from one another. I understand that Sir Joseph Hooker now

– 243 –

accepts this view. As a species, C. crassifolia is best distinguished by the excessively stiff and rigid habit, almost glabrous branchlets, rounded thick and coriaceous leaves, and sub-globose yellow fruit. The next species is separated by its more slender habit, narrower spathulate leaves, and more oblong drupe; C. rubra by its larger thin orbicular leaves, and much larger oblong fruit; while C. virescens is at once removed by its slender habit and thin spathulate leaves.

North and South Islands.—Not uncommon throughout, in swampy forests.

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

A branching shrub or small tree, 5–15 feet high. Branches divaricating, stout or slender, open or much interlaced, glabrous or the very young twigs minutely pubescent; bark reddish-brown or plum colour. Leaves in opposite pairs on short lateral branchlets, ¼–¾ inch long, obovate or oblong-spathulate, coriaceous but variable in texture, dark-green above but paler below, quite glabrous, gradually narrowed into short petioles, veins not reticulated. Stipules triangular, glabrous. Flowers solitary, or in 2–4-flowered fascicles on short lateral branchlets. Males: True calyx wanting, but one or more cupuliform involucres closely investing the base of the corolla. Corolla broadly campanulate, ⅙–⅕ inch long, divided more than half-way down into 4–5 lobes. Stamens, 4–5. Females: Calyx adnate to the ovary, limb with 4–5 minute lobes. Corolla tubular, ⅙–1/7 inch long, deeply 3–5-lobed. Drupe oblong, yellow, ⅕–⅓ inch long.

This is one of the species included by Sir J. D. Hooker in C. divaricata of the “Flora” and “Handbook.” It is very near to the preceding, but the habit is not nearly so rigid, the leaves are narrower and not so coriaceous, and the fruit is larger and more oblong.

South Island.—Otago: near Dunedin; Otepopo; Palmerston South, D. Petrie!

An open or closely branched shrub, 5–12 feet high; branches slender, divaricating, ultimate ones pubescent; bark reddish-brown, smooth. Leaves varying from broadly-oblong to nearly orbicular, obtuse or sub-acute, glabrous or ciliolate, rather thin and membranous, narrowed into rather long ciliolate petioles, ¼–¾ inch long, ⅙–½ inch wide; veins reticulated. Flowers

sometimes solitary, but more generally in twos or threes on short lateral branchlets. Males: True calyx wanting, but one or more involucels closely invest the base of the corolla. Corolla ⅛–⅙ inch long, bell-shaped, 4-lobed. Stamens, 4. Females: Calyx adnate to the ovary, limb minute, 4–5-toothed. Corolla tubular, 4-partite. Drupe oblong, ¼–⅓ inch long, yellowish-white, translucent.

This species has much resemblance in foliage and habit to C. rotundifolia, but differs altogether in the flowers and fruit, which clearly place it in the same section as the two preceding plants. It seems to have been originally discovered by Mr Colenso in some locality in the North Island; but I have myself only seen Mr. Petrie's specimens, collected in Otago. Mr. N. E. Brown informs me, however, that Mr. Colenso's specimens exactly match Mr. Petrie's.

North Island.—Wairarapa Valley, Colenso. (No. 333 in Herb. Kew.)

South Island.—Otago: vicinity of Dunedin; Otepopo, etc., D. Petrie!

A compact glabrous shrub, 6–12 feet high. Branches numerous, slender, interlaced; bark greenish. Leaves in pairs on opposite twigs, spathulate, obtuse, glabrous, membranous, ⅕–⅓ inch long. Flowers solitary or in fascicles of two or three, terminating short lateral branchlets. Males: True calyx wanting, but the usual involucels formed of depauperated leaves and their stipules present. Corolla campanulate, deeply 4-lobed, ⅛ inch long. Females: Calyx-limb indistinctly 4-toothed. Corolla tubular, deeply 4-lobed, smaller than in the males. Drupe oblong, ¼ inch long, greenish-white or yellowish, translucent.

A very distinct species, but perhaps more closely allied to C. rubra than any other. I give the North Island locality on the authority of Mr. N. E. Brown, who informs me that Mr. Colenso's specimens agree very well with Otago ones collected by Mr. Petrie.

prostrate, tortuous and often interlaced, often zigzag, puberulous; bark yellowish-brown or dark-brown. Leaves in close or remote opposite pairs or fascicles, ⅕–⅗ inch long, 1/20 inch wide, very uniform in shape, narrow-linear, obtuse or sub-acute, sub-erect, rather rigid, veinless. Flowers apparently lateral, but in reality terminating minute arrested branchlets. Males: solitary, or in fascicles of 2–4. True calyx wanting, but one or two involucels present, composed of depauperated leaves and their stipules. Corolla broadly campanulate, ⅙ inch long, 4-lobed to below the middle. Stamens 4, rarely 5. Females always solitary, invested at the base by calycine involucres similar to those of the males. Calyx adnate to the ovary, limb minutely 4-toothed. Corolla 1/10 inch long, tubular, 4-lobed. Drupe globose, variable in size, ⅙–½ inch, pale blue.

Var. α.—Sand-dune form. Yellowish-green; branches long, slender, much and closely interlaced. Leaves close set, rather long and slender. Flowers usually solitary.

Var. β.—Inland and mountain form. Browner and darker; branches not so numerous, stouter and more rigid; leaves often short and stiff; male flowers usually fascicled.

The typical form of this species is a most abundant plant on sand-hills all round the New Zealand coast. It has long weak flexuous and tortuous branches, which are usually much and closely interlaced, thus forming a dense scrambling bush 1–5 feet high. Var. β is by no means common in the North Island, but is plentiful in the elevated central districts of the South Island. Extreme forms of it, with few prostrate branches, shorter and stiffer, much more remote leaves, look very different to the typical state; but intermediates are common. As a species, C. acerosa is at once distinguished by its peculiar habit, extremely narrow leaves, and sky-blue drupe.

A large branching shrub or small tree, 6–20 feet high. Branches widely divaricating, glabrous or puberulous at the tips; bark brown, or brownish-grey. Leaves opposite or in opposite pairs, usually rather distant, ¼–½ inch long, 1/12–⅛ inch wide, narrow linear-oblong, obtuse or sub-acute, rather coriaceous,

gradually narrowed into a very short petiole or quite sessile. Flowers terminating short lateral branchlets. Males: In fascicles of 3–4, or, more rarely, solitary. True calyx wanting; but a 4-toothed cupuliform involucre, composed of a pair of depauperated leaves and their stipules, invests the base of each fascicle and also of each flower. Corolla broadly campanulate, ⅙–⅕ inch long, deeply 5-lobed. Stamens, 4–5. Females solitary, much smaller than the males. Calyx adnate to the ovary, its limb 4-toothed or irregularly notched. Corolla tubular, 1/7–⅛ inch long, 3–4-lobed. Drupe variable in shape, oblong to globose, ⅓ inch long, blueish or blueish-black.

One of the largest of the species, being sometimes 20 feet high. It is allied on the one hand to C. cunninghamii, and on the other to C. linariifolia. From the first it differs in the more spreading habit, dark-coloured bark, smaller narrower leaves, and smaller and fewer flowers; from the last in the smaller, less acute, and more coriaceous leaves, in the stipules not being sheathing, in the inflorescence not being so distinctly terminal, and in the less-developed calyx of the female flowers. In the swampy kahikatea forests of the Thames and Waikato it is a most abundant plant, often forming the chief undergrowth over large areas. Though common in the South Island, it does not seem to attain the same size as in the North.

North Island.—Hilly and mountainous districts, and in the interior, as far north as the Thames Valley.

South Island.—Abundant throughout, especially in river valleys.

Altitudinal range, from sea-level to 2,500 feet.

A large branching shrub or small tree, 6–20 feet high. Branches slender, spreading; younger puberulous; bark dark-grey. Leaves all opposite, ½–1 ½ inch long, ⅛–¼ inch broad, linear or linear-lanceolate, more rarely oblong-lanceolate, acute or acuminate, flat, hardly coriaceous, suddenly narrowed into rather short slender petioles, blackish when dry, veins indistinct. Stipules glabrous or puberulous, upper ones connate for some length and sheathing the branch, margins usually ciliate. Flowers terminating leafy lateral branchlets. Males: in 3–5-flowered fascicles; each fascicle enclosed in one or two involucels composed of depauperated leaves and their stipules, and each flower with minute bracts at its base. True calyx wanting. Corolla broadly campanulate, ⅙–¼ inch long, divided about half-way down into 4–5 lobes; lobes usually revolute. Stamens, 4–5. Females: always solitary, seated within one or

– 247 –

two involucels similar to those of the male fascicles. Calyx limb with 4–5 large oblong erect lobes. Corolla ⅛ inch long, tubular. Drupe broadly oblong, ⅓ inch long, pale and semitransparent, with blueish streaks, crowned by the persistent calyx lobes.

The long sheathing stipules form a conspicuous, though variable, character for this species. In several respects it approaches C. propinqua and C. cunninghamii. I have already pointed out its differences from the first of these; and C. cunninghamii is easily separated by its larger paler foliage and more numerous flowers, the females of which have not the long calyx lobes of C. linariifolia. In exposed mountainous localities the habit becomes more compact, and the leaves shorter, broader, and more coriaceous, thus showing an approach to C. cuneata.

25. C. fœtidissima.

North Island.—Chiefly in hilly and mountainous localities, but not common to the north of the East Cape, although extending as far as the Thames Goldfields.

South Island.—Abundant throughout, especially in the interior.

Auckland and Campbell Islands.—Plentiful, Sir J. D. Hooker and others. Altitudinal range from sea-level to 5,000 feet.

Usually a slender, sparingly branched shrub or small tree, 6–15 feet high, but occasionally attaining a greater size, and in the Auckland Isles reaching 20 feet, with a trunk 1 ½ feet in diameter (Hook. fil., “Flora Antarctica”); intensely fœtid when bruised or while being dried. Branches slender, terete or tetragonous, glabrous or the very young ones minutely puberulous; bark pale. Leaves variable in size and shape, ½–2 inches long, ¼–¾ inches broad, usually oblong, but varying from linear-oblong or linear-obovate to rounded oblong or broad-ovate, obtuse, acute, or retuse, narrowed into rather long and slender petioles, rather membranous, or in some varieties coriaceous; margins flat; veins indistinct or few and diverging. Stipules short and broad, cuspidate, often puberulous, margins ciliate. Flowers sessile, terminating the branchlets. Males: solitary or two or three together; rather large, ⅓–⅔ inch long, often decurved. Calyx minute, cupular, irregularly 4-lobed, not always present, closely invested at its base by one or two cupuliform involucres composed of modified leaves and their stipules. Corolla campanulate, divided about half-way down

– 248 –

into 4–5, rarely 8–10, lobes. Stamens the same number as the lobes. Females: always solitary, erect, ¼–⅓ inch long. Calyx adnate to the ovary, limb truncate or obscurely toothed. Corolla tubular, 3–4-lobed. Drupe ⅓ inch long, oblong or ovoid, generally pale red in southern specimens, often white and transparent in the north.

C. fœtidissima forms a very considerable proportion of the undergrowth in the mountain forests of the South Island, but is not nearly so plentiful in the North. The horribly disagreeable odour of the leaves when bruised or drying, and the large terminal flowers, render it easy to recognise. The flowers are very frequently polygamous, and when so the calyx is always well-developed, which is not always the case in the normal male flowers. Its nearest ally is the following species.

26. C. colensoi.

North Island.—Thames goldfields, J. Adams! Te Aroha, Pirongia, and Karioi Mountains, altitude 1,500 to 3,000 feet, T.F.C. Mountains near Cook Strait, Colenso (“Handbook”).

South Island.—Stewart Island, D. Petrie!

A small, slender, open or closely-branched shrub, 4–8 feet high. Branches slender, terete, puberulous; bark pale, when old often loose and papery. Leaves yellowish-green, variable in size, ½–1 inch long, linear-oblong or linear-obovate to broad-oblong or obovate, obtuse, retuse, or emarginate, rarely acute, narrowed into rather slender petioles, rather membranous; margins flat or slightly recurved; veins usually indistinct. Flowers solitary, terminating the branchlets. Males: On very short decurved pedicels. True calyx wanting, but corolla seated in an involucel composed of a pair of depauperated leaves and their stipules. Corolla small, ⅛ inch long, broadly campanulate, 4-lobed. Stamens, 4–5. Females: On short decurved pedicels as in the males. Calyx-limb minute, 4–5-toothed. Corolla not seen. Drupe (unripe) oblong, ⅙ inch long.

It will be noticed that the above description, which is drawn up entirely from specimens collected by myself on Te Aroha and Pirongia mountains, hardly corresponds with that given in the “Handbook.” Sir Joseph Hooker, who has examined my specimens, is inclined to think that they represent a new species; but Mr. N. E. Brown places them under C. colensoi; stating, however, that they do not match the typical form of that plant. Not being acquainted with the true C. colensoi, I can hardly state what the differences are, for in a genus like Coprosma too much reliance cannot be placed on descriptions alone. However, the

– 249 –

most prudent course is to keep the two plants under the one name until further information is obtained. Mr. Petrie's specimens from Stewart Island have very much more coriaceous leaves, with different venation, and may be true C. colensoi; but as they have neither flowers nor fruit, it is difficult to pronounce on them.

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

A stout, densely-branched shrub, 2–10 feet high, in alpine situations becoming smaller and still more compact and rigid. Branches stout, usually densely leafy, the younger ones puberulous; bark dark-grey or brown. Leaves close set, often crowded on short lateral branchlets, variable in size, ⅕–¾ inch long, 1/10–¼ inch wide, obovate-lanceolate, linear-obovate, or oblong-obovate, more rarely cuneate-oblong, obtuse or sub-acute, patent or recurved, rigid and coriaceous, often concave above, almost veinless, margins often slightly recurved. Stipules short and broad, when young with the margins densely fimbriate or ciliate. Flowers solitary, terminating the branchlets, sessile. Males: True calyx wanting, but the base of the corolla invested by one or two involucels. Corolla ¼–⅓ inch long, broad campanulate, tube short and narrow, lobes widely spreading, 4 or 5. Females: Calyx-limb 4-lobed, lobes rather long, blunt, unequal. Corolla shorter and narrower than the males, ⅕–¼ inch long, 4-lobed to the middle or below. Drupe globose, ⅛–⅙ inch diameter.

One of the most variable species of the genus, but well-marked off from any other by its dense and leafy habit, broad fimbriate stipules, coriaceous recurved linear-obovate or cuneate leaves, which are often concave above, and by the rather large terminal flowers. It varies exceedingly in size, and when high up on the mountains is often reduced to a bush little more than a foot in height, the leaves, etc., being correspondingly reduced. It is exceedingly abundant on the slopes of Mount Egmont, near the upper limit of the forest, forming a leafy shrub 12 feet in height, or even more, and with leaves sometimes ¾ inch in length. Further up the mountain it forms a dense scrub, 2–3 feet high, with close and matted branches. North Island specimens appear to have stouter branches and broader leaves than the majority of those from the South Island.

North Island.—“Tops of the Ruahine Mountains, Colenso” (“Handbook”).

I am either unacquainted with this species, or have not identified it, and can consequently add nothing to Sir Joseph Hooker's description. It appears to differ from C. cuneata in its slender habit, and narrower thin and flat leaves.

South Island.—Mount Arthur plateau, Nelson, altitude 4,000 to 5,000 feet, T.F.C.

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

A low, densely-branched, often prostrate bush, 2–4 feet high. Branches leafy, trailing or prostrate, puberulous; bark greyish. Leaves opposite or in opposite fascicles, linear-lanceolate, about ⅕ inch long by 1/15 inch wide, acute or obtuse, rigid and coriaceous, veinless, somewhat concave, glabrous or with a few scattered hairs towards the margins, sub-erect patent or recurved, narrowed into very short stout petioles. Stipules short and broad, ciliate on the margins. Flowers terminating the branchlets, solitary, sessile. Males: True calyx wanting, but the usual calycine involucels present. Corolla 1/10–⅛ inch long, campanulate, deeply 4-lobed. Stamens, 4. Females: Invested by involucels similar to those of the males. Calyx-limb 3–4-toothed. Corolla 1/10 inch, deeply 4-lobed. Styles 2, short and stout. Drupe globose, ⅛ inch diameter, yellowish-red.

The plant described above is not uncommon on the Mount Arthur plateau, Nelson; and is, I think, identical with Colenso's C. depressa. It is principally separated from C. cuneata by its smaller size, more slender and prostrate habit, and by the smaller narrower leaves. Small forms of C. cuneata, however, approach very close to it, and it may prove to be a variety only.

– 251 –

A small alpine creeping species. Branches glabrous, long or short, 4–18 inches, often closely matted together, prostrate and rooting, bark pale or dark grey. Leaves usually close-set, but sometimes distant, sub-erect or patent, bright-green, coriaceous and somewhat rigid, ⅛–⅓ inch long, linear-oblong or linear-obovate to broad oblong or broad obovate, acute or obtuse, narrowed into very short broad petioles or nearly sessile; veinless. Stipules short and broad, obtuse, often ciliate. Flowers greenish-white, solitary, terminating short erect branchlets. Males: Large for the size of the plant, ⅓–1 inch long. Calyx present, small, cupular 4–8-toothed. Corolla tubular, often curved, shortly 4–8-toothed. Stamens, 4–8; filaments often twice as long as the corolla; anthers narrow, large. Females: Much smaller, seldom more than ⅓ inch long. Calyx-limb 4–8-toothed. Corolla tubular, 4–8-lobed to about one-third way down. Styles 2–4 or 5. Drupe globose, ¼–⅓ inch diameter, red; nuts, 2–4.

C. repens is easily distinguished from all the New Zealand species of Coprosma, except C. petriei, by its small size and creeping and prostrate habit. From C. petriei it is separated by the rather larger and broader always glabrous leaves, much larger tubular male flowers, and red globose drupe. It will be noticed that I have treated C. pumila, Hook. fil., as a synonym of C. repens. This I have done on the authority of Mr. N. E. Brown, of the Kew Herbarium, who informs me that, after a careful examination of the specimens on which the species was based, he can find no sufficient characters to separate it from C. repens. As I understand that Sir Joseph Hooker accepts this view, and as I have had no opportunity of examining the types, I am inclined to follow it also. There is a probability, however, that a closely-allied species exists, differing from C. repens to a certain extent in habit, in floral characters, and in the much larger purple drupe. I understand that Mr. Kirk considers this to be the true C. pumila; but this view is not supported by the description given in the “Handbook,” where the fruit is described as orange-yellow. It does not follow that, because a species allied to C. repens probably exists, it must of necessity answer to Hooker's C. pumila.

glabrous or puberulous. Leaves close-set or distant, erectopatent, 1/10–¼ inch long, linear-oblong or linear-obovate, acute or obtuse, narrowed into short petioles or sessile, veinless, glabrous, or margins and both surfaces sprinkled over with short white hairs. Flowers solitary, terminating short erect branchlets. Males: ⅕–⅓ inch long. True calyx wanting; but the usual calycine involucels investing the base of the corolla. Corolla tubular at the base, campanulate above, 4-lobed. Females: smaller, 1/10 inch long. Calyx-limb irregularly toothed. Corolla short, broadly tubular, 4-lobed to below the middle. Drupe globose, ⅙ inch diameter; red in Mount Arthur specimens, but blueish in Otago, according to Mr. Petrie.

Apparently a very distinct little plant, at once separated from C. repens by the shape of the male corolla.

Plate XIX.

I.—General, or Common.

Not being acquainted with the living botany of the South Island, my remarks will be necessarily confined to the tree-ferns of the North Island: at the same time I think that many of those plants are nearly as common there as they are here.

Tree-ferns are general throughout the North Island, in forests, on the edges of woods, and on the banks of streams; they are found in dry hilly woods as well as in the low wet ones, but are more numerous and gregarious in the latter. Mostly growing singly, scattered among the trees of the forest; not unfrequently, however, in small clumps, especially on low alluvial flats or tongues of land in the woods bounded on two sides by watercourses; and, more rarely, in tolerably large and continuous groves in wet situations between hills, in forests.

The number of species at present known of tree-ferns is 11.* These are classed under 4 genera, viz., Cyathea, Hemitelia, Dicksonia, and Alsophila. Of those 4 genera, Cyathea has 5, and Dicksonia 4, species; Hemitelia possesses 2, and Alsophila

[Footnote] * Of these, 7 are described in the “Handbook, Flora of New Zealand,” and “Synopsis Filicum;” and 4 (since discovered) in “Trans. N.Z. Inst.,” vols. xi., xv., and xviii.

– 253 –

but 1. This last fern is much more rare, and affects a higher altitude than the others, having been only met with by me in the Fagus forests of the Ruahine mountain range, 2,000 feet altitude and upwards. Of all the genera, Dicksonia is the most common, especially in the southern parts of this island. Most of the species are endemic; one or two of them are stated to inhabit Tasmania and Australia; and the most striking and distinct one of all, Cyathea dealbata (the “Silver-tree-fern”), is said to be found in Lord Howe Islands, in latitude 32° S., between the North Cape of New Zealand and Sydney.

They are usually of a single stem, erect and columnar, and devoid of branches, with a spreading crown of large regular and elegant palm-like fronds, gracefully radiating from the top and forming a living circle. In some species, especially of Cyathea, (e.g., C. medullaris, Forst., and C. polyneuron, Col.), their fronds attain to a very large size; I have measured them 15–20 feet long and proportionately broad; when large they are gracefully arched; when small are often extended, and nearly plane. Sometimes, however, their stems are inclined, others are gradually curved, and others drooping—particularly when springing from the sides of a declivity or ravine, or when over-hanging a stream. They are of various heights and thicknesses, some species being taller and slenderer than others, ranging in height from 6 to 45 feet, and in thickness from 4 inches to 2 feet: only one species, however, (Dicksonia fibrosa, Col.), attains to the maximum thickness, while Dicksonia squarrosa, D. gracilis, and most of the species of Cyathea and of Hemitelia are among the tallest. Our single known species of Alsophila is the shortest, and is sometimes stemless.

They are very rarely met with bearing branches; I have, however, seen a few 2-branched, and two specimens 3-branched; and occasionally 2, 3, or 4 springing closely together from the ground, as if fascicled below at the base.

Sometimes their trunks are quite clean, and devoid of epiphytal vegetation; more commonly, however, they are clothed with a dense mass of epiphytes; the stems of some species, when clear, often present a neat appearance throughout, from the regularity of the broken bases of their stipites, which add much to their beauty; while others show no such remains, but, instead, a dense and everincreasing mass of hardened surface rootlets, which generally assume a pretty even appearance, growing circularly around the stem after the manner of bark, but now and then shooting downwards irregularly in long shaggy masses; this last feature, however, generally pertains to the lower side of curved stems. And while on some trunks there are few or no withered fronds hanging from above beneath the living crown of the fern-tree, others are completely enveloped in their old pendulous fronds,

– 254 –

the growth of many years, presenting a curious bushy spectacle, appearing in the quiet sheltered recesses of the ancient forests as if no disturbance had ever there taken place, for not one old frond had fallen from above! As a natural consequence, in such cases the stems underneath are clean and free from epiphytes.

The epiphytal vegetation common to the stems of the tree-ferns is in some respects peculiar and worthy of notice. For, while such is mainly composed of some of our smallest and most delicate ferns, (of Hepaticæ, and one or two species of mosses, and not unfrequently a small Astelia), some of the larger trees of the forest are often seen springing from their stems; these not unfrequently flourish in their peculiar situations, and sometimes grow to a large size, lofty, overtopping the fern-tree itself, and sometimes, though rarely, killing it by its close embrace; more usually, both seem to flourish and enjoy their curious reciprocal attachment. The trees that are commonly found so combined with the fern-tree are Weinmannia (sps.), and Panax arborea, and Ackama rosæfolia in the forests at the North, the peculiar locality of this genus.

The ferns that often clothe and completely hide the trunks of the tree-ferns comprise the smaller species of Hymenophyllum, as H. nitens, H. tunbridgense (and its varieties), and H. rarum; also, Trichomanes venosum, and its near ally T. venustula; indeed, such may truly be called the proper home of these two Trichomanes, as well as of Hymenophyllum tunbridgense, for nowhere else are these pretty little ferns to be found growing so luxuriantly. It is a beautiful object to contemplate the whole stem of a large tree-fern so dressed and decorated by Nature! often extending completely and closely around the trunk, and that for several feet; their little elegant glistening light-green fronds, so very regular, too, in their manner of pendulous growth, overlapping each other and imbricating like scales. Here is also the home of that highly curious fern Tmesipteris, never found growing on the earth, and rarely found on any other plant; and very recently a small and new species* of the closely-allied genus Lycopodium has been detected growing thereon; while a small elegant moss, Hymenodon piliferus, (the only New Zealand species of that genus), is sure to be found deeply ensconced between the numerous dead stipites, and growing freely in its dry abode. Two or three species of delicate small frondose Hepaticæ (e.g., Symphyogyna sub-simplex, S. brevicaulis, S. simplex, Podomitrium, Phyllanthus, etc.), are also at home there, snugly nestling deep in the crevices of the stems, from which it is a difficult matter to dislodge them without breaking; while some of the larger Hepaticæ, as the dendroid Plagiochilæ, areoften found growing

[Footnote] * A full description of this little novelty has been prepared, and will be iven in a following paper.

– 255 –

luxuriantly upon their trunks, completely enwrapping them below, especially in low, wet, shaded woods.

Other and larger ferns than those mentioned are not unfrequently to be met with, depending from the trunks of the tree-ferns, as Hymenophyllum dilatatum, H. demissum, H. multifidum, Asplenium falcatum, A. flaccidum, and Polypodium (species); also Lycopodium varium; but then these are much more common and plentiful elsewhere, both on trees and on the ground.

II.—Particular, or Uncommon.

Under this heading I wish to state what I have more recently seen, which, indeed, is the main cause of my writing this paper. During the last three to four years I have noticed some extraordinary things pertaining to the tree-ferns.

1. As to their great number in one spot, and their manner of growth there.—In certain unfrequented localities in the dense forest of the Seventy-mile Bush, which I explored at different times, I suddenly came upon two or three groves of tree-ferns: one in particular I will attempt to describe. On a flat in the heart of the forest, in a deep hollow lying between steep hills, the bottom of which for want of drainage was very wet and uneven, and contained much deep vegetable mud and water even in the driest summer season, I found a large and continuous grove or thicket of very tall tree-ferns, chiefly Dicksonia squarrosa, and D. fibrosa, with a few of Cyathea dealbata intermixed, with but few forest trees and shrubs growing scattered among them. I suppose they occupied about 3 roods of ground, and I estimated their number to be from 800 to 1,000. They were all lofty, from 25 to 35 feet high, and in many places growing so close together that it was impossible to force one's way through them. Their trunks were most profusely covered with the usual epiphytal ferns (those smaller ones already mentioned). Conspicuous, however, among them, was that very rare fern in these parts, Hymenophyllum subtilissimum, Kunze, (H. frankliniarum, Col.,*) which literally clothed their trunks from top to base, intermixing below in the more humid spots with a fine dendroid Plagiochila (sp. nov.) of most luxuriant growth. The ground, too, with rotting logs and stumps below, was densely covered with various fine Hepaticæ of several genera, (as Plagiochila, Gottschea, Lepidozia, Mastigobryum, Podomitrium, Symphyogyna, etc.), while here and there among them were several lovely and rare mosses of the genera Hypopterygium, Cyatrophorum, and Hookeria; and on the higher and drier stumps and mounds grew graceful undisturbed cushions of Leucobryum candidum, plentifully in fruit, rather a rare occurrence.

[Footnote] * Hymenophyllum æruginosum, Carm., of “Handbook N.Z. Flora.”

[Footnote] † The description of this fine species will be given in a following paper.

– 256 –

A few of those tree-ferns were 2-branched; one, I noticed bearing three branches; all of the branches were at some height from the ground, and rose just as high as the parent stock. Several of those tree-ferns grew in little clumps of 3, 4, or 5, arising from small mounds 2 feet high or so, with deep watery muddy holes between them; their stems were very close together, and appeared as if fascicled or springing from one root-stock below; while above they not unfrequently diverged from the perpendicular.

Familiar as I have long been with our New Zealand forests and their denizens, I gazed with astonishment in this deep and secluded grove of tree-ferns! for I had never before witnessed such a grand display of them; neither had I seen for upwards of 40 years* this pretty species of soft silky Hymenophyllum that was here so exceedingly common. Very certain I am that it does not grow in those several and many scattered parts of that same extensive forest which I have so frequently visited during these last 10–12 years.

From this wet wood I brought away several fine Hepaticæ; particularly that superb Gottschea, G. dichotoma, Col., the largest known New Zealand species. This fine plant (which I have only detected in this locality), completely and thickly covered a large old stump, hanging gracefully down around its top, reminding one of a rich-looking fringed circular cushion or hassock. The ground or mud in many places was thickly covered with long irregular patches of an erect species of Symphyogyna, which I believe to be new. This genus is mostly gregarious in small lots, but I never before saw it growing in such profusion, and so very compact and large, somewhat resembling beds of curled cress or parsley. Places and spots of botanical beauty or-novelty, however, (like all other things), have their drawbacks or opposites: the worst feature here was the very bad footing, causing much tumbling about and splashing and sinking, between slippery and hidden rotting roots and branches, into deep black vegetable mud up to one's knees; and then there was the haunting fear of some accident happening, through which I should not be able to get out of this tangled labyrinth; and, as a matter of course, in that distant and unfrequented spot, should not be easily or early found, if ever found at all!

2. As to the very peculiar growth of some tree-ferns, caused by

their own epiphytes.—Some novel instances of this nature I have occasionally met with, a few of them being very strange.

(1.) I have already said tree-ferns are often found with young plants of Weinmannia (sps.), and of Panax arborea, springing from their stocks at some distance above the ground. These trees also grow to a considerable size—of 3, 5 and 7 feet, and are well-branched and flourishing, although their rootsdo not reach down to the earth. A few of them, however, of a much larger size, 14–16 feet high, that I have seen and examined, send down their trunks (I can hardly term them roots) from the place where they had sprung from seed on the stock of the fern-tree into the ground, (sometimes in two or three branches or ramifications), closely adhering to the fern-tree and partly intertwining its stem.

(2.) In a dry wood on the bank of the River Mangatawhainui I saw several specimens of this nature. One aged fern-tree had its base completely surrounded at the surface of the ground by a large Weinmannia racemosa, that had originally sprung from its stock, which also adhered to it above on one side for several feet. Another fern-tree had a Weinmannia embracing it on the one side, and on the opposite side a Panax arborea, (this latter very largely and closely), and both trees had originally sprung from the trunk of the fern-tree, and thence descended to the earth. I noticed one tree-fern in particular, that was wholly separated below from the earth, having its caudex closely hugged for 2–3 feet by a large branching Panax arborea, whose branches or divided stem (I cannot call them roots) descended from the original point of first growth above in the stock of the fern-tree, and enwrapping it at intervals had held it fast, wholly immovable, as if the two trees had coalesced into one. This was on the side of a dry hill, and the rains, etc., in past years, had completely washed away the soil and small vegetation from beneath and around the base of the fern-tree; the fern, however (a Cyathea dealbata), was of a large size and most luxuriant growth. I had detected two or three instances of that nature before, but those fern-trees were only partially severed from the earth at their bases, while this one was wholly separate, and from its appearance had been so for many years, as no fresh rootlets were emitted there.

(3.) Strange, however, as that instance may appear, I have still a more curious anomaly to mention, which, as far as I know, is quite unique. Four years ago, while botanising in the high and dry woods near Matamau, I came upon a fine tree-fern (Cyathea dealbata), whose caudex below was almost wholly surrounded by its former epiphytal foster-child—a stout spreading specimen of Panax arborea, from which, or out of which! the fern-tree luxuriously grew, as if it were springing from a large vase! On the one side (or, rather, speaking correctly, on three

sides), the fern-tree was wholly enclosed; and this was all the more plainly to be seen, from the fact of the trunk of the Panax being bare of epiphytal vegetation, so that its light-coloured and clean bark showed in strong relief against that of the darker fern-tree in the few narrow interstices on the one side where it still slightly appeared. Another great curiosity was the entire unbroken appearance of the Panax on the one side of the fern-tree, which was completely covered by it; there was no trace discernible of any cicatrices or joinings in its bark, which was even. The tree, or pair so strangely conjoined, stood in a small glade or open space among the trees of the forest that were densely thick around, which circumstance, together with the dark-green foliage of the very large leaves and sprays of the Panax, above and around the delicate pure white fronds of the fern (viewed from beneath them and looking up), with the blue sky here and there in the background seen through their branches, caused the two trees to be seen to a great advantage. The tout ensemble was both unusual and charming, and served to bring to mind portions of Ovid's metamorphoses of trees.

Another pleasing thought arose from the consideration of this tree (Panax), in its so clasping and sending out and down its root-like branches, (which it never does when growing in the earth in its native woods), thus showing its real natural affinity in latent habit to those other genera of that same natural order in which it is placed, (e.g., Hedera, Gunnera, etc.), which so largely and constantly grow and adhere by their climbing root-lets; and yet the ivy (Hedera helix) sometimes grows as a standard.

I visited that spot on several occasions during two years, and always with feelings of admiration; and was so much surprised and pleased with my “find,” that on two of those visits, having taken my portfolio with me, I attempted to take a drawing of it; (in one of those times, however, being caught in heavy rain!) but, owing to the loss of drawing and writing power in my thumb, I made a poor job of it. Still, such as it is, and unfinished, I bring it before you, as by it you may be the better able to know somewhat of the relative sizes and appearances of the two curiously-entwined and coalesced plants.

I took accurate measurements of this botanical phenomenon, and the following is the result:—

1.

Height of caudex of Cyathea from the ground to the springing of its living fronds, 7ft. 6in.

2.

Height of Panax, about 18ft.

3.

Girth of both, taken together at base, 6ft.

4.

At 5ft. 3in. from the ground the Panax tree forked into two stout, erect main branches.

5.

Girth of both plants under the forking of the Panax, 5ft. 3in.

– 259 –
6.

Girth of main branch of Panax, 2ft. 10in.; of the other, 2ft. 3in.

7.

Girth of Cyathea, immediately under its crown of fronds, 5ft.

8.

Breadth of the narrow interstices of the stem of the fern-tree not yet covered by the Panax: at the base, 2in.; above, in the widest part, 3in.

9.

The fronds of the fern extended about 9ft. each way, forming a flattish arch.

10.

The lower horizontal branches of the Panax extended nearly equal with the fronds of the fern.

11.

The trunk of the Panax below was quite bare of epiphytal vegetation (only a small young creeping plant of Metrosideros scandens just climbing up at one corner), but large fronds of Polypodium billardieri and other ferns hung pendulous from between the two upright limbs of the Panax and the Cyathea.

12.

The longitudinal edges of the root-like descending lower limbs of the Panax showed exactly the appearance of the back of a healthy tree from which a limb has been clean cut off, growing-in with thick round advancing margins over the wound.

[Read before the Hawke's Bay Philosophical Institute, 11th October, 1886.]

Class I.—Dicotyledons.
Order I.*Ranunculaceæ.

Genus 1. Clematis, Linn.

1. C. aphylla, sp. nov.

A slender prostrate trailing plant. Stems 2–4 feet (or more) long, cylindrical, very narrow, 1 line diameter, green, glabrous, striate, few-branched; nodes at pretty regular distances, 5–6 inches apart. Leaves, O. Peduncles slender, hairy,

[Footnote] * The numbers in this paper attached to both orders and genera are those of “The Handbook of the New Zealand Flora.”

– 260 –

1 ½–2 inches long, a 2-lobed connate densely hairy bract at base, and another about the middle; hairs brown. Flowers hermaphrodite, axillary, opposite, single, small, greenish with a brown tinge, about 1 inch diameter, (?) monœcious; sepals 4, broadly-lanceolate, or sub-ovate lanceolate, sub-acute, 6 lines long, conniving, very silky on both surfaces, many nerved (6–7), nerves branching; margins uneven at tips, sub-ciliate. Stamens 10, sub-lanceolate-linear, rather broad, green; anthers long, linear, very narrow, with a minute blunt connective; achenes (immature) slightly silky; styles shorter than sepals, green, silky, tips recurved.

Hab. Trailing and hanging down on cliffy spots, Puketapu, near Napier; 1885–6: Mr. H. Hill.

Obs. This is a very peculiar plant, widely differing from the other New Zealand species of this genus, as well as from those of Australia and Tasmania. We have now known it for two years, and it always presents the same appearance—long trailing slender green stems, no leaves, and single 4-sepaled hermaphrodite flowers. I have examined several specimens, and they do not vary; only one of them had three flowers, all on separate peduncles and with separate basal bracts springing from one axil, as if fascicled but distinct. It would have been described by me last year, but I had a suspicion that it might prove to be identical with C. fœtida, var. β depauperata, or a variety of it; which, however, I do not now believe, after re-examining several fresh specimens.

Order IV.—Violarieæ.

Genus 2. Melicytus, Forst.

1. M. microphyllus, sp. nov.

A tall, slender shrub or small tree, 12–15 feet high, trunk 5 inches diameter; bark pale drab-brown, much and densely mossed, etc.; branches long, slender; branchlets many, sub-erect, pubescent. Leaves small, numerous, sub-coriaceous, glabrous, scattered, single and sub-fascicled 2–4 together, 1–3 (rarely 4) lines long, oblong-orbicular, sub-panduriform, and orbicular, reticulately and coarsely veined, green, margin purple, sinuate, acutely toothed with a small red curved tooth at extremity of each primary vein (usually 6 on a leaf); apex very broad, obtuse, and retuse, with a small central tooth; base tapering; petiole short, under 1 line long, slightly puberulous, with small scarious stipellæ at base. Flowers pretty numerous, rather small, orbicular, 1 ½–2 lines diameter, axillary and lateral, solitary, sometimes in pairs; peduncle longer than petiole, 1–1 ½ lines long, stout, slightly puberulous, bracteate; bracts generally above, rarely below. Calyx purple, glabrous, veined,

– 261 –

acutely 5-lobed, lobes spreading, tips sub-laciniate. Petals (sometimes 6) sessile, rather large, spreading, broadly ovate and sub-orbicular, with a single middle vein, pale, streaked and tipped with purple; tips slightly erose or sub-laciniate, sub-apiculate and recurved. Anthers (sometimes 6) sessile, large, gibbous, didymous, with a large thickish clavate connective a little higher than the anther. Stigma very small, sessile, conical, slightly sub-trifid. Fruit O.

Hab. Forests, banks of River Mangatawhainui, near Norse-wood, County of Waipawa; 1886: W.C.

Obs. This species certainly approaches very near to M. micranthus, Hook. fil., but it differs in several characters, as well as in its much larger size, with larger flowers and smaller leaves. I suspect this plant is diœcious, and the above description of the male flowers only. I first detected it in full flower in March; and on again visiting the same tree in May (end of month), hoping to obtain fruit, there was not a berry to be found, but the plant still bearing a few flowers. I have for many years noticed young plants of upright growth, and 5–7 feet high, in those woods, but always in leaf only, although frequently diligently examined by me. This tree is the only one I found bearing flowers.

Order VI.—Caryophylleæ.

Genus 3. Colobanthus, Bartling.

1. C. repens, sp. nov.

A small quite glabrous low creeping perennial plant, about ¾-inch high, forming a short densely matted turf; branches 3–4 inches long, procumbent, rooting at nodes. Leaves about ½ inch long, narrow-linear, subulate, sub-acute with acicular tips, thickish, not rigid, nerveless, green, shining, spreading, recurved; the lower dilated and largely membranous at base, the upper connate; minutely ciliate on lower margins; ciliæ fugacious. Scapes solitary, axillary, slender, erect, straight, 6–7 lines long, longer than leaves. Perianth 1 line long; sepals 4, broadly ovate, obtuse, shorter than capsule, green, concave, 3-nerved, slightly margined; margins translucent. Stigmas 4, strongly recurved, stout, papillose, brown. Capsule pale, longer than perianth, valves obtuse, tips rounded. Seeds light-brown, sub-triangular-orbicular, finely granulate.

Hab. On low alluvial banks, (growing intermixed with Pratia and Hydrocotyle), sides of River Mangatawhainui, near Norsewood, County of Waipawa; 1886: W.C.

Obs. A species possessing affinity with C. quitensis and C. billardieri (both New Zealand plants), but differing in habit and in several particulars.

– 262 –

Order XXXIII.—Umbelliferæ.

Genus 1. Hydrocotyle, Linn.

1. H. involucrata, sp. nov.

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

Plant procumbent, trailing. Stems 10–00 inches long, slender, glabrous, with a few weak scattered hairs; nodes 3–5 inches apart, each having a large clasping sub-orbicular-reniform stipule, the margins irregularly and minutely lobed and toothed, pellucid and highly cellular; cells large oblong. Leaves few, distant, membranous, somewhat roughish from raised bases of hairs, dull light-green, reniform, 1–1 ¼ inches broad, 6-lobed; lobes rounded, cut into one-fifth of leaf, their sinuses overlapping; margins irregular, sub-crenate-toothed; basal sinus very broad, the margins more acutely toothed; 8-veined, veins (and margins) light-reddish; hairy on both sides, but much more so below; hairs short, thickish, acute, white; petioles very long 3–5 inches, slender, weak, hairy below with long scattered weak 1-nerved reflexed hairs that increase in density upwards towards the apex. Peduncle one-third length of leaves, 1–1 ½ inches long, hairy. Umbels 8–14-flowered, in a compact sub-globular head. Involucre in 2 rows, composed of 10–12 convex incurved membranous leaflets with darkish-brown centres and pellucid margins; the outer, ovate, margins laciniate; the inner, linear-oblong, margins entire. Flowers rather large, pale-brown, pedicelled; pedicels erect, glabrous, 1 line long, with sometimes a small bracteole near the apex; petals valvate, broadly ovate, 1-nerved; tips sub-acute and obtuse, their margins finely crenulate-toothed (sub lente); stamens largely exserted, curved; anthers orbicular (a little broader than long), pale; styles stout, long, at first converging, afterwards very divergent. Fruit rather large, pale-greenish-brown, nearly orbicular, 1/10 inch broad, straight below, apex very slightly notched, flat, glabrous, shining, thickest at centre, intermediate ribs obscure, dorsal edge of carpels obtuse; seed narrow, linear-ovate, obtuse.

Hab. Low wet spots in forests, hilly country north of Napier, County of Wairoa; 1886: Mr. A. Hamilton.

Obs. A species having some affinity with H. novæ-zealandiæ, D.C., H. pterocarpa, F. Müell., and H. vagans, Hook. fil., (an Australian species), but differing from them (and from all the species described in the “Handbook, Flora N.Z.,”) by its involucral leaflets; in this respect, however, it approaches a few of the Australian species; also, the two newly-described species (mihi), H. colorata and H. alsophila,* in their floral bracteoles.

Order XXXVIII.—Rubiaceæ.

Genus 1. Coprosma, Forst.

1. C. autumnalis, sp. nov.

Plant, a small tree, or tall slender shrub, erect, 12–16 feet high, few-branched; trunk 3–5 inches diameter, clear of branches; branches distant, slender, long, drooping; bark thin, light-brown, with a fine scaly silvery-white epidermis; inner bark orange. Leaves large, membranous, not numerous, sub-terminal on branchlets, 1–1 ¼ inches apart, broadly lanceolate, 5–6 ½ inches long, 2 ½–3 ½ inches broad, acute, narrowly margined; margins sub-crenulate, especially towards tips; dark-green and shining above, much paler below, coarsely reticulated on both sides, deeply and largely foveolate in main axils; foveolæ ciliate; petioles stout, 1–1 ¼ inches; stipules large, sub-conical, cuspidate, hard, black, glossy. Peduncles axillary; (fem.) stout, sub-compressed, 1–1 ½ inches long, trichotomously branched; the 3 sub-peduncles fascicled, each ½ inch long; stipules at base 4-fid. Flowers—Male: Peduncles ½–¾ inch long, rather slender, 3- sometimes 5-branched, with a pair of small leafy bracts at base; sub-peduncles 4–5 lines long; heads of flowers large, densely compact, outer heads each 6–9, middle head 8–16 flowers; calyx small, cup-shaped, with 5–6 stoutish teeth; corolla campanulate, 3 lines long, 5-lobed; lobes rather large, one-third length of corolla, sub-acute, erect; anthers 6 (sometimes in outer flowers 5), large, stout, 2 lines long, linear, obtuse, purple-tipped, base much hastate, very pendulous; stamens ½ inch long, filiform, minutely papillose. Female: outer 2 sub-peduncles, each 3–4, and the central one 6–9 flowers; involucral or floral bract large, with 6–8 coarse teeth; calyx greenish, purple spotted, sub-urceolate, with 5–6 stout teeth; teeth conniving; corolla pale green, infundibuliform, 2 ½ lines long, 5-sometimes 6-lobed; lobes large, obtuse, spreading, sub-recurved; stigmas 2, ½ inch long, stout, divergent, much crumpled, very pubescent. Fruit 3–4, sometimes 5–6 (rarely 9), drupæ, clustered, sessile, broadly elliptic, 4–4 ½ lines long, bright red (red-currant-colour), very glossy. Seeds large, oval, sub-acute, 3 ½ lines long, 2 lines broad, convex on the outside, flat within, white, somewhat silvery.

Hab. Forests near Norsewood, County of Waipawa; 1881–6: W.C. Flowering in May and June.

Obs. I. The near affinity of this fine species is with C. grandifolia, Hook. fil., from which, however, it differs in several characters: as the larger number of its flowers in heads, both male and female, in its corollas, anthers, and large elliptic fruits. It is a curious and novel sight to see in the autumn the female plant loaded with both ripe fruit and the

– 264 –

new opening flowers of the coming spring-summer season; at such time, too, the ground is covered with the glossy red fruits, which are also juicy and sweet. The pleasing phenomenon served to remind me of the poet Thomson's ideal of vegetation in the beginning—the Golden Age of man,—

“Great Spring before
Green'd all the year; and fruits and blossoms blush'd
In social sweetness on the self-same bough.”

Seasons: Spring, 1. 319.

The male flowers likewise, at the same time, are really handsome, with their large heads of fringe-like anthers.

Obs. II. I have long known this plant in fruit only; this, however, was owing to its autumnal flowering (different to the other species of this genus), for which I was not prepared.

Order LIII.—Scrophularineæ.

Genus 4. Gratiola, Linn.

1. G. concinna, sp. nov.

Plant procumbent, creeping, matted, sub-ascending. Stems 7–10 inches long, stout, purple-spotted, simple or slightly branched, puberulous with long white flattish-jointed glandular hairs. Leaves distant, sub ½ inch apart, orbicular and orbicular-elliptic, 2 lines long, membranaceous, of a pleasing green, glabrous, reticulately veined, with 4–5 small obtuse teeth each having a coloured spot at its base, petioled; petioles short, broad. Flowers rather few, axillary, solitary, peduncled; peduncles 1–2 lines long, stoutish, hairy. Calyx coloured, hairy, leafy, 5-parted to base; lobes long, unequal, 3-nerved, pellucid-dotted, toothed, recurved, tips obtuse; with two long similar bracts at base. Corolla 4 lines long, white, somewhat hairy; tube slightly curved, much veined; veins purple and branched above; limb spreading, 4-lobed; upper lip large, sub-bilobed, thickly clothed with yellow glandular hairs; lower lip 3-fid, each lobe emarginate. Stigma sub-rhomboid, dilated, flattish. Capsule sub-orbicular, turgid, green, glabrous, shining. Seeds brown, conical, very obtuse, a little curved.

Hab. Edges of a swamp in forest, south bank of the River Mangatawhainui, near Norsewood, County of Waipawa, where it thickly covers the ground in large spreading patches, presenting a very pleasing and neat appearance; March, 1886: W.C.

I have not noticed it anywhere else.

Obs. This species is evidently allied to G. nana, Benth., but it is a much larger plant, and is very distinct in several of its characters.

Genus 10. Euphrasia, Linn.

1. E. tricolor, sp. nov.

Plant perennial, sub-shrubby, 8–12 inches high; erect, com-

– 265 –

pact, branched above. Stems and peduncles densely puberulous. Leaves numerous in opposite pairs, mostly small, under 3 lines long (a few scattered lower ones 8–9 lines long), sub-rhombicovate, or obovate, impressed underneath as if stamped (sunk) within margin and between veins, once or twice toothed, the smallest entire. Flowers rather numerous, showy, solitary, axillary in opposite pairs; peduncle 1 line long. Calyx 2 ½ lines long, glabrous, sub-campanulate, 4-lobed; lobes large, obtuse, coarsely and prominently veined. Corolla ringent, inflated, pilose without, 9 lines long; white, with straight dark-pink veins (usually 8 above and 9 below), with a large orange spot at base of lower lip, and also of filaments; tube rather short; lower lobes large, spreading, sub-rectangular, with straight lateral margins; apices deeply emarginate and sinuous; upper lip recurved, lobes notched. Anthers glabrous, very obtuse, dark-umber; edges of valves largely ciliate with stiff white hairs; spurs of posterior pair equal, white, acute. Stigma sub-globose and (with style) finely pilose. Capsule oblong, 3 ½ lines long, obtuse, sub-compressed at top, with base of style persistent, puberulous. Seeds white, membranaceous; testa very lax, winged above, produced below, striate with minute transverse bars.

Hab. Bases of high wooded cliffs forming the banks of the River Mangatawhainui, near Norsewood, County of Waipawa; 1886: W.C.

Obs. I. This plant is nearly allied to E. cuneata, Forst., but differs from that species in several particulars: as in its larger lobes to both calyx and corolla, the latter spreading, richly coloured, with straight lateral margins; in its glabrous and coloured and largely ciliated (almost crested) anthers, with equal spurs, etc. But, as both Hooker and Bentham have each separately remarked (the former on our New Zealand, and the latter on the Australian species), “the several species are very variable”; and this I have also often proved.

II. A small variety of this plant (a. microphylla) is found 20 miles further south, in the open plains between Tahoraiti and Woodville; it closely resembles this one, only it is very much smaller in all its parts, its numerous leaves being only 1–1 ½ lines long; E. tricolor, var. microphylla, Col.

Class II.—Monocotyledons.
Order VII.—Liliaceæ.

Genus 5. Astelia, Banks and Solander.

1. A. hastata, sp. nov.

Leaves very long, sub-coriaceous, linear-acuminate, 4 feet long, 1 ½ inches broad at middle, tip filiform; many nerved, with 2 very prominent and coloured narrow ones; upper surface

– 266 –

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

glabrous, thickly pubescent underneath, as if minutely and regularly pitted (very apparent under a lens), sharply keeled; base much dilated and clasping, 4 ½ inches broad, black, shining, margins thin; veins spreading laterally, largely and coarsely reticulate. Male: Scape 2 feet long, stout, triquetrous, 1 ¾ inches circumference at base, composed of 7 nearly equal equidistant long single drooping racemes, the lowest 9 inches long, ¾ inch wide, each about 3 inches apart on scape; peduncles 1 inch long, each with an excessively long bract at its base, ovate, very acuminate, caudate, drawn out into a very long narrow tip, the lowest being 2 feet 6 inches long and 3 inches wide at the broadest; the upper portion light-green, sub-coriaceous and glabrous, the lower white, soft, and densely silky on both sides; the pubescence adpressed in stippled dots. Flowers yellow-brown, numerous, crowded, spreading, above 1 inch diameter; segments cut to base, narrow, linear, obtuse, ½ inch long, much longer than anthers, reflexed, with 1 central nerve running to tip and 2 lateral nerves ending half-way; all shaggy below on the outside (with pedicels and bracteoles), but the 3 inner have only a narrow central shaggy line to tip, with membranous glabrous margins, the 3 outer being hairy, with ciliated edges; pedicels 2 lines long, each with a small linear 1-nerved bracteole the length of pedicel. Stamens 3 lines long, spreading, rumpled; anthers, 1/10; inch long, triangular, obtuse, emarginate, largely hastate, their basal extremities curved and divergent, corrugated, somewhat bladdery. Stigma rather large, slightly produced, 3-fid. Female: Scape 15–18 inches long, very stout, composed of seven long narrow cylindrical simple flaccid racemes; much more compact on scape than male, each 9–10 inches long and ½ inch wide; peduncles very short, 2–4 lines, but the lowest 1 ½ inches; bracts much as in male, very silky below, the lowest 2 feet 6 inches long, and 2 inches wide at base. Flowers light-brown, exceedingly numerous and compact, very small, scarcely 2 lines long including ovary; segments not split to base, very small, about ½ line long, somewhat linear-ovate, reflexed from middle, the 3 outer more shaggy and ciliate, 1-nerved to tip; tips obtuse; the lower part of perianth forming a cup around the base of ovary; pedicels about 3 lines long, erect, close, but not crowded, sub-verticillate, patent, very shaggy, each with a narrow-linear bracteole at base the length of the pedicel; hairs flat, membranous, glossy, sub-ovate-lanceolate, nerved, white. Ovary (immature) ovate, beak produced; stigma, large, spreading, very pubescent; anthers (abortive) minute, triangular, acute, hastate, adhering closely to ovary, and with a part of the stamen appearing above the reflexed segment.

Hab. Forests, hilly country north of Napier, County of Wairoa; January, 1886: Mr. A. Hamilton.

– 267 –

Obs. This very fine species is naturally allied to A. solandri, A. Cunn., and to A. microspermum, Col.,* but differing largely from them both in several important characters, particularly in size, length, and shape of sub-panicles (racemes), in its extraordinarily long bracts, its different yellow-brown flowers, its very peculiar large corrugated and hastate anthers, and its curiously flattened broad and nerved hairs.

2. A. graminifolia, sp. nov.

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

Plant slender, few (7–8) leaved; apparently of simple distinct habit of growth. Leaves sub-membranaceous, largely drooping, 15–21 inches long, ¼ inch wide, linear-acuminate, tips filiform; the upper surface glabrous, dull greyish-green; the lower pubescent-hoary; hairs small, greyish, very closely adpressed; many nerved, with small distant transverse veinlets between them, and 2 very prominent narrow equidistant reddish nerves on the upper surface; margins slightly recurved and ciliate with fine shaggy white hairs; the base spreading, gradually dilated, 1 inch wide, very membranous, with fine silvery shining hairs thick on both surfaces. Scape (female) 6–7 inches long including panicle, erect, densely shaggy with white shining hairs, as also pedicels and outsides of floral bracts and bracteoles; panicle loose, 2 inches long, composed of 2 distant erect racemes and 3 intermediate solitary flowers; flowers in racemes close-set, pedicelled; pedicels 1/10th inch, patent; the upper raceme of top about ½ inch long, composed of 17 flowers; the lower raceme, distant about 1 ½ inches from the upper one, about ¾ inch long, composed of 20 flowers, with peduncle ½ inch, and a long leaf-like membranaceous and very acuminate bract, 6 ½ inches long at base; each of the solitary flowers having a long bract at base of pedicel. Flowers: perianth rather large, reddish-brown, glabrous, somewhat scarious, forming a very loose globular cup around ovary; segments free, ⅖th of perianth, narrow, linear-ovate, acuminate, 1-nerved, the nerve extending to base of perianth; a long very narrow linear sub-erect reddish 1-nerved bracteole at base of each pedicel. Ovary (immature) broadly ovoid-acuminate, rather suddenly contracted towards apex in forming a long beak; style O; stigma 3-lobed, puberulous; anthers (abortive) opposite segments, arising from segmental nerve at edge of cup, minute, long, filiform, sub-hastate.

Hab. Woods, hilly country north of Napier, County of Wairoa; 1886: Mr. A. Hamilton.

Obs. A very peculiar species, unlike all others of the genus known to me; yet possessing near affinity to A. spicata, Col.,

[Footnote] * “Trans. N.Z. Inst.,” vol. xvii., p. 251.

[Footnote] † “Trans. N.Z. Inst.,” vol. xiv., p. 335.

– 268 –

from which it differs in habit, length of leaves, panicle, pedicelled flowers, large loose perianth, and shape of ovary. Unfortunately I have had only one female specimen (all that was collected) to examine; this, however, was perfect and in good condition, except its immature fruit.

3. A subrigida, sp. nov.

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

Plant epiphytal, perennial, densely cæspitose. Leaves, about 20 to a single tuft or plant, rather short, equitant, diverging fan-like regularly and distichously from the base, which is sub-cylindrical, not triquetrous, linear-acuminate, 9–11 inches long, 4 lines wide, erect, sub-rigid, tips sharp, sub-coriaceous, glabrous, yellowish-green, striate, 10–12-nerved; nerves strong; the upper portion of the under-surface closely appressed with short greenish-grey glossy hairs, having a minutely pitted appearance; dark-brown, gradually dilated and largely clasping at base, with white shining hairs at the extreme base only. Female: Scape (including panicle) 12–14 inches long, rather slender, trigonous, woody, hard, thickly pilose above with appressed hairs, and shaggy at the base; hairs white, glossy; panicle very compact, short, sub-ovate, 5 inches long, composed of 7 sub-panicles; the lower three being compound, each containing 3 small racemes, the middle one longest, 2 ½ inches long, and the two laterals short, about 1 inch; the upper four being short simple racemes; each sub-panicle with a long membranous bract at base, the lowest one being 7 inches long, broad below, but soon very narrow, and much acuminate. Flowers very compact, brownish; pedicels stout, short, about 1/10 inch; perianth rather small, spreading, 6-fid to base, the three outer lobes larger than the three inner ones. Fruit small, globular, 1 ½ lines diameter, dull glaucous-green; style short, thick; stigmas 3, large, coalescing; seeds small, 12–18, sub-lunate-pyriform, thickest at apex, black, shining, minutely and thickly tuberculate (sub lente), gibbous on one side, slightly obtusely angled on the other, testa produced at funiculus end, sub-trifid.

Hab. High up in the upper forks of large forest trees, where the plant forms large dense masses; woods near Norse-wood, County of Waipawa; 1886: W.C.

Obs. This species of Astelia I have long known in its leafing state, but failed (until this year) in obtaining it in flower and fruit, and then only perfect female scapes; the male scapes being similar in size, etc., but old, or too long past flowering for accurate description. From the great quantity of barren plants that I have seen and examined at various seasons, I should suppose this species to flower but rarely. It seems to be widely different from all known and described species; approaching,

– 269 –

however, on the one hand A. spicata, Col.,* (which also very rarely flowers), and serving to unite that small species in a natural and progressive series with the larger species of the genus. I yet hope to succeed in obtaining the perfect male flowers during the approaching summer.

Order IX.—Junceæ.

Genus 1. Juncus, Linn.

1. J. luxurians, sp. nov.

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

Plant perennial; stout, tall, dark-green, forming thick bushy tufts and patches, that are sub-erect, drooping, and prostrate; rhizome creeping, with many small scale-like bracts, and sending up numerous new shoots every year; roots fibrous. Culms terete, leafless, 6–8 ½ feet long, 2 lines diameter below, smooth, minutely striate, upper portions soft and tender; tips very acuminate and sharp; the bases brown, glossy, with 3–4 adpressed sheathing bracts, the longest about 12 inches long; tips of bracts thin, very obtuse, sometimes acute; pith soft, woolly, and not continuous, yet not regularly broken or jointed. Panicle lateral, 8–12 inches from tips, large, effuse, pale-green, fascicled, sub 20 branchlets mostly compound; 1–3 being very large, stout, compressed, 2–3 inches long, each bearing at tip sub 10 compound branchlets; involucral bracts 1 ½ lines long, ovate-acuminate, very acute, membranous, white with a brown central nerve. Flowers 1/10 inch long, bibracteolate at base; bracteoles ovate, acute, membranous, white; pedicelled, pedicels long slender; perianth segments lanceolate-acuminate, very acute, rather longer than capsule, their centres bright green with broad white membranous margins. Stamens, 3; anthers small, yellow, oblong, with a minute connective; filaments short, rather broad. Stigmas 3, long and spreading, rumpled, plumose, dark-red. Capsule sub-prismatic, turgid, obtuse, very light brown, or dirty-white, shining, less than 1 line long. Seeds small, numerous, bright yellowish-brown, convex, oblong, sub-clavate; testa not produced.

Hab. In wet swampy hollows between hills, in a dense forest south of Norsewood, County of Waipawa; 1885–6, W.C.

Obs. This remarkably fine rush is found growing in middlesized tufts, and also in very large and dense patches, with the ground thickly strewed with them in a prostrate state, forming several layers, all living and dark-green. It is rather difficult to force one's way through a large sub-erect patch, owing to their height, their very close growth, and their being so greatly

entangled. Its extreme softness and tenderness (for a rush), its great length, and its prostrate habit, led me to suspect its being a species nova when I first saw it; but at that time (winter) I could not procure any good specimens. Through its being so soft and tender it is much browsed on and trampled by cattle, so that it is rather difficult to obtain whole and perfect specimens. Hitherto I have only noticed it growing in that one undisturbed forest swamp, where, however, it is plentiful.

Order XI.—Cyperaceæ.

Genus 13. Uncinia, Persoon.

1. U. polyneura, sp. nov.

Plant perennial, clear green, densely cæspitose, forming large bushy tufts, with numerous brown ovate bracts at base, deeply costate. Culms erect, 20 inches long, smooth, unequally triquetrous, the upper portion channelled on the two narrower sides; usually with 4 sheathing leaves nearly together at base, Leaves sub-erect and drooping, linear, long and narrow, 22 inches long, 2 lines wide, very acuminate; tips obtuse, thickened and very closely serrulate; their bases much sulcated; striæ broad, smooth, dark-brown; the upper surface glabrous, regularly striate, many and finely nerved (sub 24), with 3–5 stout whitish nerves equidistant between mid-rib and margin on each side; the lower surface finely scabrid; mid-rib narrow, smooth, slightly keeled in upper portion but very prominently so in the lower; margins closely serrulate; vagina entire, crescent-shaped, membranous; ligula small, sub-lunate, extending from midrib to margin. Spikelet 5–6 inches long, rather slender, lax; the upper 1 ½ inches male, dark-brown, cylindrical and narrow; the denticulation of rhachis very deep, with raised and thickened edges; bract O. Glumes closely imbricate, nearly 2 ½ lines long, narrow, ovate-acuminate, obtuse, margin of tip irregular (sub lente), dark-brown, obscurely striped, striate and prominently so at sides. Utricle 2 ½ lines long, a little longer than the glume, narrow, spindle-shaped, dark blackish-brown, glossy; bristle 2 lines long, slender, pale, much thickened and rugulose at the curve, tip of hook reflexed. Stigmas 3, long, lax, very shaggy, dark-brown.

Hab. Edges of forests and glades near Norsewood, County of Waipawa; 1886: W.C.

Obs. This plant in its general appearance has some affinity with U. alopecuroides, Col.,* but differs in the culms being twice as long, differently angled, smooth, and bractless; in the leaves not being scabrid on both surfaces, and the midrib smooth; in

[Footnote] * “Trans. N.Z. Inst.,” vol. xv., p. 335.

– 271 –

the spikelet being much more slender; in the glume being shorter than the utricle, and dissimilarly coloured and marked; in the utricle being longer than the glume and very dark brown; and in the bristle being shorter than the utricle.

Art. XXXIV.A Description of some newly-discovered Cryptogamic Plants, being a further Contribution towards the making known the Botany of New Zealand.*

[Read before the Hawke's Bay Philosophical Institute, 11th October, 1886.]

Introduction.

On this occasion, the last night of ordinary meeting of our Society for this year, I am again permitted to bring you our usual annual botanical offering, in a small basket of Crytogamic plants obtained from our inland woods and glens.

I have called it “our” offering; and this may require a few words in explanation. This plural pronoun is here used in a double sense: (1) To let you know that I have again been largely assisted by kind and liberal, hearty and active, coworkers in this part of the botanical field, who all work con amore in this matter: among them I would particularly mention with thanks three of our active members—Messrs. H. Hill, A. Hamilton, and D. P. Balfour—to whom not only myself and our local branch auxiliary Society, but the New Zealand Institute as a scientific body, are largely indebted. And (2) that this offering or tribute is one made by, as well as from, our New Zealand woods. For, privileged as I am to present and make known this, their free gift, and thus for a short time briefly occupying the position of their herald or ambassador unto you—coming hither directly from them, and from long and oft-repeated sojournings in their homes and company, and understanding their thoughts and quiet reasonings, and silent yet the more expressive language—I would beg permission to say a few words respecting them.

Among the many and varied congenial homes of the great Crytogamic family, in those deeply secluded glens and mountain woods, far away from the busy life of towns, and even the solitary haunts of the isolated “bush” woodman, is the place par excellence for the disciple of Nature to study, to admire, to learn, to know; and so learning, so knowing, to hold converse with her and her beauties; and, through their teachings, with

[Footnote] * In continuation of paper on same subject, read in the previous year. See “Trans. N.Z. Inst.,” vol. xviii., pp. 219–255.

– 272 –

the one Great Mind and Author of all I One of our esteemed British classical poets, Thomson, in writing on this subject, has truly said,—

“Here wandering oft,
I solitary court
Th' inspiring scene: and meditate the book
Of Nature ever open.”

For (as I have said to you on a former occasion) I believe in the universal language of Nature: and it is with feelings such as those that I have not unfrequently detected new and hitherto hidden and unknown novelties; and when thankfully gathering them have sometimes said, solus, or spoken out to them: “Come out of your obscurity, and be seen in society. Come and be introduced to science. Come and add your tribute also, however small, to the further display of the many great and wonderful perfections of Nature; and, in so doing, more openly fulfil the imperative injunction made to you two thousand years ago, in the words of that very ancient song: ‘Benedicite universa germinantia in terra Domino; laudate et superexaltate eum in sæcula.”‘And then, at such times, I have further thought: How many thousands of years—may be, myriads of ages—since this wee little wondrous delicate and frail yet perfect form first appeared, whether created or evolved; and how, in spite of all opposing and powerful elemental influences, and cataclysms, and volcanic eruptions, has this little microscopical plant held its own, fructifying, and shedding its tiny seeds in their proper season, and so overcoming and riding triumphant over all opposition and every adverse power? Moreover, when I have also occasionally found a little Cryptogam which I knew to be also a denizen of another part of the globe—it may be of the Antarctic islets furthest South, or of Tasmania, or Australia, or the Islands of Polynesia; or of the far-off specks in the vast Southern Ocean, the Crozets, or Kerguelen's Land; of the Cape of Good Hope, or Cape Horn; of the Peruvian Andes, or of the European Alps; of the riparian banks of the Amazon, the Thames, the Tweed, or the Shannon; of the summits of our own Ruahine Mountains, or of the Scottish Highlands—what a further theme for thought! Where the commencement, the outset, the Alpha, the origin? or were there originally more than one such? And, if so, did such embryos, situated at the antipodes of each other, commence life together?

Possibly, or rather very likely, some of the younger portion of my audience here this evening may think these remarks of mine strange, aberrant, or at all events peculiar; pertaining, it may also be thought, to the garrulity of old age, and following as a fitting sequence to my expressed belief in the universal language of Nature. To all such, (if there be any), I would merely reply that thoughts like those I have touched on are (1)

– 273 –

not unreasonable; (2) are eminently pleasing, illuminating, and informing; (3) are qualified to raise our human nature; and (4) to lead us on to more correct views of the Great Father and Author of all. Once more will I quote a few highly expressive lines from my favourite poet Thomson:—

“Nature, attend! join every living soul,
Beneath the spacious temple of the sky,
In adoration join; and ardent raise
One general song—to Him!
Soft-roll your incense, herbs, and fruits, and flowers,
In mingled clouds to Him, whose sun exalts,
Whose breath perfumes you, and whose pencil paints.”

But to leave the mountain-tops, first gilded by the sun, and the purer air of the balmy pine forests and heights, not to mention their kindred poetical musings, and to descend to the plains—to the technical and prosaic facts and descriptions of our few little Crypts.—I have to observe that four of the orders of the great Linnæan class Cryptogamia are here represented—viz., Filices, Lycopods, Musci, and Hepaticæ. Of the first order, or ferns, I have only one novelty, a species of Lomaria; of the second, or Lycopodium, I have also but one new species; of the third, or mosses, I have five new species, belonging to three genera—viz., Polytrichum, Hypopterygium, and Hookeria, all fine mosses and well represented here in New Zealand; and of the fourth, or liverworts, I have 40 species, pertaining to no less than 11 genera, some of which, as Jungermannia, Plagiochila, Mastigobryum, and Frullania, were already remarkably large and cosmopolite. In the “Synopsis Hepaticarum,” published 40 years ago, Plagiochila possess 189 species, Jungermannia 195 species, Mastigobryum 64 species, and Frullania 155 species; and these large numbers of species have been subsequently increased with many more; indeed, out of this present small collection there are no less than 5 species of Plagiochila, 16 species of Mastigobryum, and 6 species of Frullania; while others of those smaller and rarer genera now added to by me are still very limited, both as to the number of their known species and their area.

The total number of Cryptogamic novelties described in this paper is 47; and while all will prove interesting to the working botanist and devoted disciple of Nature, some of them, it is believed, will prove no less so to the cultivated and cursory, though less technically skilled, observer.

Lastly, and in conclusion, (as I do not wish to repeat my former observations over again, though equally applicable here), I would respectfully beg my hearers, being members of the Institute, to read and note what I have said in my introduction in my paper of last year on this subject, in connection with this present paper.

– 274 –

Class III.—Cryptogamia.
Order I.—Filices.

Genus 16.* Lomaria, Willdenow.

1. L. intermedia, sp. nov.

Plant small; caudex ½–¾ inch, indistinct, formed of the bases of old stipites and wiry roots; tufted, few fronded; fronds sub-erect and spreading, pinnate; stipes rather slender, blackish-brown, glabrous, succulent, somewhat brittle, deeply channelled above, as also is the rhachis. Sterile fronds, 7–8 inches long, (including short stipe, ¾ inch), 1 inch wide, linear-lanceolate, rachis, flexuous, green; pinnæ 16–18 pairs, alternate, distant, membranous, light-green, glossy, thickly dotted beneath with minute red scales, oblong, sides straight, very obtuse, margins crenate, adnate, the lower base much excised and sub-truncate, the upper base slightly sub-auriculate or produced, but not extended on rhachis, 3–4 lobes at top confluent, the uppermost lobe broadly ovate, obtuse; the lowermost 5–6 pairs of pinnæ small, sub-orbicular, and sometimes opposite; veins 4–5-jugate, obscure, the lower forked, upper simple, extending nearly to margin, tips clavate, the lowest basal vein always 3-branched, and proceeding from the rhachis, not the midrib: fertile fronds much longer and more slender, 9–11 inches (including stipe, 2 inches), pinnæ 16–18 pairs, alternate, very distant, sub ½ inch, narrow linear almost filiform, 6–7 lines long, ½ line wide, obtuse, margins sub-crenulate, presenting a regular knobbed or beaded appearance, arising from the clavate tips of the veins, adnate, slightly decurrent, ultimate lobe long and very narrow, the lowermost segments exceedingly small; rich red-brown; margin of indusium finely lacerate, as obtains in L. filiformis, A. Cunn.

Hab. Scattered in damp shaded localities, Seventy-Mile Bush, County of Waipawa; 1880–86: W.C. In forests near Palmerston, County of Manawatu; 1886: Mr. A. Hamilton.

Obs. I. This species is allied to several of our smaller Lomariæ,—as, L. lanceolata, Spr., L. pumila, Raoul, L. membranacea, and L. oligoneuron, Col.,—but more closely to L. membranacea, from which species it differs in its larger size, its crenate (not “dentato-serrate”) sterile pinnæ, which are also of a different shape, more obtuse and distant, excised at their lower and produced at their upper bases, much fewer veined, and minutely dotted with red scales beneath; while the fertile

[Footnote] * The numbers attached to the orders and genera in this paper are those of them in the “Handbook Flora of N.Z.”

[Footnote] † Vide “Trans. N.Z. Inst.,” vol. xvi., p. 346.

– 275 –

pinnæ are also very much narrower, and adnate, with sub-crenulate margins. Those four species form a compact little natural group.

II. After long search, I found 4 small scales at the bases of 2 stipites. These are very short, about 1 line long, black, subulate, with a broad membranous and entire base, and large black oblong cells.

Order II.—Lycopodiaceæ.

Genus 2. Lycopodium, Linn.

1. L. novæ-zealandicum, sp. nov.

Plant small, dependent, lax, soft; main stem slender, 3–4 inches long, single, leafy to base, once forked at top; forks ½–1 inch long, cylindrical. Leaves sub-trifarious, glabrous, shining pale-green, spotted with brown dots, lowermost rather distant, loose, spreading, recurved, sub-linear-spathulate, 4–6 lines long, ½ line wide, transversely wrinkled, narrowed at base and slightly decurrent; tips sub-acuminate, obtuse, thickened, nerve broad and strong; margins entire, pale, sub-cartilaginous; upper leaves much smaller, closer, imbricate, sub-appressed, nerve obsolete. Capsules axillary in upper leaves of main stem and on forks, large for plant, orbicular with a deep sinus, broader than base of leaf, yellow; valves gaping, thickened at margins; spores sub-orbicular, minutely roughish. Scale—or capsule-leaves on forks, sub 2 lines long, subulate, erect, very obtuse at tips, much dilated at base, clasping.

Hab. Epiphytical on fern-trees, open marshy glades in low forest, bank of River Mangatawhainui, near Norsewood, County of Waipawa; 1886: W.C.

Obs. I. Of this little plant I obtained five specimens from three fern-trees, two of them in full fructification and nearly alike in size and shape; two of the barren specimens were a little larger (4–5 inches, main stem), but much the same in form; their colour greener.

II. This is a small species of the Selago section; apparently pretty closely allied to L. taxifolium, Sw., (ap. fig. Hook. et Grev. Gen. Filicum, tab. Ixxxviii.), a Jamaica and St. Helena species; but that plant is much larger, and its leaves are sub-sexfarious, rigid, and acute, and its capsules reniform. This plant is also nearly allied to L. gnidioides, Linn., a Cape and Mauritius species. It differs much from its nearest New Zealand congener, L. varium, Br., in its much smaller size, in its narrower leaves of a different shape, being more lax and remote, and not so thickly set around the stem, in the total absence of quadrangular spikes, its differently-shaped capsules, and its softness. Sir J. D. Hooker has given no less than five drawings of different forms of that variable species in his “Flora

– 276 –

Tasmaniæ,” (tab. clxx.), but all without fructification. Another drawing of that species, with fruit and dissections, is also given by Sir W. J. Hooker, (Ic. Filicum, tab. 112), which is more in accordance with the New Zealand states of L. varium; but all differ widely from this plant.

Order IV.—Musci.

Genus 46. Polytrichum, Linn.

A. Calyptra nearly glabrous.

IV. Polytrichadelphus, C. Müell. (Cyphoma, Hook. fil. and Wilson.)

1. P. polycarpum, sp. nov.

Stems erect, 2 inches high, rather stout, once forked, bare at base. Leaves 3 ½ lines long, thickly set from near base, sub-patent, spreading and decurved below on stem, subulate, acute, glabrous, flat on upper surface not canaliculate, sub-rigid, opaque, narrowly margined, serrate, nerved throughout, darkgreen with brown tips, lurid in age; bases broad, sub-quadrate, 1 line wide, amplexicaul; cells very minute, sub-orbicular distinct and transverse in the margin of leaf near contraction, narrow linear-oblong in the basal portion; perichætial shorter than stem-leaves. Fruit-stalks lateral, slender, erect, 1 ½ inches long, slightly flexuous, twisted at top, light-red, shining, 4–5 to a branch. Capsule broadly oblong, a little contracted at mouth, sub-horizontal and inclined, 2 lines long, somewhat strumous, flat and slightly concave above, conspicuously 2-angled at the sides (sometimes obscurely 4-angled), semi-terete below; light-brown (becoming darker in age), shining, mouth orbicular; teeth 64, rather short, hyaline, acute, sinuses broadly rounded; the circular epiphragm radiate, margin uneven. Spores circular, transparent at centre. Calyptra longer than capsule, narrow linear, 2 ½ lines long, straight, red, glabrous, tip obtuse, hirsute at extreme apex; hairs very short and thick; membranous and lacerate at base.

Hab. Hilly woods, east bases of Ruahine Mountain Range, County of Hawke's Bay; 1885: Mr. A. Hamilton.

Obs. This species will range under Polytrichadelphus, C. Müell., and is allied to P. magellanicum, Hedw. It differs however, from that species in its more simple stems, in its leaves being margined and more serrate, with much larger sub-quadrate bases, (resembling those of P. giganteum, Hook., as given by Schwaeg., tab. cccxxv.), and in their not being canaliculate and lamellate; also, in its slender seta, the sub-strumous form of its capsule with circular mouth, its shorter and more acute teeth with broader sinuses, and its longer calyptra.

– 277 –

Genus 67. Hypopterygium, Bridel.

1. H. hillii, sp. nov.

Plant closely cæspitos in small tufts. Stems about ½ inch high, thickly tomentose throughout with dark brown tomentum. Frond sub-deltoid-orbicular, pale yellowish-green, 5–6 lines broad, the lower branches 2-pinnate, the upper simple. Leaves: on the stem, deltoid-acuminate, nerveless, margins entire slightly uneven, cells long and narrow; on the primary branches, distichous, spreading, close and slightly imbricate, broadly ovate, much apiculate, dimidiate, very thin almost pellucid, stoutly margined; margins serrate; nerve extending about three-fourths of leaf; cells small and sub-orbicular at tips, larger and oblong at centre and base with minute interstitial cellules; dorsal leaves orbicular, very largely apiculate, the mucro stout and acute and nearly half the length of the leaf, margined, slightly denticulate near apex; nerve stout, extending beyond middle; cells as in those of the primary branches; perichætial narrow-ovate, much acuminate, acute; cells very long and narrow. Fruit-stalk, 5–7 to each plant, about ½ inch long, reddish, erect, tip slightly curved. Capsule a little drooping, oblong, red, minutely and regularly papillose, broadest and tubercled near base; cells large, sub-orbicular-quadrate; outer teeth dark-brown, subulate, acuminate, with no median line but a dark line at margins, transversely sulcate; the inner teeth nearly as long as the outer, pale, subulate, acuminate, bifid, tips almost capillary, dark jointed. Calyptra as long as the capsule, dimidiate, narrow, subulate, acute, a little curved, whitish below, tip brown.

Hab. Forests, Daneverke, County of Waipawa; 1885; Mr. H. Hill: forests near Norsewood, same county; 1886: W.C.

Obs. This elegant little fern-like moss is allied to the smaller species of Hypopterygium, (“Sec. I. a. Leaves not mixed with bristles; ** branches 2-pinnate;”) of which we have some half-dozen or more known and described species, but it is very different from them all. I have, with much pleasure, named it after its discoverer, Mr. Henry Hill, B.A., Inspector of Government Schools for the Hawke's Bay District, whose ready zeal and care in collecting, and kindness and liberality in imparting botanical specimens of rare plants, I have long thankfully experienced, as my published botanical papers will abundantly testify.

2. H. pachyneuron, sp. nov.

Plant, rhizome stoutish, creeping, 2–3 inches long, brown, slightly hairy. Stems single, distant on rhizome, erect, 1 inch high, rather slender, glabrous, leafy and green above, bare and brown below. Frond sub-orbicular-cordate in outline, ½ inch

– 278 –

long, green, inclining to pale-green at tips of branches; branches bi-pinnate throughout, very close set and overlapping. Leaves: lateral, distichous, spreading, imbricate, ovate, acute, slightly and distantly serrate at tips, margined; nerve very stout and broad at base and extending beyond middle; cells rhomboidal, larger at base; the dorsal leaves broadly orbicular, apiculate, margined; margins entire, slightly uneven; nerve vanishing beyond middle; cells oblong, small at tip and margins, larger at centre and base; stem leaves similar to dorsal; perichætial narrow oblong-lanceolate, very acuminate, entire; cells narrow oblong rectangular. Fruit-stalk: 8–9 on one plant, each singly arising from the base of a branch on the main stem, or from a fork of the primary branches, slender, erect, red, 5 lines high, shorter than frond; base very filiform, vaginant; vagina large, cylindrical, dark-brown. Capsule sub-erect and horizontal, about 1 line long, oblong, reddish, smooth, slightly rugose at base; outer teeth dark-brown, subulate, with a dark median line, very closely transverse-sulcate, edges much roughened (sub-denticulate) with numerous dark teeth, greatly acuminate, tips flexuous, curved; inner teeth just as long as outer, pale, remotely barred with a median line, acuminate, bifid for one-third of length from tip, with three filiform jointed ciliæ, shorter than teeth, alternate between them.

Hab. Near Wairoa, Hawke's Bay; 1885: Mr. A. Hamilton.

Obs. This is another species of the same subsection as the preceding, and is also pretty closely allied to its known New Zealand congeners.
