Art. XXIII.—Notes on New Zealand Mollusca.

[Read before the Auckland Institute, IIth July, 1881.]

During my recent trip to England I took with me the late Dr. Sinclair's collection of New Zealand shells, mostly collected in the North Island, and had them named according to the specimens in the British Museum by the aid of Mr. G. B. Sowerby, junr., and Mr. E.A. Smith, of the British Museum, to both of whom my best thanks are due for their kindness. On my return to the colony I have compared these with Professor Hutton's type specimens, in the Colonial Museum, Wellington, and in the Dunedin Museum. The following is the result of my researches, which may probably prove useful to those interested in New Zealand conchology. The pages given refer to the new edition of the “Catalogue of New Zealand Mollusca,” by Professor Hutton; Wellington, 1880.

Pages

16.

Helix reinga—Doubtful if ever found in New Zealand.

41.

Conus aplustre—Add to catalogue. I have a single specimen from the Bay of Islands, but it is doubtful whether either this or Conus zealandicus really belong to New Zealand. They may have been dropped from some South Sea whaler, of which many visit the Bay of Islands.

42.

Acus kirki is Terebra tristis of Deshayes and T. antarctica of Smith.

43.

Pleurotoma zealandica—Amend description as follows: instead of “tapering gradually” read “gradated” read “cauda set round with small brown keel.”

44.

Drillia cheesemani—Omit, as this is the same as Pleurotoma zealandica, Smith.

45.

Defranchia luteo-fasciata—Substitute Drillia sinclairi, Smith, manuscript. D. luteo-fasciata is a very small West Indian shell described by Reeve.

48.

Trophon stangeri is clearly the same as Fusus cretaceus of Reeve.

54.

Cominella lurida and huttoni are the same, and are the quoyana of the British Museum.

54.

Cominella funerea is C. costata.

55.

Nassa rutilans, etc., are not New Zealand. I have N. cancellata, A. Adams, N. semigranosa, and Strombus variabilis, all found at Bay of Islands, but all doubtful, as before remarked as to Conus.

59.

Fasciolaria trapezium—Add to catalogue. I have one specimen collected by the late Dr. Sinclair.

60.

Mitra rubiginosa, Hutton—Should be changed as there is a M. rubiginosa of Reeve, Proc. Z. Soc., 1844.

62.

Marginella albescens can hardly be distinguished from M. australis, although a little smaller.

63.

Marginella muscaria, Lam.—Substitute for Erato lactea, Hutton.

66.

Cypræa—I have a specimen of Cypræa found on the beach at the Bay of Plenty in by Rev. Mr. Chapman, but I fear that both this and C. punctata are dropped shells, not New Zealand.

68.

Struthiolaria inermis is the same as australis.

70.

Scalaria lyra is not the lyra of Sowerby. It is most like rubrolineata, but the band is on the middle of the whorl of the latter.

70.

Scalaria jukesii—Add to catalogue. I have specimens; also of another new species.

Scalaria wellingtonensis—Add to catalogue. Described in “Trans. N.Z. Inst.” vol. xii., p. 307.

73.

Eulima chathamensis is Rissoa variegata, Angas.

92.

Calcar cookii is Cookia cookii of the British Museum.

Calcar imperialis is Imperator heliotropium of the British Museum.

Pages

95.

Diloma æthiops is not Monodonta reticularis of Gray; the latter ought to be replaced in catalogue, as I have both.

96.

Diloma gaimardi is same as D. sulcatus, Wood.

96.

Trochocochlea mimetica, Hutton, is M. reticularis, Gray.

98.

Zizyphinus granatus, Chemnitz, is not the same as Z. tigris, Martyn; the granatus of Dunedin Museum is tigris.

103.

Margarita fulminata should be a Gibbula.

Margarita, nov. sp.—Add to catalogue. Perhaps Gibbula inconspicua of Hutton, p. 102.

106.

Emarginula candida, A. Adams—Add.

Emarginula tenui-costata—Add.

Tugalia ossea—Add.

107.

Tectura pileopsis—Add.

Tectura fragilis—Add.

110.

Patella stellaris—Add. Like one named corticata in Dunedin Museum, but not quite.

113.

Lepidopleurus crocinus, Reeve—Add. This is probably L. empleurus, Hutton.

118.

Ischnochiton antiquus, Reeve—Add.

121.

Haminea zealandiæ and obesa are the same.

136.

Anatina tasmanica is A. angasii.

143.

Tellina disculus is not the same as sublenticularis of Sowerby.

159.

Cardita zealandica is the same as compressa of Reeve.

167.

Mytilus edulis is neither edulis nor dunkeri of Reeve.

171.

Pecten vellicatus, Hutton, is the same as convexus, Q and G, and roseapunctatus, Reeve.

Adamsia typica—Add.
