Genus Anomalina d'Orb., 1826.

The first two species described below belong to the coarsely perforate group of “grosserugosa Gumbel,” rubiginosa Cush., dorri Cole, etc., but the others have a superficially different appearance. The aperture and shell development, however, seem essentially the same, and no constant point has been observed to allow of even subgeneric separation. Some of the species resemble such gyroidine types as Rotaliatina, but are distinctly perforate, while Gyroidina and its allies, have such minute pores that the surface appears quite smooth; the anomaline aperture is also more widely open, with usually a better develped lip and nearly always extends well over on to the dorsal side and back along the spiral suture. If the dorri group were split off on the basis of pore size, Cibicides would also need division on this count, and the utility of this is doubtful.

Anomalina visenda n.sp. (Plate 65, figs. 116–119.)

Shell large, inflated, dorsally 2 coils visible, ventrally involute with deep umbilicus; 8 chambers in last coil, swollen with distinct but not deep sutures, periphery flatly rounded; heavily ornamented above and below by intersecting diagonal ridges, producing pitted surface, like very coarse Globigerina. Centrally this ornament coalesces into regular, raised smooth patches dorsally and heavy rugae ventrally; anteriorly ornament weakens, last chamber with smaller pits and punctae. Periphery slightly smoother, terminal face quite smooth, aperture normal. Size 1.1 mm.

Type from 5371, type Wanstead, Upper Bortonian. Also in Lower Bortonian (5570); not seen below or above this. Related to the Mexican Lower Eocene aragonensis Nuttall, which has much coarser and more distinct pitting, especially ventrally.

Another species of this line is Anomalina aotea n.sp. (plate 65, figs. 111–115), which is smaller with rather fine pitting dorsally and smooth shining ventral surface, without medial coalescence or rugae. Last chamber practically smooth all over, 6–7 in last coil. Size, 0.5 mm. Type from 5179B, Hampden, Upper Bortonian. This has a much longer range, extending also into Piripauan and throughout lower Tertiary. Large specimens, perhaps a little more lobulate, occur commonly in the Weber (5835), Oxford Chalk (5047), and other Whaingaroan strata, but are not easily separable even from Piripauan forms (5301, 3270). This may be the upper limit of aotea.

Anomalina vitrinoda n.sp. (Plate 65, figs. 120–122.)

Compressed, periphery acutely rounded, flattish above and below. Ventrally involute, smooth and shining, sutures strongly curved at

outer two-thirds, then flush; dorsally with 1 ½ visible coils, 13 chambers in last, sutures lightly curved, heavily limbate, spaces between and central knob coarsely punctate. Umbilicus filled by glossy knob above and below. Aperture like Cibicides, narrowly rounded on periphery, sharply limited ventrally, continued back along dorsal suture with thin lip, remnants from previous chambers projecting as little ears over suture. Size, 0.6 mm.

Type from 5089, Eason's Hill “Blue Bottom,” Westland; true Hutchinsonian. Common from here to Tongaporutuan (often seen in Taranaki beds). Ranges down to Whaingaroan (1279, 3281, Waitetuna Estuary); examples from here may be Stache's Rosalina orbiculus (Novara Pal., vol. 1, p. 285; Pl. 24, f. 34; 1864), but it will be better to use a definite name until his types can be reexamined, since his figure resembles several species.

A distinct relative in Bortonian, Anomalina semiteres n.sp. (plate 65, figs. 123–127), is less compressed, planoconvex, the almost flat base similarly smooth and shining, dorsal punctation finer and denser, radial sutures increasingly limbate near inner margin of coil and projecting as blunt points into groove between coils (which are more visible ventrally), dorsal knob somewhat broken into pustules, about 11 chambers per coil; size, 0.5 mm. Type from 5179B, Hampden, Upper Bortonian; not in Lower Bortonian; ranging into Kaiatan (5601, etc.), but no higher.

Anomalina miosuturalis n.sp. (Plate 65, figs. 128–131.)

Very compressed, periphery bluntly narrowly angled, bevelled each side, a little flatter on top than below. Ventrally involute, with moderate umbilicus; dorsally with 1 ½ visible narrow coils, 15–16 chambers in last, sutures strongly curved, slightly and evenly limbate. Surface finely and densely punctate. Aperture with lip running from umbilicus, especially prominent round periphery and back along spiral suture for up to half a coil. Size, 0.5 mm.

Type from 5707, upper part of Middle “Blue Bottom,” Eight-mile Creek, Hohonu S.D., Westland. Common in Miocene; entering in Duntroonian (5660) and ending in Awamoan.

A close relative common in the Eocene is Anomalina eosuturalis n.sp. (plate 65, figs. 132–137), differing only in indistinct radial sutures (broadening and poorly marked), fewer chambers (about 13), less curved sutures and obscure central portion, much more encroached on by last coil and lip. Size, 0.6 mm. Type from 5068A, Burnside marl; Tahuian. Ranges from Lower Bortonian (5540) to Whaingaroan (1279, 5047).

Anomalina subnonionoides n.sp. (Plate 66, figs. 172–180.)

Inflated, almost symmetrical, periphery very broadly rounded. Dorsally and ventrally involute with fairly wide, deep umbilicus filled by thickening of spiral suture as in some Nonion species; 1 visible coil, 10–11 chambers, densely punctate, aperture wide with prominent lip continued into ventral umbilicus and prominently running back for some 3–4 chambers along dorsal spiral suture; end face almost bisected by earlier periphery, but a little deeper and more convex ventrally. Size, 0.6 mm.

– 460 –

Type from 5273, Awamoan; common in Miocene. Connects up this group with the symmetrical Nonion at one extreme, while the compressed very asymmetrical species almost connect with Cibicides at the other. It would be a very slight step to develop this form from such a Nonion as soldani d'Orb. or halkyardi Cush. Related to the Recent Australian nonionoides Parr (P.R.S. Vict., vol. 42, pt. 1, N.S., p, 231, pl. 22, fig. 38, 1929), but thicker, less coarsely perforate, and without the lobulate periphery. Ranges from Duntroonian (Chatton) to Awamoan.

Anomalina spherical n.sp. (Plate 66, figs. 166–171.)

Very globose, simulating Rotaliatina, periphery broadly rounded, gently curved above, very convex below. Ventrally involute, very deep, narrow umbilicus with flatly rounded margin; dorsally with about 3 visible coils, 7–8 chambers in last, sutures fairly straight, not limbate; surface finely and densely punctate. Aperture narrow, long, with prominent lip merging into umbilical margin below, usually not reaching spiral suture above, but sometimes running back along it a little. Size, 0.5 mm.

Type from N. of Hen and Chickens in 30 f. Not uncommon during Pliocene (e.g., 4317 basal Opoitian), rare in Taranakian. (5703, 5645), not seen earlier. Has only superficial resemblance to Rotaliatina, the texture, type of aperture and terminal face all disagreeing with sulcigera and like the other Anomalinas here described.

Anomalina pinguiglabra n.sp. (Plate 66, figs. 160–165.)

Fairly inflated, periphery very convex, flattish on top, convex below. Ventrally involute with narrow, deep umbilicus; dorsally with large proloculum and nearly 2 visible coils, 9 chambers in last, sutures lightly curved, not limbate; surface finely punctate. Aperture wide, margined by prominent lip continued into umbilicus and back along spiral suture for 1 chamber. Size, 0.6 mm.

Type from 5273, Awamoan. Stands halfway between macraglabra and spherica. Ranges from Duntroonian (Wharekuri) to Awamoan.

Anomalina macraglabra n.sp. (Plate 66, figs. 141–143.)

Moderately compressed, periphery bluntly angled, flatly convex on top, flatly convex below. Ventrally involute, with narrow not deep umbilicus; dorsally with 3 visible coils, 10–11 chambers in last, sutures strongly curved, not limbate, surface finely punctate. Aperture narrow, with marginal lip running into umbilicus and round periphery, but not back along spiral suture. Size, 0.57 mm.

Type from 5273, Awamoan; common in Hutchinsonian-Awamoan. Has been referred to as glabrata Cush., but topotypes of that Recent Samoan species, though with same chambering, are dorsally depressed, with wide umbilicus mostly plugged, coarser punctae, and a lobulate periphery. Begins in Duntroonian (5660) and lasts in abundance to Awamoan.

Of same style is Anomalina eoglabra n.sp. (plate 65, figs. 138–140) from the early Tertiary; general proportions and coiling same but smaller, with 13–15 chambers in last coil, dorsal sutures

less curved, umbilicus a little narrower and shallower; size, 0.45 mm. Type from 5601, Kaiata mudstone; also in Piripauan (3250A), Bortonian (5540), and Whaingaroan (5047).
