Genotype: E. chattonensis n.sp.
Intermediate between Buliminella and Buliminoides, more elongate, but with much lower chambers than Buliminella, the loosely wound spiral but little embracing, apertural face not pyriform but suboval and subterminal, small in area, central aperture chink with few radiations—this is like Buliminoides, but no heavy ornament or true uniserial character.
Buliminella westraliensis Parr, 1938 (Journ. Roy. Soc. W.A., vol. 24, p. 80, pl. 2, figs. 3, 4) from the West Australian Upper Eocene belongs here, having the characteristic twisting, irregular chambers and aperture; other Australian species occur in the Janjukian of Table Cape.
Elongobula creta n.sp. (Plate 27, figs. 88–91.)
Subcylindrical, about 4 loosely and irregularly wound coils, with 3–5 chambers of varying size, appearance very uneven and distorted; any part may suddenly become more swollen; apex very blunt; sutures faint, last chamber reduced, narrowing to small apertural face set almost in plane of length, with tiny central opening in a hollow. Size, 0.55 mm.
Type from 5665, abundant; index of Upper Piripauan, also present in Poverty Bay mid-Rakauroa (3250A), and Motunau Chalk Marl (5716) above sulphur sands.
Elongobula chattonensis n.sp. (Plate 27, figs. 92–96.)
Like creta in irregular loose twist, with bulges in odd places, but much more elongate, strongly compressed in upper half, which narrows suddenly to sharply spined apex; sutures even, less marked and surface smoother, size and junctions of chambers extremely irregular, last chamber hardly contracted, apertural face a sudden oblique truncation with a larger more central opening than creta. Size, 0.52 mm.
Type from 5368, Chatton S.D. (55 chs. S.E. of Trig. F); Duntroonian. A close relative is Elongobula lawsi n.sp. from 5636 (Te Kauri Stream, near Hauturu, shell-marls of basal Te Kuiti above coal outcrop); this differs only in larger size and pronounced taper (being acicular instead of subcylindrical), absence of compression, and but little twisting. They seem to be northern and southern representatives in beds of the same age.
Ehrenbergina marwicki n.sp. (Plate 28, figs. 112–118.)
Very close to mestayeri Cushman, 1922 (see Cushman, 1927, Proc. U.S. Nat. Mus., vol. 70, art. 16, p. 4, pl. 1, fig. 9), but differing in less ridged ventral surface; in Recent species a sharp angle runs from each spine along chamber, in Miocene form chambers are almost flat and terminal face distinctly convex; aperture larger, spines weaker. Size, 1 mm.
Type from 5273; Lower Hutchinsonian to Awamoan. Mestayeri occurs down to Opoitian (2058, etc.); another poorly preserved distinct form is in Jedburgh Taranakian.
Ehrenbergina osbornei n.sp. (Plate 28, figs. 120, 123, 124.)
Wider than marwicki, with terminal face but little convex; ventral side with subobsolete medial ridge, smoothed away each side instead of excavate; chambers obscure and flatly convex; dorsally overlapping at third instead of quarter of width; spines few, distant, but strong spikes instead of minute points. Size, 0.6 mm.
Type from G.S. 1342; not present below Tutamoe. Also in Mokau (5197), Cheviot Grey Marl (5557), and Lower Poha (3079) (Tongaporutuan.

Ehrenbergina fyfei n.sp. (Plate 28, figs. 119, 121, 122.)
Dorsal surface very convex, ventral flat, no medial ridge; last 2 chambers more than half ventral surface, inflated, anterior outline very convex, spines few, tiny, downward pointing. Size, 0.7 mm.
Type from 5569, Conway River, Hundalee, grey marl; Tongaporutuan. Also in 3114, Poverty Bay (Waimata, Upper Poha).
Patellina piripaua n.sp. (Plate 28, figs. 125–127.)
A high, rounded central cone spreading out laterally to thin disc in adults, base flat or little concave, with wide marginal ring finely divided into chamberlets and a central space with 2–4 aperture impressions dorsally smooth, opaque, disc showing several chambered rings. Size, 1.1 mm.
Type from 5329, East Grey Stream; also 5664, Mid-Waipara. Index of Piripauan. Like Parr and Collins, I cannot separate British specimens of the Recent corrugata Wm. from New Zealand examples—Pliocene of Castlecliff (5215) and also the Oligocene Ototaran (5182, etc.), where it is common.
Notorotalia serrata n.sp. (Plate 29, figs. 152, 153.)
Close to spinosa Chapman, 1926 (see Finlay, 1939, Trans. Roy. Soc. N.Z., vol. 68, p. 517), more compressed, with subequal dorsal and ventral convexity, more numerous strong spines with spreading bases, giving a serrate appearance; spinosa has only a few very irregular tiny needle-shaped spikes not lobating periphery. Size, 1.4 mm.
Type from 5650, East Grey Stream, marls 90 ft. above Weka Pass Stone; also in Pachymagas beds, All Day Bay. Index of Lower Hutchinsonian.
N. spinosa is common in true Hutchinsonian and Awamoan; another Hutchinsonian form may be separated as Notorotalia powelli n.sp., differing in unspined hardly lobate angled periphery, very slight convexity above or below, and especially in having 12–14 chambers as against 9–10; size, 0.8 mm.
Type from Oneroa, Waiheke Island (5041), dominant there; also at Pakaurangi Point and Takaka.
Gyroidina allani n.sp. (Plate 28, figs. 134–136.)
Shell large for lineage, compressed, dorsally about 3 coils visible, about 11 chambers in last; sutures progressively more marked by grooves, medial area faintly convex; peripheral angle bluntly rounded, ventrally with wide umbilicus overhung by rim of little sharp plates projecting back from blunt bases of chambers Size, 1.3 mm.
Type from 5655. Index of Duntroonian-Waitakian (very abundant). The common Miocene form of this lineage is Gyroidina zelandica n.sp. (plate 28, figs. 138–140) (type from G.S. 1240, Island Creek, Ihungian), which is smaller than allani, flat above, conic below, with similar smoothed appearance dorsally, smaller umbilicus with angular rim of chamber bases and 8 chambers per coil (never more than 9); size, 0.9 mm. Whaingaroan and probably Kaiatan forms seem inseparable, and the species appears to reach Opoiti. The
Mahoenui form is identical, but the common Taranakian species is small, with much more open umbilicus (due to its greater width and the much smaller basal pads) with a rim of less knobbed chamber ends; it may be named Gyroidina stineari n.sp., the type being from 5638, Tongaporutu beds of Whangamomona region; it begins with the Mokau and reaches Waitotaran. A similar non-compressed form from the Eocene is Gyroidina scrobiculata n.sp. (plate 28, fig. 137) (type from 5068, Burnside Marl, Tahuian); like zelandica in all respects except for strong dorsal excavation of chambers and coil separation, both continued far back; known only from Tahuian and Upper Bortonian. All these forms are evidently less related to soldanii (rare here) than to altiformis R. E. and K. C. Stewart, but that Californian species has an open umbilicus with weak pads, and more chambers, quite differently hollowed on top. A quite different lineage, not so easily divisible into stratigraphic spcies, is that of G. neosoldani Brotzen and its allies, which is even more common throughout the Tertiary.
Asterigerina waiareka n.sp. (Plate 29, figs. 144, 145.)
Large, disc-like, very compressed; dorsal surface obscure, but at least 3 coils with 22–24 chambers, sutures oblique to spiral at 45°, straight; ventrally with sinuous complicated sutures, points of chambers recurved near outer edge. Size, 1.7 mm.
Type from 5064, Lorne; common here and in basal Kaiata beds, rare in higher part of Lower Ototaran. Index of Kaiatan, especially basal part. Somewhat like choctawensis C. and McG., 1938 (U.S.G.S. Prof. Paper 189D, p. 111, pl. 28, fig. 2), of Alabama Oligocene, but much larger, more compressed, with more chambers and coils.
Asterigerina lornensis n.sp. (Plate 29, figs. 146, 147.)
Much smaller and thicker than waiareka, with few chambers, subequally biconvex, surface obscure, about 2 dorsal coils with about 7 chambers, sutures very oblique, lightly convex; ventral pattern of chambers star-shaped, about 7 broad arms, the points almost at periphery. Surface somewhat undulating, irrespective of chambers. Size, 0.7 mm.
Type from 5064, Lorne. Not seen elsewhere.
