Brookula funiculata n. sp. (Plate 53, figs. 5a, 5b, 5с.) 
Shell minute, thin but not very fragile, depressed-turbinate (same 
prominent, almost straight but sloping ы backwards, $ a little "d 
on base; interstices of variable width, usually 14-2 width o 
They contain exceedingly fine and generally very dare ird low dd 
rounded, only a small fraction of axials in width, interstices linear. The 
axials continue very prominent on base till about two-thirds across, when 
they suddenly diminish in width and height and turn in towards umbilicus, 
thus marking off the edge of a funicle surrounding umbilicus, and this 
edge, though often very indistinct, is never wholly wanting; it is most 
prominent on juvenile shells. The funicle is about one-third the major 
diameter, and at its bottom lies umbilical perforation, which is moderately 
After about 1$ whorls from aperture axials very rapidly become obsolete, 
so that protoconch (11 smooth globular whorls) is only indistinctly marked 
off from following whorl. Spire approximately the same e ep as aper- 
ture, lightly convex, angle about 90° or more. orls 31, regularly 
increasing, not tightly wound, but not so loose as in Lvotella polypleura 
(Hedley), body-whorl and base narrowly convex; upper whorls being raised, 
view from above showing a strongly turbinate shape.  Suture deep. 
Aperture almost free, subcircular, with faint rounded angulation above, 
peristome continuous, columella arcuate, not reflexed. 
Holotype: Height, 0-8 mm. ; length, 1 mm. Largest specimen: Height, 
0-95 mm. ; length, 1-2 mm.

so that interstices may be up to three times ен width. This shell has 
much resemblance to some species of Liotella ; it differs from L. сеек 
снесет in tenia of aperture, axial ribs, interstices, and umbilicus, an 
from L. rotula (Suter) in turbinate shape and different umbilicus. ' Also 
related to shell next described. The record of L. polypleura (Hedley) from 
Castlecliff beds possibly refers to this species. The author has examined 
a considerable number of Wanganui minutiae, and, though this Brookula 
is common (though only in occasional patches, especially in the matrix 
round corals), no specimens of true Liotella or Liotina have yet е found. 
Brookula pukeuriensis n. sp. (Plate 53, figs. 3a, 3b, 3c.) 
hell minute, very t thin and fragile, к, perforate, 23 axials on 
last whorl in each of the three shells examined, prominent but thin 
and sharp, curved forward on periphery, slightly sinuate on base; inter- 
but distinct iid ае directly after Piototooh ; they vds over base and 
thin out quite regularly on nearing umbilicus. Perforation semi-perspec- 
tive, without surrounding funicle ; its circular outline hardly реа 
by inner lip, central, and about one-quarter of major diameter. Spire 
about the same height as aperture, its angle a little less than 90°. Whorls 4,
