equal, and the middle cusp with a large point projecting beyond the pos- 
terior margin; in the outer laterals the inner cusp becomes obsolete. 
Marginals broader than long, with three points; the last without points, 
and the penultimate with only two points. 
Hab. Hawke’s Bay (W. Colenso). 
The shell in this species differs from that of P. coma in having the ribs 
nearer together and the spire more elevated. 
PaTuLA BUCCINELLA, Reeve (= gamma, Pf.). PI. ix., fig. p. 
Jaw finely striated, with a slight median projection. 
Dentition, 10-1-10.  Laterals 8 or 4. 
Central tooth rectangular, longer than broad ; the reflexed portion less 
than half the length of the base, tricuspid, the middle cusp with a short 
cutting point. The first three laterals like the central tooth, but the 
reflexed portion longer and the cutting point reaching the posterior 
margin of the base. Marginals broad, the inner ones with a bidentate 
cutting point at the inner corner; the last tooth minute, without any 
cutting point. 
Hab. I have examined the dentition of three individuals from Auck- 
land, and found it alike in all. 
The shell in this species is broadly umbilicated, but the umbilicus varies 
a good deal; the spire is flat and the interstices between the ribs finely 
striated with growth-lines. 
PATULA ANGUICULUS, Reeve (= theta, Pf.)? Pl. ix., fig. E. 
Animal like that of coma ; darkish-grey, the foot white with a grey patch 
on the back behind the shell. 
Jaw membranous, very delicate. 
Dentition, 11-1-11.  Laterals 5. 
Central tooth rectangular, the base as broad as long; the reflexed por- 
tion, tricuspid, the median cusp covering about two-thirds of the base and 
swollen at the end. The first two laterals are like the central tooth, but 
more elongated, and the median cusp reaching nearly to the posterior 
margin of the base: the outer laterals have a small cutting point on each of 
the side-cusps. Inner marginals with three points; outer marginals very 
broad and with 4 or 5 points. 
Hab. Greymouth (R. Helms). 
As I do not feel sure about the identification of this species I give a 
description of the shell. 
Shell very broadly umbilicated, the spire almost flat: whorls 44, with 
nearly straight ribs, about 80 or 85 in the tenth of an inch, the interstices 
finely reticulated : aperture sub-vertical, lunately sub-circular, Colour dark 
reddish-brown, banded with horny. Greatest diameter ‘1; least ‘07.
