five inner and two outer rows are simple, but those of the sixth to thirteenth 
rows are barbed, looking like the fluke of an anchor seen in profile. (Pl. 
IIl., fig. x.) 
The specimen from which the figures were taken was collected by Mr. 
T. Kirk, at Waiuku, in the Lower Waikato district. The animal was 
without its shell, but from the mark on the body it was easy to see that the 
shell was pauci-spiral, and on the hinder part of the body. As Daudebardia 
novoseelandica came originally from the Waikato, I presume that this is the 
same species ; but while the shape of the shell is that of Daudebardia, the 
teeth appear to belong to Testacella. 
Parypuanta Bussy1. There is no jaw. The radula is about an inch in 
length, and -4 inch in breadth at the anterior end, tapering to a point 
posteriorly, with about 104 transverse rows of teeth, the rows forming an 
obtuse angle of about 130°, salient posteriorly (Pl. IV., fig. z). The teeth 
are 50-0-50. They are all aculeate, and similar, with simple bevelled tips 
(Pl. IV., fig. A). The first five laterals are small. From the sixth they 
gradually increase in length to about the thirty-fifth, and then get smaller. 
This description is taken from a specimen, very well preserved in spirit, 
kindly given me by Mr. T. F. Cheeseman. The whole of the animal, in- 
cluding the sole of the foot, is dark blue-black. The upper surface is covered 
with rather large, flat, granulations. The foot is narrowed in front and 
_ the margin produced, and waved. I could see no sign of a caudal 
glan 
" is evident that this genus should be placed in Vitrinine, near Daude- 
bardia, 
Hux rarva, Pfeiffer. The jaw is arcuate, slightly attenuated at the 
ends, composed of about twenty imbricating plates; its outer surface is 
rough, with horny hair-like papille, which form a fringe round the lower 
margin. (Pl. IIL, fig. n.) 
The radula is ‘007 inch in breadth. The transverse rows of teeth form 
an obtuse angle of about 200°, salient posteriorly. (Pl. IV., fig. .) The 
teeth are 20-1-20. In all the reflexed part is very small. The central tooth 
has a single cusp, bearing a cutting point, with square projecting shoulders 
at its base; the base of attachment is rectangular, three times as long as 
broad, and two-thirds of its length projecting beyond the cutting point of 
the reflexed portion. All the lateral and marginal teeth are bicuspid, the 
cusps being equal, and each bearing a cutting point. The cusps gradually 
diminish in size outward until they can hardly be recognized in the outer 
marginals. The base of attachment of the inner teeth is rectangular, but 
becomes oblique in the outer laterals, and then gradually rectangular in the 
—— its length gradually decreases from the central row outward.
