HuTTON. — On some Pulmonate Mollusca. 153 



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. (PI. 

 in., fig. E.) 



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 

 vovoseekmdica 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 Testaeella. 



Paeyphanta busbyi. 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 (PI. IV., fig. l). The teeth 

 are 50-0-50. They are all aculeate, and similar, with simple bevelled tips 

 (PI. 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 

 behind, the margin produced, and waved. I could see no sign of a caudal 

 gland. 



It is evident that this genus should be placed in Vitrinince, near Daude- 

 bardia. 



Helix fatua, Pfeifer. The jaw is arcuate, slightly attenuated at the 

 ends, composed of about twenty imbricating plates ; its outer surface is 

 rough, with horny hair-like papillse, which form a fringe round the lower 

 margin. (PI. III., fig. n.) 



The radula is '007 inch in breadth. The transverse rows of teeth form 

 an obtuse angle of about 200°, salient posteriorly. (PI. IV., fig. n.) 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 

 marginals ; its length gradually decreases from the central row outward.
