reaching the posterior margin, the cutting point projecting beyond it. 

 Marginals broader than long ; the inner with three cutting points ; the 

 three outer very broad, with two small points at the inner corner. 

 Hab. Eangitira Bush, Temuka (C. Chilton). 

 The shell is hairy, but the hairs rub off when the animal is dead. 

 Helix zealandle, Gray. PL x., fig. e. 



Jaw arcuate, flatly ribbed, the ribs indenting the concave margin. 

 Dentition, 35-1-35 ; varying from 27 to 40. Laterals about 9 ; varying 

 from 8 to 10. 



Central tooth rectangular, the length more than twice the breadth ; the 

 reflexed portion half the length of the base, slightly constricted and with a 

 moderate point. The inner laterals like the central tooth, but broader and 

 with the outer lobe more marked and notched, the notch getting gradually 

 less outwards. Inner marginals with a long base and a short reflexed 

 portion bearing a long oblique cutting point on the inner edge and a small 

 cusp on the outer ; outer marginals irregular, the breadth and length about 

 equal, with a long oblique cutting point. The laterals pass gradually into the 

 marginals, and the cutting point is longest in the middle of the marginals. 

 Hab. Auckland (T. F. Cheeseman). 

 Helix antipoda, Hombron and Jacquinot. PI. x., fig. f. 

 Animal with the foot narrow, produced behind the shell ; a caudal 

 papilla and a mucous gland below it. Mantle subcentral, slightly reflected 

 over the peristome of the shell. Colour pale grey, the anterior portion 

 darker ; peduncles and a line down each side of the head dark blue-black ; 

 mantle pale grey with dead white spots. 

 Jaw like that of zealandice. 



Dentition, 35-1-35 ; varying from 31 to 36. Laterals about 12. 

 Central tooth rectangular, its length more than twice its breadth ; the 

 reflexed portion about half as long as the base, slightly constricted at about 

 a third of its length, the point moderate. The first five or six laterals like 

 the central tooth ; the others oblique, with a large cutting point on the 

 inner edge of the reflexed portion, and a small exterior cusp. Marginals 

 with a small irregular base, and a long oblique cutting point, increasing in 

 length to about the middle of the marginals and then decreasing. 

 Hab. Grey mouth (E. Helms). 



The shell varies very much in colour, sometimes being painted with 

 alternating oblique narrow bands of yellowish white and rufous, some- 

 times almost entirely rufous, or pale brown. 



Thalassia (?) peopinqua, Hutton. PI. x., fig. g, and pi. xi., fig. v. 

 Jaw arcuate, not tapering, with about 22 flat ribs, which slightly indent 

 the concave margin. 



Dentition, 31-1-31. Laterals 12.
