Hutton. — On New Zealand Land Shells. 165 



Hab. Greymouth (E. Helms). 



The surface of the shell between the ribs is finely reticulated. 



Patula ioniflua, Beeve ( = lambda, Pf.). PL x., fig. h. 



Animal with the mantle sub-central, slightly reflected over the peristome 

 of the shell : tail pointed, with a caudal mucous gland, but no papiUa ; eye- 

 peduncles approximated at their bases. White, with clusters of brown 

 spots and an interrupted brown line round the sides, below which the 

 margin of the foot is striped with brown and white transverse bands ; a 

 streak on each side of the head black ; sole of the foot mottled with brown, 

 arranged in irregular transverse bands, which slope backwards and form an 

 obtuse angle in the centre. 



Hab. Eangitira Bush, Temuka (0. Chilton). 



For the jaw and dentition of this species see Trans. N.Z. Inst., xiv., 

 p. 151. 



Patula tapieina, Hutton, PI. ix., fig. g. 



Animal like coma ; colour white ; peduncles, tentacles, and a stripe 

 down each side of the head purplish black. 



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



For the jaw and dentition of this species see Trans., N.Z. Inst., xiv., 

 p. 150 (P. coma). 



Patula pobtia. Gray. PI. ix., fig. t. 



Jaw arched, not tapering, with about 34 flat ribs, or plates.. 



Dentition, 24-1-24. Laterals about 9. 



Central tooth rather wedge-shaped, broader behind, longer than broad ; 

 the reflexed portion triangular, slightly constricted, not covering half the 

 base, the point small ; laterals rather oblique, broader than the central, the 

 reflexed portion bicuspid with a long point on the inner cusp. They pass 

 gradually into the marginals which are rather broader than long, with a 

 long cutting point, and a small one on each side of it. 



Hab. Auckland (Cheeseman). 



Patula venulata, Pfeiffer. PI. xi., fig. y. 



Jaw arched, with about 10 flat ribs in the centre ; the ends striated. 



Dentition, 17-1-17. Laterals 6. 



Central tooth rectangular, longer than broad ; the reflexed portion 

 tricuspid, the lateral cusps small and constricted on the outer side ; central 

 cusp reaching nearly three quarters of the length of the base, the cutting 

 point large. Laterals like the central, but broader, and the lateral cusps 

 with points, of which the inner is the larger. The cusps get smaller, and 

 the inner cutting point gets larger until the inner marginals have two, 

 nearly equal, points and a smaU outside point. The outer marginals have 

 the two points coalesced into a single bidentate point ; while the outer point 

 gets larger. The 17th marginal has only two small points.
