with ft woodcut representing the shell, the animal half contracted, buccal

above the mucous pore. [This may be regarded as a modification of thd 
abruptly truncated hinder end of the foot of Ndnina, the buccal plate or jaw 
and the teeth agreeing also with that genus.] ^

to belong to Nanina. The combination of Helix castra and sanis with infren-

self to be a printer’s error. Ibid. p. 104.

H. Adaihs, Proc. Zool. Soc. 1865, p. 408.

distinct group of Hynlina, the type of which would be Helix hitineata.
