ALYCliUS. 223 



"This species is of the type oi" A. Oglei, of tlie iVoa Dihing Valley, 

 south of tlie Brahin.-iputni, but is far larger, more globose, with 

 a finer apex, and much stronger peristome. A. ahorensis is also 

 a close ally, but differs in form, slight crenulation, and the very 

 different costulatiou on the swell of the last whorl." (Godwin- 

 Austen.)

" In the extremely fine costulation of the swollen part of the
