"This shell is an interesting ally of A. khasiacus, from which it 

 differs in its thick, well-ribbed epidermis, but more especially in 

 the very different form of the operculum, «hich in khasiacus 

 is quite smooth and concave in front. It is also a smaller and 

 more delicately formed shell." [Godwin- Austen.)
