"It is a giant, yet modified, form of A. nagaensis, from Asalu, 

 but it is more closely umbilicated and the costulation, for its 

 greater size, is much finer ; it is also more globose, and more 

 rounded at the apex." ( Godivin-Ansten.) 



The specimen figured is in the British Museum, received from 

 Col. Beddome, and is evidently a co-type.

 that it differs in form, sculpture, and colouring. Godwin-Austen
