MOLLUSCA OF IXDIA. 1271 



" Tlie form named ramriensia (but never described) is sligbtly 

 larger, uieasaring 1U| mm. in diameter, and lias a rather larger 

 mouth, but, as suggested by Nevili, is not distinguishable." 



Localities. Kumah Hill near Sandoevay, Arakan (Theobald) ; 

 Eamri Island, Arakan Coast ( W. T. B.). Shell ligured. 



A well-mai-ked species, somewhat resembling 21. suhjeda in 

 shape. 



I have not seen the type shell of M. l-umaJiensis, it is in the 

 Indian Museum, Calcutta, but tbere is a single specimen in the 

 Natural History Museum from the typical locality, which came 

 out of Mr. Theobald's collection ; it agrees well with the specimens 

 from E,;imri Island. 



The shells included by Nevili from the Dafla Hills, Assam, and 

 Bhamo, are different species ; they have been sent home and have 

 been identified by me.
