258 F. Stoliczka — Notes on Terrestrial Mollusca. [No. 3, 



grow to a large size, and is always of a horny brown colour, 

 with the umbilical carina often white. 



The animal is dull white, with grayish pedicles and tentacles, foot 

 very narrow, the glandular appendage not very prominent. 



Hah. I only found forahilis on the limestone hills at Damotha 

 near Moulmein, where no other species of Sophina occurred.

Hah. On the limestone hills of the so-called ' Farm Caves,' on 

 the Ataran river and also on similar hills south of Moulmein. 



The depressed shape of this species, together with a compara- 

 tively large and strongly carinated umbilicus, readily distinguish 

 it from other Sophina. The specimens which I collected at the 

 Farm Caves and south of Moulmein are all of a uniform pale 

 straw colour, but I have lately received from Mr. Theobald a few 

 which were obtained further eastwards on the Ataran river, and 

 these possess a very distinct brown band above the periphery of 

 the last whorl (see pi. xix, fig. 12); there is, however, no other 

 specific difference between the two. 



Animal pale yellowish or brownish white, posterior end of the 

 foot about the gland generally tinged with gray.
