This is a second species of the remarkable sub-genus Lithotis, much 

 more tumid than the type Succinea (Lithotis) rupicola, and with ai 

 proportionally more developed spire ; it serves to connect that form 

 with the typical rock inhabiting Succinece of Western India, such as 

 S. Girnarica, Theobald, and a new species from Mahableshwar, 

 the animal of which is very similar to that of Lithotis. 



The specimens figured are not the largest that have been found. 

 Major Evezard possesses shells from Poorundhur measuring 9 

 millimetres in length, 6 in diameter, and 4 in height (when laid with 

 the aperture downwards). In these the sculpture is much less re- 

 gular and weaker, than in the accompanying figure which represents 

 a young specimen. The largest Singhur specimen in the same col- 

 lection measures 8, 6, and 3j millimetres in its 3 dimensions, the 

 aperture being 6 mill, by 4.
