 in proportion to the last whorl, which is also much more tumid at 

 the base and has the basal margin more truncate.

"This species approaches S. semiserica, Gould, but is dis- 

 tinguished from that and from all other Indian species by its 

 coarse sculpture. It has also a larger spire than S. semiserica. 

 It is not common : indeed species of the genus Succinea are 

 generally but very locally distributed in India and Burma." 

 (Blanford.) 



Apparently a rare species not seen by me.
