S. crassiuscuh, Benson." It certainly approaches that species in 

 several respects, but the last uhorl does not increase so rapidly 

 and the spire is more produced. • j •/ 



Several specimens fro>n Bombay measure 13o mm. in diameter 

 thus exceeding the type which is in the Cuming col ection Ihree 

 shells from Calcutta in the Theobald collection also have a dian.eter 

 of 13 mm. On the other hand three specimens m the Britisli 

 Museum collected in 1880 by Col. Wilmer on brickwork at Fort 

 William, Audaman Islands, which 1 refer to this species, do not 

 exceed 9 mm. and a still smaller form, collected by hira at lort 

 William, Calcutta, only measure 6-5 mm. The shells collected 

 bv the Stanley Gardiner Expedition, in the MakUye group— 

 which are also in the British Museum— belong to a rather slender 

 form, pale greenish corneous, and almost transparent.

Type in the British Museum. n ^ ^^- 



The British Museum contains four specimens trom Calcutta 

 labelled Succinea mhyranosa, but which differ from that species by 

 the more slender spire and in being of a pale amber colour. Ihe 

 new species has also some relationship with .S'. bensom, but the 

 aperture is less high in proportion to the spire. One ot the 

 specimens has 3^ whorls completed and measures nearly b mm.
