Sowerby's description and figures of the t\-pe-shell of the 

 species are very poor; Adam's and vou Frauenfeld's description.s 

 also are no better; Benson's description, however, is excellent and 

 Hanley and Theobald published a good figure. 



Nevill gave the name perohvia to some specimens from Kathi- 

 awar, these specimens are subfossil, but do not materially differ 

 from the large series from various places to deserve distinct 

 varietal rank. We have not been able to trace the three speci- 

 mens from Arakan, Burma, which Nevill referred to as "var. 

 ( ? distinct sp.)." 



Preston wrongly identified specimens of this species as be- 

 longing to a new species, which he described under the name S. oris- 

 saensis, while the large series of specimens from the Chilka Lake 

 which he named S. minima is a very mixed lot of specimens of S. 

 blanfordiana and 5. {A.) miliacea. 



The specimens we now assign to this species are from the 

 Little Rann of Cutch at Kura, Kathiawar ; Bombay ; Ceylon 

 (t3-pe? of the species labelled originally '' St. ceylonica, n. sp. by 

 Nevill) and the Chilka Lake, in which it is abundant in thickets of 

 Potamogeton pectinatus.

Nevill' s description and the notes appended to it together 

 with the excellent figure in his second paper make the identifica- 

 tion of this interesting species an easy matter. 



The only specimens of the species in the collections of the 

 Zoological Survey of India are the types and a series of co-tj^pes 

 from Port Canning in the Gangetic Delta, but Nevill noted that the 

 species was also represented in the collections of Uohrn, Bed dome, 

 Theobald, Blanford and Hungerford.
