There is preserved in the Indian Museum a series of shells from 

 the old A. S. B, collection that Nevill' believed to be " probably 

 typical specimens from Hutton." These differ constantly from 

 the figure pubHshed in the '' Fauna " and cited above^ in tapering 

 less, in having the body-whorl less swollen and in the shape of the 

 aperture, which is more elongate and has the columellar and outer 

 margin more nearly equal in length. The specimens have the 

 sculpture we have described above well developed, though the shell 

 has usualh^ been described merely as smooth and polished.

Race barkudcnsis, nov. 



As we find that individuals from a small island in the Chilka 

 Lake differ quite constantly from what we take to be the forma 

 typica from the Ganges valley, and also from any of the forms 

 already described and relegated to the synonomy of the species, we 

 propose to describe the race as new under the above name. 



The shell is considerably narrower than that of the forma typica, 

 the proportions of breadth to height being i : 4"5 ; it tapers less and 

 has when mature 8| whorls; the apex is usually a little swollen 

 and the aperture is relatively smaller and narrower. The strucutre 

 and sculpture of the shell, however, are precisely similar to those 

 of the typical form.
