source. Sowerby’s Catalogue, or at least the part dealing with 
the Indian species, was published prior to Kobelt’s work. It 
is a very useful vompilation, but is, at least for the Indian 
species, in no sense critical. The last and the most recent 
revision of the Indian species is that by Preston published in 
his volume! on the Freshwater Gastropod and Pelecypod 
Molluses of India. It is, unfortunately, nothing more than a
