regarded as complete, seeing that there are large tracts of the country, such as 

 Eajputana and the States of Central India, Hyderabad and Berar, the Central 

 Provinces and the small States between them and Chota Nagpur, and, last of 

 all, Mysore, where fresh- water crabs have been hardly touched by collectors. 

 It is of course possible, that in such dry parts of the country as those first 

 mentioned, fresh-water crabs may be scarce ; but in the little-explored jungle 

 tracts of the borders of Chota Nagpur and the Central Provinces they might 

 be expected to be abundant.
