Hal. I found this interesting species exceedingly abundant in 

 the tanks of Calcutta. It has recently been collected by my 

 servant, who accompanied Dr. Day on a trip to the upper waters 

 of the Ganges, at Hurdwar and at Roorkee, where it lives in the 

 river itself and in the contiguous ponds and marshes.

The largest specimen in my possession measures in a straight

 with two others at Singhur near Poona in running water. It was 

 in this neighbourhood also that M. Jacquemont collected his 

 specimens. Col. Sykes, in his account of the land-crabs of the 

 Dekhan, prefixed to Prof. Westwood' s description of the species 

 under the name of Thelphusa cunicularis, mentions its occurrence 

 in the same place, and in all the valle}^ and on the most elevated 

 tablelands of the Ghats at from 2,000 to 5,000 feet above the 

 sea-level, and is of opinion that it does not extend more than

 Blanford has, however, brought specimens from S. E. Berar, 

 west of Chanda, and I am indebted to Mr. V. Ball for examples 

 from near Cliota Nagpur. One of the Museum collectors lately obtain-
