I am indebted to Mr. Kemp for the above list of records for 

 this species and for samples of specimens from nearly all the 

 localities, from which I have been able to confirm Mr. Kemp's 

 determinations. When forwarding the list of captures, Mr. Kemp 

 kindh' gave me the following note on the general occurrence of 

 this species. "The species usually occurs in enormous numbers 

 swimming in shoals. In one instance, when a strong breeze was 

 blowing, it was noticed that the shoal kept to the windward side 

 of the pond. In the neighbourhood of Calcutta, it seems to prefer 

 ponds and canals, of slowly moving water, which are brackish, but 

 does not occur in the salt lakes proper. None the less, as shown 

 in the records given above, it is sometimes found in water almost 

 or fully as salt as the sea and the fresh water record from a pond 

 in the Zoological Gardens at Calcutta, cannot be questioned." 



Since writing the above, Mr. Kemp forwarded to m2 specimens 

 from Madpur, in the Midnapore district from absolutel}^ fresh 

 water, " at least thirty miles away from the nearest possible source 

 of saline contamination ' ' 



The spejies was taken iti abundance at all the above localities. 



We may therefore summarise our knowledge of the distribu- 

 tion of this species by saying that it is an abundant form at the 

 head of the Bay of Bengal and on the east coast of India, from 

 Chittagong and the delta of the Ganges to Vizagapatam, usually 

 found in brackish water or in fresh water not far distant from the 

 influence of brackish tidal streams, but occasionally found in abso-
