This is a bright silvery species, very common about Calcutta, with the

been parched and dry for several months, I was surprised to see a number of 
persons fishing in the trenches of the Esplanade, which at first seemed to be 
quite unconnected with any ponds from which the fish could have come, but 
on inquiry, I found that they had ascended to the drains from a reservoir 
at some distance, from which the fish must have had a fall of several feet 
to surmount.
