V.—A LIST OF FISHES FROM LAKE CHILKA, TOGETHER WITH A 
DESCRIPTION OF A NEW SPECIES OF Gobius. 
The following list comprises two collections, one made by 
Mr. Hodgart, Museum collector, in the neighbourhood of Gopkuda 
Island in August 1907; the other by myself near Satpara in 
December 1908. 
Satpara lies at the landward extremity of the narrow channel 
which connects Lake Chilka with the sea, whereas Gopkuda is far 
removed from the entrance. 
On the way to the Lake (December 8th, 1908) three specimens 
of fish were purchased in the bazaar at Balgaon (B. N. Railway). 
These were identified as— 
NOTOPTERIDE. 
Notopterus kaptrat.
