Notes on Plankton from the Chilka Lake. — The tow- 

 nettings on which the following notes are based were taken by 

 Dr. Annandale and Mr. Kemp on the surface of the Chilka Lake 

 off Barkul in the Puri district of Orissa in July, 1913- 



Of three samples that I have examined, the first contained 

 only a number of immature Mysids, and a small quantity of 

 detritus. The remaining two samples, however, contained a cer- 

 tain number of planktonic organisms.
