Dr. Annandale visited the Chilka Lake during the last two 
weeks of November 1914, in order to continue his enquires into 
the fauna of this area. I had the pleasure of accompanying him, 
and the parasites described in the following paper were collected 
during the investigations. 
The fish from which the parasites were taken were caught in 
an otter-trawl about two miles east of Rambha. They appear to 
feed principally on prawns and crabs. 
A number of small rays (Trygon imbricata) were also caught 
and examined, but no parasites were found. This species appears 
to feed on small crustaceans and on thin-shelled molluscs. 
The little cormorant was shot on the shore of the lake near 
Rambha, and the pochard ( Nyroca ferina) was shot in a swamp 
neat Nalbano Island. 
Other birds and fish were examined but no parasites were 
found. 
The collection is an interesting one, but possesses no out- 
standing or distinctive features.
