At the request of Dr. Annandale of the Indian Museum the 
author has examined a second collection of Mollusca from Lake 
Chilka, a report on which is given below. The first collection was 
made by Dr. Annandale and Mr. Kemp in 1913 and included 
thirty-four species of which twenty-one were described as new,! 
though two of these (Velovita satbaraénsis and Tornatina soror) 
have from the examination of considerable further material 
proved to be unworthy of retention, as will be seen later. The pre- 
sent collection was made by the same collectors during Septem- 
ber and December of 1913 and January, February, March, July 
and September of 1914, and contains sixty-seven species of which 
twenty-five appear to have hitherto escaped notice and are described 
and figured in the present report, the type specimens in all cases 
being returned to the Indian Museum. This large number of new 
forms in both collections may be accounted for by the fact that 
practically no systematic collecting has ever been previously done 
in the lake. 
As was to be expected a large proportion of the species origi- 
nally recorded are again included in this second collection, some 
however very sparingly while others are conspicuous by their 
total absence. This is largely because examples of some easily 
recognized species were not sent. 
In conclusion the author would take this opportunity to 
express his thanks to Mr. E. A. Smith, I.S.O., for much help 
ungrudgingly given in the generic determination of the smaller 
Pelecypods of which both collections contain a large number.
