A glance through Mr. Dover’s bibliography will “aha that 
most of the recent work on the fresh- and brackish-water 
fauna of India has been undertaken and published in India, 
_ and a very large proportion in Calcutta. Ever since Buchan- 
an’s investigation of the fishes of the Ganges over a century 
ago Calcutta has been, with brief intervals, a centre of studies 
ef the kind. The possibility of their existence in India has 
been denied in England, but litiera scripta manet. The names 
and the papers of McClelland, Benson, Nevill, Stoliczka, Ander- 
son, Wood-Mason, and Alcock are there to attest the succes- 
sion and we of the present generation can only hope to be 
numbered with these men 
do not propose to ‘discuss in detail the additious made 
to our knowledge of purely taxonomic zoology. In this res- 
pect Mr. Dover’s bibliography speaks for itself. I have, 
however, given a summary of the more important results 
ef a general nature arising from investigations of a more 
eomprehensive kind. Applied zoology is best left to those 
whose duty it is to apply the results obtained from pure 
pe a fogs ds and I have not attempted to discuss it 
8, however, included in his Sibtonrach references 
to all ‘appropriate works available on fisheries and medical 
zoology published in the period under review. In parasitology. 
however, he has included only those papers which deal with 
parasites that pass some part or the whole of their life- pee 
in aquatic animals other than insects. 
The decade has been prolific in reports on the fauna of 
particular localities and types of environment in India and 
neighbouring countries. Two quarto ae neither of which 
is yet complete, may be mentioned firs They are (i) the 
report on the fauna of the Chilka take that forms volume 
V of the Memoirs of the Indian Museum, and, (ii), volume 
VI of the Memoirs of the Asiatic Society of Bengal, in which 
are embodied the zoological results of a tour in the Far Kast. 
(i.e. in Japan, China, Siam and Malaya) undertaken in the 
years 1915 to 1916. 
The report on the Fauna of the Chilka Lake is based 
pene on setcstientions carried out in 1914 by Dr. 8S. W. Kemp

great and often sudden changes in the composition of the 
water in which they live. Many groups are represented in the
