ment issued, say once in ten years, the gratitude of ail inter- 
ested in fish and fisheries to Professor Bashford Dean and to 
the American National Museum, which has published the three 
volumes, wil) be perpetual. No ichthyologist, palaeontologist, 
piseiculturist or fishery expert can afford to be without these 
three volumes which should be supplemented for all those 
undertaking ichthy ological research by those of Professor David 
Starr Jordan. This is particularly true of India, in several of 
the colleges of which research on the anatomy of fishes is being 
undertaken with Day’s volumes in the ‘“‘ Fauna of British 
india’’ and the same author's “ Fishes of India’ as sole 
works of reference. Invaluable as these monographs of Day 
were in their Sia oS indispensable as they still remain, thay 
have, as is only natural, been superseded in many respects, by 
more recent seprirrese and to trust to them alone is to 
court disaster.
