stated to be " found on all the Indian coasts, entering fresh 

 waters," it is very doubtful whether more than one species 

 are not included under this head. I found this fish through- 

 out the frestwater regions I examined, from the Punjab to 

 Cape Comorin, from Sind to the eastern extremity of Burma, and 

 even some way up the Himalayas, living and breeding in fresh 

 water, where their young were being reared. 



Then we have catadromous forms which I should locate 

 among those of the freshwater, but of these there are, so far as 

 I am aware, only the Eel. There are a considerable number of 

 anadromous forms, and these are not so easy to arrange as to 

 whether they are or are not to be considered freshwater or 

 marine fishes. Among anadromous forms we find some, as in the 

 Salmon of our rivers, which ascend to breed, and wherein the 

 young continue until they may be in a condition to propagate 

 their kind : these would rank among freshwater forms. Then we 

 have the Shad, which hkewise ascends rivers to breed, but the 

 youug do not appear to be raised in the rivers, unless in the 

 lower reaches, and these could hardly be termed freshwater fishes. 

 Similarly among the species in India, it may be questionable 

 whether the Scicena coitor may not be a simple anadromous form 

 wherein the young drops down to the sea ; but this I do not think 

 to be the case, as I have found the young in rivers far above 

 impassable weirs. In the following paper I have thought it 

 advisable to omit, as far as possible, my own observations made 

 among the fishes in India, as such have already been published, 

 and to give the opinions of others who have worked in the same 

 localities as field-naturalists, and whose records are the results 

 of what they have personally found. Following this course, I 

 think it possible to show that I was and am entirely justified in 

 placing the fishes 1 did among the Indian freshwater fish-fauna, 

 although they have, subsequent to the publication of my papers, 

 been rejected as such by Dr. Griinther, and that without any 

 comment or explanation being given for the course which he has 

 adopted. 



Dr. Griinther furnishes an elaborate list of the forms of fresh- 

 water fish inhabiting the Indian region (Introduction to the Study 

 of Eishes, p. 220), and of the Acanthopterygians as follows : — 



" Pekcina, Lates (also Africa)." — This first genus in India is not 

 a freshwater form, but found in the mouths of rivers, up which it
