214 DR. A. GUNTHER ON THE COLD-BLOODED [May 28, 



have not been marked by Hamilton as Nepalese, and Mr. Hodgson's 

 collection, again, being composed of species which, although known 

 to Hamilton and M^'Clelland as occurring in other parts of East 

 India, are new to the fauna of Nepal. But the most interesting fact 

 disclosed by these collections is, that several fishes which have been 

 considered as strictly marine forms, and the congeners of which cer- 

 tainly are exclusively inhabitants of the sea, ascend the rivers as far 

 as Nepal. It is much to be regretted that Mr. Hodgson's collection 

 of specimens of Fishes is not as extensive as those which he has made 

 in other branches of zoology. Several of the drawings have been 

 evidently taken from species unknown ; yet beautifully as they are 

 executed with regard to their natural coloration and their general 

 form, it would be very hazardous to attempt to introduce them into 

 the system with technical denominations, as the specific distinctions 

 of Fish are chiefly based upon characters (fin-rays, teeth, number 

 of scales, &c.) to which due attention is never paid in drawings exe- 

 cuted by a person ignorant of ichthyology.
