446 INDIAN CYPRINID^. 



Before I was aware of the position and number of the scales selected 

 by M. Agassiz for examination, most of the plates were finished ; and to 

 give separate ones of three scales from each species would have increased 

 the bulk and expense of the paper beyond the measure of any equivalent 

 advantage. The scales which are represented on the annexed plates were 

 therefore selected from the posterior third of the body, about half way be- 

 tween the dorsal and caudal fins, where they appeared to bear the nearest 

 relation to the general form of scales on other parts of the body. When a 

 second scale is given, it has always been taken from between that situation 

 and the dorsum.
