44.6 INDIAN CYPRINIDZ. 
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.
