ERYTHRINUS. 

 In this place we have ventured to arrange the 

 genus Erythrinus, in variation to previous systems. 

 Exteriorly, with the exception of the mouth, many- 

 species are Carps in appearance ; but the structure 

 of the mouth, and the pancreatic appendages to the 

 stomach, ally them to the Salmons ; while the spot- 

 ting of some, and banding on the fins in others, 

 remind us of both the Trouts and the Graylings. 

 The last form prepared us for the want of the 

 second dorsal fin; and in one which could be 

 placed at the limits or commencement of a family, 

 we should expect either a small development or 

 total want of this accessary character.
