1 32 CONTRIBUTIONS TO NORTH AMERICAN ICHTHYOLOGY — III. 



I have not seen this species. From Professor Cope's description, it 

 would appear to he allied to 31. alMim, but distinguishable by the 

 longer head. It is a large species, abundant in the Yadkin Eiver, where 

 it is used for food.

This species is one of the most widely distributed species, although 

 it does not seem to be as abundant in individuals as several others. 

 There is considerable variation in form among different specimens, but 

 all the species with long dorsal fin and small /^-shaped mouth appear 

 to belong to one species, for which the name velatum should be retained. 



The finding of a species with unequal caudal lobes renders it evident 

 that the identification of Eafinesque's anisurus with this species is in- 

 correct. The name next in order is velatus Cope. The difference in 

 the size of the eye between collaijsus Cope and velatus Cope appears to 

 be due to difference in age merely. Younger specimens have the eye 

 proportionally larger.
