I have upt seen tliis species. From Professor Cope's descriptiou, it 

 \v(nil(l appear to l»o allied to M. aJhutn, l)ut distinguishable by the 

 longer bead. It is a large species, abundant in the Yadkin River, where 

 it is used lor food.

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

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

 There is considerable variation in foim among difterent specimens, but 

 all the species with long dorsal tin and small yy-sliaped mouth appear 

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



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

 that the identification of Rafinesque's anifsurus with this species is in- 

 correct. The name next in order is rcJatus Cope. The difl'erence in 

 the size of the eye between collojyfius Cope and rclatus Cope appears to 

 be dui' to diftVrence in age merely. Younger specimens have the eye 

 proportionally larger.
