We have substituted the name Alburnops Grd. for the earlier name 

 Hybopsis, as we think that the latter genus was founded on a species of 

 Ceratichthys. 



15. Alburnops chlorocephalus (Cope) J. & B. 



Hyhopsis chlorocephalus Cope (1870), Proc. Am. Pbilos. Soc. 461. 



This beautiful little fish is abundant in the clear rapid waters of the 

 Saluda. It resembles //. rubricroccns. but is smaller and stouter-bodied, 

 with smaller mouth. The scales in front of the dorsal are fewer (about 

 16) in number. The teeth are 1, 4-4, 1 (2, 4-4, 2, in rubricroceus). The 

 male specimens are profusely tuberculate on the snout and ante-dorsal 

 region. Professor Cope found this species abundant in the clear waters 

 of the tributaries of the Catawba.
