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

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



Ceratichthys.

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



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

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

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

 IG) 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.
