Uiihopsis chrosomus Jori>an (1877), Ann. Lye. Nat. Hist. N. Y. 333. 



Very abundant in the clear tributaries of the Oostanaula, Coosa, and 

 Etowah. In Cedar Creek, at Cave Spring, it is the commonest species 

 occurring in the clear, cold waters, with Codoma callistia and Xcnisma 

 HteWferum. None of our Cyprinidcc excel Hydrophlox chrosomus in deli- 

 cacy of coloration. It is of a clear hyaline-green above; clear silvery 

 below: a scarlet band straight from upper edge of opercle to caudal : 

 dorsal, anal, and caudal each with a scarlet bar. In this species, the 

 mouth is rather less terminal than is usual in tlie group called Mydrophlox.

Hybopsis xanocephalus Jordan (1877), Ann. Lye. Nat. Hist. 334. 



With the preceding, but i-ather less common. This species bears some 

 resemblance to the young of Codoma callistia.
