Very abundant in all the tributaries of the Etowah, Oostanaula, and 

 Coosa Elvers.

Genus HYDROPHLOX Jordan 

 31. Hydrophlox chrosomus Jordan. 



Ilyhopsis chrosomus Jordan (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 Xenisma 

 stelliferum. None of our Cyprinidce excel Hydroplilox 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 the group called Hydrophlox. 



32. Hydrophlox x^nocephalus Jordan. 



Hyiopsis crcEnocephahts Jordan (1877), Ann. Lye. Nat. Hist. 334. 



With the preceding, but rather less common. This species bears some 

 resemblance to the young of Codoma callistia.
