Potamocoitus carolivce Gill (1861), Proc. Bost. Soc. Nat. Hist. 

 Poiamocoltus zopherus Jordan (1877), Ann. Lye. Nat. Hist. N. Y. 320. 



Exceedingly abundant in all the clear and cold tributaries of the 

 Etowah, Oostanaula, and Coosa. Many specimens from the cold waters 

 of the Cave Spring Creek. We are unable to satisfactorily distinguish 

 the forms called zopJiertis, carolince, and 7neridionaUs, and, believing them 

 specifically identical, we unite them under the oldest name. 



APHODODERIDiE. 



Genus APHODODERUS Le Sueur. 



( Aphredoderiis lie S. ', Sternotrcmia 'Nelson.) 

 20. APHODODERUS SAY ANUS [GilUams) DeKay. 

 Specimens from Alabama River near Montgomery. The fish de- 

 scribed by Professor Jordan from Flint River, under the name of As- 

 ternotreinia mesotrema, is undoubtedly a variation of this species.
