FISHES OF THE ALABAMA BASIN. 47 



Genus CENTRARCHUS Cuvicr £ Valenciennes. 



15. CENTRARCHUS IRTDEUS {LctC.) C. & V. 



Specimens from Alabama Eiver, at Montgomery, similar to others 

 from the Neuse and from about Charleston. This species has been 

 found by Prof. S. A. Forbes in Southern Illinois.

19. POTAMOCOTTUS MERiDiONALis {Girard) Gill. 

 J'otamocottus caroUvce Gill (1861), Proc. Bost. Soc. Nat. Hist. 

 PoiamocoUus zoplierus 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 zojpJienis, carolinw, and meridionalis, and, believing them 

 specifically identical, we unite them under the oldest name. 



APHODODERID^. 



Genus APHODODERUS Le Sueur. 



{Aphredoderns Le S. ; Sternotremia Nelson.) 

 20. APHODODERUS SAY" ANUS {GUliams) 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.
