FISHES OF THE ALABAMA BASIN. 47 



Genus CENTRARCHUS Cuvier & Valenciennes. 



15. CENTRARCnUS IRTDEUS (Lac.) C. & V. 



Specimens from Alabama Kiver, 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. 



Genus POMOXYS Rqfinesque. 



16. POMOXYS NIGROMACULATUS (Le S.) Girard. 

 Specimens from the Alabama Eiver at Montgomery. 



17. POMOXYS ANNULARIS Raf. 

 From Eound Lake near Montgomery. 



SCLENIIXE. 



Genus HAPLOIDONOTUS Rqfinesque. 



18. HAPLOIDONOTUS GKUNHIENS Rafinesque. 

 Abundant in the Oostanaula. 



OOTTIDJE, 



Genus POTAMOCOTTUS Gill. 

 19. POTAMOCOTTUS MERIDIONALIS (Girard) Gill. 



Potamocottus Carolines GILL (1861), Proc. Bost. Soc. Nat. Hist. 

 Potamocotius 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 zoplierus, carolince, and meridionalis, and, believing them 

 specifically identical, we unite them under the oldest name. 



APHODODERHm 



Genus APHODODERUS Le Sueur. 



(ApJiredoderus Le S. ; Stern otremia Nelson.) 



20. APHODODERUS SAY ANUS (Gilliams) DeKay. 

 Specimens from Alabama Eiver near Montgomery. The fish de- 

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

 ternotremia mesotrema, is undoubtedly a variation of this species.
