FISHES OF THE ALABAMA BASIN. 53 



Genus NOTROPIS Uafinesqiie. 

 38. NoTROPis LiRus Jordan. 



Nototropis Virus Jordax (1877), Add. Lye. Nat. Hist. N. Y. 342. 



Common in tributaries of the Etowab, Oostauaula, and Coosa in still, 

 deep waters. This species is not, by any means, a typical member of 

 the genus. In form, coloration, squamation, and nuptial tubercles, it 

 resembles the species of LytJir tints, from which it is techTiically separated 

 by the want of masticatory surface on the teeth. Notropis matutinus 

 approaches it in the small size of its scales. 



39. NoTROPis STiLBius Jordan. 



Notofropis sfilbius Jordan (1877), Ann. Lye. Nat. Hist. N. Y. 343. 



Abundant in the water-basin of the Alabama. The species of this 

 genus greatK' need revision. 



Genus NOTEMIGONUS Bafinesque. 



40. NOTEMIGONUS CHRYSOLEUCUS (Mit.) Jor. 



{Stilbe americana of most writers; not Ct/prinusamerica)ms'Linu[sns, which is a Southeast- 

 ern species — Notemigonus ischanus Jor.) 



This familiar species is very abundant in bayous and weedy streams 

 in the basin of the Alabama. 



Genus PHENACOBIUS Cope. 



41. PHENACOBIUS CATosTOMUS Jordan. 



PhenacoMus catostomus Jordan (1877), Ann. Lye. Nat. Hist. N. Y. 332. 



This strongly marked species was found in abundance in two clear 

 streams. Silver Creek and Cedar Creek, tributaries respectively to the 

 Etowah and the Coosa. This is a much stouter species than P. uranops 

 Cope ; it has less developed lips and is in various other ways dissimilar. 



Genus CERATICHTHYS Baird. 



42. CERATICHTHYS WINCHELLI {Oirard) Jordan. 



HijUpsis winchelli Girard (1856), Proc. Ac, Nat. Sc. Phila. 1856, 211. 

 Ceraiichthys hyaUnus Cope (1868), Journ. Ac. Nat. Sc. Phila. 1868, 236. 



Very common in the Alabama Basin. C. higuttatus was not obtained 

 by us in any of the tributaries of the Alabama. It seems, however, to 

 have been described by Girard, from the Black Warrior, under the name 

 of Nocomis bellicus.
