FISHES OF THE ALABAMA BASIN. 53 



^ Genus NOTROPIS Rafinesque. 

 38. NoTROPiS LIRUS Jorflan. 



Notolroph Urns Jordan' (1877), Auu. Lye. Nat. Hist. N. Y. 342. 



Common in tributaries of the Etowab, Oostanaula, and Coosa iu still, 

 deep waters. This species is not, b^' any means, a typical member of 

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

 resembles the species o^ Lytlirurus, from which it is technically separated 

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

 approaches it in the small size of its scales. 



39. NoTROPis STiLBius Jordan. 



Nototropis stilbius Johdax (1877), Anu. Lj'c. Nat. Hist. N. Y. 343. 



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

 genus greath' need revision. 



Genus ^OTEUiGO^ U ^ Bqfinesque. 



e 

 40. NOTEMIGONUS CHRYSOLEUCUS (Mit.) Jor. 



{Stilbe americana of most writers ; uot Cyprinus americanus Liuiia;us, which is a Southeast- 

 ern species — Noiemigonus ischaniis 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. 



Phenacohius catoslomiis Jokdan (1877), Aim. Lye. Nat. Hist. N. Y. 332. 



This strongly marked species was found in abundance iu 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 CERATICIITHYS Baird. 

 42. Ceratichthys winchelli {Girard) Jordan. 



Hijhopsis winchelli GiitAKD (185G), Proc. Ac. Nat. Sc. Phila. 1856, 211. 

 Ceratichthys hyaliniis Cope (1868), Journ. Ac. Nat. Sc Phihi. 1868, 236. 



Very common in the Alabama Basin. G. 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.
