FISHES OF THE ALABAMA BASIN. 53 



Genus NOTROPIS Bqfinesque. 

 38. NOTROPIS LIRUS Jordan. 



Nototropis Urns JORDAN (1877), Ana. Lye. Nat. Hist. N. Y. 342. 



Common in tributaries of the Etowah, Oostanaula. andCoosa in still r 

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

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

 resembles the species of LytJirurus, from which it is technically separated 

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

 approaches it in the small size of its scales. 



39. NOTROPIS STILBIUS Jordan. 



Nototropis stilbius JORDAN (1877), Ann. Lye. Nat. Hist. N. Y. 343. 



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

 genus greatly need revision. 



Genus NOTEMIGONUS Eafinesque. 



40. NOTEMIGONTJS CHRYSOLEUCUS (Hit.) Jor. 



(Stilbe americana of most writers ; not Cyprinus americanus Linnaeus, 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. 



Phenacoliw catostomus JOBDAN (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 (Girard) Jordan. 



Hybo2)sis mncTielli GIRARD (1856), Proc. Ac. Nat. Sc. Phila. 1856, 211. 

 Ceratichthys hgalinus COPE (1868), Journ. Ac. Nat. Sc. Phila. 1868, 236. 



Very common in the Alabama Basin. C. liguttatus 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.
