24 COKTRIBUTIOXS TO NORTH AMERICAN ICHTHYOLOGY HI. 



Genus GILA Baird <& Girard. 



(Subgenus CLINOSTOIMUS Girard.) 



21. Gila vandoisula {Cuv. & Val.) Jor. 



LeiiC'scus vandoisulus C. & V. (1844), Hist. Nat. Poiss. xvii, 317. 

 Clinostomus affinis Girakd (1856), Proc. Ac. Nat. Sc. 212. 



This species is common in the Saluda waters, as in the Catawba, 

 Yadkin, and other Southern streams. It seems to prefer still, or even 

 muddy waters, as we found it more abundant in the Eeedy River than 

 in either Saluda or Enuoree. Our specimens were greenish or bluish 

 in color, the back mottled with scales of a different hue, as usual in this 

 genus. In the mules, the region behind the head and above the pec- 

 torals and extending backward to the anal are of a bright rosy-red, 

 brightest just*behind the head. There is no distinct dark lateral band. 

 None of our specimens were noticed to be tuberculate. The characters 

 distinguishing this species from the more northerly Gila {Clinostomus) 

 funduloidcs have been well given by Professor Cope (Journ. Ac. Nat. 

 Sci. Phila. 1868, 228). 



Genus NOTEMIGONUS Rafinesque. 



22. NOTEMIGONUS AMERICANUS {Linn.) Jordan. 



Notemigonus isclianus Jordan (1877), Ann. Lye. Nat. Hist. p. 364. 



This is the true Cyprinvs americanus of Linnseus, as has been else- 

 where shown. We obtained but a single specimen in the Reedy River. 

 Professor Cope found it abundant in the sluggish waters of the Catawba. 

 The long anal, more compressed body, larger eye, and peculiar breeding 

 colors distinguish this species from the Northern and Western N. 

 chrysoleucus. 



Genus CERATICHTHYS Baird. 



23. CERATICHTHYS ZANEMUS, sp. nov. 



A small, peculiar species, allied to C. labrosns (Cope), but api)arently 

 differing in the longer barbel, smaller scales, and in the coloration. 



Body long and sJender, not much compressed, the depth about 4^ (5.^ 

 in young) in length. Head rather long, narrow^ and pointed, 4^ iu 

 length, very slender in young specimens, stouter in adults : snout de- 

 curved in protile, with an angle in front of the nostrils. Eye moderate,
