Genus GrILA Baird & Girard. 



(Subgenus CLINOSTOMUS Girard.)

Leuciscus vandoisulus C. & V. (1844), Hist. Nat. Poiss. xvii, 317. 

 Clinostomus affinis GIRARD (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 Keedy Eiver than 

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

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

 genus. In the males, 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 Gilo, (Clinostomus) 

 funduloides have been well given by Professor Cope (Jouru. Ac. Nat. 

 Sci. Thila. 1868, 228). 



Genus NOTEMIGONUS Rafinesque. 



22. NOTEMIGONUS AMERICANTJS (Linn.) Jordan. 



Notemigonus ischanus JORDAN (1877), Ann. Lye. Nat. Hist. p. 364. 



This is the true Cyprinus americanus of Liunasus, as has been else- 

 where shown. We obtained but a single specimen in the Keedy 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. labrosus (Cope), but apparently 

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



Body long and slender, not much compressed, the depth about 4J (5 

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

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

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