108 ICHTHYOLOGIA OHIENSIS 



I add here a fine small fish, which I have never 

 seen as yet, but is said to live in the small streams 

 which fall into the Elkhorn and Kentucky. It is a 

 slender fish, only two inches long, compressed and 

 of a fine purple red. It may belong to this genus, 

 or to any other of this tribe. It is commonly called 

 Red-minny. 



XIX Genus. Flat-head. Pimephales. Pimephale. 



Body oblong, thick, and scaly. Vent posterior 

 nearer to the tail. Head scaleless, fleshy all over, 

 even over the gill covers, rounded, convex above and 

 short. Mouth terminal small, toothless, with hard 

 cartilagineous lips. Opercule double, three branchial 

 rays. Nostrils simple. Dorsal fin opposite the ab- 

 dominals, with the first ray simple and cartilaginous. 

 Abdominal fins with eight rays. 



A singular new genus, which differs from Catasto- 

 mus by the terminal mouth, hard lips, soft head, 

 simple dorsal ray, &c. The name is abbreviated 

 from Pimelecephales which means Flat-head. 



[II. 299] [jj] 52d Species. Blackheaded Flat- 

 head. Pimephales promelas. Pimephale tete-noire. 



Diameter one fourth of the length, body oliva- 

 ceous silvery, head blackish, snout truncated, and 

 with soft warts: fins whitish, dorsal with a large 

 irregular black spot at the anterior base, with eight 

 forked rays, and one simple shorter obtuse hard: 

 anal with eight rays ; lateral line flexuose and raised 

 at the base, tail lunulate. 



A small fish three inches long. It is rare and 

 hardly known by the anglers. I describe it from a 

 specimen taken with a hook baited with earth-worm, 

 by Mr. William M. Clifford, in a pond near Lexing-
