This species is merely mentioned by Prof. Agassiz,* and 

 does not seem to have been noticed by any other Ameri- 

 can author. My specimens show the following characters : — 



Head and body stout and heavy, the latter deep and compressed, the 

 depth being about 5 in the length in the larger specimens. Head and 

 mouth much as in Alvordius asjyro, but heavier, and the mouth rather nar- 

 rower: intermaxillaries slightly projectile, but the skin of the middle of 

 the upper lip continuous with that of the forehead, as in Percina. Eye 

 moderate, 4 in head. Head about 4 in length, without caudal. 



Scales rather large, 58 in the lateral line, which is continuous; median 

 line of the belly, and the whole chest, covered with small scales. 



Fins all larye; dorsals slightly connected by membrane at the base; 

 the second dorsal" about the size of the anal. 



Fin rays, D. XII, 11 or 12. A. II, 10. 



Color dark olive above, with blackish markings as usual in these fishes : 

 sides with vertical bars, somewhat diamond-shaped, but quite narrow, 

 acute above and acuminate below, more or less confluent along the 

 middle; about 12 in number; in color, dark greenish, varying to jet black 

 in accordance with the feelings of the fish. These bars are most distinct 

 near the middle of the body, and broadest behind. 



Inner half of each of the vertical fius, black, outer half more or less 

 speckled and barred : top of head black, a black band through eye and 

 snout, and a dark vertical shade below the eye; markings more or less 

 shown by all the Darters. A small black spot between two smaller ones 

 at base of caudal fin. 



Length four inches. 



Habitat. My specimens were taken in small tributaries of 

 the Etowah and Oostanaula Rivers, in clear, rapidly flowing 



* Prof. Ajrassiz's specific account is as follows : " From the neigborhood of Mobile, 

 Alabama. Discovered by Albert Stein, Esq. Brown above, lighter below, with trans- 

 verse black bands, wider in the middle than nearer to the back or belly."
