Body elongate, compressed. Mouth terminal, more or less oblique; 

 upper jaw not protractile. Vomerine teeth present; teeth in the jaws 

 strong, the outer series canine-like. Opercular spine well developed. 

 Gill-membranes broadly united. Scales rather large. Lateral line 

 incomplete; an enlarged, black humeral scale. First dorsal fin low, 

 considerably lower than the second dorsal, of 7 to 9 subequal spines, 

 which, in the males, end in little fleshy knobs; anal fin smaller than 

 the second dorsal, with 2 spines, the first of which is always the larger. 

 Vertebrra {E. Uneolatmn) 14 + 21; size small. Coloration dark. The 

 species are extremely quick in their movements, and their coloration, 

 although not gaudy, is very elegant. 



(The word Etheostoma is stated by Rafinesquo to mean '^various mouths," the species 

 known to him — i. c, Fercina cajprodcs, Diplesium hlennioides, and Etheostoma Jlabellare —
