A few denticulations, more or less obvious, on the borders of the preopercle. Palatines and 
tongue smooth, and without teeth. Minute teeth on the jaws, vomer and pharyngeals. 
Branchial rays six. Opercle with an elongated membrane at its angle. 
Oxs. This is an exclusively American genus, and composed entirely of fresh-water fishes. 
It is very closely allied to the succeeding genus. The type of this genus was originally made 
a Labrus by Linneus, Lacepede and others; but in calling it a Perch, the common people, 
according to Cuvier, exercised more discernment than naturalists.
