Deacription. — Body elongate, compressed, the back scarcely arched; head long and 

 rather pointed, entirely destitute of scales; mouth rather large, terminal, oblique, the 

 lower jaw notably the longer; eye moderate, longer than the snout, about 4 in head; 

 opercular spine strong ; fins all low, the first dorsal in the males about half as high as 

 the second, higher in the females; caudal large, rounded ; anal spines loager in females 



*The word Etheoatoma is stated by Rafinesque to mean "varioua moutha," the species 

 known to him, i. e., Percina oaprodes, Dipleaium blennioidea, and Etheoatoma flabellare — 

 being so different in respect to the form of the mouth, that he conceived that they 

 siight belong to different subgenera.
