Head comparatively elongate, bluutish, rather broad and flattened 

 above, -1 "> in length. Body stoutish, varying to moderately elongate. 

 Lips rather lull, theblimtisli muzzle projecting beyond the large mouth ; 

 greatest depth of cheeks more than half distance from snout to pre- 

 operde. K \ e rather large. Dorsal fin medium, its developed rays li ( - 

 14, usually l.'j in number, its free edge nearly straight, its longest ray 

 shorter than head. Scales large, about 4.~> in the lateral line. Oliva- 

 c.-niis ; sides silvery ; lower fins in the adult red or orange. Great Lakes 

 to Virginia, southwest \vard to Arizona ; one of the most abundant 

 fishes, reaching a length of 2 feet or more. The Red Horse of the Ohio 

 and Mississippi, with the head relatively longer and the mouth larger, 

 is perhaps worthy of distinction as var. duqiicsni (Le Sueur) Jor. The 

 eastern form (var. macrolepidotum] is scarcely distinguishable from the 

 next species.
