fin. Vent posterior. Pectoral and abdominal fins oboval. Eyes large. Length three 

 inches ; good bait for Perch, Bass, Red-eyes or Ring-eyes, etc." Raf., 1820, Icbth. 

 Ohio, 86. 



A small obtuse head with a silver spot on the top (but not always be- 

 tween the eyes), dorsal opposed to anal, oboval entire tail, jaws nearly equal, 

 small mouth (but not without lips), posterior dorsal fin, pectoral and abdomi- 

 nal fins oboval, vent posterior, and eyes large (especially in young) may 

 refer to either of several species in the Cumberland; while in that described 

 here as olivaceous of Storer, the silver spot is usually on the occiput when 

 present, the mouth is large and has lips, and broad lateral bands are so con- 

 spicuous that one can hardly believe Rafinesque would describe a fish possess- 

 ing them as merely " brownish, pale beneath."
