of the Ohio, from the falls to the mouth, and it runs up the small 

 creeks, but is rare every where. lis length is from six to twelve 

 inches. The snout is rounded, the head sloping and small, the 

 preopercule rounded, the opercule flexuose or nearly lobate; 

 the eyes are black and beyond the mouth. The back is almost 

 black, the two dorsal fins are dotted like the body, the first has 

 about twelve spiny rays, and the second about eight soft rays? 

 this last is very near the tail. The anal fin has about twenty 

 rays and begins just below the vent and the end of the first dor-

 II Genus. Bubbler. Amblodon. Amblodon. 



Body elliptical, compressed, scaly; head and giii covers sca- 

 ly, jaws with small fily teeth, throat with a triangular bone be- 

 neath, covered \uth large round hollow and obtuse teeth. Gill 

 cover with two pieces, preopercule slightly denticulate at the 

 base, opercule without teeth nor spines: branchial membrane 

 vith six rays. Two dorsal fins contigous, the first spiny, the 

 second partly so, scaly along the base. Vent posterior. 



This genus was called by me Afilodinotus G. 8. of my Me- 

 moir on 70 New Genera of American animals, in the journal of

 base of second dorsal fin, besides the singular teeth. Only one 

 species is knovrn as yet.
