There is a large dark blotch at the base of the dorsal fin base. The dorsal, anal, adipose, and caudal fins are edged in black. The anal fin is short, with 21-24 rays. The first gill arch has 11-13 rakers. To 11 1/4 in. (29 cm) total length.
The Flat Bullhead is found in streams on the Atlantic Piedmont and Coastal Plain from the Roanoke River in Virginia to the Altamaha River drainage in Georgia. The species is generally uncommon.
