Physical description: This is a blotched-sided minnow with a bulbous snout, a nublike barbel and a small superlateral eye. The typical size is from 50-75 mm SL. The body form is moderate, and slightly compressed with the dorsal fin origin anterior to the pelvic fin origin. The head length is moderate, the snout somewhat short and broadly rounded. The eye is supralateral and the mouth is moderate in size, inferior and horizontal. The frenum is absent. The lips are moderately thick and the medial portion is expanded anteriad. The barbel is abscent or a nubbin on the posterior end of the lip. The underside of the head is densely covered with moderate sized taste buds, and rarely there is 1-2 papillate buds present at the isthmus. There are 4-4 pharngeal teeth and the lateral line is complete with (3)39-42(45) scales. There are (26)28-30(33) circumbody scales, (13)15-16(17) circumpeduncle scales and (14)16-18(19) predorsal scale rows. There are 8 rays, 19 pricipal caudal rays (6)7 anal rays(5)7-8(9) pelvic rays and (13)15-17 pectoral rays. The breast is naked or almost naked *4205*. Reproduction: This species spawns in the late spring to early summer. In Tennessee, females were gravid on the 14th of April and in Virginia, from 14-21 May. Some Tennessee females had eggs freely flowing on 12 June in 25 degree C water while others were noted in 15 degree C water on the 28th and 29th of May. During spawning the female reested in depressions between or behind rocks and the male approached from the side or downstream and contacted the female cheek to cheek and vent to vent. They spawned by quivering and then the male left *4205*. Behavior: The young occupy shallow areas with little or no current and then move into the adult habitat later in the summer. This species gleans a variety of immature insects including midge and blackfly larvae and also other invertebrates and large amounts of microscopic plants and detritus. They sometimes search along plant stems for food *4205*. Population parameters: This species usually reaches maturity by age one, and always by age two *4205*.
