Fins moderate; dorsal much smaller than anal. Outer series of teeth some- what enlarged. Coloration pale olive, bluish in life; a V( ^y distinct brownish line along the edges of each row of scales, appearing wavy or serrated as it follows the scales; about 10 of these longitudinal stripes are present; males with the lines interrupted, appearing a>^ series of dots and further marked by about 9 dark cross-bars; adults with a dark blotch below the eye, sometimes confluent with it. Oviduct free from anal. Head 32; depth 3J. D. 7; A. 9; scales 35-10. L. 2^ inches. Lake? and sluggish streams from Ohio to Iowa. (Agassiz, Amer. Jour. Sci. Arts, 1854, 353; Jordan, Proc. Acad. Nat.

Head wide, with overhanging supercilia; iuterorbital width twice the diameter of the orbit, which enters the length of the head 2J times. Color uniform olivaceous, the scales with brown edges; cheeks silvery; no spots on the head. Body stout. Head 4J, D. 7; A. 8. Scales 30-lf. Lenj^h ; {GopCj MSS.)
