_Notropis venustus_ hybridizes extensively with _N. lutrensis_ (Hubbs, Kuehne, and Ball, 1953:226-230; Hubbs and Strawn, 1956), and that combination occurs in streams near the locality where KU 3516 was taken. KU 3516 resembles _N. lutrensis_ × _N. v. venustus_ in many ways, but is more slender than the latter hybrid. The depth of head, body, and caudal peduncle are greater in _N. lutrensis_ than in _N. venustus_ (much greater than in _N. whipplei_); therefore, specimens of _N. lutrensis_ × _N. venustus_ are usually deeper than _N. venustus_, whereas KU 3516 is less deep. KU 3516 has a rather sharp snout and thin, straight lips that are strongly suggestive of _N. whipplei_, rather than _N. lutrensis_, in which the snout is rounded and the lips are more obliquely decurved. There is less pigment underlying the anterior lateral-line scales in KU 3516 than in _N. lutrensis_ × _N. venustus_, and melanophores on the scale-pockets of KU 3516 are arranged in narrower, more distinct submarginal bars than in _N. lutrensis_ × _N. venustus_. Because of the difference in pigmentation, the lateral scales of _N. whipplei_ (and of KU 3516) appear more narrowly diamond-shaped than the lateral scales of _N. lutrensis_ or _N. lutrensis_ × _N. venustus_. The lengths and heights of the scales are approximately the same in all three species. Winters Creek, where KU 3516 was taken, flowed approximately five cubic feet per second at the time our collection was made; a landowner on the stream stated that it had been dry, except for pools, in the previous two summers. The water was somewhat gray, but nearly clear. The habitat consisted mainly of short riffles, with average depth of four inches, and pools to depths of two feet. Twelve species of fish, including _N. whipplei_ but not _N. lutrensis_ or _N. venustus_, were found; other minnows were _Semotilus atromaculatus_, _N. chalybaeus_, _N. cornutus_, _N. umbratilis_, and _Campostoma anomalum_.
