Identification: Scott and Crossman (1973); Becker (1983); Page and Burr (1991). Gilbert (1998) recognized three distinct subspecies: C. p. plumbeus, C. p. greeni, and one formerly known as C. p. dissimilis (a name no longer available).

Nonindigenous Occurrences: Introduced into the Niobrara River in Nebraska (S. Schainost, pers. comm.). This species is known from the Big and Little Sandy creeks, Green River drainage (Colorado River basin), and Yellowstone Lake, upper Colorado drainage, and Yellowstone National Park, Wyoming (Baxter and Simon 1970; C. Wheeler, personal communication; Lee et al. et seq 1980; Hubert 1994; Tilmant 1999).

Means of Introduction: Probably introduced by bait bucket release (Baxter and Simon 1970).

Status: Established in the Green River drainage and in Yellowstone Lake, Wyoming (Baxter and Simon 1970).

Impact of Introduction: Unknown.

Remarks: Wydoski and Whitney (1979) stated the species is not native to Idaho and that it has been introduced into the panhandle region, however, Simpson and Wallace (1978), Lee et al. (1980 et seq.), and Page and Burr (1991) depicted the species' range to include northern Idaho and made no mention of it being introduced there. We believe it is probably native to the Kootenai drainage in northern Idaho. According to C. Gilbert (personal communication), its occurrence in the upper Colorado basin may have involved an introduction; however, he also noted that the species may have entered the Colorado basin by way of a localized stream capture involving a tributary of the Colorado and the upper Platte River. Gilbert (1998) discussed the distribution of this species in his account of Ceratichthys squamilentus.

Voucher specimens: Wyoming (currently in C. Wheeler's possession but will be placed in the UWL museum).
