SPECIES Spermophilus (Spermophilus) canus

Author:Merriam, 1898.
Citation:Proc. Biol. Soc. Wash., 12: 70.
Common Name:Merriam's Ground Squirrel
Type Locality:"Antelope, Wasco County, Oregon." [USA].
Distribution:USA: E Oregon, except NE and SE corners; extreme NW Nevada; W side of Snake River in WC Idaho.
Status:IUCN Lower Risk (lc).
Comments:Subgenus Spermophilus (Hall, 1981:383). Includes vigilis (see Vorontsov and Lyapunova, 1970; Nadler et al., 1984, wherein that junior synonym was employed as the species name). Formerly considered a subspecies of townsendii (Hall, 1981:383-384), but differs in diploid chromosome number (Nadler et al., 1984). No hybridization between canus (2n=46) and adjacent mollis (2n=38) or townsendii (2n=36) has been reported (Rickart et al., 1985). Reviewed (in part) by Rickart (1987), as S. townsendii.
