Distribution: NW Nevada and NE California to Texas ( USA), south to Baja California Sur, N Sinaloa, and Mexican Plateau to San Luis Potosi ( Mexico).

Discussion: Revised by Lidicker (1960). Includes insularis Merriam , viewed as a separate species by Lidicker (1960; see also Huey, 1964, Hall, 1981, and Best and Thomas, 1991 a, Mammalian Species No. 374), but as a subspecies of merriami by Best and Janecek (1992), Williams et al. (1993), and Patton and Alvarez-Castañeda (2000). Also includes margaritae Merriam (see Lidicker, 1960; Williams et al., 1993; Patton and Alvarez-Castañeda, 1999), which has been considered by others to be a distinct species (Best, 1992, Mammalian Species No. 400; Hall, 1981; Huey, 1964). The inclusion of both insularis and margaritae within merriami is supported by mitochondrial DNA sequence data ( Riddle et al., 2000 b), although these same data may eventually result in separation of populations of merriami (including insularis and margaritae ) from the southern half of the Baja California Peninsula as a species separate from the remaining parts of the species’ range.
