Discussion: Revised by Grinnell (1922) and reviewed by Best (1991, Mammalian Species No. 381) and Williams et al. (1993). Considered closely related to merriami , but clearly distinct based on morphological (e.g., baculum, Best and Schnell, 1974), chromosomal ( Stock, 1974), and molecular ( Johnson and Selander, 1971; Patton et al., 1976) characters.
