Discussion: Reviewed by O'Farrell and Blaustein (1974 a, Mammalian Species No. 46). Hafner et al. (1979) discounted the suggestion by Hall (1941:380-382) of hybridization between megacephalus and pallidus . Also, Hall's suggestion (1981:560) that leucotis may warrant specific status is not supported (see Hafner and Hafner, 1983). Subspecies listed by Williams et al. (1993).
