Discussion: Distinguishing Z. hudsonius from Z. princeps using repeated cranial measurements elaborated by Conner and Shenk (2003). The S Rocky Mtn population originally described as luteus , formerly assigned to princeps , was shown to represent hudsonius by Hafner et al. (1981). Diagnosis, records and range map (excluding Mississippi), provided by Hall (1981). Mississippi record given by Kennedy et al. (1982). Results of new survey for the species in New Mexico reported by Morrison (1992), and population in NE Oklahoma reviewed by Kasper et al. (1993). Reviewed by Whitaker (1972, Mammalian Species, 11; 1999 b), and Whitaker and Hamilton (1998). For synonyms see Hall (1981).
