COMMENTS: Conspecificity of Old and New World populations advanced by Rausch (1953) and corroborated by subsequent studies (e.g., Nadler et al., 1976, 1978; Rausch and Rausch, 1975a). European populations reviewed by Henttonen and Peiponen (1982). Variation in pattern of third upper molar and its systematic implications reported by Nakatsu (1982) for Japanese populations. North American populations revised, as C. dawsoni , by Orr (1945), and, as C. rutilus by Manning (1956). Also see account of C. gapperi .
