COMMENTS: Huckaby (1980) followed Lawlor (1965) in treating P. yucatanicus as monotypic; Hall (1981) accepted Osgood's (1909) subspecific arrangement. The notion (e.g., Lawlor, 1965; Hooper, 1968b) that P. yucatanicus is most closely related to P. mexicanus has not received support (Carleton, 1973; Huckaby, 1980). See Young and Jones (1983, Mammalian Species, 196). P. mexicanus species group.
