Discussion: P. crinitus species group. Revised by Osgood (1909); subspecific taxonomy updated by Hall and Hoffmeister (1942). Initially placed in subgenus Haplomylomys (Osgood, 1909); later transferred to subgenus Peromyscus (Hooper and Musser, 1964 b) . Karyotype viewed as primitive for the genus (Greenbaum and Baker, 1978; Stangl and Baker, 1984 b). Population on Isla San Luís Gonzaga ( pallidissimus), N Sea of Cortez, genetically similar to mainland P. crinitus and retained as subspecies (Hafner et al., 2001). A composite of at least two species, the status of long-tailed forms (e.g., disparilis and delgadilli) in particular meriting reassessment. See Johnson and Armstrong (1987, Mammalian Species, 287).
