Petromyscus Thomas 1926, Ann. Mag. Nat. Hist., ser. 9, 17: 179.

Type Species: Praomys collinus Thomas and Hinton 1925

Discussion: Most faunal lists, either with or without reservations, have recognized only two species (Ellerman et al., 1953; Meester et al., 1986; Misonne, 1974). We retain our earlier arrangement (Musser and Carleton, 1993), based on study of museum specimens and original descriptions, and continue to recognize four morphologically distinctive species, a conclusion also recorded by Skinner and Smithers (1990). Comprehensive systematic revision should be undertaken.
