Praomys jacksoni (de Winton, 1897) . Ann. Mag. Nat. Hist., ser. 6, 20:318.

TYPE LOCALITY: Uganda, Entebbe .

DISTRIBUTION: From C Nigeria through Cameroon and Central African Republic to S Sudan, Zaire, N Angola, Uganda, Rwanda, Kenya, and southward through E Tanzania to N and E Zambia.

SYNONYMS: montis, peromyscus, sudanensis, viator .

COMMENTS: At one time listed as a subspecies of P. tullbergi (e.g., Hollister, 1919), jacksoni is a distinct species (Allen, 1939; Ansell, 1978; Van der Straeten and Dieterlen, 1987; Van der Straeten and Dudu, 1990) occurring sympatrically with P. tullbergi . The problem of identifying the holotype of jacksoni as well as current names associated with the species was reviewed and discussed by Van der Straeten and Dieterlen (1987) and Van der Straeten and Dudu (1990). The latter authors recognized montis and peromyscus as species; the P. jacksoni complex is probably composite, but until the forms representing potential species ( viator, montis, peromyscus) have been diagnosed and their geographic ranges described we include them here under P. jacksoni . Van der Straeten and Dieterlen (1992) reported results from craniometrical camparisons among four samples of P. jacksoni collected at differnent altitudes (850-3300 m).
