Otomys dollmani Heller 1912

Otomys dollmani Heller 1912, Smithson. Misc. Coll., 59: 5.

Type Locality: Kenya, Matthews Range, Mount Gargues (Urguess), 7000 ft.

Vernacular Names: Dollman's Vlei Rat.

Distribution: Known only from the type locality.

Discussion: Described as a subspecies of orestes and afterwards swept under either O. irroratus (Bohmann, 1952; Petter, 1982) or O. tropicalis (Misonne, 1974; Musser and Carleton, 1993). Hollister (1919) noted dollmani ’s differentiation from both orestes and tropicalis on Mount Kenya (notably its smaller size, lack of postauricular patches, six-laminated M3, flatter skull profile, as verified with USNM type series) and long ago elevated it to species. We agree.
