Grammomys dryas (Thomas, 1907) . Ann. Mag. Nat. Hist., ser. 7, 19:123.

TYPE LOCALITY: " Kenya Colony" (Uganda), Ruwenzori East, 6-7000 ft .

DISTRIBUTION: A montane Western Rift endemic: Ruwenzoris and Kivu region in Uganda and Zaire, NW Burundi (specimens in the Field Museum of Natural History).

COMMENTS: Originally described as a species of Thamnomys by Thomas (1907a) and listed that way by Allen (1939). Ellerman (1941), however, treated it as valid species of Grammomys, which, in the absence of a critical systematic revision of the genus, best expresses current knowledge. Thomas (1907a) noted the diagnostic mammary count in dryas, which, in combination with cranial traits, set it apart from other described forms.
