Grammomys Thomas, 1915 . Ann. Mag. Nat. Hist., ser. 8,16:150.

TYPE SPECIES: Mus dolichurus Smuts, 1832 .

COMMENTS: A distinctive genus as asserted by Ellerman (1941) and other workers (e.g., Hutterer and Dieterlen, 1984; Rosevear, 1969), and unrelated to Thamnomys with which it has often been united as a subgenus (Allen, 1939; Hatt, 1940fe; Hollister, 1919; Misonne, 1974; Petter and Tranier, 1975). Partly reviewed by Petter and Tranier (1975) and Hutterer and Dieterlen (1984), who provided morphological, distributional, and chromosomal comparisons. Morphological and chromosomal similarities exist with Thallomys (Olert et al., 1978) .
