Myomys daltoni (Thomas, 1892) . Ann. Mag. Nat. Hist., ser. 6, 10:181.

TYPE LOCALITY: West Africa (see discussion in Rosevear, 1969:412) .

DISTRIBUTION: From Gambia and Senegal through Sierra Leone, N Ivory Coast, S Mali, Burkina Faso, Ghana, Togo, Benin, Nigeria, S Chad and Central African Republic to SW Sudan; eastern limits unresolved.

SYNONYMS: butleri, ingoldbyi, saturatus ( Ingoldby, 1929, not Lyon, 1911), tuareg.

COMMENTS: Reviewed by Rosevear (1969) and Van der Straeten and Verheyen (19786). Although its range is allopatrically complementary to the distribution of M. fumatus , M. daltoni is probably not conspecific with that E African species. Chromosomal morphology is presented by Matthey (1964). The name tuareg was described as a subspecies of Grammomys macmillani , but listed by Rosevear (1969) as a species of Grammomys of doubtful validity, and finally identified by Braestrup and Hutterer (1985) as a possibly distinct subspecies of M. daltoni. Setzer (1956) retained butleri, known only by the holotype collected in SW Sudan, as a species, but its morphological traits, judged by Setzer's description, are those of M. daltoni.
