TYPE LOCALITY: Sudan, W. Kordofan, Agageh Wells .

DISTRIBUTION: N. Nigeria, Mali, and Niger to Chad, Sudan, and Kenya.

COMMENT: Includes cosensi, nigeriae, and sudanensis; see Kock, 1978, Senckenberg. Biol., 58: 127, who also included rosalinda in this species; but see Petter, 1975, Part 6.3:9, Schlitter, 1976, Diss. Abstr. Int., 37(6), and Corbet and Hill, 1980:164, who considered rosalinda a distinct species. Petter, 1975, Part 6.3:9, considered cosensi as possibly distinct and included dalloni in agag, but Kock, 1978, Senckenberg. Biol., 58: 126, included dalloni in gerbillus . DLH and DML followed Schlitter, 1976, who considered nigeriae a distinct species, as did Tranier, 1975, Mammalia, 39:703-704; DML also considers cosensi distinct pending revision.
