TYPE LOCALITY: Egypt, Bir Victoria .

DISTRIBUTION: N. Egypt, west of the Nile.

COMMENT: Petter, 1975, Part 6.3:8, included perpallidus in pyramidum, but Corbet, 1978:122, and Schlitter, 1976, Diss. Abstr. Int., 37(6), considered perpallidus a distinct species. May be conspecific with latastei; see Cockrum, 1977, Mammalia, 41:78. Karyotypically distinct from latastei in the sense of Cockrum, 1977 (DML); see Jordan, 1974, Mammalia, 38:62, and Lay et al., 1975, Z. Saugetierk., 40:141-150.
