The adults are distinguished by their decided pale brown colour, more or less 
speckled, owing to the black tips and yellowish-brown subterminal bands to thn 
hairs. On the sides the colour passes into rather rich fawn, clearly defined from the 
pale yellowish white of the under parts. Prom the moustachial area to the shoulder 
the line of junction of the colour of the sides of the head has a decided yellowish- 
rufous tint. The skin of the conch is dusky leaden and the exterior half and the upper- 
third of its inner surface are covered with pale brown hairs, the remainder being 
perfectly nude. The back of the conch is sparsely covered with short pale brown hairs. 
The anterior margin of the conch has a rather strong fringe of longish hairs. The 
margins of the eyelids are black and the feet are white. The tail is brown above, 
yellowish below, and is covered with fine stiff short pale brown hairs, which do not 
conceal the rings. 
A male and female with their litter of six young ones, with eyes and ears still closed, 
were obtained in a Bishareen hut on the desert outside Assuan; two other specimens 
were taken in the same locality.
