THE MAMMALS OE EaTPT. 
The forehead is convex. The ears are large, broad, and placed relatively closer to the 
eye than in the other Egyptian species ; when laid forwards they reach to the middle of 
the moustachial area, and to the upper margin of the opposite eye when laid across the 
head, whereas in the other species they fall far short of that distance, just crossing the 
mesial line of the head. The anterior margin in its upper half is nearly straight, but 
directed obliquely backwards, while in the small species it is rounded. The anterior 
border of the ear nearly up to the rounded summit is fringed with rather long, dark brown 
hairs, curving inwards to the conch-cavity, the summit and rounded posterior border 
of the ear being fringed with minute hairs increasing in length towards the orifice of 
the conch, where they become long and silky, but erect. The inner surface of the ear 
is covered with fine, white, adpressed, silky hair, but not sufiiciently dense to obscure 
the skin, and the outer surface is covered in a similar manner, but with yellowish hair, 
which is much more dense along a narrow band close to the anterior border. The skin 
of the ear on both surfaces, in its upper two-thirds, is clearly marked off by its colour 
ifom the lower third, which is white; the upper two-thirds are black behind, but of a 
leaden colour in front. The thumb is small, but with a well-developed flat claw. The 
third finger is very slightly longer than the fourth, and the second than the fifth. The 
claws are rather long, curved, and sharp. Posterior to the thumb there is a very large 
tubercle, with a smaller one external and slightly anterior to it, the palm immediately 
in front being swollen, but concave further in advance. Behind these tubercles there 
are short white hairs partially curving over them. The palm itself is perfectly nude, 
but the dorsum of the hand and the sides of the fingers are more or less covered with 
downwardly curved white hairs. The toes of the hind foot are more or less laterally 
compressed. The middle toe is the longest, with a feeble claw; the inner toe is 
somewhat longer than the outer; the claws on both are short and stout, flat internally 
and convex externally. The sides of the toes, up to the distal end of the common 
metatarsal, but more especially their under surfaces, with the exception of the fronts 
of the subungual pads, are clad with strong, brush-like hairs, directed obliquely 
forwards, and curving inwards on the sole of the foot to the mesial line, where 
a prominent ridge is formed. The hairs from the sides of the toes and cushions 
are white; those on the under surface of the phalanges dark brown. The upper 
surface of the foot from the heel downwards is covered, but not very thickly, 
with short white hairs. The under surface of the tarsus in the mesial line is 
semi-nude, but is more or less obscured by the hairs from its sides, w'hich curve 
inwards and forwards. Immediately behind the base of the middle toe there is 
a small bare area on the sole hidden by the inwardly curving hairs of the foot- 
brushes, at the back part of which there is a somewhat sharply pointed, rather 
prominent tubercle. The lower third of the tibial portion of the leg is sparsely 
clad with reddish-yellow hairs. The tail is more or less quadrangular in transverse
