THE MAMMALS OF EGYPT. 
lateral glandular eminences well developed. Nostrils crescentic, opening anteriorly, 
and separated by a nearly flat interval equalling the vertical depth of the front of the 
muzzle between the nostrils. Ears slightly shorter than the head; the internal border 
somewhat emarginate below the rounded tip, then convex and slightly concave, followed 
by a marked anterior convexity sweeping backwards to the attachment of the conch. 
External border of ear slightly concave in its upper half, and markedly convex as it 
bends downwards and forwards to its point of attachment over the angle of the jaw in 
a straight line below the attachment of the internal border, and considerably behind a 
vertical line drawn through the outer canthus of the eye; before its attachment is a 
large well-marked lobe. The tragus is slightly bent forward, somewhat falciform, and is 
broadest immediately above its base ; it has a well-marked anteriorly curved small lobe 
at its base. Thumb with a small callosity at its base, and another at the base of the 
metatarsus. Wing-membrane arising from the side of the metatarsus at the base of 
the proximal phalanx. Postcalcaneal lobe feeble. Last vertebra of tail and sometimes 
half of the penultimate vertebra free, in the latter case the free portion nearly equals 
the length of the thumb. 
Sides of the head from the ear to the tip of the muzzle nearly nude,, but the upper- 
surface, from a little way before the ears, covered with fur. Inner surface of the conch 
with straggling white hairs, most numerous towards the internal border; upper half 
qf back of ears nude. Wing-membrane on its under surface close to the bcjdy, from 
behind the humerus to the femur, clad with fur, but not very thickly; a few straggling 
hairs occur here and there on the under surface of the wing, and similar hairs on the 
under surface of the iuterfemoral membrane. 
Buff colour above, nearly pure white on the under surface; wing-membranes and ears 
reddish brown. 
Inner upper incisor strongly bicuspidate somewhat antero-posteriorly, and more or 
less grooved to the cingulum ; outer incisor small, opposed to the side of the posterior 
cusp of the inner. Upper premolar large, somewhat longer than the molars, closely 
opposed to the canine. Last molar narrow antero-posteriorly, almost lamellar. Lower 
incisors markedly trifid, more or less overlapping. First lower premolar rather less 
than half the height of the second, and placed in the tooth-row. 
Nothing is known regarding the habits of this species. The types were obtained in 
Cairo, and were named in honour of the collector. Dr. Walter Innes; and since then 
another example has been procured by Dr. Noack from Egypt, but from what part of 
the country has not been stated. 
As pointed out by Lataste in the original description, this species is closely allied 
to V. serotmus, but the differences enumerated by him as existing between the two 
forms seem sufficient to entitle both to specific rank until the range of variation among 
the members of this genus is better understood.
