THE MAMMALS OE EGYPT. 
Gulf, also in alcohol, show two pairs of pectoral nipples, one placed a short distance 
above the other, a unique condition in the order Chiroptera, or, indeed, in any of the 
higher Mammalia, but whether both pairs have functionally active milk-ducts has to be 
ascertained.

3 ? from the Oasis of Siwah. 
Snout not abruptly truncated in front, muzzle with a mesial depression, a furrow 
above the upper lip. Inner margin of nostrils slightly swollen and projected forwards 
beyond the outer margins, separated by a shallow mesial furrow. Grooves on the 
upper surface of the muzzle feebly indicated. Ears rounded at the tips, slightly if at 
all emarginate below the tip on the external border, which is moderately convex 
as it approaches the head. Tragus when laid forwards reaching the nostril. Upper 
surface very pale brownish above ; under parts white. 
Nothing is known regarding the habits of this bat. The male and female obtained 
by Lataste at Ourgla, in the Algerian Sahara, were caught in a house in which he 
was sleeping. They entered his chamber, in which a candle was burning, through 
the open door. The first suspended itself to the ceiling, and while it was being 
caught the second entered. 
This bat has been recorded from the Western Himalayas (Gilgit, 5000 ft.), 
Libyan Desert (west of Alexandria and Oasis of Siwah), Lower Nubia (Wadi Haifa), 
and Algerian Sahara (Ourgla). 
The specimens of this bat obtained by me from the Oasis of Siwah, all females, 
were originally preserved in alcohol, but in the transit across the desert the alcohol 
evaporated, and the specimens were more or less dried up. The desiccating action 
much contracted the front of the muzzle, at least I suppose so, because a male of this 
species from Ourgla preserved in excellent condition in alcohol, and for permission to 
examine which I am indebted to M. Lataste, presents a muzzle with the nostrils well 
apart and consequently not nearly so pointed as in the Siwah specimens. I have accepted 
this Ourgla individual as yielding the essential features of the muzzle of 0. hempricU, 
Peters.
