front of them. First lower premolar little more than half the size of the second, 
clovse to the canine. In an adult female of this species from Suez the outer upper 
incisors are so small that they are scarcely visible even with the aid of a lens, and on 
the right side of the upper jaw the first premolar is absent.

This bat is generally found in the cracks and crevices of buildings, and Lataste ^ 
mentions that in a fort near Biskra (Algeria) and in old ruined tombs at Ourgla he 
generally found only a single individual in a hole. It also frequents the date-palm. 
I’arturition takes place in the month of May in Egypt, and two are born at a time. 
Whether it hibernates in Egypt is unknown. 
It is distributed over Europe, south of the Alps and Pyrenees ; over Northern and 
North-eastern Africa ; also over Southern Asia as far east as Kachar. 
The specimens from Ramleh and Cairo are russet-brown above, this colour in the 
bats from the former locality being very intense between the eyes and on the head 
generally, whereas in the specimens from the margin of the desert about Luxor and 
Khayzam the colour generally is much paler. 
On the other hand, the specimen from the Fayum has the muzzle, ears, and 
membranes almost black, but the limbs themselves brownish. In the russet-brown 
and paler specimens there are distinct indications of a white margin to the wing- 
membranes, whilst in the dark-coloured individuals this characteristic marking is
