THE MAMMALS OF EGYPT. 
PTEROPODID^. 
This family is composed of two subdivisions, viz. the Pteropodince, having wel]- 
developed molars and a moderate-sized tongue; and the Megaloglossince, with molars 
hardly raised above tbe gums and an immensely elongated tongue. The first of these 
subfamilies is represented on the African continent by three genera— Epomopltoriis, 
llousettus, and Scotonycteris; while one genus {Megaloglossiis) of the second subfamily 
occurs in West Africa only.

separated by a deep groove which is prolonged backwards and upwards from the upper 
lip; chin slightly grooved ; ear with a distinct lobe. First digit of manus elongate; 
second clawed; third metacarpal as long as, or longer than, the second digit. Wings 
extending from the sides of the back and joined to the hind leg as far as the base of 
tbe second metatarsal. Interfemoral membrane traversed about its middle by a strong 
tendinous band extending from the heel to the side of the tail. Tail very short, its 
proximal half attached to the under side of the interfemoral membrane, but not

The longitudinal furrow which traverses the molars completely disappears in fully 
grown animals, the crowns of these teeth becoming flat. 
Distributed over Africa; extending into Southern Asia eastwards as far as the 
Malay Archipelago.
