which is marked even upon the cranium, and the 

 nostrils are surrounded by a circle of projecting 

 lamina?. They have four incisors, without any in- 

 terval above, and six below. Their ears are large, 

 not joined, and their tail is comprised in the inter- 

 femoral membrane. These species belong to Africa. 

 Daubenton has described one of them fVesp. hispi- 

 dus, Linn.) Bearded Bat. M. GeofTroy has ound 

 others in Egypt*. 



The Rhynopomes (Geoffr.) 



Have aD indenture not so strongly marked, tt.e nos- 

 trils at the end of the muzzle, and a small lamina 

 above : their ears are joined, and their tail extends 

 considerably beyond the interfemoral membrane. 

 One species of this subgenus is known : it belongs to 

 Egypt, and chiefly inhabits the pyramids f. 



The Taphiens (Thaphozous, Geoffr.) 



Have also a small foss or indenture on the forehead ; 

 but the nostrils are devoid of the elevated laminae, 

 and they have but two incisors above and four 

 below. Their ears are separated, and their tail free 

 above the membrane. M. GeofTroy has discovered 

 a species in the catacombs of Egypt J.
