LEAF-NOSED BATS. 263 



The Horseshoe axd Leaf-Xosed Bats. 



Family Rhinolophid^. 



The bat represented in the accompanying illustration is one of the two British 

 representatives of a well-marked and rather numerous family distributed over the 

 greater part of the Old World. This family is technically known as the likino-

The horseshoe-bats {Rhinolopkus), of which our figure is an example, always 

 have 32 teeth, of whicii the incisors number 1, and the cheek-teeth 5. on 

 either side: and they are further distinguished by the shape of the nose- 

 leaf, which consists of two portions, the one immediately over the nose being 

 horseshoe-shaped, and the posterior one pointed. Moreover, the ears have a large 

 process of membrane in front, termed the antltnujius.
