LEAF-NOSED BATS. 263 
The Horseshoe and Leaf-Nosed Bats. 
Family Rill NO L ophiDjE. 
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 Rhino- 
lophidce, and includes the horseshoe-bats ( Rhinolophus ) and the leaf-nosed bats 
( Hipposiderus ), together with some less important genera. All of them are 
characterised by having a well-developed nose-leaf completely surrounding the 
nostrils, which are situated in a depression of the snout. And they are also distin¬ 
guished by their large ears, which have no trace of an inner ear, or tragus, and are 
in most cases completely separate from one another at their origin at the head. 
The horseshoe-bats (Rhinoloph us), of which our figure is an example, always 
have 82 teeth, of which the incisors number h, and the cheek-teeth ^ 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 antitragus.
