HISTORY OF QUADRUPEDS. 515 



THE LONG-EARED BAT. 

 (Vespcrtilio Ann'tns, Linn. L'Oreillar, Buff,) 



Is only an inch and three quarters in length; the 

 extent of its wings is seven inches ; its ears are 

 above an inch long, very thin, and almost trans- 

 parent ; within each of them there is a membrane, 

 resembling an ear, which 4 may possibly serve as a 

 valve to defend the organs of hearing during its 

 inactive state. 



THE (TREAT BAT. 



(La Nodule, Buff.) 



Is found in Great Britain, but is not so common 

 as the two last-mentioned : It is likewise found in 

 France, and is common in various parts of Russia. 



Its length is nearly three inches ; that of the tail 

 one and seven-tenths ; the extent of the wings thir- 

 teen inches ; the ears are short, the hair of a reddish 

 ash colour, and on the chin there is a very small 

 wart.
