BRITISH BATS. 43 



of vertebrae is as follows : cervical, 7 ; dorsal, 11 ; 

 lumbar, 7 ; sacral, 4 ; and caudal, 1 0. There are 

 four incisors in the upper jaw, the two middle ones 

 slightly separated, two canines, and five molars ; 

 the first, small and conical, the second, larger with 

 a conical point, and the last three nearly equal, with 

 several small points. In the lower jaw the incisors 

 are six, the canines two, with an internal acute 

 process, the anterior conical molars, and three 

 posterior molars, each with three points. The jaws 

 are incapable of being moved laterally, and the bat 

 feeds by a succession of pecking bites, just as a cat 

 does when engaged with a tough piece of meat. 

 The voice of the long-eared bat consists of a 

 chirping kind of squeak, not so shrill as the cry of 

 most of its congeners, and resembling the voice of 

 the shrew (Sorex tetragonurus) so frequently heard 

 in hedgerows and banks during the summer. The 

 dimensions of these bats are as follows :
