1 6 BAT-TRIBE. 



proportions, the first being much smaller, the second some- 

 what larger. 



In regard to these teeth, the jaw in question resembles 

 that of the Molossi, especially MoL Daubentoni, but it 

 differs from all the species of that genus that I have seen 

 in the more produced angle of the jaw. In this character, 

 as well as in the number, shape, and size of the teeth, it 

 agrees closely with the Rhinolophi, especially the species 

 called " Greater Horse-shoe Bat. 11 It is too large for any of 

 our native species of Vespertilio, save the Noctule, to which 

 the proportions of the premolar forbid a reference : but it 

 corresponds in the size as well as shape of the bone, and 

 in the modifications of the teeth, with the RMnolophus 

 Ferrum-equinum. 



Unequivocal remains of this species of Bat, from the 

 bone-cave called Kent's Hole near Torquay, Devon, are con- 

 tained in the British Museum : some of the specimens appear 

 to be in the same absorbent condition, as the bones of the 

 ffytena, Rhinoceros, &c., from the same cave ; others are 

 evidently more recent. It is worthy of remark that the 

 Greater Horse-shoe Bat is most commonly met with in the 

 Devonshire caves at the present day, and is the only species 

 known to frequent Kent's Hole.* 



In every other example of remains of bats from bone- 

 caves, where the condition of the specimen has permitted 

 a direct or approximate identification, it has been with 

 some existing British species ; and the general result of this 

 part of my palseontological researches the most tedious, 

 but yielding the least important results is, that no remains 

 of Bats have hitherto been found, however situated in 

 caverns, or altered in chemical constitution, which establish 

 the former existence of any species not now known to exist,
