PHTLLOSIOMID^E. 



As in many other species of Bats, the peculiar mobility of the 

 ears has been noticed in A. perspieillatus. Mr. Osburn remarks of 

 a specimen which he was endeavouring to recapture : — " As I 

 cautiously advanced the net, he showed his sense of danger by 

 elevating the head a little, whilst the little round ears underwent a 

 constant and very rapid motion as if vibrating, and, what made it 

 more curious, each independently of the other. It had a very curious 

 effect, like a person rolling his eyes different ways. The nose-leaf 

 had also a motion, but slighter. It looked as if he were feeling for 

 sound and smeU, to ascertain the nature of the attack."
