BATS. LEMURS 
29 
species of Chiroptera; the Horseshoe-Bats of Europe {Rhino- 
lophus ferrum-equinum and Mpposideros ) ; the Long-eared Bat 
{Flecotus auritus), whose ear is nearly as long as its body; the 
Noctule ( Vesperugo nctctula), the largest of our English Bats ; the 
peculiar-looking Cheiromeles torquatus of the East Indies; the 
White Bat [Diclidurus albus) of South America^ one of the very 
few Mammals, and the only Bat, normally white in colour; the 
Vampire {Vampyrus spectrum), the largest of the American Bats, 
formerly erroneously supposed to be guilty of blood-sucking ; and, 
finally, the real blood-sucking Bat [Desmodus rufus), of which 
the specimen exhibited was caught by Mr. Darwin in the act of 
sucking blood from a horse. These Bats attack men as well as 
animals in their sleep, fanning the victims with their wings. The 
wounds they inflict are small, but often continue to bleed after the 
Bats are satisfied, and do not readily heal.
