species of Chiroptera; the Horseshoe-Bats of Europe (Rhino- 

 lophus ferrum-equinum and hipposideros) ; the Long-eared Bat 

 (Plecotus auritus], whose ear is nearly as long as its body; the 

 Noctule (Vesperugo noctula), 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.
