The Bats of the next family gained their trivial name not so much 
for any especially bad habits the majority may have possessed, but 
on account of the blood-sucking propensities of the Desmodontine 
section. Indeed, some of the species are far removed from the ranks 
of the Vampires and are insect-eaters, while a large number live on 
both insects and fruit. The species of the various genera differ 
widely in their appearance, some of them with their large ears and 
exaggerated cutaneous appendages presenting very extraordinary 
visages. The color of their fur is dull in hue, and some species are 
marked with white streaks. The blood-sucking members are modified 
in body and teeth to adapt them more perfectly for their nefarious 
practices. The Vampire group in this volume ends with the genus 
Hemiderma.
