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 ars 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.
