Genus VAMPYRUS Leach 



Very large general size, the forearm over 100 millimeters or 

 four and one-fourth inches long and wing expanse about 760 milli- 

 meters or two and one-half feet, alone distinguishes the genus 

 Vampyrus among American bats. The ears are long, relatively 

 narrow and round-pointed, and the interfemoral membrane is large, 

 but there is no external tail. In the form of the braincase the skull 

 closely resembles that of Phyllostomus, but the sagittal crest is much 

 higher and projects farther posteriorly ; the rostrum and mandible 

 are much longer; the latter affording space for an additional pre- 

 molar; the nasal opening is slightly extended backward by a V- 

 shaped emargination. Dental peculiarities are numerous, including 

 the deep emargination of the lateral borders of the first and second 

 upper molars, owing to displacement inward or greatly reduced size 

 of mesostyle. The teeth are 34 in number.
