486 phyllostomidj:. 



cusps directed forwards, downwards, and inwards, with chisel-shaped 

 imnotched cutting-edges, their inner margins close together ; outer 

 incisor on each side very small, not equalling the cingulum of the 

 inner incisor in vertical extent, and occupying the narrow space be- 

 tween the inner incisor and the canine ; lower incisors equal, sym- 

 metrical, chisel-shaped ; first upper premolar with an oblique cusp, 

 directed forwards and slightly inwards, touching the base of the 

 canine ; second upper premolar much larger, unicuspidate ; last upper 

 molar somewhat less than half the antepenultimate molar ; first lower 

 premolar triangular, nearly equalling the second in vertical extent, 

 and exceeding it and the canine in cross section at the base ; first 

 and second molars equal, last molar three fourths the antepenulti- 

 mate molar.

Hab. Brazilian Subregion ; Peru. Appears to be confined to the 

 forest-clad districts of these countries. Living in hoUow trees, and 

 between the large leaves of dii3ferent species of palms. 



Next to Vampyrus spectrum this is the largest species of Bat 

 inhabiting the Western Hemisphere, the length of the head and 

 body being nearly four inches, while the forearm measures three 

 and a quarter. 



The stomach is a simple pouch with rather thin walls, the mucous 

 membrane not thickened or arranged in folds as in Vainpyrus spec- 

 trwn. I found the stomach of a specimen dissected by me filled with 

 the comminuted remains of insects. 



This species, in common with Vampyrus spectrum, was long 

 believed to be sanguivorous in its habits, and the Prince of Neuwied 

 gives credit to the current accounts (op. cit.). It is very probable 

 that most of the larger species of insectivorous Bats (like Mega- 

 derma lyra) occasionally feed on the smaller Bats and other small 

 mammals.
