tooth-rows of opposite sides in the upper jaw are almost parallel, 

 the inner margins of the posterior molars being as close together as 

 the first premolars (Plate XXIV. fig. 3). 



The skull is much narrowed between the postorbital fossse, where 

 its transverse diameter is less than at a point corresponding to the 

 first upper premolar ; the sagittal crest is much developed poste- 

 riorly, and the supraoccipital crest forms a prominent process pro- 

 jecting very considerably over the concave occipital bone ; the mas- 

 toid and paroccipital processes are much expanded, and the basi- 

 occipital between the auditory bullae ossese is wider than long and 

 slightly excavated ; the bony palate is abruptly narrowed behind the 

 last molar, and extends as far back as the middle of the zygomatic 

 arch ; the mesopterygoid fossa very narrow (Plate XXIV. fig. 3).

This species, believed by the older naturalists to be thoroughly 

 sanguivorous in its habits, and named accordingly by Geofixoy, has 

 been shown by the observations of modern travellers to be mainly 

 frugivorous, and is considered by the inhabitants of the countries in 

 which it is found perfectly harmless. 



The stomach forms a simple pouch as in the insectivorous Bats, 

 with the cardiac and pyloric orifices rather close together, the latter 

 opening wide ; the mucous membrane is thickened and arranged in 

 broad folds. In the stomach of one individual I found some vege- 

 table matter of rather firm consistence, apparently portion of the
