lower canines and somewhat enlarged outer lo\\'er incisors make 

 the sympliysis of the mandible distinctly broader and longer (antero- 

 posteriorly) than in Bougeitu,^. The tip and trenchant hinder edge 

 of the lower canines has carved a deep vertical groove in the front 

 face of the crown of the npper canines. The heavy canines and 

 anteriorly protruding lower jaw render this portion of the skull and 

 dentition somewhat bulldog-like in appearance. The cheek-teeth 

 are relativeh" weak (longitudinal ridges unusually low), and, in 

 accordance with this, the coronoid process low and much sloping, 

 the deflection of the brain-case greater than in any species of 

 Eousettus, except the weak-toothed E. lanosus. — The separation of 

 the premaxillae might suggest aflinities with Eidolon, the somewhat 

 enlarged i., with Pleropus ; but in no other characters does Boneia 

 show any leanings whatever to these genera.
