from canines by narrow spaces, their crowns bifid or notched, rather 

 distinctly marked off from shafts, sometimes by an evident con- 

 striction. Canines small and weak, not peculiar in form, without 

 secondary cusps or distinct ridges, the anterior surface without trace 

 of longitudinal furrows. Except that the mandibular canines are 

 smaller, they are almost identical in appearance with those of the 



upper jaw. No 

 small maxillary 

 premolar or molar 

 (pm 2 , m 2 ). The 

 remaining maxil- 

 lary teeth (pm s , 

 pm 4 , and m 1 ) are 

 essentially as in 

 Pteropus, except 

 that they are rela- 

 tively smaller, and 

 the cusps and 

 ridges, though 

 sharp and distinct, 

 are not as large. 

 Anterior premolar 

 separated from ca- 

 nine by a notice- 

 able diastema, and 

 from next premo- 

 lar by spaces rela- 

 tively wider than 

 in Pteropus. 

 Small lower pre- 

 molar • (pm 2 ) of 

 about the same 

 relative size as in 

 Pteropus (dis- 

 tinctly larger than 

 incisors) , but with 

 an outer cusp and 

 obliquely flattened 

 surface. Other mandibular teeth differing from those of Pteropus 

 about as in the case of the corresponding maxillary teeth, the small 

 molar (m 2 ) closely resembling m % of Pteropus. Skull (fig. 9) broad 

 and flattened, the depth of brain case usually little more than half 

 its width. Deflection of occipital region slight, the alveolar line con- 



aVery noticeable in an immature E. franqneti from Mount Coffee, Liberia
