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 3 , 
pm 4 , and m 1 ) are 
essentially as in 
P ter opus, 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 P t er o p u s . 
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 3 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-
