and well developed, without secondary cusps or prominent cingula, 
the maxillary canines with deep longitudinal groove on anterior sur- 
face. Cheek teeth small, without distinct contrasts of size or form, 
the two anterior in each jaw (pm 2 , pm s , pm 2 , pm 3 ) with the crowns 
compressed and elevated into distinct though blunt cusp, the others 
(pm

m 2 , m 3 ) with narrow nearly flat crowns 
bounded by indistinct ridges, of which that on the outer side is the 
less developed. Anterior premolar, both above and below, close to 
canine, but separated from succeeding 
premolar by space about double as 
great as width of its crown. In both 
jaws the anterior premolar is smaller 
than the next. Skull (fig. 10) with a 
weak rostrum and large brain case, the 
occipital region not tubular but so 
strongly deflected that the alveolar line 
projected backward passes between root 
of zygoma and middle of braincase. 
Postorbital processes short and little 
curved. Development of audital bul- 
lae about as in Cynopterus. Mandible 
very weak, and ramus distinctly con- 
cave beneath. Symphysis long, its 
greatest diameter equal to about twice 
the distance between outer sides of ca- 
nines. Externally characterized by 
presence of well-developed claw on in- 
dex finger, attachment of wing mem- 
brane to base of fourth toe, and rather low on sides of body. No 
external tail.
