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 3 , pm 2 , pm 8 ) with the crowns 

 compressed and elevated into distinct though blunt cusp, the others 

 {pm 4 , m 1 , m 2 , pm 4 , m u m 2 , m 8 ) with narrow nearly flat orowns 

 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 Gynopterus. 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.
