longer and much sslenderer ; front, of orbit above lu" (in i'onycteris 

 above m'). Premaxilla? similar in form to those of /'Joni/cteris, but 

 more proclivous and fused anteriorly (as in Macroglossus, see 

 fig. 70). Infraorbital canal quite as in Eo)i>/cteris, short, anterior 

 aperture (infraorbital foramen) vertically below or slightly behind 

 anterior point oi" orbital margin, outer wall of canal a bridge of 

 bone as narrow as the thinnest portion of zygoma. Postorbital 

 foramina present. Foramen ovale and rotundum relatively widely 

 separated. Tympanies unmodified. Temporal ridges low down on 

 sides of cranium, a sagittal crest therefore never developed ; hori-

descending in posterior half, coronoid process much sloping back- 

 ward, low, and narrow, top of process little higher than (in some 

 specimens practically at a level with) tip of canines, angular 

 process rounded off ; symphysis not longer thau in Eonycteris 

 (decidedly shorter than in Slarror/lossiis), but extremity of mandible 

 (in front of canines) more drawn out in length, partly to fit to the 

 more proclivous premaxilhe, partly owing to develo]iment of a
