two phalanges besides the metacarpal bone; the third or longest 

 finger with the first phalanx bent upwards in repose, but not resting 

 on the dorsal surface of the metacarpal, being prevented by the 

 great length of the index finger. Tail very long and slender, 

 produced far beyond the posterior border of the short iuterfemoral 

 membrane. 



Dentition : i. ^, c. ~^, pm. ^^, m. ^. Upper incisors rudi- 

 mentary. The small premaxillary bones are united in the middle, 

 and connected by curved lateral processes with the maxillary bones. 

 Nasal bones much expanded laterally and vertically ; frontal bones 

 depressed, forming a shallow concavity in the forehead. 



This genus contains a single species ranging from Egypt and 

 Kordofan to the Malay Peninsula.

From the frontal hollow crossed by the band connecting the ears 

 a deep furrow leads to the nose and terminates behind the fleshy 

 prominence that forms the upper part of the truncated muzzle. 

 The bluntly pointed tips of the ears laid forwards just extend to 

 the edge of the muzzle ; the margins of the ear-conch are convex, 

 the outer terminating behind the angle of the mouth just in front 

 of the base of the tragus. The tragus is much longer than wide, 

 the tip very obtuse, outer margin slightly convex with a lobe at the 

 base, inner margin forming an ogee curve, the concavity above.
