 and back. Lower edge of rhinarium with one lateral notch on each 

 side of the central groove ; postero-superior edge transverse, not, or

 and belly dirty white, more or less mixed with grey or rufous. 

 Pouch absent; mammae 4-1-4 or 5-1-5=9 or 11. Arms and 

 legs deep rufous, hands and feet above dirty white or brown. 

 Fifth hind toe barely reaching to the end of the second phalanx of 

 the fourth ; pads small, very distinct, hallucal pad distinctly sub- 

 divided into two, minute postero-extemal pad present or absent. 

 Tail about two thirds the length of the head and body, its furry 

 portion ceasing after about half an inch below, but tapering gradually 

 backwards on the upper side for about half the length of the tail. 



Skull large and strongly built, with a broad conical muzzle. 

 Interorbital region broad, unridged, its edges gently rounded ; no
