 markings on face or ears. Under surface a beautiful pinkish 

 buff, turning into white anteriorly on the chin, interramia, and 

 lips. Line of demarcation veiy sharply marked, running from 

 upper lip to ankle. Arms brown externally, bufiy on inner 

 aspect ; hands brown, sometimes mottled with white ; hind limbs 

 similarly brown externally and bufFy on the inner aspect ; palms 

 and soles densely hairy. Tail piopoi'tionally shorter than in 

 AI. kathiah, slender, not tufted, uniformly bi^own, the tip not 

 noticeably darker. 



Skull distinguishable from that of all other allied forms by its 

 extremely small size.

Head and body 133 mm. ; tail 54 ; hind foot 22 ; ear 11. 



Skull : condylo-basal length 29-3 ; basal length 27"2 ; zygomatic
