 long hair ; arms shorter than legs ; tail half as long as the body except 

 L. catta ; wrists and ankles hairy ; outside of the palm of hand, and at 

 base of fingers are fleshy pads ; mammae two, pectoral. Skull : facial 

 portion elongate ; mastoid region not inflated ; incisors small, subequal, 

 placed in front of canines, which are large and set in a notch on the 

 jaw; all upper molars with an internal cingulum; upper premolars 

 have one exterior cusp, with a supplementary one on the first, and the 

 second premolar has a large interior cusp ; the molars except the pos-
