The bare cheeks are enormously outwardly enlarged, the 

 skin of the face and of the great bare area on the guttural sacks 

 being livid black. The skin of the face is sparsely covered 

 with short red hairs, and the forehead also is almost naked. 

 The sides of the upper lip and the chin are clad with long 

 bright maroon-red hairs. The hair on the middle of the head, 

 immediately behind the forehead, is rather short, while that 

 over the temporal and parietal regions is long and directed 

 forwards. On the rest of the head the hair is dark maroon- 

 brown, this colour also extending round the sides of the neck 

 and on to the throat. Between the shoulders the colour is 

 more rufous, whilst down the back it is almost as dark as the 

 head, the sides being also maroon red, as well as the shoulders, 

 the arms being" almost red, and thus paler than every other 

 part of the body. The lower portions of the thorax and 

 the abdomen' are dark chestnut-red. The legs are almost as 

 pale as the arms. The hair on the body generally, and on the 

 limbs is very long, measuring as much as 13 to 14 inches. 



The skull has well-developed sagittal and lambdoidal 

 ridges, and the orbital ridges are also well marked, and the 

 malo-maxillary area is broad. Dyak name, ' Alaias.' Kayan.
