Characters. — Nearly related to S. obscurus. Hair on the side 

 of the head, and in front of the ears, long, projecting outwards; 

 that on the top of the head long and directed backwards; beard 

 short; face almost nude, bluish-black; lips thinly furnished 

 with short yellowish hairs. General colour of the body every- 

 where black, except on the shoulders, the fore-limbs to the 

 wrist, the joint of the legs, the back and sides of the head, 

 and tail, which are washed with pale grey. Length of body, 

 19^ inches; of tail, 29 inches. The adult female is similar 

 in coloration to the male. In the skull the orbits are rounded, 

 and the inter-orbital region elongated. Dr. Anderson observes : 

 "The differences which exist in certain dimensions between 

 the skulls of well-authenticated examples of the two sexes are 

 far greater than are generally found in the same sexes of dif- 

 ferent species." 



Distribution. — Northern Tippera hills; Assam; and Mount 

 Mooleyit, in Tenasserim. Dr. Anderson observed it in the 

 Valley of the Tapeng, in the centre of the Kachin hills in 

 Upper Burma, and in the defile of the Irawaddy. 



HaMts. — This species inhabits the thick forest, and is found 

 in troops of from thirty to fifty individuals, distributed, accord- 

 ing to Dr. Anderson, over three or four high forest-trees over- 

 hanging the mountain streams. It is generally tame and fearless.
