Characters. — Hair radiating from a centre, or divergent all 

 round the face, which is reddish-black ; long and bushy 

 whiskers on the sides of the face and passing behind the ears. 

 Hair generally long. General colour all over, deep black, the 

 hairs tipped with silver-grey in aged individuals ; spot at the 

 under side of the base of the tail white. Length of body, 17^ 

 inches ; of tail, 23^ inches. 



Young. — Uniform reddish-brown, changing soon to the colour 

 of the adult ; the rufous vanishing from the whiskers last of all. 

 The colour of the young is said especially to be the case in 

 females only, and to persist through life ; but, as Dr. Anderson 

 remarks, it is not a common variety, and such coloured adults 

 are highly prized in Java. 



Distril)iition. — Malay Peninsula. Sumatra ; Padang, Bencoo- 

 len, the Lampongs. Java. Billiton. Borneo ; on the Baram 

 river, and also on Mt. Dulit. 



Habits. — These Monkeys ascend the mountains in Borneo 

 to about 2,000 feet ; they are also fairly common in the low 

 country, and are called by the Dyaks " Bigok," and by the 

 Kayans "Chikok," from the noise they make. (C IIc:e.)
