Kayans 'Kaladi,' and is common everywhere. It is usually 

 seen in large numbers, and some thirty or forty often pass one 

 in the jungle, darting from branch to branch and making a 

 tremendous noise. They will sometimes, when barked at by 

 a dog, attack it and inflict a very bad bite. They ascend the 

 mountains to the height of 3,000 feet ; but at that height the 

 colour of their hair becomes of a much deeper red. They are 

 very destructive in the fruit gardens."

Characters.— Adult Male.— Size, proportions, and coloration show- 

 ing a general resemblance to the S. jemoralis group, the pre- 

 vailing colours being black and white. While, however, the 

 forehead, the fore-arms and hands, lower legs and feet, and tail 

 (both above and below) are all deep glossy black, the back 

 itself, with the occiput, nape, and shoulders, is brown. Thighs 

 along a narrow strip on their outer aspect, ashy grey, darkening 

 distally into the black of the lower legs, but their posterior 

 aspect, continuous with their inner sides, is perfectly white, 

 giving a very peculiar and characteristic appearance to the 

 animal, and one which is quite unlike any species known 

 to us, with the one exception that M. siamensis has whitish 

 patches in somewhat the same position. Whole of under 

 surface, with the sides of the neck, the hairs on the inside of 

 the ears, and lines down the inner sides of the arms and legs, 

 pure creamy white. Face thinly haired throughout, the hairs 

 black, except those on the nose, where there is a whitish patch. 

 Forehead with the hairs radiating outwards and backwards
