APES AND MONKEYS. 
lofty situations.” There is a record of one of these monkeys having attacked a 
native laden with a hag of rice. 
The Capped Langur (Semnopithecus pileatus). 
Of somewhat smaller dimensions than the hanuman is the capped langur of 
Assam and the neighbouring districts of North-Eastern India and Upper Burma. 
This species may be readily distinguished from the Nilgiri langur and the purple¬ 
faced monkey (with its varieties) by the hair of the crown of the head being longer 
than that on the occiput and temples, thus having somewhat the appearance of a 
cap, from which character the species derives its name. 
In colour this monkey varies from a dusky-grey to a brownish ashy-grey on 
the upper parts; the upper part of the back, and sometimes also the crown of the 
head, being darker. The hands and feet are dark or black above, but occasionally 
some or all of the fingers may be yellowish. The tail is dark-brown, but may be 
black at the tip. The face is always black, but the sides and lower parts of the 
head, as well as the neck, vary from a golden brown or orange to a pale yellow or 
yellowish-white tint. The light colour of the sides of the face extends backwards to 
a line just above the ears, so that, with the light-coloured nape of the neck, the dark 
cap is well defined, and gives to this monkey a peculiar and distinctive appearance. 
According to Mr. Blanford, nothing is known of its habits in a wild 
state, although they are probably very similar to those of most of the other 
species of the genus. In captivity it is said to be gentle if captured when quite 
young, but if not taken till adult it is morose and savage, this being especially the 
case with old males. 
The so-called red-bellied langur (S. chrysogaster ) is only known by an adult 
female and a young one preserved in the Museum at Berlin, and reputed to have 
been obtained from Tenasserim. In the adult the upper parts, the limbs, and 
the tail are jet black, with the lower portions of the individual hairs ruddy, and 
their extreme bases white ; the band on the forehead, as well as the cheeks to behind 
the ears, and the sides and front of the neck, together with the chin and the upper 
part of the breast are pure white. The remainder of the under parts are of a deep 
bright ferruginous red, which also tinges the inner sides of the limbs, and gives 
the animal its distinctive appellation. The young are of a uniform reddish-white 
colour. The head of the adult appears to have a small crest, and by this it is 
distinguished from the typical capped langur. 
From this description it would appear that this monkey is the most brilliantly 
coloured of all the langurs; and Mr. Blanford considers from this circumstance that 
if it really comes from Tenasserim other examples ought ere this to have been 
obtained. Dr. Anderson regards this monkey merely as a brilliantly coloured 
variety of the capped langur, but this view is not accepted by Mr. Blanford. 
The Dusky Leaf-Monkey {Semnopithecus obscurus). 
The dusky leaf-monkey, which is found in Siam, the Malay Peninsula, and the 
Tenasserim provinces, while agreeing with the Nilgiri and the capped langur in
