A small, slender, inconspicuous species with a general grayish 
brown appearance, darkest on the back. I could not find the skull 
but Anderson who gives a description of it says it “has the interorbital 
space of moderate length, the forehead rather full, but the supra 
orbital ridges are not strongly developed, while the external orbital 
angle of the frontal is rather prominent in adults.” He gives no 
measurements of the skull, but only those of the body and tail, viz.: 
length of body, (head supposedly included), 462; tail, 539. Blanford 
states (1. c). that Phayre’s Leaf Monkey, as he calls this species, is 
“found in dense forests, or amongst bamboos on the hill sides.and on 
the banks of streams, usually in flocks of twenty or thirty individuals. 
It is very shy and wary, and is consequently more often heard than 
seen, the whole flock when alarmed rushing through the forest shaking 
the branches violently and leaping from tree to tree. But occasionally, 
as Tickell observes, an old male stays behind in a safe post of vantage 
on the top of one of the highest trees, where he may be heard uttering 
his short, deep, alarm-cry at frequent intervals. This cry is an angry 
bark, not unlike that of the Hanuman. I was once well scolded from 
a tree by an old monkey, I believe of this species, on the edge of a 
half deserted clearing in Southern Arakan. I had done nothing to 
offend his monkeyship, but he evidently considered me as something 
unusual and suspicious. Blyth observes that the young of this species, 
besides making a whining noise to express their wants, emit a cry that 
might be mistaken for the mew of a cat.”
