SEilNOPITHECUS. 41 



Distribution. Arakan, the Bassein district of Pegu west of the 

 Bassein river, where I shot this monkey myself, and Northern 

 Tenasserim, near Moulmain, where the same species apparently 

 was obtained by Tickell (J. A. S. B. xxviii, p. 428, and MS. notes) 

 and by Mr. W. Davison. 



In Tickell's unpublished notes there is an excellent coloured 

 drawing and description with several details of anatomy &c., taken 

 from an adult female that he obtained east of Moulmain. The 

 drawing, from which the accompanying cut is taken, represents an 

 animal greyer in colour than Arakan specimens, and the hands and 

 feet are blackish above, contrasting strongly with the colour of the 

 limbs. The lower parts are white on the lower abdomen and 

 inside the thighs only ; elsewhere they are ashy grey. This animal 

 may have been an example of S. albocinereus, Desm. (S. siamensis, 

 Mull. & Schl.), but I am rather disposed to refer that species to 

 S. femoralis. 



Habits. Phayre's Leaf-Monkey is found in dense high 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.

Colour. As a rule dark ashy grey on the head, body, and limbs, 

 varying, however, to blackish brown ; feet and hands black ; lower 

 parts rather paler; tail as a rule lighter than the body. The
