Mammals of Burma* 



[No. 1, 



of it is that it has two lateral radiating centres of hair upon the crown, the 

 hair meeting and being pressed upwards between them. The small young 

 resemble the adults, excepting that their colours are more strongly 

 contrasted.

The Dusky-leaf Monkey is the most common species of the genus in 

 the Malayan peninsula, from which its range extends at least to the province 

 of Mergui, where it was obtained by the late Major Berdmore. It has also been 

 received from Siam, and is likewise an inhabitant of Sumatra, if not also of 

 Borneo. The adults are blackish, with hair upon the nape lengthened and 

 conspicuously whitish. The newly born young are of a vivid golden- 

 ferruginous colour, which soon changes to dusky-ash, and is continued 

 latest upon the tail.** This may be the species which Mason refers to as 

 being " found, in considerable numbers, in the interior'' of the Tenasserim 

 provinces; but, he adds, "it is not so numerous as the other Monkeys and 

 the Gibbons." He also remarks that "the large flowers of the Dillenia y 

 and many others, are much sought after by these monkeys as food."

The mounted skins of an adult female and young, procured by Heifer 

 somewhere in the Tenasserim provinces, are in the Berlin Museum. By 

 the courtesy of Professor "W". Peters I have been favoured with coloured 

 drawings of those specimens. The mature animal has the upper parts, 

 limbs, and tail blackish, the hairs ferruginous on the basal half; slight 

 band crossing the forehead, cheeks, front, throat, and front of neck, sullied 

 white; rest of the lower parts deep and bright ferruginous, which tinges 

 the inner side of the limbs; face colourless, or pinkish white. Young 

 wholly pale ferruginous, somewhat darker on the hands and feet. There 

 is a slight compressed crest on the vertex, but no distinct whisker-tufts, or 

 lengthened hair on the nape. It is highly probable that some adults are 

 wholly ferruginous, as happens with P. maurus in Java (the so-called S. 

 pyrrhus, Horsf., = $. auratus, Geoff.), and with P. melalophus in Sumatra,
