Closely allied to this splendid monkey, if indeed it be not 

 a pale variety, as we strongly suspect, is a Semnopithecus, 

 several specimens of which were brought by the late Sir Tho- 

 mas Stamford Raffles from Sumatra, and described by him 

 under the title of Simla melalophos, in the thirteenth volume 

 of the c Linnean Transactions.' Recently the same animal, 

 as the specimen in the Museum at Paris proves, has been de- 

 scribed by Isidore Geoffroy, in the ' Supplement to Belanger's 

 Travels,' under the title of Semnopithecus Jlavimanus ; its 

 distinguishing character consisting in the yellow colour pre- 

 vailing on the lower portions of the extremities, the same 

 parts in the former species being bright rust. If admitted as 

 distinct from its more richly coloured congener, it will stand 

 as follows. 



S. Jlavimanus ; Isid. Geoffroy. Sempai. 



General colour sandy red, slightly washed with dusky black ; occiput, 

 neck, chest, and under parts, whiteish ; vertical crest long and peaked, the 

 sandy red passing into black at its point. Fore arms and legs pure pale 

 sandy yellow. Fur full, long, and falling. Palms of hands, soles of feet, 

 and nails, black. General form that of S. cristatus. 



Length 1 foot 7 inches ; tail 2 feet 3 inches. 



Habitat Sumatra. 

 Syn. — Simla melalophos. Raffles, in Linn. Trans, vol. xiii. 

 Simpai of the Malays. 



S. Pyrrhus ; Horsfield, in i Zool. Researches.' 



General colour bright sandy red, or fulvous ; hair long, soft, and silky, 

 very full on the head, where it forms a bushy, but not a pointed, tuft. — 

 Hands and feet pale yellow. Nails yellowish white. 



Length 1 foot 7 inches ; tail 24 inches. 



Habitat Java. 



This beautiful species is closely allied to the preceding, 

 from which, however, it is sufficiently distinguishable. It 

 has been confounded by most writers with the following, from 

 which we regard it as separate.
