Abstract P. Z. S. 1910, p. 25 (April 26). 



A white Monkey, with darker underside, hands, and feet. 

 General colour above creamy white ; the hairs white to their 

 bases, mixed, however, with a small number of blackish haii-s. 

 These dark hairs became more numerous on the sides and bellv, 

 where they outnumbered the white ones ; the general tone of the 

 under surface grey, about grey no. 6 or 7 on the belly, darkening 

 to no. 5 on the thi'oat and sides of neck. Outer side of ai-ms to 

 wrists whitish like back, inner side and whole of legs with an 

 equal mixture of dark and light hairs, resulting in about grev 

 no. 9. Hands and feet greyish brown, with a tinge of bistre in 

 it. Tail greyish white throughout. 



Skin of face dark, except the lips, which were white. Long 

 hairs of occiput directed forwards. Hairs of forehead radiatino- 

 from points over the temples with a median o-est between them, 

 but both the whorls and crests diftered considerably in the two 

 specimens. Ear-tufts white, considerably surpassed by the long- 

 brownish hairs which gi'ew from the lower parts of the cheeks. 



A female specimen was whiter throughout, the under surface 

 more nearly whitish, but still darker than the upper surface. 



Dimensions of the type, measured in the flesh : — 



Head and body 565 mm. ; tail 824 ; hind foot 177 ; ear 30. 



JIab. Ko-Khau, Tivang, Northern Malay Peninsula. 



Ti/pe. Adult male. British Museum, No."^10. 10.1.1. No. 1236/10 

 of the Selangor Museum Register. Original number 3184. 

 Obtained for Mr. Robinson by a native collector, 10 January 

 1910. 



This fine Monke}^, which was obviously not an albino, differed 

 conspicuously from all its allies by its white upper and darker 

 lower surface, all other membei-s of the group having the belly 

 lighter than the back. 



Mr. Thomas had great pleasure in naming it after its discoverer 

 Mr. H. C. Robinson, Director of Museums, Federated Malay 

 States, by whose scientific energy our knowledge of Malay 

 Mammalia had been so Ini-gely increased.
