176 MOSTLY MAMMALS 



In 1899 the professors of the Paris Museum were enabled 

 to publish, with excellent coloured plates, the description 

 of a second species of the same group, also coming from 

 Tibet and the adjacent districts of North-Western China. 



This second species, which may be popularly known as 

 the slaty snub-nosed monkey, is fully as large as its more 

 brilliantly coloured relative, which it also resembles in the 

 form of its nose. The tail is, however, much more bushy, 

 and long-haired throughout. And while the colour of the 

 upper-parts and outer and front surfaces of the limbs is 

 dark slaty brown, the cheeks, under-parts, and thighs are 

 mostly pure white ; the naked portions of the face being 

 flesh-coloured. 



The specimens of the slate-coloured species in the Paris 

 Museum were obtained in the north-west extremity of 

 Yun-nan, on the left bank of the River Mekong, in the 

 neighbourhood of Yerkalo, and it seems evident that the 

 species inhabits the crest of the long range separating 

 the valley of the Mekong from that of the Yang-tsi-kiang. 

 During the summer it is probable they frequent that side 

 of the range which overlooks China, while their winter 

 quarters would appear to be the side directed towards 

 Tibet. The native name of " tchru-tchra," or snow-monkey, 

 sufficiently indicates the severity of the climate of the 

 region they inhabit. Probably the Blue River forms the 

 line of division between the distributional areas of the slaty 

 and the orange species, the latter being found in Southern 

 Kansu, Northern Sze-chuan, and Moupin. 



Despite their long isolation from the sphere of European 

 science, one, if not both, of these peculiar monkeys seems 

 to have been known to the Chinese from time immemorial, 

 for in a work entitled " Shan-Hoi-King," or " Mountain and 

 Sea Record," which has been supposed to date from earlier
