This paper deals with the distribution and habit of Yunnan snub-nosed monkey.According to our investigations,the distribution of Yunnan snub-nosed nokeys is limited in Yun-ling mountain ranges within the area of 98°40′-100°00′E,and 26°30′-31°00′N.They dwell in the dark forest of conifers with an elevation of 3350 to 4000 meters and seldom get down to the ground.Their food is considerably specialized and they take the leaves of China fir as their main food.This food habit is very rare among primates.
