Abstract: Twelve items had been measured for the mandibles of 18 adult Macaca mulatta ( male 4, female 14) from Taihang Mountains. Sex dimorphism analysis and variables correlation analysis have been done. The variables of mandible have been compared with the data of the Macaca mulatta living in other regions, some variables have significant difference. Some variables were used to establish discriminant functions by Ottestat method. The discriminant rate reaches 86. 86% . There are positive and negative correlations between various variables, but most of correlation degree are low.
