Abstract: In this article, 21 pelvic variables of 22 Macaca mulatta (11 males and 11 females) in Taihang mountain were measured by the method suggested by Wu Rukang et al. and Shao Xiangqing. The results were briefly summarized as the following.
1. The analysis of correlation, R cluster and regression relationship illustrated that the pelvic variables measured showed positive correlation and that there were different degrees of correlation in different variables of the pelvis. There were significant regression relationship among some pelvic vari- ables such as X1, X12 and X13.
2. Therewere no significant sexual differences between the male and female among majority of the pelvic variables (76. 19 %) except X1, X7, X11, X12 and X13. Most of the pelvic variables of the male were larger than the females except X3, X4, X7 and X11.
3. The results indicated that sexual dimorphism were very significant among some pelvic variables. It was one of the criteria to judge the sex with morphological characteristics.
