Abstract: Variables on mandible of adult M. mulatta in Taihang mountains have been measured and calculated. Allometric analysis between variables on the mandible and maximum cranial length has been made.Comparison and cluster analysis on variable of mandible among Henan, Hunan and Hubei，Fujian and Guangdong provinces in China have been made. The results showed that correlative coefficients between variables on the mandible and maximum cranial length are lower （|r|＜0.7）. Mandible of M. mulatta in Taihang mountains is the robustest. The distance between Henan and Hunan and Hubei provinces is nearer than Henan and Fujian and Guangdong.

Key words: Mandible, Taihang Mountains, Macaca mulatta, Allometric analysis, Cluster analysis
