摘　　要：明纹花鼠是东南亚地区的特有种,在中国有3亚种(阿萨姆亚种、滇西亚种、滇南亚种),分布于藏东南、云南西南部和南部。以往主要根据外部形态特征进行分类。为探讨3亚种头骨性状的差异,在测量15个性状的基础上,运用统计分析软件SPSS11.0对其可测量性状进行多变量分析。结果及推测如下:①明纹花鼠3个亚种的地位是确定的。②在头骨15个性状中,两两亚种之间具有显著差异的性状:阿萨姆亚种与滇西亚种有8个(枕鼻长、吻宽、颧宽、眶间宽、后头宽、鼻骨宽、下齿列、下颌骨高);阿萨姆亚种与滇西亚种有7个(颅全长、枕鼻长、颧宽、眶间宽、后头宽、下颌高、下颌骨高);滇西亚种与滇南亚种有4个(吻宽、后头宽、鼻骨宽、下颌高)。③滇南亚种与滇西亚种之间的亲缘关系近于两者各自与阿萨姆亚种之间的亲缘关系。Tamiops mccleUandi is a species endemic to southeastern Asia. We obtained data on 15 cranial characteristics from three currently recognized subspecies of T. mcclellandi that used to be classified by pelage characteristics in China （T. m. mcclellandi, Tmm ; T. m. collinus, Tmc ; T. m. inconstans, Tmi） and which are distributed in southeastern Tibet, and in the south and southwest of Yunnan）. We analyzed the data with SPSS 11.0 （Multivariate Analysis） in order to examine whether significant differences exist in cranial characteristics among three subspecies, to evaluate their subspecies validities, and to examine relationships among them. The results indicate： 1. The three groups are all valid subspecies. 2. Among 15 cranial characteristics, eight characteristics （ONL, ROB, ZOB, IOB, MTB, BN, MDL, HM）between Tram and Tmc were significantly different; seven characteristics （GLS,ONL, ZOB, IOB, MTB, MH, HM） between Tmm and Tmi were significantly different; and four characteristics （ROB, MTB, BN, MH） between Tmc and Tmi were significantly different. 5. Relationships between Tmc and Tmi are closer than those between each of the two subspecies and Tmm.
