摘　　要：本文研究了中国大陆东部地区黑线姬鼠的形态差异,根据鼠体背部黑线的清晰度和背部毛色以及某些外形性状的差异系数,提出中国东部地区黑线姬鼠可分为2个亚种,即东北亚种A. agrarius. manchuricus和长江亚种A. a. ningpoensis。原华亚种A. a. pallidior从分类特征上看,其秦岭、淮河以北地区的应归入东北亚种,其南的应属长江亚种。东北与长江亚种分界线大致与中国动物地理区划中的古北界和东洋界在我国东部的分界线相一致。This paper describes the morphological difference of A, agrarius from different areas in eastern continental China. The author suggests that A. agrarius can be divided into two subspecies after the comparison of the clearness of the black dorsal stripe and the colour of their dorsal hair. The two subspecies are: A. a. manchuricus and A. a. ningpoensis. A previously claimed subspecies -A.a.pallidior shows no distinctive feature over the classification. Samples of A.a.pallidior taken from north of Qinling Mountains to the Huai River line have very similar dorsal coloration and black stripe with that of A,a.manchuricus, while samples taken from south of the above line have very similar dorsal coloration and black stripe with that of A. a. ningpoensis. The distribution of A. a. manchuricius and A. a, ningpoensis is demarcated along the Qinling Mountains to Huai River line which is also the eastern boundary of the Palacarctic Realm and Oriental Realm in China's animal geographic division.
