Abstract: This paper describes the morphological difference of A.agrarius from different areas in eastern continental China. The author suggests that A.agraxius can be divided into two subspecies after the comparison ofclearnessof 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.pallldior shows no distinctlve feature over the classification．Samples of A .p.palldior taken from north of Qinling Mountains to the Huai River line have similar dorsal coloration and black stripe with that of A .a.menchuricus,while samples taken from south of the above line have very similar dorsal coloration and black stripe with that of A.a.ningpoensis.
The diatribution of A.a.manchuricius and A.a.ningpoensis is demarcated along the Qinling Mountains to HuaiRiver line which is also the eastern boundary of the palaearctic Realm and Oriental Realm in China`s animal geographic division.
