282 Mammals of Eastern Asia 
pallidior from Shantung and Hopei, and A. a. mantchuricus 
from northern Hopei. The last named extends into Manchuria. 
In Korea is found the race A. a. corece. The general color in the 
A. agrarius group is reddish brown, underparts dull white. The 
dorsal stripe, characteristic of European A. agrarius, tends 
toward obsolescence in the races of southern China. The num- 
ber of nipples is 8. The Mice of this group prefer semi-open 
habitats to forests. The size in the various races is quite vari- 
able; head and body about 4 inches, tail about 3% inches, hind 
foot % to % inch. 
The A. sylvaiicus group, subgenus Sylvczmus, occurs from 
western Europe to eastern Siberia and south into the Himalayas. 
A. s. wardi occurs in Ladak. Both the geisha group and the 
speciosus group have been regarded as parts of Sylvcemus. The 
members of the subgenus Sylvcemus are reputed to prefer 
forested conditions, in contrast to the field habitats affected by 
A. agrarius and its relatives. 
Apodemus speciosus and races seem to represent A. sylvaticus 
in the Orient. All are perhaps only races of sylvaticus. The 
forms in eastern Asia include A. s. major from Amur, A. s. 
giliacus from Sakhalin, A. s. peninsulce from Korea and 
Hopei, A. s. rufulus from Ussuri, A. s. praetor from Manchuria, 
A. s. speciosus from Japan; and farther south A. s. draco from 
Hopei and Fukien, A. s. orestes from Hupeh, Yunnan, Szech- 
wan, and northern Burma. Apodemus semotus for Formosa, 
A. latronum from Szechwan, A. ilex from Yunnan and northern 
Burma, and A. rusiges from Kashmir are species belonging to 
the sylvaticus group. 
Typical Japanese A. speciosus is bright reddish brown above, 
beneath white, including the lips and hands and feet. Length of 
head and body is about 4 inches, tail 3% inches, hind foot 1 inch. 
Several darker related Japanese races have been distinguished. 
The number of nipples is 8, 6 in the Formosan A. semotus 
(6000 to 8000 feet). The race prcetor of the mainland adjoin- 
ing Japan is larger ; its corresponding dimensions are 4% inches,
