Specimens examined.—Thirty-three, all from North China, as follows: JEHOL: Hsin-lung-shan, 65 mi. NE Peking, 3000 ft., 4. KANSU: 15 mi. S Lanchow, 7400 ft., 1. SHANSI: Chiao-cheng-shan, 90 mi. W Taiyuan, 7000-8000 ft., 4; 30 mi. W Kuei-hau-cheng, 7000 ft., 5; Lung-wang-shan, 20 mi. E Taiyuan, 4000 ft., 10; 18 mi. W Taiyuan, 5000 ft., 1; 50 mi. NW Taiyuan, 5500 ft., 4. SHENSI: 12 mi. S Yenan, 4000 ft., 4.
Apodemus peninsulae, then, is known or suspected to occur over much of southeastern Siberia, Manchuria, Korea and North China. The western limits of its geographic range are unknown. Over this vast area only four subspecies, one newly named, can be ascribed with certainty to peninsulae whereas only two other kinds, giliacus of Thomas from Sakhalin and rufulus of Dukelsky from extreme southeastern Siberia are probably conspecific with it, the latter possibly a synonym of praetor. These considerations underscore the preliminary nature of the present paper. The mammalian fauna of northeastern Asia is scarcely better known today than was that of North America in 1885 when Dr. C. Hart Merriam organized what was later to become the U. S. Biological Survey.
It seems to me that the correct names of four kinds of wood mice discussed above are as follows:
Apodemus peninsulae peninsulae (Thomas, 1907)
Apodemus peninsulae nigritalus Hollister, 1913
Apodemus peninsulae praetor Miller, 1914
Apodemus peninsulae sowerbyi Jones, 1956
