220 SOME CHINESE VERTEBRATES. 
is more or less obsolete; in six or seven it is scarcely noticeable except as a slightly 
darker median band. There is said to be no trace of a dorsal stripe in the type 
specimen of this race. In size and cranial measurements our specimens seem to 
agree with the dimensions given by Bonhote (1905, p. 397). Mr. Zappey did 
not obtain this species higher up the valley so that it may be of lowland distribu- 
tion. Bonhote, however, records A. a. manchuricus from southern Shensi. 
APODEMUS MINUTUS PYGMAEUS (Milne Edwards). 
A young, though nearly full-grown specimen was taken at Changyanghsien, 
Hupeh, November 16, 1907, but elsewhere the species was not met with. It was 
originally described from Szechwan by Milne Edwards, and Bonhote (1905) 
records specimens in the British Museum from Kuatun and Shanghai. 
APODEMUS SYLVATICUS DRACO (Barrett-Hamilton). 
A series of twenty-five specimens of the long-tailed field mouse seems, after 
careful comparison, to represent but this single race, although they come from 
widely separated localities, namely:—Changyanghsien 8,000 feet, Fanghsien, 
8,500 feet, and Showlungtan, Hupeh; Mohsimien 8,000 feet, Washan, 6,000 to 
9,000 feet, Lianghokow, 12,000 feet, and Tachiao, 12,000 to 13,000 feet, in 
Szechwan. About one third of the specimens have acquired the mature colora- 
tion, a bright russet or ochraceous buff above and on the sides, with a dorsal 
black area while the remainder exhibit various darker shades in which black 
hairs predominate on the back and are mixed on the sides to a less extent. The 
tails of these darker individuals are much less markedly bicolor than those of the 
russet-colored adults. One of the latter from Washan is almost clear orange- 
ochraceous, on the nape, shoulders, and sides, with but a slight admixture of 
black hairs on the lower back. The collector’s measurements for seven adults 
average :— total length, 184 mm., tail, 95, hind foot, 23. Bonhote (1905) gives 
186, 95, and 20 respectively. The skull of No. 7139, from Fanghsien measures :— 
greatest length, 26.8; basal length, 21; palatal length, 12; upper diastema, 7; 
incisive foramina, 4.5; nasals, 10.8; breadth of brain case, 12; upper molars, 
4.4. These dimensions agree very closely with those given by Bonhote for 
specimens from Kuatun, northwest Fukien. 
APODEMUS MAJOR (Radde). 
In the high mountains of western Szechwan near the eastern borders of 
Tibet occurs a large field mouse evidently related to A. sylvaticus, that I have
