ZOOLOGY. 507 
Citellus sp. 
These little burrowing rodents are fairly common on the plains of southern Shan-si 
and the Wei valley in Shen-si. In their general habits they resemble the spermophiles of 
central United States. 
Specimen No. 6035, shot in a wheat-field west of Tung-kuan, Shen-si, March 28, 1904. 
(?) Lepus sinensis Gray. Chinese hare. 
A tawny or buff-colored hare is fairly common upon the plains of eastern China and 
in the less mountainous portions of the four northern provinces. It was not observed 
south of the Wei-ho valley, in Shen-si. 
(?) Vulpes vulpes (var.). Fox. 
The foxes were seen not infrequently in Shan-tung, Chi-li, Shan-si, and Shen-si. In 
the more accessible portions of the mountains most of the underbrush has been destroyed 
by the inhabitants and consequently these animals are met with only in the more remote 
valleys. The foxes which were seen in the eastern provinces, in winter, were distinctly 
grayish in color, but individuals in the Ts’in-ling mountains, in May, were buff or tawny. 
In addition to the species named above, we saw several others regard- 
ing whose identity we have little evidence. These included mice, squirrel- 
like rodents, and a deer which resembles the roebuck. In the gorges of 
the Ta-ning-ho monkeys were not uncommon, but it would be unsafe to 
hazard a guess as to what species is here represented.
