Those of the above mentioned specimens that were taken from 

 Chiao-ch'eng Shan form a topotypical series. This little hamster was 

 first secured from this district by Mr. M. P. Anderson, whose name it 

 bears. This species is very common in Shansi and Shensi, but is 

 comparatively rare in Kansu. Chinese name, " Tsang-erh," means 

 " storer."

? 103. Yu-Hn Fu, Shensi. Alt. 3000 ft. November i8th, 1908. 



This hamster seems to take the place of C. andersoni in and on the 

 borders of desert country. It is also recorded from Chihli and Shantung. 



Its burrows are usually to be found along the sides of cultivated 

 fields, irrigation ditches, and watercourses. Chinese name, " Ts'ang- 

 kuan," or " granary official," from its storing habits.

This hamster was originally placed in the genus Cricetulus by Mr. 

 Thomas. It was noticed, however, by Mr. Miller that the sole of the foot 

 instead of having several small distinct pads, as is the case in other 

 hamsters, has a single large pad formed by the coalescence of the usual 

 pads. For this reason he created a new genus Phodopus. 



In appearance this species differs markedly from the hamsters 

 hitherto mentioned. In colour, it is pinkish buff above and pure white 

 beneath. The tail is very short, and the soles of the feet are thickly 

 covered with white hairs, which enable the little animal to progress with 

 ease over the deep loose sand. Extremely common. Present series are 

 topotypes. Specimens have also been recorded from Wu-chai Hsien, a 

 town situated on a plain on the west of the Ning-wu Fu mountains, in 

 Shansi. Chinese name, " Mi-tsang," meaning " storer of millet."
