This species is nocturnal in its habits, in which respect it agrees with 

 M. psammophilus, and differs from M. unguiculatus. Usually found in 

 colonies. M. auceps seems to prefer bushy country, and its burrows occur 

 in patches of thorn scrub or other protective bushes. 



M. unguiculatus is found on the open plains of Mongolia, away from all 

 bushes, and M. psammophilus on plains and in river valleys of the northern 

 provinces. The latter seems to prefer sandy places. Chinese name, 

 " Huang-shu," meaning ** yellow rat."

This rat is a rock-loving species, being found usually along the rocky 

 sides of ravines and valleys in both Shansi and Shensi. Easily trapped, 

 and frequently found to be covered with fleas and ticks. A new flea 

 {Ceratophyllus suhcaecatus)\ was taken from one of the Yen-an Fu specimens.
