where. Reported to exist round Lan-chou Fu in Kansu, but none were 

 seen. Chinese name T'iao-t'u-tzu, meaning "Jumping Hare." This is 

 ascribed by Giles to the Siberian Jerboa.

On a previous visit to this locality, several specimens were secured, 

 but on the present visit I could scarcely find any inhabited burrows, and 

 had much difficulty in trapping this single specimen. 



This species was described by Mr. Thomas from specimens in their 

 summer pelage, taken in Shansi at Ning-wu Fu, in igo8. Those taken 

 from Yen-an Fu on the same expedition being in their winter coats. 

 The U.S. National Museum now possesses specimens in winter pelage 

 from both localities. Those from Shansi are found to be somewhat 

 darker and more ochraceous in colour than those from Shensi. In other 

 respects the specimens from both places agree closely. 



The present specimen from Yen-an Fu agrees exactly with those 

 taken from almost the same locality in March, 1908. 



Chinese names "Hao-t'u" meaning "rat-hare" and "Ti-t'u" meaning 

 " ground-hare."
