SINO-MONGOLIAN FRONTIER 



35. Allactaga mongolica, Radde. 



One specimen, ?. 100 miles W. of Lama 

 Miao, Mongolia. 4,000 ft. 



One specimen, ?. Tabool, 100 miles N. of 

 Kalgan, Mongolia. 4,000 ft. 



In both specimens the comparative short- 

 ness of the ear and hind foot confirm Mr. 

 Miller's distinction between this species and 

 the Kansu allactaga, which he named A, 

 mongolica longior. Though common enough 

 in some districts, the Mongolian allactaga is 

 very difficult to secure. The two specimens 

 were caught by us in broad daylight, by 

 riding them down on horseback. The first 

 sought refuge in a short burrow and was 

 easily dug up ; the second was chased into a 

 shallow lagoon, which it very nearly succeeded 

 in crossing by repeated jumps. The Mongol 

 name is " Allactahai " ; the Chinese name is 

 T'iao-t'u-tzu (meaning "jumping hare"). 

 The Mongols have a superstition that the 

 allactaga sucks the milk of cows, and it is one 

 of the few animals that they will kill on sights 



It is semi-diurnal in its habits, and may 

 be seen skipping about in the twilight or 

 early morning. It refuses to enter a trap or 

 to take any bait. 



36. Lepus swinhoei sowerhyce, Hollister. 



Two specimens, S^. Wu-tsai, 20 miles W, 

 of Ning-wu Fu, Shansi. 6,000 ft. (?)
