SINO-MONGOLIAN FRONTIER 
35. Allactaga mongolica, Radde. 
One specimen, 2. 100 miles W. of Lama 
Miao, Mongolia. 4,000 ft. 
One specimen, 2. 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 4. 
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-tzii_ (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 sight. 
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 swinhoet sowerbye, Hollister.
