1908.] MAMMALS FROM NORTHERX CHINA. OTO' 



In this series there is a marked difference between the sexes, 

 the male skulls being mai'kedl}'' lai-gei-, more rugged and lieavily 

 ridged than the female. Mr. Lyon had stated that his specimen, 

 was a female, but on my sending him a pair of the present series. 

 for comparison, he has been good enough to inform me that the 

 male agreed precisely with the type, and that the latter was 

 evidently wrongly sexed. 



" This small I'odent mole is rather common, for traces of it, old or 

 new, may be found in' nearly every field in those parts of Shan-si 

 and Shen-si visited. It is, however, diliicult to trap ; we secured 

 the present series chiefly by hiring peasants to dig the animals 

 out and bring them to us. In walking on the surface of the 

 ground the rodent mole turns the long claws of the fore-feet under 

 the soles and walks upon the backs of the claws ; they make but 

 slow progress. When frightened or angered this animal utters a 

 peculiar little squeal. We had many live ones in the couise of 

 our work at Yu-lin-fu and elsewhere, but did not find them 

 inclined to be savage.

 1793, 1826. Yu-lin-fu, 8hen-si. 4000'. 



Dipus soiverhyl was obtained by Mr. Sowerby at Yu-lin-fu and 

 described in a special paper *. It is the first three-toed Jerboa 

 discovered in the Far East, the five-toed Allactaga mongolica 

 having been hitherto the only known Chinese Jerboa. Reasons 

 for the separation of the genus D'qms from the earlier Jacidas are 

 given in the paper quoted. 



The species is probably characteristic of the Ordos Desert and 

 its vicinity. 



" Inhabits the sand-dunes."— J/. P. A. 



30. Allactaga mongolica Radde. 



S . 1978. Ning-wu-fu, Shan-si. 6000'. 



" Inhabits the loess plain near ISTing-wu-fu, where its tracks are 

 fairly plentiful. On the plateau west of Ning-wu we saw tracks- 

 which were probably made by this animal, but we were unable to 

 identify its burrow, and could not secure a second specimen." —
