i908.] MAMMALS FROM NORTH CHINA. 641 



horizontal diameter of bullte 14'5 ; length of upper tooth-row 

 (alveoli) 5-3. 



Kah. and Type as above. 



Of the other Chinese Meriones described, this veiy pretty- 

 species may be distinguished from M. unguiculatus by its whitish 

 claws, buffy ears, whiter belly, and less blackened tail ; from 

 M. 'psammophilus by its larger size and bufFy ears ; and from both 

 by its enormously larger bullae, which indicate that it is not 

 really closely allied to either of them. 



11. Mus coNPUciANUs, M.-Edw. 



S . 1551. ?. 1567, 1569. Imperial Tombs, 65 miles E. of 

 Peking. 



c?. 1600. ?. 1599. Near Tai-Yuen-Fu, Shan-si. 5300'. 



c?. 1648. East of Tai-Yuen-Fu. 4000'. 



The Imperial Tombs specimens are very similar to the Kuatun 

 examples considered as typical confucianus by Bonhote, and are 

 equally distinct from the form found on the Ohefoo Peninsula 

 which I have named M. c. sacer in a previous paper. 



" Not common ; trapped among broken rocks and canyon- 

 bottoms on hill-sides." — M. P. A. 



12. Mus WAGNERI MONGOLIUM ThoS. 



c?. 1552, 1566. $. 1556, 1565, 1568. Imperial Tombs, 

 65 miles E. of Peking. 



S. 1611, 1617. ?. 1603, 1621, 1629, 1635. 100 miles 

 N.W. of Tai-Yuen-Fu, Shansi. 8000'. 



Although these mice have no trace of an anterior supple- 

 mentary cusp on their first upper molars, they are not improbably 

 related to the Kan-su Mus " {Leggada) " gansuensis Satvinin, a 

 form evidently of the musculus group, and not a true Leggada 

 at all. 



" This small mouse seemed to be the commonest species in the 

 vicinity of the Imperial Tombs, but still it was not met with very 

 often. It lived under half -buried stones among the grass and 

 bushes, or along the rocky banks of streams. 



" In Shan- si it was somewhat common in the fields and about 

 the peasants' threshing-grounds at Chao-Oheng-shan, but I did 

 not see it elsewhere." — M. P. A. 



13. Apodemus speciosus Temm. 



c?. 1560,1563. $. 1555, 1564. Imperial Tombs, 65 miles 

 E. of Peking.

J. 1623, 1636. $. 1608, 1630, 1631. 100 miles N.W. of 

 Tai-Yuen-Fu. 8000'. 



The Shan-si specimens are not unlike the Korean subspecies 

 A. s. peninsuke, to which perhaps the whole series should be
