690 MR. OLDFIELD THOMAS ON 



I find that the true E. c. hUicolor is a pale desert form peculiar 

 to the region towards the Ordos desert, that the present S. 

 Shen-si specimens are, as is geographically correct, intermediates 

 between the A\ c. sacer of Shantung on the east and the Kan-su 

 form on the west, and that the latter is sufficiently differentiated to 

 have a special subspecific name of its own. It may be called 



Epimys confucianus canorus, subsp. n. 



General colour approximating to " clay-colour," slightly darker 

 and more tawny than in sacer, much darker than in luticolor, 

 lighter than in confihcianus. Median darker dorsal line averaging 

 more distinct than in confucianus, less than in sacer. White of 

 under surface more markedly tinged with buffy or cieam- colour 

 than in the other subspecies (but there is a doubt as to how much 

 this fades after death). Metatarsals without, or with but slightly 

 marked, darker patches. Tail with the dark colour of its upper 

 surface passing nearly or quite continuously to the end ; its tip 

 hardly so heavil}'^ tvifted as in sacer. 



Skull about as in confuciamts and luticolor, smaller than in 

 sacer. 



Dimensions of the type, measured in the flesh : — 



Head and body 120 mm.; tail 180 ; hind foot 27 ; ear 21-5. 



Skull : greatest length 34'5 mm. ; condylo-incisive length 30"5 ; 

 upper molar series 6. 



JIab. Southern Kan-su, grading eastwards into sacer and south- 

 wards into true confucianus. Type from Wen-hsien Country, 

 S. Kan-su.
