black facial streak well developed, extending from in front 

 of the eye to the outer base of the ear. Ears pale brown. 

 Ilpjier surface of hands and feet whitish or sli<^htly buflfy. 

 ^J\-iil rather greyer than the body, dull drabbj- above, buffy 

 below, its tip apparently regenerated in the type. 



Skull, as compared with that of D. angelus, shorter and 

 proportionally broader, t'le brain-case of the round and 

 inflated shape found in D. robuslus, Mill. Muzzle short, 

 little tapering; nasals nearly parallel-sided, scarcely nar- 

 rowing backwards. Iiiterorbital region short-waisted, the 

 edges square but not ridged. Brain-case peculiarly rounded. 

 Palatal toraniina longer than in avgelus. Bullae higher and 

 more inflated, but shorter antero-posteriorly. 



Dimensions of the type (measured in flesh) : — 



Head and body 94 mm.; tail (? perfect) 68 ; hind foot 20; 

 ear 1 7. 



Skull : greatest length 28 ; condylo-incisive length 25'2 : 

 zygomatic breadth 16"8 ; nasals 8'3x 3; interorbital breadth 

 4'2 ; breadth of brain-case 14 ; combined height of bfain- 

 case and bulljB 11*4; palatilar length 9'8; diastema 6*9; 

 palatal foramina 4; upper tooth-series 4*1.

This pretty dormouse is most nearly allied to D. angelus 

 from the western end of the Thiau Shan, but is distinguished 

 by its shorter and proportionally broader skull, its large 

 rounded brain-case, and its short but high bulla3. I have 

 named it in honour of Mr. J. H. Miller, its actual captor, 

 to whose help and companionship Mr. Carruthers has been so 

 largely indebted. 



" In elm-forest in valley bottom." The specimen was 

 being carried off by a crow, which dropped it on being-

A Dzungarian representative of AI. e. eversnianni, less 

 closely similar to true erythrourus. 



Size comparatively large, larger than in M. e. eversmanni. 

 General colour above more drabby than in the other forms, 

 eversmanni being rather and erythrourus much more sandy 

 or buffy. Under surface with a greater amount of slaty at 

 the bases of the hairs, and therefore less strongly white than 

 in either of the other races, liind feet cream-butT, white in
