MamnmK<t from Central Asi'n. 403 



with dull soiled butl'y, conspicuously different from the 

 whitish tone occurring in E. tancrei and all'icatus. Facial 

 darkening medium, less extended than in E. fusciceps. Tail 

 quite short, its longer hairs buffy. 



Skull large, rouiuled. Aiiteorbital foramina narrow, their 

 outer edges more vertical than in E. albicatus. Interparietal 

 more nearly square than in other species, their antero- 

 posterior diameter greater and their transverse less. Palatal 

 foramina rather shorter than in E. albicatus. 



Incisors heavy, thrown forward as in E. tancrei^ more so 

 than in E. fusciceps. Molar series rather shorter than in 

 E. albicatus, M^ fairly uniformly of the shape and com- 

 plexity shown in Biichner's tigures 9 to 11. 



Dimensions of the type (measured in liesh) : — 



Head and body 120 mm.; tail 15 ; hind foot 21. 



Skull : condylo-basal length 33'6 ; condylo-incisive length 

 35"(i ; zygomatic breadth 2-1 ; nasals 9 ; interorbital breadth 

 (j ; interj)arietal 3'3 X G"5 ; distance between outer corners of 

 anteorbital foramina 0*5 -, palatilar length 18*5 ; diastema 12 ; 

 palatal foramina 3"2 ; upper molar series, crowns 7'5, 

 alveoli 8*1.

Its dark-coloured under surface and squared interparietal 

 will diiitinguish this Ellohius (voxw E. albicatus^ the only other 

 species which equals it in size. 



Two examples from the Tekes Valley, which opens into 

 the Muzurt Valley, collected by K. Wache in 1904, also 

 seem to be referable to E.coenosus, though their interparietals 

 are not quite as in Mr. Carruthers's series. No doubt it will 

 be found to be widely spread over the western part of the 

 Thian Shan.

(?. 290; ?. 2S9, 292. Barlik Mts. (S. side), N.W. 

 Dzungaria. 7000'. 



Similar to true fusciceps in essential characters, but the 

 general colour decidedly darker, the back " broccoli-brown " 

 scarcely tinged with buff, instead of the uniform pale 

 "pinkish buff" of the Samarkand form. Under surface also 

 more muddy coloured. 



Skull apparently not differing in any important respect 

 from that oi fusciceps, though the incisors are perhaps a little 

 stouter, looking dispioportionately heavy for the size of the 

 skull.
