570 Mr. O. Thomas on 



Of tlie two small voles of this region I assigned, in my 

 paper on tlie Carrntlieis mammals, tlie name evers7nanni, 

 Poliakoff, to the Microtus, and not to the Stenocranius, on 

 the ground tliat Biichner's figure of tlie skull clearly indicated 

 a MicTotus and that, as he mentions Poliakofi's original 

 specimens, this figure might be supposed to be taken from 

 one of them. Whether Biichner''s Przwalski sprcimens 

 were of the same form or not did not affect the question. 



kSince I wrote, however, Mr. Hollister*, in agreement 

 with Kashtchenko, has again put eversmanni into Steno- 

 cranius, and I therefore now accept his conclusion, at least 

 until an expert examination can be made of the types in 

 St. Petersburg. 



2Q. Microtus [Stenocranius) tianschanicus, BUchn. 



Four specimens. 



"In die Schlucht Tischkan." 



27. Allicola worthingtoni suhluteus, subsp. n. 



(J. 324 ; ? . 323. "In die Schlucht Tischkan.'' 



Like true worthingtoni in all essential characters, but the 

 pure white of the end of the hairs of the lower surtace 

 replaced by "pale pinkish buff" (Ridgvvay, 1912). Hands, 

 feet, and tail alto with a slight huffy tinge. 



Skull and teeth as in uorihing/oni. 



Dimensions of the type (measured in flesh) : — 



Head and body 95 mm.; tail 40; hind foot 20; 

 ear 16. 



Skull : greatest length 26*5; upper tooth-row 5*7. 



Ti/pe. Slightly immature feinale, B.M. no. 14. 5. 10. 186. 

 Original jiumber 323. Collected 20!h July, 1913. 



28. Ellohius wsulus, Thos. 



Seventeen specimens. " In die Schlucht Malaja-Aksu." — 

 W.R. 



This series shows well how the colour intensifies as age 

 advances, the younger specimens being greyish buf¥, while 

 the older ones attain a rich cinnamon. 



I can find no tangible difference between the Djarkent 

 examples and the three original specimens obtained by 

 Mr. Carruthers on the southern slopes of tlie Barlik Mountains. 



By the help of this series, however, I am now able to 

 distinguish the skull of ursulus from that of the Samarkand 

 * Troc. U.S. Nat. Mus. xlv. p. 516 (lOl'!).
