OCHOTONA (OCHOTONA) HUANGENSIS (Matschie) 



Conothoa huaugensis Matschie, Wisseus. Erg. Exped. Filehner China und 

 Tibet, vol. 10. pt. 1, 1908, p. 214 (between Sianfu and Lanchow, Kansu, Cliiua). 



Specimen. — One from 30 miles west of Sininf;, Kansu. 



From the description of this race one infers that it is a member of 

 the dauuHca group. The above specimen is comparable to this in 

 color, and the bullae are about the same size but larger than in lyed- 

 fordi, as Matschie said. The pelage, however, is of an entirely dif- 

 ferent quality, being relativelj'- short and very woolly — not coarse as 

 in dmmn'ca and its allies. The skull, too, is considerably more arched 

 and the interorbital ridging is sharp and pinched in. The claws are 

 entirely black and very long, although the latter feature may, of 

 course, be due to local conditions. 



OCHOTONA (OCHOTONA) ERYTHROTIS VULPINA A. B. Howell 



Ochotoua (Ochotona) eryihrotis vuJpina A. B. Howell, Proc. Biol. Soc. 

 Wash., vol. 41, 1928, p. 117 (30 miles we.st of Sluing, Kansu, China). 



Specimens. — Three: the type and two topotypes. 



Apparently this is the only Chinese subspecies of true erythrotis, 

 having a summer coat that is of an inten.se reddish hue and with 

 hairs entirely lacking blaek tips. It is of interest that this new race 

 and a specimen of huangensh were secured in the same locality. 



OCHOTONA (OCHOTONA) GLOVEKI Thomas 



Ochotoiin gloveri Thomas, Ann. Mag. Nat. Hist., ser. 9, vol. 9, 1922, p. 190 

 (Najrchuka, Szechwan, China). 



Specimen. — One from the type localit}'. 



In addition to the cinnamon ears, this August topotype has the 

 nose of the same color. The relationship of this form to the species 

 erythrotis can be considered as no nearer than specific. 



OCHOTONA (OCHOTONA) CHINENSIS Thomas 



Ochotona {Ocliotonn) ch'mcnsli< Thomas, Ann. Mag. Nat. Hist., ser. 8, vol. 8, 

 1911, p. 728 (Yaratsaga, near Tatsienlu, Szechwan, China). 



Specimens. — Four from Szechwan: Sungpan, 1; Ulongkong (10 

 miles south of Tatsienlu), 1; and Xganyangba, about 60 miles west 

 of Tatsienlu, 2. 



These specimens. differ from gloveri., which is probably their near- 

 est relative, in being grayer and much darker because of more exten- 

 sive black tipping of the hairs. The Sungpan individual is paler with 

 more numerous whitish hairs, but can be called nothing else at 

 present.
