the two previous forms. It is probably not typical but seems to 

 be nearer fygargus than anything else that has been described. 



Genus HYDROPOTES Swinhoe 



HYDROPOTES INERMIS INERMIS Swinhoe 



Eydropotes inermis Swinhoe, Proc. Zool. Soc. Londou, 1870, p. 89 (Cbinki- 

 aug, Kiangsu, China). 



Specimens. — Thirteen : Yochow, Hunan, 10 ; Anhwei, 1 ; Soochow, 1, 

 and Chinkiang, Kiangsu, 1. 



This fine series shows that there is much individual variation in 

 color, and in size of skull, within this genus. 



HYDROPOTES INERMIS ARGYROPUS Hilzhcimer 



Eyrdopotes argyropus HiLZHEaMER, Abliand. Mus. Naturk., Madgeburg, vol. 

 1, 1906, p. 171 (Korea). 



Speeiinens. — Eleven: from Korea, 5 odd skulls and 4 odd skins, 

 and 2 from north China or Manchuria. 



Heude was the originator of this racial name but his use of it 

 constituted a nomen nudum and Hilzheimer seems to be the one who 

 should be credited with its accej)table use. The form is recognized 

 on the basis of average darker and richer coloration, with more 

 reddish about the head. The skull exhibits no consistent differences. 

 The disposal of the two skins from uncertain localities is a question, 

 and they are allocated provisionally. They are in extremely heavy, 

 pale, winter pelage and are very different from any of the others, 

 which may be due entirely to season. 



Family BOVIDAE 

 Genus OVIS Linnaeus 



OVIS AMMON AMMON (Linnaeus) 



Capra ammon Linnaeus, Sj^st. Nat., ed. 12, vol. 1, 1766, p. 97 (Upper Irtiseh 

 River, Siberia). 



SpecimeTis. — Four, from near Tchegan-Burgazi Pass, Mongolia. 



These skins were purchased in Kosh-Agatch. Two are in pale 

 gray and very short summer coat and two in heavy winter pelage. 

 One of these is rather light and the other very dark indeed, with a 

 middorsal stripe that becomes perfectly white below the withers. I 

 can hardly believe that these two are of the same subspecies but as 

 one cannot be certain where they were secured they must both be 

 placed under this race for the present.
