6. Lepus sp. Hare. 



A hare, No. 4,600, whose characters indicate a near approach to 

 maturity, evidently belongs to a species about the size of Lepus 

 americanus. It was taken on the east slope of the Khin Gan Mts., 

 in Mongolia, at an elevation of about 4,000 feet. It is much smaller 

 than any hare described from this region by Radde, Schrenck, 

 Pallas and others, the hiud foot measuring only 105 mm. in length. 

 The tail and ears are relatively long, the former black above and 

 white below. The ears are blackish-gray and ochraceous, like upper 

 head and body, and bordered at tips with black. The belly, breast, 

 vent and chin are pure white to bases of hairs; the lower neck, fore 

 legs, and space between shoulders are tawny ochraceous. The skull 

 characters show close affinity to Lepus americanus. It was taken 

 July 15th, and is in full summer pelage. 



7. Gazella gutturosa mongolica (Heude). Mongolian Gazelle. 



An adult male and a yearling of the same sex, of the " Imperial 

 Sheep " or " Houang Yangtze " are represented by two heads in the 

 collection. On the supposition that Heude's species mongolica' 

 is separable from the Siberian gutturosa of Pallas, I adopt the above 

 trinomial. Its separability from what Heude figures as hillieriana 

 on the next plate I am inclined to doubt. In the yearling the horns 

 are about 3 inches long and curve inward, their points touching 

 and slightly overlapping above the occiput. The specimens were 

 taken in the Imperial Hunting Park northeast of Dolonnor. A 

 female of the same species, shot June 6th, contained a nearly mature 

 foetus. 



8. Capreolus pygargus (Pallas), subsp.? Mongolian Roe Deer. 



The skull and scalp of a fine male specimen of this animal were 

 secured in the Imperial Hunting Park. It is placed in the above 

 category on the authority of Sir V. Brooke 8 who considers the Man- 

 churian Roe to be at least a small race of pygargus. 



It is remarkable that this specimen, shot in the middle of June, is 

 possessed of a fine set of antlers from which the velvet has not wholly 

 disappeared around the bur. 



9. Lynx isabellinus (Blyth). Thibetan Lynx. 



A fine adult specimen of Lynx, No. 4,603, also taken in the Im- 

 perial Hunting Park, agrees with Blyth's description of isabellinus
