Since then the Pao-chi form is distinct from Severtzow’s U. leuconyx, 
which nevertheless does not seem to belong to the genus Ursus, but to 
Spelceus, and since when Heude used the name leuconyx it was already 
preoccupied by a bear at that time placed in the genus Ursus, it cannot 
now be used for the Pao-chi species, although the latter turns out to 
belong to Ursus, while Severtzow’s species seems to belong to Spelceus. 
The Shensi brown-bear (sic) represented solely by the skull from 
Pao-chi in the Sikawei Museum therefore requires a new name, and 
since it has been entirely due to the generosity of my friend, Mr. Robert 
Sterling Clark, that I have been able to carry out my exploration work 
in China, Mongolia, and Manchuria, I have decided to name this 
species in his honor. It may thus be known as: 
11. Ursus dark! nom. nov. 
Selenarctos leuconyx Heude, Mem. cone. THist. Nat. de TEmp. Chin., vol. V, 
p. 2, p.. II, figs. 3, 4, 8, 1898. {nom. preoc.) 
Type: — A skull in the Sikawei Museum, Shanghai. 
Type locality: — Mountains of Pao-chi {i.e. the Tai-pei Shan of the Ching 
Ling Range.), S. W. Shensi. 
In this species the skull is narrow, with rather long muzzle and 
jaws, and a somewhat convex cranial outline. Heude says that the 
paws of his specimen, which is the type, are white; and this is all that 
is known of the color of the species. When I was in this locality I 
made enquiries concerning the form of the bear inhabiting these moun- 
tains, and was told that it was whitish in color with some black about 
it. Later, when hunting in the mountains of the Tai-pei Shan, I 
came across evidences of the existence of bears there, but did not see a 
specimen. The species would seem to represent U. pruinosus in this 
region. 
Habitat Probably the whole, or greater part of the Ching Ling 
Range, up to 11,000 ft. or 12,000 ft. altitude. 
12. Ursus mandchuricus (Heude) 
Ursarctos mandchuricus Heude, Mem. cone. I’Hist. Nat. de TEmp. Chin., vol. 
IV, pp. 23-24, pi. VII, figs. 1-le, 1898. 
Type: — skull in the Sikawei Museum, Shanghai. 
Type locality: — The Ussuri region, near Vladivostock, Manchuria. 
This is a large mainland brown bear that inhabits the forests of 
eastern, central (?), and northern Manchuria. I have seen a number
