JOUENAL OF MAMMALOGY 
as far as is at present known are brown, light buffy-brown, grayish, or 
whitish in their pelages. There is usually no sign of a white crescentic 
collar, except sometimes in the very young cubs. The soles of the feet 
have the plantar and carpal pads cleft across in the hind feet, some- 
times with, sometimes without hair in the cleft; while the digital pads 
are separate. In the forefeet the plantar and carpal pads are sepa- 
rated, the former being reduced to a small round knob. The feet are 
thus very distinct from those of Selenarctos. 
The group was represented amongst the skulls I had for comparison 
by No. 1, labelled leuconyx from Pao-chi, Shensi, No. 6, the one from 
Vladivostok (mandchuricus) , and No. 7, the one from the Bering region 
called heringianus. 
As regards the name Ursarctos, it was applied by Heude to the 
Vladivastok brown bear, mandchuricus, and to the Bering skull, the 
locality of the latter being very vague. Since neither of these can be 
separated generically, or even subgenerically from true Ursus, the name 
Ursarctos cannot be used. 
It is in the genus Ursus that the greatest confusion seems to reign, 
due largely to lack of sufficient material from properly identified local- 
ities, and to the close connection between this genus and our next, 
Spelceus. 
As regards the bears of eastern Asia the following species may for 
the present be included in the genus Ursus: — (1) Ursus collaris Cuvier, 
of Siberia, (2) U. isahellinus Horsfield, of the Himalayas, (3) U. prui- 
nosus, Blythj of the Himalayas, (4) U. lagomyiarius Sewerzow, of 
central Asia and north-western China, (5) U, heringianus Middendorff, 
of Great Shantar Island, (6) U. mandchuricus Heude, of Manchuria 
and the Amur, and (7) U, yesoensis Lydekker, of Yezo or Hakodate. 
Of these it is possible that U, pruinosus and U. lagomyiarius may be 
found to be subgenerically, or even generically distinct from Ursus, 
and possibly more closely allied to Spelceus; but until more material 
from all parts can be gathered for comparative purposes this cannot be 
determined. 
7. Ursus collaris Cuvier 
Ursus collaris Cuvier, Hist. Nat. Mamm., livr. XLHI, 1824. 
This apparently is the brown bear of the true Ursus group that in- 
habits Siberia. Trouessart gives its range as the Ural Mountains, 
Siberia, Batang, and Tengri-Nor. It is generally supposed to range 
into Kamschatka, but this is open to doubt. It is rather a fight brown, 
with dark brown rings round the eyes.
