8. Ursus isabellinus Horsfield 
Ursus isabellinus Horsfield, Trans. Linn. Soc., vol. XV, p. 322, 1826. 
Ursus arctus isabellinus Hors., Lydekker, P. Z. S. 1897. 
This is the so-called Himalayan snow-bear, or red-bear. It is a 
very pale form, buffy like U. syriacus, from which it differs in having 
the ears very hairy. It is possible that this species belongs more truly 
to the cave bears than to the brown bears, and so should be placed in 
the genus Spelceus. 
9. Ursus pruinosus Blyth 
Ursus pruinosus Blyth, Journ. Asiatic Soc. Bengal, vol. XXII, p. 589, 1858; 
Lydekker, P. Z. S., 1897, p. 426, pi. XXVII (colored). 
Type locality: — Tibetan Himalayas. 
The Himalayan blue-bear, as this species is called, is a small species, 
with long hair of a white and grey above, merging into blackish on the 
legs and feet. A good account of it has been given, together with a 
colored figure, by Lydekker in his paper ‘‘The Blue Bear of Tibet, with 
Notes on the Members of the Ursus arctus Group. P. Z. S., pp. 412- 
426, pi. XXVIII, 1897. 
As already suggested this species, together with our next, may 
prove to be generically, or sub-generically distinct from Ursus. 
10. Ursus lagomyiarius Sev/erzow 
Ursus lagomyiarius Sewerzow, Fauna Turkestan, 1874. 
Ursus lagomyarius, Sew. Przew'alski, Reis. Mongol. I, 1876. — Cat. Zool. Coll, 
of H. M. Przewalski, p. 9, no. 1, 1887, St. Petersburg. 
This appears to be a close relation of Ursus pruinosus, that occurs 
in the highlands of central Asia, northern Tibet and possibly north- 
western China. It is larger than pruinosus, however, and* apparently 
less white in color. 
Another bear belonging to this group, or at least related to it, is 
that named Selenarctos leuconyx by Heude, a skull and paws of which 
were sent to him from Pao-chi in West Shensi. The name leuconyx 
had already been used by Severtzow (= Sewerzow) in naming a bear 
from the Altai (Ursus leuconyx Severtzow, Nachr. Ges. Moscou, VIII, 
1873, p. 79, pi. II.), but there is nothing to show that Heude meant to 
refer the Pao-chi specimen to this species. On the contrary he classed 
it with the Selenarctos, or black bear group, which he had separated 
from Ursus.
