Ours brun élancé de Pologne, De Blainv. Ostéogr. t. 7 (skull). 
Hab. Europe, Poland. 
Only known from a skull in the Paris Museum. It is very different 
from the other skull trom Poland ; the nose is much more produced ; 
the crown more evenly convex ; the forehead raised more suddenly 
from the nose ; the lower edge of the lower jaw curved, much arched 
up behind. I have not seen it: it may be only an accidental variety. 
2. URSUS ISABELLINUS. Indian White Bear. B.M. 
Fur dirty white or yellowish ; hairs of the back and nape elon- 
gated, very soft, curled, of the sides rigid, adpressed ; claws short, 
straight, and blunt ; forehead of skull convex over the orbits, sepa- 
rated from the nose ; palate flat, rather slender, narrow; the upper 
tubercular grinders long, considerably more than half as long again 
as the flesh-tooth.

The skull rather short. Nose narrowed, compressed, flat at the 
top, with a very large nasal aperture, not so wide as the forehead 
between the orbits. Forehead broad, flat, convex, on a line, at the 
back edge of the orbit, with a concavity in the middle in front of the 
orbit ; the most convex part of the crown over the condyles. Orbit 
oblong, oblique, much higher than broad ; zygomatic arches regu- 
larly convex, more prominent in the middle of their length. Cut- 
ting-teeth normal; the outer in both jaws larger, with a lobe; the 
two front upper false grinders small, first smallest ; the hinder upper 
erinder very large, elongate, much larger than the flesh-tooth. The 
palate flat, moderately broad, suddenly contracted behind, on a line 
rather behind the hinder edge of the last tooth ; inner nasal aper- - 
tures moderate, truncated in front, the sides half as long again as 
the front edge. Lower jaw with a rather large chin and a flat lower 
edge.
