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, mudh higher than broad ; zygomatic arches 

 regularly convex, more prominent in the middle of their length. 

 Cutting-teeth normal ; the outer in both jaws larger, with a lobe ; 

 the two front upper false grinders small, first smallest ; the hinder 

 upper grinder 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 

 apertures 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. 



The British Museum received, in 1853, three skulls (c, d, e) of the 

 " White Bear of Cashmere " from Lieut. Abbot, belonging to a male 

 and two females. They aU have a rather convex forehead, which is 

 well separated from the nose by a depression in front of the orbits. 

 This depression is much more deep and decided in the females than 

 in the males ; in one it foiras a deep concavity in the middle of the 

 forehead between the orbits. In one female the crown behind the 

 orbits is flat, short, rhombic, broad ; and in the other it is much 

 larger, more oval, and convex. In the male and one female the 

 nose-hole is higher than broad, and in the other female broader and 

 lower. They all have a large elongated upper tubercular grinder.
