1864.] DR. J. E. GRAY ON THE URSIDA, 693 
The specimens / and J have the opening of the vessel of the palate 
in front of the front edge of the upper tubercular tooth. In a skull 
(z) in the British Museum it is opposite the middle of the tubercular 
on one side, and opposite the front edge on the other. The speci- 
men f is from the western slope of the Rocky Mountains (Lord). 
_ The skull elongate. Nose rather produced, compressed on the 
sides, rounded above; nasal bones long, of the same length as the 
upper part of the maxille, and extending to a line level with the 
middle of the orbits. Forehead convex, rounded, rather shelving on 
the sides. The nose-aperture higher than broad, oblique. Orbits 
small, oblong, longer than high. The zygomatic arch moderately 
strong. The palate rather contracted at the line of the last tooth, 
and more so behind towards the inner nasal opening, which is rather 
narrow, with a transverse front edge, and with the sides considerably 
longer than the width of the front edge. The tubercular grinder 
large, broad, considerably longer than the flesh-tooth. The outer 
cutting-teeth largest, lobed. The front false grinders small, subequal, 
far apart. 
There is an adult skull in the Museum, received from the Zoo- 
logical Society as the skull of a Bear said to have come from North 
America. It is very like the other specimens of U. americanus ; 
but the nasal bones are shorter, and do not extend so far up the 
nose as in the other specimens, stopping nearly a third of an 
inch short of the upper hinder angle of the maxillary bones. The 
palate also is rather more concave. The length of the skull is 11 
inches, of the palate 5? inches, of tubercular grinder 1-4, inch ; width 
of zygoma 64, of nose 23, of forehead between the orbits 2,3,.

* Size equal to or less than that of the Black Bear. Colour varies 
in different shades of brown, very rarely black. Skull broader than 
in the common Black Bear’’ (Baird). : 
The skull of an adult Cinnamon Bear in the Museum agrees with 
the skulls of the other North-American Bears in most particulars ; 
but the orbit is oblong, oblique, much narrower from before back- 
wards than in the common U. americanus, and the tubercular grinders 
longer and broader. The palate is concave, and the hinder aper- 
ture of the nose with an arched front edge. The nasals are broad, 
extending up as far as the maxilla, and in a line with the middle of the 
orbits. ‘The lower jaw is not so high. The length of the skull 
93 inches, of the palate 5,8, inches, of the tubercular grinder 19 
inch; width at zygoma 63 inches, of nose 2;4; inches, of forehead 
between the eyes 23 inches.
