gical Society as the skiUl of a Bear said to have como from North 

 America. It is very like the other specimens of U. auierlcanus ; 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 skuU is 11 inches, of the 

 palate 5J inches, of tubercular grinder 1^ inch ; width of zygoma 

 61, of nose 2|, of forehead between the orbits 2/V-

" 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, obliipie, 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 aperture 

 of the nose with an arched front edge. The nasals are broad, ex- 

 tending 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 

 9| inches, of the palate SyV inches, of the tubercidar grinder L| inch ; 

 width at zygoma 6| inches, of nose 2y^ inches, of forehead between 

 the eyes 2| inches.

 different species from the American Bear of the eastern States"

3. MYRMARCTOS. (Ant-Bear.) 

 Head elongate, narrow. Lips moderately extensile. The skull 

 flat above, the nose, forehead, and front of the crown forming a 

 regular shelving line ; brain-case compressed. The nose moderate, 

 flat above, compressed on the sides. The forehead narrow ; the 

 space between the orbits narrower than the nose. The last grinder 

 moderate, longer than the flesh-tooth. Palate deeply concave; the 

 hinder luisal apertuie large, broad ; the sides longer than the width 

 of the front edge. Lower jaw large, elongate.

 The Ant-Bears seem to have been long known, but somehow most 

 unaccountably overlooked. They are evidently very distinct from 

 the carrion or omnivorous Bears ( Ursus).
