ric ges and sometimes merely indicated. The profile of the top of 
the head is less rounded than in the Black Bear and the muzzle 
is shorter. The teeth are more massive. 
Distribution. — Merriam, I. c, pp. 74 and 75, gives the distribution 
of the typical Grizzly Bear as " Northern Rocky Mountains from 
Wyoming and northern Utah northward ; also whole of interior 
British Columbia and thence northwestward in the interior to Norton 
Sound, Alaska." Preble states that it occurs in the Rocky Moun- 
tain Range west of the Mackenzie River north to the Arctic Coast. 
Merriam gives the range of the Sonoran Grizzly as "Southern 
Rocky Mountains and outlying peaks and ranges in Colorado, 
New Mexico, Arizona (and probably southern Utah), northern 
Mexico, and southern California. The type locality is the old 
Coppermines, near the Rio Mimbres, in Grant Co., New Mex." 
In Colorado the Grizzly Bear is confined to the more mountainous 
portions of the State, and is apparently not now found in the foot-hills 
at the eastern base of the mountains. It ranges west to the Utah 
Hne.
