0. Danis. 

 " Fur shaggy, front claws much longer than the hinder, broadly 

 depressed, whitish; palate narrow and contracted behind; ears small. 

 Hind foot elongate." 



470. horribilis. {Crsia), Ord, Guthr. Geog., 2nd Am. ed., 11, 1815, 

 pp. 291, 299, 300. 



Type locality. Montana. 



Geogr. Distr. Rocky Mountains north of Wyoming and Utah; 

 British Columbia to Alaska. 



Genl. Char. Size large; fore claws very long and straight; whit- 

 ish. Skull: frontal region elevated above orbits highest behind post- 

 orbital processes, concealing sagittal crest. 



Color. Usually brownish yellow with a blackish dorsal stripe; 

 mane reddish brown, darkest near tips of hairs, which are brownish 

 yellow or brown; legs generally black or blackish brown. 



Measurements. Skull: total length, 380; end of intermaxillary 

 to end of condyle, 262; greatest width, 235; between orbits, 86.

Genl. Char. "Compared with Rocky Mountain Grizzly it is 

 somewhat larger, the frontal region is furrowed antero-posteriorly 

 between the orbits, the palate averages longer, and the blade of the 

 coronoid process of the mandible is narrower; the first lower molar is 

 broader posteriorly and is much more abruptly and deeply narrowed 

 on the outer side immediately in front of the posterior cusp. Except 

 in a single skull (an old male from the Shaktolik River, No. 76,470), 

 the combined length of the basioccipital and basisphenoid along the 

 median line is decidedly less than half the length of the palate. In 

 the Rocky Mountain Grizzly the occipito-sphenoid length is 

 decidedly greater than half the length of the palate." (Merriam.)
