Type Xo. Ld.-fOl c? old, University of Iowa .ALiseum, coll('ctc*d on the 
Alackenzie Delta June 28, by Frank Uussell. (AIount(‘d skin with 
skull sei)arate.) 
Characters. Size rather small. Color a curious ])ale dral) brown, 
somewhat darker ou legs and feet; ears conspicuously hairy. Claws 
smooth, moderately to strongly curved ; brownish horn color with paler 
(almost amicer) tips. 
Cranial characters.—>^ku\\ of medium size, al)out equaling old males of 
alascntsis; rather short; lairly broad across zygomata; frontal shicdd 
sloping .strongly upward, moderately sulcate, swollen over orbits hut orbits 
not everted; posterior point of shield rathershort, eudiugahout oue-third 
the distance' from fronto-paiaetal suture to postoi'hital procc'.sses; po.storhital 
])roce.s.se.s pc-g-like, staudiug out nearly horizontally—not deprc'.s.-^ed as in 
alascensis; muzzle rather narrow and high; zygomata slender, the j)os- 
terior roots not expanded vertically; palate liat—not excavated or arched 
as in several species; lower jaw massive, heavier under second and third 
molars than in ala.scen.sis; coronoid blade falcate hut not narrowly so. 
From its neighbor on the east, Ursus richardsoni, to which it may prove 
more lU'arly related than to any other sjiecies, and with the larger specimens 
ot which it agrc'es in size and in certain dental characters, it differs in 
much more highly vaulted cranium ; more highly sloping (less horizontal) 
hraincase; much more elevated frontal region, and very much narrower 
rostrum. 4'h(* frontal shield is much longer than in richardsoni, the 
tmiiiHiral imiiressioiis curving hackwanl to meet one another about }’.^ the 
distance hetwei'n jiostorhital processes and fronto-parii'tal suture, instead 
of tinning abruptly inward; postm’hital jjrocesses more slender than in 
richardsoni ; sagittal crest shorter and less horizontal; iqiper molars very 
much larger, particularly broader. The zygomatic arches are bowed oiit- 
W'ard in both species—not shaiqily angular as in many of the large liears.
