Low says the polar bear ranges south along the Atlantic 
coast of Labrador occasionally as far as the Strait of Belle 
Isle, and in Hudson Bay to Charleton Island. The species 
seldom goes far inland, except to produce its young. Sorn- 
borger told me that the polar bear is very common and resi- 
dent in northern Labrador. 
Four skulls in Bangs’s collection, all obtained by Sornborger 
of the Eskimo at Hebron and Okak. 
37. Ursus RICHARDSONII Mayne Reid. Barren ground bear. 
Ursus richardsonit Mayne Reid. Bruin: The Great Bear 
Hunt. London, 1860. American Ed., pp. 260, 261. 
1864. 
Although no specimens have ever found their way into col- 
lections, there is no longer any doubt that a huge bear is found 
in the barrens of Labrador. Low says that the Mascaupee 
Indians have many tales of its size and ferocity. I can see 
no reasonable doubt that this bear is true U. richardsonii. 
38. Ursus (EUARCTOS) AMERICANUS SORNBORGERI sub. sp. nov. 
Labrador black bear. 
Type. From Okak, Labrador. Skull No. 7411, young adult 
(probably 2), collection of E. A. and O. Bangs, obtained in the 
summer of 1897 by J. D. Sornborger from the Eskimo. 
Subspecific Characters. The skull differs from that of true 
U. americanus from Maine, Nova Scotia, etc., in being smaller ; 
very much shorter and broader; brain case short and broad; 
zygoma widely spread; frontal region low, broad, and flat, 
with great width across post-orbital processes; nasals short ; 
palate much shorter and broader; molar teeth large. 
External characters unknown.
