region. In colour great variation is found. The normal 
colour is deep brown to brownish black, with the outer por- 
tions of the longer hairs tipped with light gray, which gives 
the name ‘‘silver-tip.” In some cases the fur is com- 
pletely or partly gray; in others it varies from dark brown 
to cinnamon, and R. H. Chapman, of Washington, D. C., 
recently showed me the skins of a female and two cubs, 
obtained near Revelstoke, B. C., which were of a distinctly 
reddish shade. 
Not only is there great variation in the colour of the skins 
of grizzly bears, but marked differences in the skulls are 
also to be found, and, as a result of these, striking anatom- 
ical differences in the cranial and dental characters. Doc- 
tor C. Hart Merriam, who has kindly demonstrated to me 
these differences in the very extensive series of skulls that 
he has collected, has described a large number of species and 
sub-species within the grizzly-bear group. 
THE BARREN-GROUND GrizzLy Brar (Ursus 
richardsont) 
Throughout the Barren Grounds this species may be 
found, but it does not appear to be anywhere abundant. 
Its occurrence along the Arctic coast was reported by the 
_ early explorers, Samuel Hearne, Franklin, and Richardson. 
It was found in the neighbourhood of the Coppermine River 
and Bathurst Inlet. In J. B. Tyrrell’s explorations in 1900 
evidence of its occurrence on the Thelon was found, and 
J. M. Bell saw, during the same season, these large greyish- 
brown bears quite often along the north and west shores 
of Great Bear Lake. 
In his account of northern mammals MacFarlane states: 
“This bear is not uncommon in the Barren Grounds of the 
Anderson region, nor on the polar shores of Franklin Bay.” 
He recounts a number of instances illustrating the danger-
