of the presence of otters during that season. The animals themselves, however, 
were not seen and no attempt was made to trap for them. August 16, 1920, a 
female accompanied by two young was seen in the Isabella River about a mile 
below Isabella Lake; and on August 22, an adult accompanied by one young was 
seen in a beaver pond on a small stream entering Isabella Lake on the northeast 
shore. With continuation of the protection that the otter has enjoyed in the 
region for a number of years past, the species may be expected to show a steady 
increase. 
Mephitis hudsonica. Northern Plains Skunk. — ^My only record is for a female 
specimen taken at the mouth of ^,.small stream entering the North. Kawishiwi 
from the north, just above ‘‘Dead Man’s Rapids,” June 26, 1912. 
Mustela vison vison. Mink. — ^More or less common in all parts of this region. 
In addition to a number of minks seen at various times in other parts of the terri- 
tory, specimens were taken in the following localities: West shore of Lake Bald 
Eagle; the junction of Snake Creek with the Isabella; the upper end of the rapids 
of the Isabella at Bald Eagle; north shore of Lake Isabella. 
Mustela cicognanii cicognanii. Common Weasel.^ — A female of this species 
was taken by one of my companions, Mr. R. C. Chapman, along the Isabella 
River about half a mile above Bald Eagle, August 20, 1912; in August, 1920, I 
saw two of these weasels at the rapids above the locality mentioned. Trapper 
Mayo reported the species as occurring in moderate numbers during the trapping 
season. 
Martes americana americana. Marten. — Mr. R. G. Schreck reports the 
marten as present but very scarce in other portions of northern Lake County 
but in the part visited by me I have no evidence of its occurrence; the twm trap- 
pers mentioned stated that they had not secured any specimens of this species. 
Martes pennant! pennant!. Fisher. — The trappers reported that each had 
taken a number of fishers during the winter of 1919-20, and considered the species 
generally distributed throughout the greater part of this territory. 
Ursus americanus americanus. Black Bear. — ^Fairly common and, I believe, 
increasing. In addition to many signs found in various parts of the region 
visited, bears were seen in the following localities: 1912, northwest shore of 
Gabro Lake; 1913, rapids of the Isabella at Bald Eagle; 1914, North Kawishiwi 
River about a mile east of Farm Lake, and the northwest shore of L. Isabella 
(specimen) ; 1915, Isabella River just below Pike Falls; 1920, Island River at the 
first long rapids above its mouth. 
Sorex personatus personatus. Common Shrew. — A specimen was taken 
August 24, 1914, on a point of land covered with birch, poplar, spruce and balsam 
fir, on the east shore of Lake Isabella. The presence of the shrew was suspected 
in many other localities but the traps employed were rather ill adapted to the 
capture of these tiny mammals and this probably accounts largely for the meager- 
ness of the catch. The species is undoubtedly of general occurrence in all this 
region. 
Sorex richardson!!. Black-backed Shrew. — A single specimen was taken in 
1915, in a bog on the northwest shore of Clear Lake. The species is probably 
of general occurrence.
