At Zaikof Bay tracks of but one small bear were seen in a 
journey of five miles along the shore line. It is evident that 
there are very few bears on Montague Island, and the small 
extent of vegetation and the limited number of salmon in the 
streams would account for their scarcity. 
Tracks and other evidence of brown bears were seen on 
Hinchinbrook Island and at Port Nell Juan; but bears from 
these localities are probably different from the Montague Island 
form. Hawkins Island is traversed by many old well-worn trails, 
but only one recent track was found there. Apparently this 
island at one time supported more bear than any other, but it 
has recently been depopulated. 
The above determination for the Montague bear is merely 
tentative, awaiting Dr. C. Hart Merriam’s monograph on the 
brown bear group. 
Ursus americanus Pallas. Black Bear. 
One old female was secured by Hasselborg at the mouth of 
Port Nell Juan. This brute was affected by some tooth disease 
which had caused the decay or loss of most of the molars. Black 
‘ 
bear “‘sign’’ was found abundantly about Cordova Inlet and 
less abundantly at the head of Port Nell Juan. Black bear were 
reported by a trustworthy fur dealer as occurring on Hawkins 
Island until within a very recent date. No black bear ‘‘sign”’ 
was noted there however. 
Sorex personatus streatori Merriam. Alaska Masked Shrew. 
A series of 99 specimens secured at eleven localities, five on 
the mainland and six representing islands. This shrew was 
found associated with Sorex obscurus alascensis at all the island 
localities where secured except Chenega and Grafton islands; at 
both of these loealities streatori alone occurred, but not com- 
monly. 
The habits of these two species are apparently identical. 
They were both found most abundantly about the grass flats 
inhabited by Microtus, and were usually taken in traps set on 
the runways of this rodent. On islands where no voles occurred 
shrews were secured in the forest beneath logs and about rock
