In view of the littoral habitat of this animal and its non- 
insular distribution, we are justified in considering it a very 
recent immigrant into the Alaskan region. 
Canis pambasileus Elliot. Alaska Timber Wolf. 
The skull of a large black specimen was secured from a 
trapper at Cordova Bay. This man, who was also a fur dealer, 
reported black wolves to be as abundant as the normally colored 
individuals. The same proportion between the melanistic and 
the normal coloration apparently holds good at Yakutat and no 
doubt also at the intermediate localities along the coast. Tracks 
were okserved on the river bars at Cordova Bay and at the head 
of Port Nell Juan. 
Lutreola vison melampeplus (Elliot). Kenai Mink. 
A single one secured on Dise Island in a trap set in one of 
the runways. Another was seen by Miss Kelloge on Hinchin- 
brook Island, where tracks were also observéd about the mouths 
of creeks. Well-marked mink trails were found on Knight, 
Dise, and Eleanor islands. These mink trails, sunk two or 
three inches below the surface of the moss and heather which 
forms a dense mat over the ground, skirted the beach at a dis- 
tance of ten yards or less. 
Putorius alascensis Merriam. Alaska Weasel. 
A single specimen, an adult female, shot by Miss Kellogg on 
Hinehinbrook Island. This was taken at timber-line at 1200 
feet altitude in a dense thicket of prostrate mountain hemlock. 
One other individual was observed on a small islet in Port Nell 
Juan running about the rocks at the water’s edge. Numbers 
are trapped on the mainland during the winter. Weasels 
appear to be found only on the mainland and the islands lying 
close to the shore, being absent from the isolated central ones. 
Lutra canadensis (Schreber). Land Otter. 
Four specimens secured on Montague Island, two by Miss 
Alexander at Port Chalmers and two by Dixon at Hanning Bay. 
This is the most widespread species of carnivore in the Sound.
