Residents reported it common in all the districts visited by us. We saw signs and tracks in several habitats; and residents saw a wolf in the dry hardwood forest near our camp in the Little Girl's Point district. _Canis latrans._ Coyote. J. E. Fischer reported in 1920 that coyotes had appeared and become numerous in the region at the north end of Lake Gogebic within the last few years. We have secured several skulls and skeletons taken by him in 1920-21. _Vulpes fulva._ Red Fox. Mountain-heath, signs. Signs of fox were found in late August in a narrow growth of heath at the top of a cliff about a mile north of Lake Gogebic Station. J. E. Fischer has sent us a fox taken in January, 1921, in Gogebic County near Gogebic Lake. Benjamin J. Twombley reports that a few occur in the Cisco Lake Region. J. E. Marshall, in 1911, reported that a few occurred around Gogebic Lake. _Urocyon cinereoargenteus._ Gray Fox. J. E. Marshall reported in 1911 that it was rare, but that he had trapped two near Gogebic Lake. _Martes americanus americanus._ Marten. J. E. Marshall reported in 1911 that it was getting scarce in Gogebic and Ontonagon counties. He trapped a number near Gogebic Lake in the winter of 1884-1885, and took 15 in the winter of 1889-90. In 1920 J. E. Fischer reported marten rare near Gogebic Lake. _Martes pennantii pennantii._ Fisher. In 1911 J. E. Marshall reported that it was getting scarce near Gogebic Lake; he trapped four in the winter of 1889-90 and two in 1890-91. J. E. Fischer took one in Ontonagon County near Gogebic Lake in the winter of 1919-20. Ole Petersen in 1911 reported it rare near Gogebic Lake. _Mustela cicognanii cicognanii._ Bonaparte Weasel. Black spruce--tamarack bog, 1. Dry hardwood forest, 4. Trappers report it common throughout the areas visited. We took five specimens near Little Girl's Point. Several specimens taken in the Cisco Lake Region during the winter of 1920-21 were presented to us by Benjamin J. Twombley, and J. E. Fischer sent us a specimen taken in December, 1920, near Gogebic Lake. _Mustela vison letifera._ Mink. Forest--shore, 6. Wet hardwood forest, den. Reported by trappers as common throughout the area studied. In the Cisco Lake Region two were trapped at the water's edge beside a growth of paper birch saplings; and another was shot as it was running along the bank of the Ontonagon River at the edge of a stand of hemlocks. Three others were seen swimming near the latter locality July 29. Upon the approach of the canoe they swam rapidly to an old hollow log in wet hardwood forest on shore. Around and through the log well-worn runways showed evidence of the presence of a den. _Mephitis hudsonica._ Skunk. Ditch-border, 1. Dry hardwood forest, 5.
