Four skunks were taken in the dry hardwood forest of the Cisco Lake Region, one in the same type of habitat near the Little Girl's Point camp, and another in a trap set in the bottom of a muddy ditch in the beaver meadow near Gogebic Lake. An adult male, trapped July 14 in the Cisco Lake Region, was badly infested with tapeworms in the middle part of the small intestine. An adult female, taken July 19, was found to have many tapeworms in the intestine, many nematodes in the lung tissue, an infested liver, and a large number of nematodes in a cavity in the top of the skull. While we were photographing a captive juvenile August 2 at Lindsley Lake a horsefly (identified as _Tabanus atratus_ by J. S. Rogers) burrowed into the fur on the rump of the skunk and began sucking blood. _Taxidea taxus taxus._ Badger. J. E. Marshall reports that he trapped one in the winter of 1889-90 between Gogebic Lake and Lake Superior. _Lutra canadensis canadensis._ Otter. In 1911 J. E. Marshall reported that quite a few remained around Gogebic Lake; he took quite a number in the winter of 1884 and several in the winters of 1889 to 1891. J. E. Fischer took two in Ontonagon County in January, 1921. _Lynx canadensis._ Canada Lynx. J. E. Marshall reports that it was not very plentiful near Gogebic Lake in 1884. He took one in the winter of 1890-91; in 1911 it had almost or entirely disappeared. _Lynx ruffus ruffus._ Bob-cat. J. E. Marshall reports that he took three or four near Gogebic Lake in the winter of 1890-91; in 1891-92 it had become quite numerous; and it continued to increase until 1911 at least. In 1920 residents reported that a few occurred in all the regions visited by us. _Peromyscus maniculatus gracilis._ Deer-mouse. Tall-sedge, 4. Black ash swamp, 5. Arbor-vitae swamp, 11. Black spruce--tamarack bog, 4. Hemlock forest, 16. White pine forest, 5. Wet hardwood forest, 78. Dry hardwood forest, 143. Shrub stage, 19. Paper birch--aspen, 15. Young hardwood forest stage, 2. Edificarian, 6. In the Cisco Lake Region and in the vicinity of Little Girl's Point this species is the most abundant mammal, but in the wet woods at the Gogebic Lake camp it is much less abundant, being exceeded in numbers by the bob-tailed shrew. A total of 308 deer-mice were taken during the summer. It was found in a variety of forest habitats, but it is most abundant in the dry upland woods of the Little Girl's Point Region. The individuals taken in the tall sedges at Mud Lake were probably stragglers from the nearby shrubs and forest, for no deer-mice were taken in the extensive sedges of the large beaver meadow studied near Gogebic Lake. Probably most of those taken in the black spruce bogs were stragglers also, though one individual taken in a large black spruce bog was 50 yards from the nearest deciduous woods.
