The uterus of a female taken July 10, at Fish-hawk Lake, showed a few small swellings which were identified in the field as embryos. Unfortunately, the uterus was not preserved. No embryos were found in 26 other females taken between July 15 and September 4. In the latter part of the season fewer immature specimens were taken than earlier in the summer. These facts show that in this region the species breeds in the spring or early summer and does not usually breed again during July and August. _Myotis lucifugus lucifugus._ Little Brown Bat. Aerial, 15. Nine individuals were shot while they were flying over the lakes in the Cisco Lake Region. These were taken between 8:00 and 9:00 p. m. from July 1 to August 2; but on moonlight nights bats, believed to be of this species, were seen flying as late as 10:00 p. m. At the camp near Little Girl's Point one was shot at 7:55 p. m., August 11, as it flew about over the road through the dry hardwood forest. Five others were shot at the Gogebic Lake camp as they flitted through an opening in the wet hardwood forest. These were taken between 7:30 and 7:55 p. m., August 23 to September 2; but bats almost certainly of this species appeared regularly in the evenings about 7:10 p. m. _Lasionycteris noctivagans._ Silver-haired Bat. Aerial, 3. Near the Little Girl's Point camp one was shot at 7:50 p. m., August 9, and two more in the same region about 7:45 p. m., August 17. One was flying along a road through the dry hardwood forest at a height about equal to that of the tree-tops, and the others were taken in a small clearing in the same forest. _Nycteris borealis borealis._ Red Bat. Aerial, 2. Two were secured near the Little Girl's Point camp at about 7:45 p. m., one August 9 and the other August 14, as they flew about over the road through the dry hardwood forest. _Nycteris cinerea._ Hoary Bat. Aerial, 1. The only specimen secured was shot at 7:55 p. m., August 9, while it was flying over the road through the dry hardwood forest near Little Girl's Point. _Ursus americanus americanus._ Black Bear. Wet hardwood forest, 1. Dry hardwood forest, 1. Reported by residents as being rather common. July 10 a large black bear was seen to cross the railroad track and enter the hardwood forest not over a quarter-mile from Cisco Lake Station. Tracks of a large individual were seen in the mud bordering a small brook in maple-birch-hemlock forest about three miles southeast of the station July 17 and August 15. At dusk, August 28, while Mr. Sherman was setting up a camera and flashgun along a deer trail about 100 yards from the camp on Gogebic Lake, a small bear passed within twenty-five paces of him, apparently but little concerned with his presence or that of the nearby camp and fire, except that it sniffed the air occasionally. _Canis lycaon._ Timber Wolf. Mud-flat, signs. Tall-sedge, tracks. Dry hardwood forest, reported.
