The latter individual was moulting, patches of new fur having replaced the old on the top of the head midway between the ears and eyes, between the shoulders, and on the rump. The other female mentioned above, taken July 30, had nearly completed her moult. Only two specimens have been previously recorded from Michigan, one from Alger County and the other from Chippewa County.[2] _Neosorex palustris palustris._ Marsh Shrew, Water Shrew. Tall-sedge, 1. Ditch-border, 3. September 1 a marsh shrew was trapped in the tall sedges of a beaver meadow near Gogebic Lake, Ontonagon County. Most of the body had been eaten by some carnivore. Other specimens were taken on each of the two succeeding days, and a fourth on September 5. The first specimen taken was trapped eight feet from a tiny stream which flowed through the marshy sedges. Two of the others were taken on the muddy bank of the stream near the water's edge, and the fourth about 35 feet from the water. All were secured within a radius of 35 feet. This species has been recorded but once previously from Michigan, from Chippewa County.[3] _Microsorex hoyi._ Hoy Shrew. Black spruce-tamarack bog, 1. Wet hardwood forest, 1. One specimen was taken July 17 at Fish-hawk Lake in a moderately wet part of the hardwood forest. Another was taken July 29 at the edge of a small black spruce bog. _Blarina brevicauda talpoides._ Bob-tailed Shrew. Tall-sedge, 8. Grassy-meadow, 6. Alder-thicket, 1. Black ash swamp, 6. Arbor-vitae swamp, 4. Black spruce--tamarack bog, 1. Wet hardwood forest, 32. Dry hardwood forest, 8. Shrub stage, 1. Paper birch--aspen stage, 6. The species is rather generally distributed, but is by far the most common in moist woods. In the Cisco Lake Region 11 were secured; in the Little Girl's Point district, 10; and near Gogebic Lake in Ontonagon County, 52. In the latter district it was the most abundant mammal species, even exceeding Peromyscus in numbers; indeed, Peromyscus was relatively uncommon in the partly swampy woods of the region, and it might be that the abundance of the bob-tailed shrews accounts for the scarcity of the deer-mice, for the shrews undoubtedly at times prey upon the mice. The specimen recorded above from the black spruce-tamarack bog was taken near Gogebic Lake in a boggy swamp, which, while dominated by black spruces, yet contained a considerable number of arbor-vitae and hemlocks. In the wet hardwood forest near Gogebic Lake Blarina runways are exceedingly abundant, usually running along or under sticks or logs. Commonly they are just under the leaves, but sometimes for a short distance are without covering. One old log examined was found to be honey-combed with these tunnels. The deeper runways nearly always follow down just under a tree root.
