very rare in this county, it is seldom seen. We have records for Lodi Township, Ann Arbor, Webster Township, Ypsilanti, and Chelsea. It prefers low, marshy land near the water, and much of its food consists of aquatic insects, which it secures by swimming. It is not as well adapted for burrowing as the preceding species, so it lives in softer soil.

May 8, 1913, a nest containing six half-grown young was found by Kitt Cobb in marshy ground beside the Huron River at Portage Lake. The nest was in a good-sized cavity near the surface of the ground and was lined with dried grass. This species sometimes comes out on the surface of the ground, where I have found several individuals in early spring, most of them dead. February 10, 1907, near Ann Arbor, A. D. Tinker heard one tunneling in the snow and dug it out.

Sorex personatus. Masked Shrew.—In this county the masked shrew is usually found in sphagnum and tamarack bogs. There are records for a tamarack bog, three miles south of Ann Arbor, and for Honey Creek, three miles west of Ann Arbor. I have found it mostly under old logs and in stumps in rather moist situations.

Blarina brevicauda talpoides. Short-tailed Shrew.—Common in swamps, woodlands, and even in meadows, where it has its own runways and also uses those of the meadow mouse, on which it largely feeds.

This shrew is diurnal as well as nocturnal, and I have often seen it in its runways. It is active all winter, and its tunnels may often be seen in the snow. While trapping in Steere's Swamp, south of Ann Arbor, a Synaptomys cooperi in a trap was eaten by one of these shrews, which was later caught in the same trap.

Cryptotis parva. Small Shrew.—The first record for the county was obtained in 1902 at Ann Arbor. In February, 1904, one was found in a barn three miles east of Ann Arbor. At Portage Lake, in 1916, a house cat brought two individuals to her kittens on October 29 and 31, respectively. The specimens taken by me were found in grassy places, usually where briers and shrubs were intermingled with the grass, but not in the woods.

Myotis lucifugus lucifugus. Little Brown Bat.—Almost every winter individuals have been found in the building of the Museum of Zoology, at Ann Arbor, where they have been awakened by the heat long before insects were flying about. Max Peet took one at Ypsilanti June 6, 1904.

Myotis subulatus subulatus. Say Bat.—In 1902 one was found alive in one of the buildings of the University of Michigan at Ann Arbor and was kept in a cage from February 26 to March 6, when it died.

Lasionycteris noctivagans. Silver-haired Bat.—A female which seemed to have an injured wing was picked up at Ann Arbor by A. G. Ruthven, June 13, 1910. It contained two large embryos. This species is rare in this county.

Eptesicus fuscus fuscus. Large Brown Bat.—Common at Ann Arbor and Ypsilanti. It is often found in buildings in winter. We have records for Ann Arbor every month except September, October, and November. Of all the bats this one is the most common about dwellings, and it is the one that most often enters houses at night in search of insects. Perhaps it is attracted by the light, as I have often seen it feeding about the street lights.

Nycteris borealis borealis. Red Bat.—Common at Ann Arbor, and there is one record for Ypsilanti. At Ann Arbor there are records from April 30, in 1919, to July 4, in 1921. Also one was taken in November, 1917. On June 12, 1903, a female with two young attached to the underside was found hanging in a tree in Ann Arbor. The young were naked and blind and quite small. June 10, 1908, another female was found in a similar situation with three half-grown young attached.

Nycteris cinerea. Hoary Bat.—We have records for Ann Arbor, Bridgewater Township, Manchester, and Portage Lake. Our dates run from September 5 to October 15; but in December, 1891, one was found in a barn and was kept alive for several weeks.

Ursus americanus. Black Bear.—Formerly common, and one of the last of the larger animals of the county to be exterminated. The last one known to be in the county was killed in October, 1875, in the big marsh west of Saline. Mr. George Inman, one of the pioneers of Lodi Township, told me that he had seen one just killed a few miles west of Ypsilanti in 1852. One was killed in Pittsfield Township in 1835. Black or brown is the normal color in this state, but I have heard of one albino which was taken in Bay County not many years ago.

Canis lycaon. Timber Wolf.—When the county was first settled the wolves were so destructive that it was difficult to keep any domestic animals. As late as 1840, 30 sheep were killed for a neighbor of my father's in Lodi Township; and another neighbor was himself chased by a pack in the winter of 1836. In October, 1834, a large wolf was seen by Mr. S. P. Allen near Ypsilanti. In looking over the county records I find that in 1837 a bounty of five dollars each was paid to four residents for eight wolf scalps; in 1838 eight more bounties of eight dollars each were paid; and up to 1839 bounties to a total amount of $178 had been paid. The records for the next twelve years are not available, but as late as 1853 two wolf bounties of eight dollars each were paid to residents of the county. Some of these probably refer to coyotes. We have one record of a black wolf for the county.

Canis latrans. Brush Wolf, Coyote.—In the History of Washtenaw County[1] there is a full-page picture of hunting the prairie wolves in an early day, which shows men on horseback in oak openings, rounding up the wolves. In the same volume is an account by Mrs. H. L. Noble, saying that the wolves would "come at evening and stay about the cabin all night, keeping up a serenade that would almost chill the blood in my veins." These were no doubt coyotes. In 1905 I mounted a large male, weighing 45 pounds, which had been shot in Sharon Township, March 10, by Mr. Keeler. Another is reported to have been seen in the same township in 1910.

Vulpes fulva. Red Fox.—The early settlers report the red fox as being quite common and destructive to small lambs, poultry, and game. Owing to its cunning this species has been able to live and increase in spite of much hunting and trapping. It is nocturnal as a rule, though I have seen them often in the daytime catching mice on the marshes. In April, 1883, a den was found in Lodi Township, and by careful watching the young could be seen playing about the entrance to the den while waiting for their mother to bring them food. The young in this den were moved to other dens every week or so, and to my certain knowledge were moved three times before they were dug out by a friend and myself. One transfer was for more than one-third of a mile. There were six of them about the size of small cats. These dens seem to have been woodchuck holes dug out and enlarged. Some were in hillsides, but some were on level ground. The den dug out was an old woodchuck hole. It extended about 25 feet into a bank, with a large nest chamber at the end about six feet from the top of the ground. A second entrance to the tunnel led down from the top of the bank and joined the tunnel about 12 feet from the nest. Some dried grass was noted in the nest chamber. A black fox was
