_Sciurus carolinensis leucotis._ Northeastern gray squirrel. Black squirrels were found in numbers in the early days. _Glaucomys volans volans._ Eastern flying squirrel. Said to be common. A large number were seen by Mr. Schmidt on one old stub in Warren Woods some years ago. Several were seen in 1918 by Mr. Fox in second-growth oak woods in a little ravine about one and one-fourth mile west of Warren Woods. One was caught in Three Oaks in the fall of 1919. _Cervus canadensis canadensis._ American elk. One horn from a large swamp in Berrien County is in the Chamberlain Memorial Museum of Three Oaks. _Odocoileus virginianus borealis._ Northern white-tailed deer. Formerly abundant in the region. Several molars were picked up in Warren Woods. FOSSIL MAMMALS OF BERRIEN COUNTY The records of fossil mammals from Berrien County here published have been collected by George R. Fox, who has also kindly loaned from the collections under his care several specimens for identification. Dr. E. C. Case assisted with the identification of the mammoth teeth. _Mammut americanum._ Mastodon. (1) About 1897 the teeth of a mastodon were dug up by a dredge within the village limits of Eau Claire. Their disposition is unknown. (2) At Snow, in section 36, Lake Township, a tooth was found. This came into the possession of Frank Striker of Buchanan. (3) A portion of a tusk and part of a skull were found on the Beebe Farm near Baroda. These were sent to Washington, D.C. (4) In the excavation of a ditch through a small marsh lying near Bakerstown in Section 3, of Bertrand Township, the dredge uncovered in the distance of between two and three miles bones, teeth, and other evidences of six mastodons. Of these remains the most important was a nearly complete skull with teeth in place and disintegrated parts of the tusks. The skull was secured by Dr. E. H. Crane, who restored parts, the tusks he did not attempt to restore. This skull is now on exhibition at the Ward Museum, Rochester, New York. The skull lay about seven feet deep. It was under a bed of matted oak brush on top of which lay a huge stone slab, estimated to weigh two or three tons. Above was a layer of silt, then gravelly clay; above were more silt beds, three in number. W. Hillis Smith, who helped Dr. Crane secure the skull, furnished the above information. (5) On the Avery marsh, two miles east of Three Oaks, a badly decayed mastodon skull and several teeth were excavated in 1884. Dr. Bonine, Sr., of Niles, assisted at the excavation. The bones and teeth were in the muck about twenty inches below the surface. Other teeth, making seven in all, were found near the same place. Some of the teeth from this locality are on exhibition at the Chamberlain Memorial Museum of Three Oaks. In addition to the above there are several indefinite records of mastodon remains from the county.
