58. _Conewango, Cattaraugus County._—In 1908 (60th Ann. Rep. State Mus., p. 60), Clarke reported that part of a mastodon skeleton, consisting of from 40 to 50 bones, mostly vertebræ and foot-bones, had been unearthed in 1906 from the bank of the State ditch along Conewango Creek, close to the boundary between Cattaraugus and Chautauqua Counties. The remains lay on a shelf of hard clay. They were discovered and reported by C. N. Hoard and W. H. Hoard. The locality was probably not far from the town indicated. This animal is to be referred to the last half of the Wisconsin glacial stage; that is, to the Wabash stage. 59. _Buffalo, Erie County._—In 1809 (Phila. Med. and Phys. Jour., vol. II, p. 157), Dr. B. S. Barton reported that a tooth of a mastodon had been found on Buffalo Creek, near its mouth. Of this mastodon one can only say that it lived late in Wisconsin times, not earlier probably than when Lake Iroquois became the immediate predecessor of Lake Ontario. 60. _Jamestown, Chautauqua County._—In 1872 (Amer. Naturalist, vol. VI, p. 178), Mr. T. A. Cheney announced the finding of parts of 2 skeletons of the mastodon, in a swamp about a mile north of Jamestown. One was a small animal, probably a young one, the larger one an adult. Of the latter, 6 teeth in the lower jaw, the tusks, and various other bones were secured. The remains were lying in a soil composed of peat and marl, at a depth of 4 feet. A great mass, 8 or 9 bushels, of broken twigs was found and taken to be the contents of the animal’s stomach. This mastodon belonged to the last half of the Wisconsin glacial stage. 61. _Westfield, Chautauqua County._—Dr. J. M. Clarke, in 1903 (Bull. 69, etc., p. 933), reported the discovery of a part of a skeleton at Westfield. It was on the property of Mrs. Alice Peacock, alongside the Nickel Plate Railroad. A tusk, 6 feet 2 inches long and highly curved, 17 ribs, 8 pelvic and lumbar vertebræ, a patella, and parts of the scapula and pelvis were secured. The bones lay on a pavement of heavy boulders and under several feet of black clayey muck. This animal could have lived here only after the Wisconsin ice-sheet had withdrawn within, or nearly within, the basin of Lake Erie. NEW JERSEY. (Maps 5, 6–A.)
