James Hall, in 1843 (Geol. 4th Dist., p. 364), reported that in the town of Perinton there had been found in the bank of a small stream, in gravel and sand, a tusk and several teeth. This place appears to be, or to have been, very near Pittsford. At Perinton, too, was found a tooth of the elephant _Elephas primigenius_, as mentioned on another page. It was near here probably that there were found parts of two skeletons of the peccary _Platygonus compressus_, as noted in its proper place. Inasmuch as all these animals, as well as those found nearer Rochester, were buried in deposits overlying Wisconsin drift, they must have lived after the withdrawal of the ice beyond Rochester, and at a time when the region had taken the present aspect or nearly so. 43. _Rochester, Monroe County._—In 1842 (Nat. Hist. N. Y. Mamm., p. 103), J. E. De Kay stated that in 1817 remains of mastodon had been found in Rochester, 4 feet below the surface, in a hollow or water-course. He did not give his authority for this statement. James Hall, in 1843 (Geol. 4th Dist., p. 364), reported that in 1838, during the excavation of the Genesee Valley Canal, at its junction with Sophia street, various bones of a mastodon had been discovered. They are said to have been intermingled with gravel and covered by clay and loam, above which was a deposit of shell marl. The bones were placed in the State Museum at Albany. C. D. (Amer. Jour. Sci., vol. XXXIII, 1837, p. 201) says that these bones were lying on and in a hard body of blue clay and about 2 feet above the limestone, which itself was polished. Clarke (Bull. 69, New York State Mus., p. 931) reported, on the authority of H. L. Ward, that a few remains of mastodon had been found at Mount Hope cemetery. In the collection of the University of Rochester is a proboscidean rib 837 mm. long, which is labeled as having been found January 27, 1913, at the corner of Charlotte boulevard and Miller street. It lay in gravel 12 feet below the surface. It seems to the writer to belong to _Mammut americanum_. 44. _Scottsburg, Livingston County._—Clarke (Bull. 69, etc., p. 932) reported that 20 bones and various fragments of bones of a mastodon had been collected here by F. H. Bradley and H. A. Green, and presented to the Yale collection by R. S. Fellows. No additional information was furnished. These remains include a hindermost lower molar (Cat. No. 11714) that had not yet come into use. The animal may be supposed to have lived during or after the last half of the Wisconsin stage. 45. _Fowlerville, Livingston County._—Dr. John M. Clarke (Bull. 69, etc., p. 932) stated, on the authority of Mr. H. J. Peck, that 3 or 4 teeth, tusks, and other bones, badly broken, had been found, in 1886, in an excavation on the bank of Genesee River, 80 feet above the water. No further information has been recorded.
