1. Pittston, Luzerne County.—In 1873 (Contrib. Ext. Fauna West. Terrs., p. 255, plate XXVIII, fig. 8), Leidy described and figured a tooth as that of Bison latifrons. This has been referred here to an undetermined species of Symbos. In a paper on the distribution of the American bison in Pennsylvania, Mr. S. N. Rhoads (Proc. Acad. Nat. Sci. Phila., 1895, p. 245) concluded that this tooth belonged to the existing bison. He stated also that the Academy had two other teeth, lower molars, from the same place, which Leidy had labeled as “Bison americanus” and regarded as more recent than the figured tooth. Rhoads thought the identification correct, but that they belonged to the same individual as did the tooth figured by Leidy. The writer has not seen these lower teeth and admits them here only provisionally. They were found along Susquehanna River, in association with remains of Mammut americanum and Equus complicatus? (“E. major”). If any of the bovine teeth belong to Bison the species belonged to early or middle Pleistocene and is now extinct.
2. Port Kennedy, Montgomery County.—The presence of Bison in the famous cave at this place was announced by Wheatley in 1871 (Amer. Jour. Sci., ser. 3, vol. I, p. 384). Cope, in his account of 1899 (Jour. Acad. Nat. Sci. Phila., vol. XI), does not mention the genus; but Mercer, on page 280 of the same volume, credits Wheatley with having found remains of three individuals of one undetermined species. He used the generic name Bos.
A description of the Port Kennedy Cave and its contents and remarks on the geological age of the fossils will be given on pages [311] to [320].

1. Fincastle, Brown County.—In 1887 (Jour. Cin. Soc. Nat. Hist., vol. X, p. 20), Horace P. Smith, curator of the society, described a fine pair of horn-cores of Bison latifrons found in Brown County and which had come into the possession of the society. They were discovered at a depth of 18 feet, in making excavations for the piers of a bridge across Brush Creek. Inasmuch as nearly the whole of the course of this stream is in Adams County, the locality must have been in the northeastern corner of Brown County, near Fincastle, where the creek has its source, and within the area of the Illinoian drift. Smith thought that the horn-cores were in the drift; but, if so, the overlying materials must have been washed down over them after their burial. It is improbable that they were ever beneath or in the glacier. The animal probably lived during the Sangamon interglacial stage; quite certainly before the Wisconsin.
2. North Fairfield, Huron County.—In the Norwalk Museum, at Norwalk, are some skull-bones of a bison found at some point not known to the writer, about 7 miles from North Fairfield, while search was being made for bones of the megalonyx which belongs partly to the museum at Norwalk, partly to the Niver family at North Fairfield. These bison bones served as the type of Bison sylvestris, described by the writer in 1915 (Proc. U. S. Nat. Museum, vol. XLVIII, p. 515, plate XXX). This is the only species of extinct bison known that lived after the close of the Wisconsin stage.
