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].
