1. Stroudsburg, Monroe County.—In 1899 (Ann. Rep. Geol. Surv., Pennsylvania, for 1887, p. 6), Leidy reported the discovery of various fragmentary remains of this species in the Crystal Hill (Hartman’s) Cave, near Stroudsburg. This cave and its contents will be considered on page [310].
2. Riegelsville, Bucks County.—From Durham Cave, situated near Riegelsville, there was sent to the Academy of Natural Sciences of Philadelphia, about 70 years ago, a collection of bones. They were examined by Leidy, who reported on them (Proc. Acad. Nat. Sci. Phila., 1880, p. 349). In this list the elk was not mentioned. In 1889 (Ann. Rep. Geol. Surv. Pennsylvania, 1887, pp. 18, 19), further attention was given to the collection, and the elk was included. The bison, which was mentioned in the first list, was omitted in the second.
