1. Stroudsburg, Monroe County.—In Crystal Hill (Hartman’s) Cave, near Stroudsburg, there was found, many years ago, bones and teeth of what Leidy (Proc. Acad. Nat. Sci. Phila., 1880, p. 347) called Rangifer caribou. In 1889 (Ann. Rep. Geol. Surv. Pennsylvania for 1887, p. 5) the remains are spoken of as fragments of jaws and teeth.

2. Riegelsville, Bucks County.—In his earliest mention of remains found in Durham Cave, near Riegelsville, Leidy included the woodland caribou (Rangifer caribou). In his list published in 1889 (Ann. Rep. Geol. Surv. Pennsylvania for 1887, p. 18) this species is not included, but the writer does not know why it was not.
