1. Stroudsburg, Monroe County.—In 1889, Dr. Joseph Leidy reported (Ann. Rep. Geol. Surv. Pennsylvania, 1887, p. 14, plate II, figs. 7–20) the discovery of teeth of Castoroides ohioensis in Hartman’s (or Crystal Hill) Cave, about 3 miles southwest of Stroudsburg and 5 miles from Delaware Water Gap. Its elevation is about 800 feet above the level of Delaware River. The species associated with this giant beaver will be listed on page [309]. The parts figured by Leidy are a portion of a palate, with the molars and some of the premolars, and both rami of the lower jaw, showing the three temporary molars and the first true molars, with some incisors and the permanent canines.
