1. Middletown, Monmouth County.—In 1818 (Cuvier’s “Theory of the Earth,” p. 384, plate I, figs. 2, 5), S. L. Mitchill referred to a tooth of an elephant found somewhere about Middletown. In his “Catalogue of Organic Remains,” 1826, page 10, Mitchill mentioned a singular boat-shaped tooth of an elephant, found on Bennett’s farm, Middletown, New Jersey. Both references are to the same tooth; the shape was due to the wear the tooth had suffered. It was said to come from the region where the horse remains were obtained. This tooth was a lower right hindermost molar, much worn. It evidently belonged to Elephas columbi. We have no other information about the specimen. It appears probable that the deposits which yielded remains of horses and of elephants are to be referred to an interglacial stage, at least as old as the Sangamon. The finding of a bone of Megatherium along the New Jersey coast suggests that the Aftonian may be represented there.
