NEW JERSEY.

1. Swedesboro, Gloucester County.—In 1868 (Cook’s Geol. New Jersey, p. 741), Cope stated that Equus complicatus was represented in New Jersey by a series of teeth obtained while a mill-dam at Swedesboro was being cleared. No further information has been secured. At the Academy of Natural Sciences of Philadelphia, the writer has seen a horse-tooth labeled as coming from the town named; but whether or not it is one of those referred to by Cope it is impossible to say.
2. Fish House, Camden, Camden County.—In 1869 (Trans. Amer. Philos. Soc., vol. XIV, p. 250, fig. 55), Cope wrote that a partial skull of Equus fraternus had been found at Fish House in a blackish clay at a depth of 20 feet from the top of the clay. Over the clay was imposed a bed of sand from 8 to 15 feet thick. This important skull appears to have been lost (fig. 7).
In 1897 (Ann. Rep. Geol. Surv. New Jersey for 1896, p. 208, plate X), Lewis Woolman described other remains of horses supposed to belong to Equus complicatus, secured in the same Fish House clays. The writer has seen these and regards them as belonging to the species just named. These remains of horses will be mentioned on pages [302]–[303].
3. Navesink Hills, Monmouth County.—Somewhere in the northeastern part of Monmouth County, in the region of the Navesink (or Neversink) Hills, have been found remains of a fossil horse. They were first mentioned by S. L. Mitchill (Cat. Organ. Remains, 1826, pp. 7, 8). He mentioned a cervical vertebra and teeth in sound condition. Leidy (Jour. Acad. Nat. Sci., Phila., vol. VII, p. 261) wrote that a vertebra and teeth were associated with remains of a mastodon. Mitchill mentions only a part of a tibia of a mastodon. These objects were all presented by Mitchill to the Lyceum of Natural History in New York. The writer believes these teeth had been buried in an early Pleistocene deposit.
