1. Long Island, James Bay.—In 1898 (Bull. Geol. Soc. Amer., vol. IX, p. 371, fig. 1), Robert Bell reported the discovery of an elephant tooth on Long Island, identified by Boyd Dawkins as that of Elephas columbi; by Cope as probably a variety intermediate between E. columbi and E. primigenius. No measurements were given by Bell, and the tooth was figured obliquely, so its proportions can hardly be determined. Cope regarded it as a hindermost molar, but it appears to be a last milk molar or a first true molar. It is remarkable for the great thickness of the cement between the enamel plates.
The tooth was reported found on the naked rock of an island nearly bare of soil. It might be supposed that a tooth thus exposed would soon have been destroyed by weathering. Lucas (Geol. Surv. Maryland, Pleistocene vol., p. 151) expressed the opinion that it had been carried there by water or ice. One might suppose it had been brought to the island by human agency. Of its geological age nothing can be said, except that it is Pleistocene. This locality is not marked on the map of elephants of undetermined species, as it lies somewhat too far north.
