TENNESSEE.
1. Memphis, Shelby County.—In 1850, Dr. Jeffries Wyman reported (Proc. Bost. Soc. Nat. Hist., vol. III, p. 281) that a part of a lower jaw of Castoroides had been found at Memphis. With it were a toe-bone of Megalonyx, a tooth of a young mastodon, and a part of the lower jaw of a beaver. It was thought that these remains had been buried in the deposits laid down by Mississippi River. It is to be regretted that the locality and the height above the river were not more exactly specified. The specimen of Castoroides, a right ramus of the lower jaw, is now in the Academy of Natural Sciences of Philadelphia.
