1. Nashville, Davidson County.—From Mr. W. E. Myer, of Nashville, the writer has received for examination a right calcaneum of an undetermined species of camel, belonging probably to the genus Camelops. This was found near Nashville, in the bank of Cumberland River. At the same locality were found part of a tooth of a young mastodon, a tooth of Equus leidyi, a fragment of a femur of a probably larger horse, an antler of a young deer, a tooth of Mylodon, and some fragments of turtle bones. However, the horse remains and the antler are said to have been lying in a layer of gravel, while the camel and mastodon were in a bed of sand just above the gravel. Over these beds are nearly 30 feet of gravel.

The total length of the calcaneum is 138 mm., the greatest height 67 mm., and the thickness at the rear of the articular surface for the astragalus, 45 mm. From the rear end to the surface for the astragalus is 85 mm. The surface for union with the cuboid is 19 mm. wide, considerably narrower than in the dromedary and in an astragalus from Denver, Colorado, which apparently belongs to Camelops huerfanensis. The outer face of the bone is considerably less concave than in either of the two species referred to. The tuberosity is relatively thicker at the middle of its length than is either of the species mentioned; its height at its middle is relatively less than in the Denver specimen. It is believed that the age of the beds containing these fossils is about that of the Aftonian interglacial.
