1. Rogersville, Hawkins County.—In the U. S. National Museum (No. 520) is a single horse-tooth found many years ago in a crevice in a marble quarry at this place. It is referred by the writer to Equus leidyi (Proc. U. S. Nat. Mus., vol. LVIII, p. 84). With it were sent a canine tooth and a few bones of a peccary, described as Mylohyus setiger (p. [394]).
2. Whitesburg, Hamblen County.—In 1885 Mr. Ira Sayles collected at this place a lot of bones and teeth of vertebrates, described by the present writer (Proc. U. S. Nat. Mus., vol. LVIII, p. 87). Among them is an upper right second premolar of a horse, identified as Equus leidyi. A list of the species will be found on page [395]. E. littoralis also is present.
3. Lookout Mountain, Hamilton County.—In the American Museum of Natural History, New York, is an upper second molar tooth brought from Lookout Mountain (Gidley, Bull. Amer. Mus. Nat. Hist., vol. XIV, p. 121). Under what conditions this tooth was found have not been recorded. It belongs probably to the species Equus littoralis.
4. Nashville, Davidson County.—From William Edward Myer, of Nashville, Tennessee, the writer received, June 26, 1920, some fossils collected near Nashville, about 300 yards upstream from Lock A, in Cumberland River, at a depth of nearly 30 feet beneath a bank of gravel. Below this gravel is a bed of sand apparently 2 or 3 feet thick and this is underlain by another bed of gravel apparently about 2 feet thick. This itself lies on bed-rock at about the level of low water in the river. In the lower gravel were found a lower molar of Equus leidyi, a part of a left femur of a large horse, and an antler of a small undetermined and probably undescribed deer. In the layer of sand were discovered a heel bone of a camel, a part of a tooth of a young mastodon, and some fragments of turtle bones. The equine tooth belongs to the right side. It has a height of about 80 mm., a length of 28 mm. on the grinding-surface, and a width of 16 mm. It is black, and like the others thoroughly fossilized.
The fragment of femur appears to have belonged to a horse perhaps larger than Equus leidyi. It begins at the lower border of the third trochanter and descends to the lower part of the deep fossa for the plantaris muscle. Immediately above the fossa the side-to-side diameter of the bone is 50 mm., the fore-and-aft 60 mm. In a horse of medium size these diameters are respectively 45 mm. and 53 mm.
Later there was discovered at the same locality the upper two-thirds of the right metatarsal. The fragment is 230 mm. long. The upper articular end is somewhat injured; 75 mm. below the upper end the fore-and-aft diameter is 45 mm., the side-to-side diameter 38 mm. The latter diameter was somewhat greater, as the bone appears to be slightly crushed. The specimen is referred to Equus complicatus. Probably the femur mentioned above belonged to this species.

1. Bigbone Lick, Boone County.—In their report published in 1831 (Amer. Jour. Sci., vol. XX, p. 371), Cooper, Smith, and Dekay reported they found in the collection from this place large teeth and bones of a horse. They regarded these as being of equal antiquity with the extinct animals associated with them. In 1847 (Proc. Acad. Nat. Sci. Phila., vol. III, p. 263, 264) Leidy stated that there were in the Academy 10 permanent molars of a horse from Bigbone Lick. These he referred to Equus curvidens. In 1853 (Jour. Acad. Nat. Sci. Phila., vol. VII, p. 263) he wrote that several teeth supposed to have come from this locality had possibly been obtained elsewhere.
