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.
