1. Abingdon, Washington County.—In the U. S. National Museum is the outer half of an upper hindermost molar of a horse sent, in 1869, by Mr. Wyndham Robinson. With it were remains of Mammut americanum. The length of the grinding-surface is 30 mm. It belongs pretty certainly to Equus complicatus.

2. Saltville, Smyth County.—Mr. O. A. Peterson (Ann. Carnegie Mus., vol. XI, p. 474) reported the occurrence of an upper left molar of a horse at Saltville. The species has not been determined. The matter will be referred to again on pages [352]–353.

3. Ivanhoe, Wythe County.—In 1869 (Proc. Amer. Philos. Soc., vol. XI, pp. 171–182), Cope gave an account of the discovery of remains of numerous fossil vertebrates somewhere along New River, in the county named. Among these animals were upper and lower milk and permanent molars of a horse. Cope identified these as belonging doubtfully to Equus complicatus. On page [353], the Pleistocene geology of the region and a list of the accompanying vertebrates will be presented.

4. Staunton, Augusta County.—From Dr. W. F. Deekens, surgeon dentist of Staunton, a tooth of a horse found somewhere in that vicinity, was sent to the U. S. National Museum. It had been found in a limestone quarry, 70 feet below the surface, in a narrow stratum of clay. Probably the tooth had been carried down into a crevice in the limestone by a current of water. The length of the grinding-surface is 31 mm. The arrangement of the enamel folds is simple, but the tooth had only just begun to be worn. The narrowness of the tooth is remarkable and it may belong to an unrecognized species.

5. Denniston, Halifax County.—From Mr. G. W. Joyner, living near this place, the U. S. National Museum in 1920 received a left lower grinding-tooth of a horse, found by the donor in a little stream on his farm.
