In the National Museum is a finely preserved upper right third or fourth premolar of what appears to be _Equus complicatus_ which is recorded having been found in Wando River, northwest from Charleston. The tooth is 75 mm. high, 31 mm. long on the grinding-face, and 27 mm. wide. The enamel is much complicated. In Holmes’s “Post-Pleiocene Fossils of South Carolina,” on pages 102 and 104, Leidy mentions an upper second premolar of _Equus fraternus_ found on Goose Creek, about 12 miles from Charleston. He added a paragraph on the geology. Further reference to this will be found on page 363. In the Charleston Museum and in the private collections about Charleston the writer has seen many teeth of horses found in that region, most of them without statements about exact localities, though some were found in Stono River. The teeth of _E. leidyi_ appear to be more numerous in the collections than those of _E. complicatus_. Many teeth of both species are contained in the Scanlan collection, made in the region about Charleston and now owned by Yale University. In this collection are found also two lower molars which the writer refers to _Equus littoralis_. The reader is referred to pages 362 to 366. 3. _Richland County._—On the occasion referred to in the next paragraph, Robert W. Gibbes presented a tooth of a horse found in Richland district at a depth of 17 feet, in a slough, supposed to have been a former bed of Congaree River. 4. _Darlington, Darlington County._—In 1850 (Proc. Amer. Assoc. Adv. Sci., vol. III, p. 67), Gibbes showed before the Association several specimens of horse-teeth, referred to _Equus americanus_ (_E. complicatus_), found in supposed Pliocene at Darlington. They were reported as having been discovered associated with bones of a mastodon, presumably of _Mammut americanum_. No additional information was furnished. Darlington is situated on a branch of Black Creek, an affluent of Great Pedee River. The teeth were probably found in a Pleistocene terrace deposit. GEORGIA. (Map 17.) Apparently remains of extinct horses have been found in Georgia in only two places, as follows: 1. _Brunswick, Glynn County._—During the construction (in 1838–39) of a canal which connected Altamaha and Turtle Rivers, remains of various fossil vertebrates were discovered. A list of these will be given on page 370. Among the remains was a lower left last premolar or first molar of an extinct horse, described by Leidy in 1847 (Proc. Acad. Nat. Sci. Phila., 1847, p. 266) and again in 1860 (Holmes’s Post-Pleiocene Foss. South Carolina, p. 104, plate XVI, fig. 23). In the first publication he referred the tooth to his species _Equus americanus_ (=_E. complicatus_); but in 1860 he referred it to his _Equus fraternus_ (=_E. leidyi_). The size of the tooth appears to justify his later conclusion.
