7. _Arcadia, De Soto County._—Dr. Joseph Leidy (Trans. Wagner Free Inst., vol. II, p. 19) stated he had examined 3 crowns of upper molars and fragments of others. In no way did he find them differing from those of the South American tapir, _T. americanus_ (_T. terrestris_). On page 380 will be found a list of the vertebrate fossils found in this vicinity. MISSISSIPPI. (Map 19.) 1. _Natchez, Adams County._—In 1849 (Proc. Acad. Nat. Sci. Phila., vol. IV, p. 182), Dr. Leidy wrote that there was in the collection of the Academy a tooth of a tapir discovered by Dr. M. W. Dickeson near Natchez. It had been found in association with remains of the mastodon and the horse _Equus americanus_ (=_E. complicatus_). The tooth was pronounced a lower molar of the left side, apparently the third milk molar, and was referred to _Tapirus americanus fossilis_; that is, it was looked upon as a fossil tooth of the existing South American tapir. The molar was mentioned by Leidy in 1860 (Holmes’s “Post-Pliocene Fossils of South Carolina,” p. 106). The writer has seen this tooth in the Academy of Natural Sciences at Philadelphia. In 1852 (Proc. Acad. Nat. Sci. Phila., vol. VI, p. 148), Leidy called the attention of the Academy to a fragment of a left lower jaw with 2 teeth of a tapir found in the Pleistocene near Natchez and sent to Leidy by the geologist B. L. C. Wailles. It was referred to _Tapirus haysii_. This specimen was figured and described by Leidy in 1860 (Holmes’s “Post-Pliocene Fossils of South Carolina,” p. 107, plate XVII, figs. 4, 5). Wailles mentioned this jaw in his work (Agric. Geol. Mississippi, 1854, p. 285), and stated that it was found in a ravine on Pine Ridge, which runs through townships 7 and 8, range 3 west, about 6 miles north of Natchez. In a list (furnished by Dr. Joseph Leidy) of fossil mammals found in the Pleistocene of Mississippi, 2 species of tapirs are included, viz, _Tapirus americanus_ (=_T. terrestris_) and _T. haysii_ (Wailles, op. cit., p. 286; Hilgard, Agric. Geol. Mississippi, 1860, p. 196). The associated species will be listed on page 391. TENNESSEE. (Map 19. Figure 23.) 1. _Whitesburg, Hamblen County._—In the U. S. National Museum is a collection of bones and teeth of several species of vertebrates, made in what may once have been the floor of a cave, near the village mentioned. On page 395 will be found a list of the species. Among the remains are 10 teeth, in fine preservation, of a young tapir, described by the writer (Proc. U. S. Nat. Mus., vol. LVIII, p. 88, plate III, figs. 4 to 11), and made the type of a new species, _Tapirus tennesseæ_.
