1. Natchez, Adams County.—In Dr. M. W. Dickeson’s account of a collection of bones and teeth made near Natchez (Proc. Acad. Nat. Sci. Phila., 1846, p. 106) he included remains of the genus Bos. To-day these would be referred to the genus Bison.
In 1854 (Smithson. Contrib. Knowl., vol. V, art. III, p. 9, plate II, figs. 2–7), Leidy described and figured bovine teeth from Natchez, which he referred to Bison latifrons. Two of these teeth had been found, as Leidy stated, by M. W. Dickeson, in association with remains of Mastodon (Mammut), Equus, Ursus, Cervus (Odocoileus), Megalonyx, and Mylodon. Three others had been presented by W. H. Huntington, who discovered them in association with remains of Mammut americanum, Equus complicatus, and Felix atrox. Three of the teeth were upper molars, the others, lower molars. Leidy gave the measurements of most of these. The following measurements are those of an upper second and an upper third molar:
| Measurements of bovine teeth, in millimeters. | |||
|---|---|---|---|
| Tooth. | Height. | Length. | Width. |
| Second molar | 67 | 37.5 | 27 |
| Third molar | 75 | 42.5 | 29 |
These teeth are considerably larger than those of Bison bison and B. occidentalis (Geol. Surv. Iowa, vol. XXIII, p. 320).
