Another tooth, either a last milk molar or a first true molar, is not worn to the base and retains the front root. There are 12 plates and a large talon and a 100–mm. line crosses 8 plates. The enamel is thick and considerably festooned. The greatest length of the tooth is 173 mm. There is another lower right tooth, probably the last milk molar, which presents 11 plates and front and rear talons. There are nearly 8 plates in a 100–mm. line.
Another right lower tooth, apparently the first true molar, 165 mm. long on the grinding-face, has likewise 8 plates in 100 mm. A part of an upper hindermost molar preserves 11 plates. There are 6 plates in 100 mm. and the enamel is thick and folded.

4. _Head of Cooper River, Berkeley County._—In 1802, John Drayton (“A View of South Carolina,” p. 40, plate, fig. 5) wrote that elephant bones had been discovered in the excavation of a canal joining Santee and Cooper Rivers. Drayton’s illustration shows that this tooth must have belonged to _Elephas columbi_. The locality was in Biggin Swamp, apparently not far from Monks Corner. At the same time and place were found remains of _Mammut americanum_. The materials are said to have been deposited in the Charleston Library. Barton (Archæologia Amer., p. 22) stated he had examined teeth of both the mastodon and the elephant from this place. Richard Harlan (Jour. Acad. Nat. Sci. Phila., ser. 1, vol. III, p. 66, plate V, fig. 3; Med. Phys. Res. p. 359, plate, fig. 3) stated that a tooth of an elephant from the Santee Canal had been sent to the Academy at Philadelphia.
1. _Brunswick, Glynn County._—This is the type locality of _Elephas columbi_. This species was based by Falconer (Quart. Jour. Geol. Soc. Lond., XIII, 1857, table opposite p. 219) on a part of a tooth received from the geologist Charles Lyell and which had been found in the Brunswick Canal. The specimen consisted of 10 median plates of a lower second or third molar. Falconer figured it in 1868 (Palæont. Mem., vol. II, pp. 214, 221, plate X). Lyell (Second Visit, etc. vol. I, p. 348) noted that an elephant had been found in excavating the canal. Richard Harlan, in 1842 (Proc. Acad. Nat. Sci. Phila., vol. I, p. 189), stated that a large collection of bones of various animals had been presented to the Academy by J. Hamilton Couper, of Darien, Georgia. Among these were teeth of _E. primigenius_. Couper, in 1848 (Hodgson’s Memoir, etc., p. 45), stated that two lower jawbones with teeth, several loose teeth, two tusks, and several vertebræ of _Elephas primigenius_ had been collected in the canal during 1838 and 1839. These remains quite certainly belonged to _Elephas columbi_ unless possibly some belonged to _E. imperator_.
