11. Peace Creek, De Soto County.—In the U. S. National Museum (No. 1990) is an upper right hindermost molar recorded as having been found on Peace River. It was a part of the exhibit of the Plant System at the Centennial Exposition at Atlanta, Georgia. It is credited also to the Peace River Phosphate Company. Probably the tooth was found somewhere not far from Arcadia. Leidy (Bull. 84, U. S. Geol. Surv., p. 129) does not record the species from Arcadia, but his undetermined species of the genus may have been M. americanum.
The tooth mentioned above has five cross-crests and a conical talon. At the ends of the transverse valleys are large tubercles.

1. Bogue Chitto, Dallas County.—The U. S. National Museum contains 3 or 4 fragments of large molars of Mammut americanum found not far from the town named. One fragment is labeled as having been found in section 10, township 17 north, range 7 east. This would probably be 6 or 7 miles west of north from the town named. Another fragment is said to have been found in the bed of Bogue Chitto. The teeth were sent to the U. S. Geological Survey by Crawford P. Lewis. From this same region there have been collected remains of Elephas imperator and Equus leidyi.

1. Perthshire, Bolivar County.—In the U. S. National Museum is a fragment, the rear end, of an upper left hindermost molar of Mammut americanum, received from Perthshire in August 1914. It is the gift of Mr. S. D. Knowlton and was reported as having been sucked up with gravel from the bed of Mississippi River. This place is in the northern part of Bolivar County and immediately south of latitude 34°.
2. Caseilla, Tallahatchie County.—The writer has seen a lower left last molar of a mastodon, found in 1915, near this place. It was sent to the U. S. National Museum for identification by Dr. B. Franklin, of Caseilla. He stated that the tooth had been found in Avant Creek, about 3 miles above its entrance into Yalobusha River, apparently in the southeastern corner of Tallahatchie County, in township 23 north, range 7 west. The tooth had been buried in joint clay. The banks of the creek are usually about 10 feet high, but where the tooth was found, on the south side of the creek, the bluff is about 50 feet high.
3. Jackson, Hinds County.—In the collection of the Academy of Natural Sciences of Philadelphia is a lower left last milk molar, presented by Dr. Isaac Lea and reported to have been found near Jackson, Mississippi. No additional information was furnished. The tooth is but slightly worn and has complete roots.
