1. Rogersville, Greene County.—The writer has received from Mr. Andrew Waychoff, of Waynesburg, a small photograph of a lower hindermost molar, found 3 miles south of Rogersville, in the bed of Hargus Creek. The tooth was found about 1909 or 1910 and passed into the possession of Mr. Waychoff; but it had been broken by the finder, who wished to see what was in it. The tooth has 8 ridge-plates in a 100–mm. line and the form and arrangement of the plates indicate that it belonged to Elephas columbi. It is impossible to determine, with the knowledge at command, the stage of the Pleistocene to which this animal is to be assigned.
2. Pittsburgh, Allegheny County.—In 1910 (Science, n. s., vol. XXXI, p. 31), an anonymous note stated that there was in Carnegie Museum of Natural History an enormous tusk, supposed to be of this species, found in the banks of the Allegheny River, in a suburb of Pittsburgh. There is, however, no certainty that the tusk was not that of E. primigenius or of Mammut americanum. In either case it would be difficult to refer the animal to any definite Pleistocene stage.
3. Tryonville, Crawford County.—In 1892, Mr. H. Roberts sent to the Smithsonian Institution considerable parts of a skeleton of Elephas columbi, including the hinder part of a lower molar, probably the penultimate. These remains had been found in digging a cellar in Tryonville, at a depth of 7 feet. Tryonville is on Oil Creek and in the eastern part of the county. From Mrs. A. A. O’Dell, Niagara Falls, New York, daughter of Mr. Roberts, the writer learns that the cellar was at a height of 80 feet above the level of Oil Creek. Since that time the creek has abandoned its channel at that point.
