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.

1. Stark County.—In Princeton University is a large lower left hindermost molar catalogued as having been found in Stark County. The tooth has 24 ridge-plates and is worn back to the fourteenth from the front. The length from the front of the tooth to the base of the last plate is 315 mm. There is no exact record of the locality. The Grand River moraine of the Wisconsin ice covers most of this county, so that the animal probably lived after the ice had disappeared from that vicinity.
2. Amboy, Ashtabula County.—In the collection of the Buffalo (New York) Natural History Society is a small elephant tooth, evidently a second milk molar, found at Amboy. It is regarded by the writer as belonging to Elephas columbi. There are present 7 ridge-plates and all have suffered wear. The length from front to rear is 114 mm.
In the Case School of Applied Science, Cleveland, is a large lower right hindermost molar of an elephant found at Amboy, in the extreme northeastern corner of the State. There is a description and figure of this tooth in the Scientific American for January 23, 1904, on page 60. It is there called Elephas primigenius. It presents 23 plates and front and rear talons; the length from the base in front to the rear of the hinder talon is 295 mm. There are from 6 to 8 plates in a 100–mm. line. The tooth was found between 1890 and 1900 in a gravel-pit near Amboy, worked by the Lake Shore Railroad. In the same pit was discovered a tusk which may have belonged to the same animal. A tooth of Elephas primigenius at the Buffalo Society of Natural History was probably found at the same place. The writer is informed by Professor Frank R. Van Horn, of the Case School of Applied Science, that the deposit consists of interstratified sands and gravels and is supposed to be the delta formation of the old Conneaut River. Its thickness was from 50 to 75 feet. In this deposit was driftwood, arranged in such regular order that it suggested the idea that it had formed part of a corduroy road.
