1. Brookfield, Tioga County.—In the U. S. National Museum (No. 193) is a part of an upper molar of Elephas primigenius sent in 1889 by Mr. Ira Sayles, of Brookfield. It was found along the north fork of Cowanesqua Creek. The hinder 13 plates are present. Mr. Sayles, in a letter to the present writer, stated that originally the tooth had 8 more enamel plates. This would seem to indicate that the tooth is the hindermost molar. Ten of the plates on the side of the tooth are crossed by a line 100 mm. long. The animal probably belonged to the Late Wisconsin stage.

2. Chadd’s Ford, Chester or Delaware County.—In the collection of the Academy of Natural Sciences, Philadelphia, is a fragment of an elephant tooth labeled as found in kaolin deposits owned by W. W. Jeffries and G. B. Dillingham. The specimen was described by Leidy (Proc. Phila. Acad., 1875, p. 121). In this fragment are six ridge-plates, and a line crossing them measures 60 mm. The tooth appears to have belonged to Elephas primigenius. Leidy stated that it had been found lying on the kaolin bed, 8 feet below the surface.

In the same collection is a fragment of a tooth to be referred to E. primigenius, consisting of three plates, apparently presented by I. McClure. It is said to have been found in Chester County, but no more exact locality was named.

3. Harvey’s, Greene County.—From Mr. Andrew J. Waychoff, of Waynesburg, the writer has received for examination a lower jaw of a young individual of Elephas primigenius found near the place named. Professor Edwin Linton sent the information that it was discovered in the bed of Gray’s Fork of Ten mile Creek, about 0.25 mile west of Graysville. In the jaw are the second true molars, right and left, slightly worn. The length of each is 165 mm., the width 62 mm.

4. Lone Pine, Washington County.—From Professor Edwin Linton, of Washington and Jefferson College, the writer received a photograph of an elephant tooth found at Lone Pine. This place is located on Little Ten mile Creek, 7.25 miles southeast of Washington. Professor Linton writes that a 100–mm. line crosses ten of the ridge-plates on the side of the tooth. The photograph shows that there are 20 plates present, of which 12 are worn more or less.

5. Beaverdam, Erie County.—In 1828 (Amer. Jour. Sci., vol. XIV, p. 31), Mr. Jeremiah Van Rensselaer described a tooth which must have been that of Elephas primigenius. It had been found near Lake Erie, at a place called Beaverdam, near a small rivulet, and at a height of 600 feet above the lake. He stated that there were 13 layers of enamel in a line 4.5 inches long. The tooth was sent to the Lyceum of Natural History, New York, but was probably destroyed in a fire at the old American Museum of Natural History.
