The tooth is a lower right hindermost molar, worn on only about 8 plates and not to the base in front. About 7 plates are missing from the rear. There are present 17 ridge-plates. The length along the base is 250 mm.; originally it must have been close to 350 mm. On a lateral face there are only about 7 of the plates in a 100–mm. line. Nevertheless, the writer regards the tooth as belonging to _E. primigenius_. It is unusually long for the species; hence the plates are thicker, quite as thick as some specimens of _E. columbi_. However, the enamel, as shown on the worn face, is much thinner than that of _E. columbi_ and comparatively little folded. The plates are only moderately concave on the hinder face. The height of the tooth at the ninth plate is 140 mm. 6. _Lewiston, Niagara County._—From Mr. C. A. Hartnagel the writer received information of the finding of a tooth of an elephant at Lewiston; and later the tooth was sent for examination. It proved to belong to _E. primigenius_ and to be the upper right hindermost molar. Inasmuch as it is worn to the base in front and as the large anterior root is missing, some plates, probably at least two, are missing. There are 22 present. The tooth is worn back to the tenth from the rear. The length, as the tooth is preserved, is 275 mm. The height at the tenth plate from the rear is 160 mm., not including the base of the roots. The greatest thickness is 85 mm. On the lateral face are 9 plates in a 100–mm. line. The base of the tooth is straight; the hinder border of the crown, arched. Mr. Hartnagel stated that besides the tooth some fragments of other teeth and two atlases were found at the same place. Evidently more than one animal was present. The remains here described were discovered at least 20 feet below the gravel-bed at that place and 80 feet below the level top of the terrace at points where it was not eroded. The bones and teeth appear to have been scattered through a bed of sediments at least 6 feet in thickness. The remains described above were mentioned by Kindle and Taylor on page 13 of Folio 190 of the U. S. Geological Survey, but were referred to a mastodon. The writers described the deposit in which the tooth was found. The geological age was believed to be that of the Iroquois episode of the Wisconsin. NEW JERSEY. (Map 11.) 1. _Trenton, Mercer County._—In the collection at Princeton University is an upper right last molar of this species recorded as having been found at Trenton. It was discovered in the bluff of Delaware River, just outside the fence of the Riverview cemetery, about 12 feet from the surface. The tooth was given to Dr. Marcus S. Farr by Dr. C. C. Abbott, and to him by Dr. Ward, of Trenton. Dr. Abbott was certain that it was found in the Trenton gravels. Further mention will be made of this on page 304.
