1. Port Kennedy, Montgomery County.—From the noted bone cave at Port Kennedy a number of species of Megalonyx have been described. The presence of this genus was first announced by Wheatley (Amer. Jour. Sci., ser. 3, vol. I, p. 384). Cope, in 1899 (Jour. Acad. Nat. Sci., Phila., vol. XI, pp. 211–219), admitted the occurrence of 4 species, Megalonyx wheatleyi, M. loxodon, M. tortulus, and M. scalper. It must be left to future investigations to determine the status of these species. M. jeffersonii was not recognized by Cope in the materials found in the cave. Of M. loxodon, only a single upper canine molar was found. Of M. wheatleyi, numerous specimens were secured, including considerable parts of crushed and decayed skulls. M. tortulus was represented by a considerable number of teeth; M. scalper by only a single “canine-molar.” On page [312] will be found a list of the species of vertebrates associated with these sloths. Of Mylodon, Wheatley (op. cit., p. 384) had a single ungual phalanx which Cope (op. cit., p. 210) thought belonged probably to M. harlani.
2. Frankstown, Blair County.—Remains of an undetermined species of Megalonyx have been reported from a bone cave at this place by Dr. W. J. Holland (Ann. Carnegie Mus., vol. IV, 1908, p. 231). The associated species are listed on pages [321]–[322].

1. North Fairfield, Huron County.—In the Norwalk, Huron County, Museum there are various bones of Megalonyx jeffersonii which were obtained about 7 miles from North Fairfield. The writer learned of the discovery of this skeleton from Mr. Roe Niver, a student of the University of Illinois. Unfortunately Mr. Niver died before the writer could obtain all the desired information. A part of the skeleton was in his possession and is probably in the possession of his family, but the writer has been unable to secure any information from them. The bones were found at a depth of a few feet in a hackberry swamp and were considerably scattered. In the search for these the bones which form the type of Bison sylvestris Hay were found. The locality is within the area of the Wisconsin drift-sheet and evidently the animal lived there after the ice had retired from the region.
2. Millersburg, Holmes County.—In the University of Ohio there is a mounted specimen of Megalonyx jeffersonii containing a considerable part of the skeleton; the missing portions are replaced artificially. The remains were found in the eastern part of Holmes County just north of the terminal moraine of the Wisconsin drift-sheet. This moraine had led to the formation of a marsh, and in this the animal ended his life. The place was said by Orton to be 6 miles east and a mile north of Millersburg. The skeleton lay on shell marl beneath 6 feet of peat. The remains have been described by Claypole (Amer. Geologist, vol. VII, 1891, pp. 122–132, 149–153) and by Hay (Geol. Surv. Indiana, vol. XXXVI, 1913, p. 558; Geol. Surv. Iowa, vol. XXIII, 1914, p. 110).

The only member of the order of Xenarthra that has yet been found in this State is Megalonyx jeffersonii, and this in only one place, viz, Evansville.
