4. _Frankstown, Blair County._—In 1908 (Ann. Carnegie Mus., vol. IV, p. 231), Dr. W. J. Holland reported remains of a number of peccaries found in a bone cave at the place named. He mentioned especially _Dicotyles pennsylvanicus_, but thought it belonged properly in _Platygonus_. It is probably to be referred to _Mylohyus_ as _M. pennsylvanicus_. OHIO. (Maps 20, 36.) 1. _Wilmington, Clinton County._—In the collection of the Archæological and Historical Museum of the University of Ohio, at Columbus, are considerable parts of the jaws, teeth, and other parts of the skeleton of a specimen of _Platygonus compressus_ exhumed at a point about 4.5 miles north of west of Wilmington. The locality is given as being in the northeast corner of Adams Township, south of the road running northeast and southwest between Todd and Dutch Creeks; also about 0.6 mile south of the north line of Adams Township and about 0.75 mile from the east line. It would therefore be near the second northwesterly directed loop of Todd Creek in that neighborhood. 2. _Columbus, Franklin County_.—In 1875 (Proc. Amer. Assoc. Adv. Sci., vol. XXIII, Hartford, pp. 1–6; also in Cin. Quart. Jour. Sci., vol. II, pp. 1–6), J. H. Klippart gave an account of the finding of about a dozen skeletons of _Platygonus compressus_. These were buried in 2 “nests” not far from each other. The bones were rather brittle and were damaged somewhat in exhuming them. The place of burial was in the bank (apparently the right) of Olentangy River, at the crossing of Olentangy and Montgomery streets. The remains were here buried in a sand-bank. One lot of 6 of the smallest animals was found in penetrating the sand bank about 20 feet from the entrance and at a depth of 8 feet from the surface. They were embedded in calcareous clay and sand. The other 6 and largest animals were found about 6 feet farther in and about 4 feet deeper. It appears that all the animals were lying with their snouts directed toward the southeast. Klippart thought that they had been destroyed suddenly and violently. It is, however, probable that they had been frozen in their beds during a winter storm. Of these skeletons it appears that half went to Professor O. C. Marsh, of Yale University, and the present writer has had the privilege of studying them. The geological age of the animals will be considered on page 330.
