3. Milroy, Mifflin County.—In 1882, Leidy described (Proc. Acad. Nat. Sci. Phila., 1882, p. 302) a species of peccary found in a limestone cave in the county named, but he gave no more exact information; nor did he do so in his two subsequent references to it in 1889 (Trans. Wagner Inst., vol. II, p. 49; Ann. Rep. Geol. Surv. Pennsylvania for 1887, p. 12, plate II, figs. 1, 2). The specimen is in the Academy of Natural Sciences at Philadelphia. In the Pennsylvania survey, as quoted, the giver is called John Schwarzer. The name of the species is Platygonus vetus. The writer has been informed by J. C. Swigart, county surveyor of Mifflin County, that the proper name of the donor of the specimen was John Swartzell, a former surveyor who lived near Milroy and who was much interested in geology.

From Professor Mosheim Swartzell, of Washington, D. C., son of John Swartzell, the writer has received a letter in which are given this son’s recollections regarding the finding of the specimen in question. He states that it was discovered in Naginey’s limestone quarry, 1.5 miles south of Milroy. It came from a considerable, but now unknown, distance from the surface and was first noticed in the débris of the quarry. While Mr. John Swartzell was observing it, an ignorant workman struck it with a tool and damaged it, exclaiming that it was only the jaw of a hog. It was later sent to Philadelphia. Professor Swartzell writes that there was a cave not far away, but that the jaw was not found in it; it probably had fallen down into a crevice of the limestone.

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.

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].

3. Chalfants, Perry County.—In the collection of the Archæological and Historical Museum at the University of Ohio are considerable parts of a specimen of Platygonus compressus found not far from Jonathan Creek, about a mile northeast of Chalfants. The locality, as given the writer by Professor W. C. Mills, is as follows: center of southwest quarter of section 14, township 17 north, range 16 west. The name of the political township is Hopewell. The locality appears to be on the area covered by Illinoian drift. This fact makes it possible that the animals lived during the Sangamon stage.

4. Lisbon, Columbiana County.—In the collection just mentioned is the left ramus of a lower jaw of a peccary which the writer referred with doubt to Mylohyus nasutus Leidy. It lacks so much of the front end that only 18 mm. of the symphysis is present; also, the ascending ramus is broken off. There are present the 3 milk molars and the first molar, but this is yet in its cavity in the bone. A comparison with Leidy’s M. pennsylvanicus seems to show that the jaw did not belong to that species. Of M. nasutus no lower jaw is known.
