The manner of burial of these peccaries is puzzling and interesting. They were found in a hill, or drumlin, which stands out on a plain of considerable extent and whose long axis runs north and south. The elevation is 1,625 feet above sea-level. The drumlin is about 600 feet long, about 300 feet wide, and 40 feet high. It is composed of sand, gravel, and stones up to a foot in diameter. The bones are said to have been discovered by a contractor who was removing sand and gravel. The bones were at the south end of the drumlin and buried in a considerable pocket of sand. Those reporting the position of the bones place them at least 10 feet from the surface, and perhaps as much as 30 feet. Mr. Hartnagel thinks it is almost necessary to suppose that the skeletons were there when the drumlin was built. To the writer it would appear still more difficult to explain how they happened to be there at that time. NEW JERSEY. (Map 20.) 1. _Shark River, Monmouth County._—In 1869 (Jour. Acad. Nat. Sci. Phila., vol. VII, p. 387), Leidy described a tooth of a peccary shown to him by Timothy Conrad, but found by Dr. P. Knieskern, supposedly in a Miocene formation of Shark River. Leidy expressed the conclusion that the tooth resembled very closely a premolar of _Dicotyles nasutus_, now called _Mylohyus nasutus_. It is very probable that the tooth had gotten into Miocene materials by accident or that there was some error in the history, and that it really belonged to a Pleistocene peccary. PENNSYLVANIA. (Map 20.) 1. _Stroudsburg, Monroe County._—Leidy (Proc. Acad. Nat. Sci. Phila., 1880, p. 347) reported _Dicotyles nasutus_ from the Crystal Hill (Hartman’s) cave near Stroudsburg; but later (Ann. Rep. for 1887, Pennsylvania Geol. Surv., p. 8, plate II, figs. 3–6) he described the teeth and parts of the jaws as _Dicotyles pennsylvanicus_. This species will be found on page 310 under the name _Mylohyus pennsylvanicus_, in the list of fossils found in this cave. There too will be found a discussion of the location of the cave and the probable age of the remains.
