Dr. W. D. Matthew informs the writer that on cleaning up the materials there proved to be present at least four individuals. One was represented by a very complete skull with portions of the tusks. There was another skull; also two lower jaws which appeared not to belong to either of the skulls. From the shortness and the diameter of the tusks it is believed that all the individuals were females. Besides the skulls there were many bones belonging to the trunk and the limbs. 36. _Macy, Miami County._—Near this place was found the fine skeleton of a mastodon which is mounted and on exhibition in the Public Museum at Milwaukee, Wisconsin. A figure of this has been published by the writer (36th Ann. Rep. Geol. Surv. Indiana, p. 659). This skeleton was found, according to Mr. H. L. Ward, director of the museum mentioned, in 1907, in the northwest quarter of section 29, township 29, range 4 east, between Macy and Deedsville. This locality is on the great moraine which lies north of Eel River and was produced by the ice fronts of the Michigan, the Saginaw, and the Lake Erie lobes. According to a sketch and some notes furnished to Mr. Ward by Mr. C. F. Fite, who secured the skeleton, it was lying at the lower end of an 8–shaped area of low muck land surrounded by rather high sandy land. The skeleton was buried at a depth of 4 or 5 feet, and the surface was miry and covered with water. Mr. Fite concluded from the position of the bones that the animal had become mired. He says in a letter to the present writer that the contents of the stomach had been preserved, but on exposure to the air became powdery like ashes. Mr. Fite writes that he took up portions of another mastodon in the southwest quarter of section 26, township 29 north, range 5 east (Perry Township), and that he has the lower jaw and teeth. This animal was found in an old pond which had a growth of buttonwood. The bones were in a blue clay, itself overlain by a rich black soil. Still another mastodon is reported by Mr. Fite from this region. This was found in the fall of 1915, in the northwest quarter of section 12, township 29 north, range 3 east. The remains were found at a depth of 4 feet and were in a pretty fair state of preservation, except the skull. The animal had been a large one. 37. _Peru, Miami County._—In the collection of Yale University is a lower left last molar, No. 11689, labeled as having come from Peru, but there is no other information. Peru is on the Wabash River, a few miles south of Denver. 51. _Jackson Township, Miami County._—Mr. Fite reports having found another mastodon in the southeast quarter of section 11, Jackson Township, Miami County (T. 25 N., R. 5 E.). This would be not far from Pipe Creek, between Somerset and Amboy, and some miles outside of the Mississinawa moraine. The writer has seen these bones, mostly vertebræ, and agrees with the identification.
