In 1861 (1st Bien. Rep. Geol. Surv. Michigan, p. 132), Professor Winchell mentioned this tooth and stated that it had been found in the northern part of the county while a ditch was being made. The locality is, therefore, north of the moraine referred to above.
1. _Terre Haute, Vigo County._—In the State Museum at Indianapolis is a fine lower left molar of _E. columbi_, labeled as found, in 1896, near Terre Haute, on the farm of Aaron Conover, and presented by Earl Conover. Mr. Herbert C. Anderson, county surveyor of Vigo County, informed the writer that the farm is located in the southwest quarter of section 9, township 12 north, range 9 west. This is 3.5 miles north of Terre Haute. The place is near Wabash River and the deposit is probably outwash from one of the ice-sheets. The depth at which the tooth was found is given as 18 feet. The length from the top of the anterior plate to the base of the hindermost is 380 mm.; width of worn face 100 mm. The hinder plates lean strongly toward the front and there are 6 plates in 100 mm.
2. _Monrovia, Morgan County._—The collection of the State Museum at Indianapolis contains the hinder half of what appears to be the lower right last molar. This was presented January 10, 1911, by David Hobson, of Monrovia, Indiana, and is labeled as found 1.5 miles southeast of Monrovia, in a gravel bar in Sycamore Creek. There are present 13 plates, considerably flexed as they rise from base to summit.
According to Leverett’s glacial map of Indiana, Monrovia is situated on the northern edge of the Shelbyville moraine. The tooth seems to have been found in Sycamore Creek, on the moraine or near its southern border, not far from the northern border of the Illinoian drift area. While the possessor of this tooth probably lived during some period of the Wisconsin stage, it is possible that the tooth had been washed out of some deposit of the Illinoian or of some interglacial deposit laid down between the Illinoian and the Wisconsin stages.
3. _Windfall, Tipton County._—In the Morrill collection, in the University of Nebraska, Lincoln, there are two teeth, an upper and a lower last molar, secured at Windfall by Professor Erwin H. Barbour. These teeth have been described and illustrated by the writer (36th Ann. Rep. Geol. Surv. Indiana, p. 742, plates XXV, XXVI). Windfall is situated on Wisconsin drift, some miles west of the more or less morainic belt which marks the northwestward continuation of the Union City moraine.
