In Area Between the Wabash and Kankakee Rivers.
7. Near Francisville, Pulaski County.—The writer has received from Mr. W. D. Pattison, of Winamac, Indiana, two photographs of a tooth of an elephant which quite certainly belonged to Elephas primigenius. The locality is in the southwest quarter of the southeast quarter of section 20, township 30 north, range 4 west. According to Leverett’s map, this is in a tract covered by Wisconsin ground moraine and but little above the level of the Kankakee marshes, the 700–foot contour-line being not far away. Just west of the place is a part of the Marseilles moraine. The spot must be very near Metamonong Creek.
11. Rochester, Fulton County.—The American Museum of Natural History, New York, has a well-preserved skull of Elephas primigenius which had been exhumed in the vicinity of Rochester. The exact locality is not known to the writer.
The specimen is supposed to have been a female. The tusks are slender and only 700 mm. long. The hindermost upper molar is present. It is 245 mm. long and 75 mm. wide. There are 10 plates in a 100–mm. line. There appear to be 25 or 26 plates present. The second molar was still in use and about 130 mm. long. This was a large elephant, the measurements falling only slightly below the specimen in that museum which was obtained near Fairmount, Grant County.

1. Cairo, Alexander County.—The collection of the Buffalo Society of Natural History contains a tooth of an elephant, an upper left second true molar, apparently belonging to Elephas primigenius. It is reported to have been found at Cairo, at a depth of 95 feet below the bed of Ohio River. It was probably discovered in preparing the foundations of a railroad bridge. It has 15 ridge-plates, besides the front and rear talons. The length of the base, in a straight line, is 156 mm. There are 10 plates in a line 100 mm. long, a number too great for E. columbi. The tooth is unworn. It has suffered no injury, as from being rolled along the river bed; hence the animal probably died near where the tooth was found. It is impossible to assign the tooth with certainty to any particular stage of Pleistocene times. It seems most probable that the animal lived at the time the Illinoian ice-sheet was only a few miles away; the depth at which it was buried in the filling of the river channel appears to lend confirmation to this view.
2. Ashland, Cass County.—In the U. S. National Museum (No. 2195) are some remains of an elephant, referred to Elephas primigenius, found at Ashland in the spring of 1901. The remains consist of pieces of one tusk, the symphysis of the lower jaw, the right and left upper hindermost molars, the right lower last molar, a fragment of the rear of a much-worn upper second molar, and another of a correspondingly worn lower second molar. They were found in tilling a farm near Ashland by Mr. J. W. Arnold, of Jacksonville, Illinois.
The upper teeth resemble greatly those figured by the writer in his report on the Pleistocene Mammalia of Iowa (Iowa Geol. Surv., vol. XXIII, plate LIX); but the teeth from Ashland are more worn than those found in Milwaukee. The last molars from Ashland are worn back to about the eleventh ridge-plate, and the second molar is worn so that only its rear portion remained. The length of the upper molars is about 275 mm. The height of the eleventh plate is 185 mm.; the breadth of the grinding-surface is 90 mm. One or two of the hinder plates are missing, but evidently there were at least 24. There are 9 or 10 ridge-plates in a 100–mm. line on the worn surface; farther towards the base 8 plates in the same space. The ridge-plates are little bent; the enamel is thin and little sinuous in its way across the worn surface of the tooth.
The lower last molar is 315 mm. long, 152 mm. high, and 85 mm. wide. It is thus longer than the upper molars, slightly narrower, and not so high.
