ART. 34 TYPE OF ELEPHAS EOOSEVELTI HAY HAY 3 



The remains above described appear to have been buried in the 

 Joess which covers the Illinoian drift around Ashland. Apparentlj^ 

 the animal lived during the late lowan stage or the early Peorian. 



2. A PALATE OF ELEPHAS ROOSEVBLTI FOUND IN WISCONSIN 



On plate 4 are presented two views of a palate of an elephant 

 which was found in Milwaukee and is preserved in the public 

 museum of that city. Figure 1 was originally published and the 

 specimen described by the writer in 1914.^ The specimen was there 

 referred to Elephas primigenius, but it is now regarded as belong- 

 ing to E. roosevelti. The specimen presents the second and third 

 upper molars of both sides and a part of each maxillary bone that 

 runs upward and forward from the second molar. 



Through the director, Dr. S. A. Barrett, and Prof. Ira Edwards, 

 curator of geology in the public museum, the writer has received a 

 photograph showing the palate as seen at right angles with the 

 grinding surfaces of the second molars (pi. 4, fig. 1). Of these 

 molars there remain only the hinder half of the crown and the 

 great hinder root. The length of the grinding surface is 175 mm. 

 In front the teeth are worn down to the common base of dentine. 

 In one tooth there remain 12, in the other 13 ridgeplates. The 

 front 2 or 3 loops of enamel inclose cement instead of dentine. It 

 will be noted (pi. 4, fig. 2) that the grinding surfaces of these teeth 

 make little more than a right angle with the lower border of the 

 hinder tooth; also only slightly more than a right angle with the 

 sheath of the tusks. These features appear to indicate a shortened 

 skull. The hindmost molar was just coming into use and no roots 

 had yet been developed ; probably about 4 plates were lost from the 

 hinder end in exhuming the specimen. Originally the greatest 

 diagonal measurement must have been close to 375 mm. There are 

 8 enamel plates in a 100 mm. line. This elephant died after the last 

 ice sheet had withdrawn beyond Milwaukee, but it is probably to 

 be credited to the Wisconsin glacial stage. 



3. A MOLAR OF ELEPHAS ROOSEVELTI FOUND IN OHIO 



In the U. S. Xational Museum is an upper left hindmost molar 

 (catalogue number 4761) found in Ohio and referred to EJephas 

 roosevelti The locality is in the northeast corner of Wayne Town- 

 ship, Darke County. The tooth is apparently the one mentioned by 

 A. C. Lindemuth in 1878.* It had been found in a creek just north 

 of Versailles. A record of it as EJephas primigenius is in the writer's 

 Pleistocene of North America east of the Mississippi, etc. (1023, p.
