lower. A lower second (antepenultimate) milk molar accompanied 

 the teeth of the young individual. A section was made and polished 

 in order to show the structure (pi. 9, fig. 7). There appear to be 

 present three plates and front and rear talons. The crown is 19 mm. 

 long and 15 mm. wide. The penultimate milk molars above de- 

 scribed have lost much of their cement. There are present the hinder 

 halves of the uppe'r third milk teeth of two other individuals, both 

 having the same white color as the teeth just described. One of these 

 (pi. 11, fig. 6. Cat. No. 9232) preserves the cement between its plates. 

 There are in the collection several fragments of other third milk 

 molars, and the writer has seen a similar tooth in the collection of 

 the San Antonio Scientific Society. Indeed, it may be the fellow of 

 the lower milk tooth of the specimen which furnished the two penul- 

 timate milk molars and the one lower milk molar. 



If the remains just described belong to Elephas pnmigenius and 

 not to an unrecognized species, of whose validity the writer has 

 been unable to persuade himself, the known distribution of this wide- 

 ranging species becomes greatly extended in our country. The 

 writer has referred to E. primigeniu^ a large tooth now in the col- 

 lection at Ealeigh, North Carolina, and found a few miles north of 

 Beaufort. In the present paper he figures a fragment of a milk molar 

 which is in the collection from Whitesburg, Tennessee. It is a 

 smaller tooth than those from Bulverde. The writer has had sent 

 to him by Prof. Mark Francis, of College Station, Texas, a lower left 

 penultimate milk molar which was found near Temple, Bell County, 

 Texas. It is 62 mm. long and 32 mm. wide (pi. 10, figs. 3, 4). 



The teeth from Bulverde have the ridge plates so much thicker 

 than most specimens from Alaska and Siberia that one is naturally 

 led to inquire whether the former may not belong either to E. co- 

 lumbi or to E. imi)erator. Of E. columhi Leidy described a second 

 (antepenultimate) milk molar ^ and his figure has been copied by the 

 present writer; ^ but one can hardly rely on teeth of this order in dis- 

 tinguishing species. From Florida Leidy ^ described what he re- 

 garded as an upper penultimate milk molar; but his figure, repro- 

 duced by the present writer,* seems to show the concave surface of 

 wear of a lower tooth. The length of the tooth is 110 mm.; the 

 greatest thickness, 4G mm. This is nearly the size of the hindermost 

 milk molar of the Texas specimen and of others belonging to E. 

 primigenius. The present writer has described and figured,^ as an 

 upper penultimate milk molar of E. cohimhi, a specimen from the 

 phosphate beds of South Carolina. It is a little used tooth and
