The remaining figures. Figs. 5, 6, 7, 8, represent the worn surfaces of molars or grinding teeth of the extinct species of Elephants termed Mammoths, (Elephas primigenius, of M. Bojanus.)

Fig. 9, shows the structure of part of the tooth.

These were regarded by Mr. Parkinson as referable to two or more species of Mammoth; but Professor Owen, after an examination of the vast number of specimens that modern researches have brought to light, and which are deposited in the public and private collections of Great Britain, concludes that the specimens here figured belong to but one species. The differences observable in the surface of the crowns, are due to abrasion, and to the latitude of variety to which the highly complex molars of this extinct Elephant were subject.[73]
