Mammals, Fossil. 168 TJNGTJL1TA. especially those from Burma, China, and Japan, show excessive plication of the enamel, and thereby approximate to E. indicus, although with a lower ridge-formula1. In their height and number of ridges, the teeth are intermediate between those of E. hysudricus and E. indicus; and were it not for the peculiar character of the cranium, the species might be regarded as the direct link between the two.

In their height and number of ridges, the teeth are intermediate between those of E. hysudricus and E. indicus; and were it not for the peculiar character of the cranium, the species might be regarded as the direct link between the two. The adult cranium is characterized by the presence of a bold, overlapping, transverse ridge on the frontals2, which appears to be wanting in E. antiquus. On the occipital aspect the great depth of the fissure for the ligamentum nuchas indicates that the species is probably a descendant of E. hysudricus. Hob. India, Burma3, China4, and Japan5. In India the species occurs in the Pleistocene of the Narbada valley, and it is probable that the other specimens are from strata of equivalent age. The woodcut (fig. 29) represents a molar from the Pleistocene of Japan, Fig. namadicus.—The second right upper true molar; from the Pleistocene between Kanagawa and Tokio (Yedo), Japan, f. The lower border of the figure is the inner border of the specimen. (From the Quart. Journ. Geol. Soc.) 1 One of the Japanese specimens was referred by Leith-Adams to E. indicus. 2 It has been suggested by Leith-Adams (' British Fossil Elephants' [Mon. Pal. Soc], p. 52) that this feature is partly due to crushing—a view disproved by its occurrence in numerous specimens in the Indian Museum, Calcutta (see ' Palse- ontologia Indica,' ser. 10, vol. i. p. 281, and the writer's ' Catalogue of Pleisto- cene and Prehistoric Vertebrata in the Indian Museum,' p. 14 (1886). 3 Specimens from the Irawadi Valley in the Indian Museum. 4 Vide p. 169, No. 29007. 5 Naumann, ' Paheontographica,' vol. xxviii. art. 1, p. 25 (1881)..
