A classification based upon parallel evolution must, however, be unnatural. Family I.—Tapiridae.—These interesting animals, the tapirs, are found in swampy forest districts of Brazil and of Malay. Hence they form an instance of discontinuous distribution of a family. They form the base of the present-day Ferissodactyla as they have f toes and the teeth are bi-lophodont and brachydont. The upper molars show an external ridge connecting the two transverse ridges, thus approaching the rhinoceroses; the incisors are of average length and the third lower one resembles a canine. The dental formula is %\%%. There is a very slight proboscis or trunk. They feed upon the leaves and young shoots of trees. Fig. 341.—The American Tapir {Tapints a/nericamis). (From Flower and Lyddeker.). Tapirs occur in Eurt)pe and Asia in the Miocene strata, thus explain- ing the discontinuous distribution in this instance by a dying-out of the intermediate portions of a once widely and continuously distributed Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Masterman, Arthur Thomas; Parsons, John Herbert, Sir, 1868-1957, donor; S.
