TAPIR , any existing representative of the perissodactyle See also:section of ungulate mammals with five front and three See also:hind toes, and no See also:horn. Tapirs are an See also:ancient See also:group with many of the See also:original characters of the See also:primitive Ungulates of the Oligocene See also:period, and have undergone but little See also:change since the See also:Miocene. On the fore-feet the four toes correspond to the second, third, See also:fourth and fifth fingers of the human See also:hand. The toes are enclosed in hoofs, and the under See also:surface of the See also:foot rests on a large See also:pad. Tapirs are massively built, with See also:short stout limbs, elongated See also:head, and the See also:nose and upper See also:lip produced to See also:form a short flexible See also:trunk. The five existing See also:species may be grouped into two sections, the distinctive characters of which are only recognizable in the See also:skull. (A) With a See also:great anterior prolongation of the ossification of the nasal See also:partition, extending in the adult far beyond the nasal bones, and supported and embraced at the See also:base by ascending plates from the upper See also:jaw, forming the genus or sub-genus Tapirella. To this See also:division belong two species, both from Central See also:America, Tapirus bairdi and T. dowi. The former is found in See also:Mexico, See also:Honduras, See also:Nicaragua, See also:Costa Rica and See also:Panama; the latter in See also:Guatemala, Nicaragua and Costa Rica. (B) With the bony partition not extending farther forward than the nasal bones (Tapirus proper). This includes three species, T. indicus, the largest of the genus, from the See also:Malay See also:Peninsula (as far See also:north as See also:Tavoy and See also:Mergui), See also:Sumatra Species.

and See also:Borneo, distinguished by its See also:peculiar coloration, the head, See also:neck, fore and hind limbs being glossy See also:black, and the inter-mediate See also:part of the See also:body See also: Tapirs appear, however, to have become See also:extinct in See also:Europe before the See also:Pleistocene period, as none of their bones or See also:teeth have been found in any of the caves or alluvial deposits in which those of elephants, rhinoceroses and hippopotamuses occur in abundance; but in other regions their distribution at this See also:age was far wider than at See also:present, as they are known to have extended eastward to See also:China (T. sinensis) and westwards over the greater part of the See also:southern See also:United States of America, from See also:South Carolina to See also:California. Thus there is no difficulty in tracing the common origin in the Miocene tapirs of Europe of the now widely separated American and See also:Asiatic species. It is, moreover, interesting to observe how slight an amount of variation has taken See also:place in forms isolated during such an enormous See also:time. See See also:PERISSODACTYLA. (W. H. F.; R.
