Warsh asBrontotUcrimn, and by Cope as St/mliorodon, some of which appearto represent distinct generic modifications, but the synonymy ofthe group is at present much confused. The head was large andmuch elongated, as in the Rhinoceros ; but they had a pair ofstout diverging osseous protuberances like horn-cores on themaxillaries in front of the orbits. Theirmolar teeth were of asimple palceotlieroid type, and the incisors and canines were verymuch reduced. Their fore feet had four and their hind feet threeshort, stout toes. Their remains abound in the Lower Miocenestrata of North America. Family structure of the type of this family, Pala^othcrium, wasmade known by Cuvier, from speciiuens found in the Paris gypsumbeds (Upper Eocene). Fig. 108 gives an idea of its general appear-ance, not unlike that of a Tapir, which also it resembled in had, however, hut three toes on the fore feet. The dentitionwas i J, c I, p f, m | = 44. Many species and allied genera (as. Fig. 108.—Restoration of PaJxotherium (Upper Eocene). Curler. PcUaplothcrimn, an earlier form from the Middle Eocene, andAnchithcrium^ a later one from the Miocene) have been discoveredboth in Europe and North America. To some of these theancestral form of the modem Horses may be traced, tho transitionfrom this to the next family being formed by almost imperceptible C. Equine Section. Ijower molars formed of a pair of crescents complicated by the addition of columns or lobes at the inner extremities. Upper molars a modification of the palceotheroid type, but gradually {lassing as time advanced from the brachyodont to the hypsodontorm. Outer digits becoming gradually reduced, until, as in themodem Horses, there is but one (the third) functional digit on eachfoot. To th
