Century Dictionary and Cyclopedia
    • ungulata In the Linnean classification, one of the primary divisions, a subclass or super-order, of Mammalia, including all the hoofed quadrupeds, the two Linnean orders Pecora and Belluæ (except the elephant and walrus, which Linnæus placed in Bruta, an order of his Unguiculata). The Ungulata were thus nearly equivalent to the orders Pachydermata, Solidungula, and Ruminantia, and correspond to the modern orders Artiodactyla (the ruminants, pigs, and hippopotamuses) and Perissodactyla (horses, tapirs, and rhinoceroses), together with the Proboscidea and Hyracoidea, and certain fossil groups, as the Ambiypoda. The term, like the correlated Unguiculata, has lapsed from a strict classificatory sense, but is still used as a convenient designation of hoofed quadrupeds collectively or indiscriminately.
