ELEPHANT, the designation of the two existing representatives of the Proboscidea, a sub-order of ungulate mammals, and also extended to include their more immediate extinct relatives.
RUMINANTIA, a term employed by Cuvier to include all the existing artiodactyle ruminating ungulate mammals now classed under the groups Pecora, Tylopoda and Tragulina.
Ancient animal), a name applied by Cuvier to the remains of ungulate mammals recalling tapirs in general appearance, from the Lower Oligocene gypsum quarries of Paris.
PHENACODUS, one of the earliest and most primitive of the ungulate mammals, typifying the family Phenacodontidae and the sub-order Condylarthra.
The typical Phenacodus primaevus, of the Lower or Wasatch Eocene of North America, was a relatively small ungulate, of slight build, with straight limbs each terminating in five complete toes, and walking in the digitigrade fashion of the modern tapir.
Owen for that division of ungulate mammals in which the toe corresponding to the middle (third) digit of the human hand and foot is symmetrical in itself, and larger than those on either side (when such are present).
CHEVROTAIN, a name taken from the French to designate the various representatives of the mammalian ungulate family Tragulidae.
RHINOCEROS, the designation for such perissodactyle (odd-toed) ungulate mammals as carry one or more horns on the head, and their extinct relatives (see Perissodactyla).
AMBLYPODA, a suborder of primitive ungulate mammals, taking its name from the short and stumpy feet, which were furnished with five toes each, and supported massive pillar-like limbs.
&prtos, even, and &Lktvxos, a finger or toe, "even-toed"), the suborder of ungulate mammals in which the central (and in some cases the only) pair of toes in each foot are arranged symmetrically on each side of a vertical line running through the axes of the limbs.
Be this as it may, the North American mammals described as Moropus and Morotherium, in the belief that they were ground-sloths, are really referable to the ungulate group Ancylopoda.
TAPIR, any existing representative of the perissodactyle section of ungulate mammals with five front and three hind toes, and no horn.
HYRACOIDEA, a suborder of ungulate mammals represented at the present day only by the Syrian hyrax (Procavia syriaca), the "coney" of the Bible, and its numerous African relatives, all of which may be included in the single genus Procavia (or Hyrax), and consequently in the family Procaviidae.
ANTHRACOTHERIUM ("coal-animal," so called from the fact of the remains first described having been obtained from the Tertiary lignite-beds of Europe), a genus of extinct artiodactyle ungulate mammals, characterized by having 44 teeth, with five semi-crescentic cusps on the crowns of the upper molars.
TITANOTHERIIDAE (also known as Menodontidae and Brontotheriidae), a family of large rhinoceros-like perissodactyl ungulate mammals from the Oligocene and Eocene strata of North America.
For boss-footed, in reference to the cushion-like pads forming the soles of the feet), the scientific name of the section of ruminating artiodactyle ungulate mammals (see Artiodactyla) now represented by the Old World camels (see Camel) and the South American Llamas (see Llama) Characters.
The Amblypoda, on the other hand, are perhaps not far removed from the ancestral Proboscidea, which depart comparatively little from the generalized ungulate type.
