The principal existing orders are Testidunata or Cheloniaturtles), Crocodilia Lacertillalizards), Ophidiaserpents), and Rhynchocephala; the chief extinct orders are Dinosauria Theremorpha Mosasauria Pterosauria Plesiosauria Ichtyosauria.

    • reptilia In zoology:
    • reptilia (a ) In Linnæus's system of classification (1766), the first order of the third class Amphibia, including turtles, lizards, and frogs. See Amphibia, 2 .
    • reptilia A class of cold-blooded oviparous or ovoviviparous vertebrated animals whose skin is covered with scales or scutes; the reptiles proper. There are two pairs or one pair of limbs, or none. The skull is monocondylian. The mandible articulates with the skull by a free or fixed quadrate bone. The heart has two auricles, generally not two completed ventricles; the ventricle gives rise to two arterial trunks, and the venous and arterial circulation are more or less mixed. Respiration is pulmonary, never branchial. No diaphragm is completed. There is a common cloaca of the digestive and urogenital systems, and usually two penes, sometimes one, seldom none. There are an amnion and an allantois. Reptilia thus defined were formerly associated with batrachians in a class Amphibia; but they are more nearly related to birds, and when brigaded therewith form their part of a superclass Sauropsida. The only living representatives of Reptilia are turtles or tortoises, crocodiles or alligators, lizards or Baurians, and snakes or serpents, respectively constituting the four orders Chclonia, Crocodilia. Lacertilia, and Ophidia; and one living lizard, known as Hatteria, Sphenodon, or Rhynchocephalus, forming by itself an order Rhyuchocephalia. In former times there were other orders of strange and huge reptiles, as the Ichthyopterygia or Ichthyosauria, the ichthyosaurs; Anomodontia; Dinosauria, by some ranked as a subclass and divided into several orders; Ornithosauria or Pterosauria, the pterodactyls; and Plesiosauria or Sauropterygia, the plesiosaurs. See the technical names, and cuts under Crocodilia, Ichthyosauria, Ornithoscelida, Plesiosaurus, Pleurospondylia, pterodactyl, and Python.
