The Pleurodonts are those lizards in which the teeth are anchylosed to the side of the dentary bone; Acrodonts, those with the teeth fixed to the upper margin or ridge of the jaw-bone; Thecodonts, those having the teeth implanted, either loosely, or anchylosed to the walls of their sockets. Lacertians are also said to be Pleodont (having solid teeth), or Cœlodont (hollow-toothed).
