The larynx is scarcely more developed in The cricoid is usually an incomplete ring, to which the arytenoids are attached, and the whole is placed just ventral to the median part of the hyoid, with which it is closely associated (fig. 259). In several reptiles there is a fold of the mucous membrane just in front of the glottis which is supposed to represent the beginnings of an epiglottis (infra), while in geckos and chameleons a pair of folds, running dorso-ventrally in the larynx, serve as vocal cords. The larynx is also rudimentary in the birds, its place as a vocal organ being taken by the syrinx to be described below, in connexion with the trachea. The arytenoids are frequently ossified in birds. Ph or.
