They present a vertical and horizontal prominence in the shape of the letter L, and partake of the form of the arytenoid cartilages. They are not always pre- sent, and their existence in man is denied by Cruveilhier :* this however is an error. Both Cuvierf and WolrTJ have confounded them with the cornicula or cartilages of Santorini. In the Quadrumana they are conspicuous, having the superior vocal ligaments attached to their bases, and they appear afterwards to con- nect them with the arytenoid cartilages. The cuneiform cartilages are sometimes described by Cruveilhier and other writers (though inac- curately) as the arytenoid glands. They serve as a link of connection between the arytenoid cartilages and superior ligaments. The epiglottis, from sort, upon, yXwrra, the tongue. Syn. KX^OV, Hipp.§ Liguln, Gal. Operculum, Cic. || Cartilago epiglottidis. Epiglotte, Fr. Ke/ildeckel, Germ. The epi- glottis is a cartilaginous valve, situated at the base of the tongue, and covering the opening of the larynx. The direction of the epiglottis is vertical, except during the act of deglutition, when it becomes horizontal. In form it has been compared to a cordate leaf, (Jig. 23,) or that of the artichoke. The di- mensions vary with the volume of the larynx. The anterior aspect of the epiglottis is convex, the posterior concave; it is partly free and partly connected: the free portion projects above the level of the base of the tongue. It is lined by the mucous membrane : the centre of its superior margin is
