These small nodules of cartilage raise the dorsal part of the ary-epiglottic fold in the form of two rounded eminences, termed respectively the tuberculum cuneiforme [Wrisbergi] and the tuberculum corniculatum [Santorini]. On either side of the laryngeal opening there is, in the pharynx, a small recess directed downwards which presents a wide entrance, but rapidly narrows towards the bottom. It is termed the recessus piriformis, and is of importance to the surgeon, because foreign bodies introduced into the pharynx are liable to be caught in this little pocket. On the medial side the recessus piriformis is bounded by the arytenoid cartilage and the ary-epiglottic fold, whilst on the lateral side it is limited by the inner surface of the laniinse of the thyreoid cartilage, clothed with the pharyngeal mucous membrane. Vestibulum Laryngis.—The vestibule of the larynx is the uppermost compart- ment of the cavity of the larynx. It extends from the laryngeal aperture to the ventricular folds. In its inferior part it ex- hibits a marked lateral compression. Its width, therefore, diminishes in the vertical direction, whilst, owing to the obliquity of the laryngeal aperture, its depth rapidly diminishes ventro- dorsally. Ventrally it is bounded by the dorsal surface of the epiglottis, clothed with mucous membrane. This wall passes obliquely from its superior end in an inferior ventral direction, and becomes narrower as it approaches the ventral or anterior ends of the ventricular folds. The superior part of the dorsal surface of the epiglottis is convex, owing to the manner in which the upper margin is curved ventrally towards the tongue; caudal to this there is a slight concavity, and still more caudally a marked bulging or convexity, over the superior part of the thyreo-epiglottic ligament. This swelling is called the tuberculum epiglotticum, and it forms a consp
