title: Observations on the primate hyoepiglottic complex.
abstract: In the species presented, the orifice to the subhyoid air sac is found at the tuberculum (when the epiglottis attaches at the level of the ventricle); here also is noted the presence of a cartilaginous island(s) just anterior to the duct. When seen in coronal section along the axis of the duct, the glandular elements cluster around the sac in the anterior supraglottic subhyoid wedge, in preference to the area around the ventricles.
