The gall-bladder is generally well developed and attached to thelight central lobe, except in lildiuilophidm, where it isconnected with the left central. In most species the hyuid bones are simple, consistingof a chain of slender, elongated, cylindrical bones connect-ing the small basi-hyoid with the cranium, while thepliarynx is short, the larynx shallow with feebly developedvocal cords, and guarded by a short acutely-pointedepiglottis, which in some genera (Harpyia, Vampyrus,e.;i.) is almost obsolete. In the £pomophori, however, we£nd a remarkable departure from the general type: the pharynx is long and very capacious, the aperture of thelarynx far removed from the fauces, and, opposite to it, acanal, leading from the narial chambers, and extendingalong the back of the pharynx, opens ; the laryngeal cavityis spacious and its walls are ossified; the hyoid bone is.
