Left ear, median view. , ampulla of anterior oblique semicircular canal; , ampulla of horizontal canal; aos., anterior oblique semicircular canal; )., ampulla of posterior canal; en., connection between utriculus and sacculus; , connection between sacculus and posterior oblique semicircular canal; , endolymphatic duct; hr., horizontal canal; ?., lagena; pos., pos- terior oblique semicircular canal; s., sacculus; u., utriculus. At its base the utriculus is connected with the sacculus (s.) by a recessus utriculi (at en.). The sacculus is pear-shaped and continues upward in the chimney-like endolymphatic duct, the outer opening of which we saw in a study of the skull {ed., p. 42, fig. 45). From the posterior part of the floor of the sacculus a tongue-like sac, the lagena (?.), projects backward and downward.
