See Fig. 1 for key to foramina. to the fenestra vestibuli; the facial nerve and the stapedial artery evidently shared this one opening. Channels showing the courses of blood vessels are present on the surface of the promontorium. The main channel for the internal cartoid artciy, pos- sibly the promontory branch, begins just anterior to the jugular foramen; midway across the promontorium it turns antero- dorsally and runs to the medial portion of the middle lacerate foramen. A channel for the stapedial artery curves postero- dorsally from the point where the internal carotid turns anteriorly, and it leads to the fenestra \'estibuli. The bulla is preserved on one specimen,.
