The saddle-shaped notch found at the inferior angle ofthis aperture (fossa incudis) serves for the reception of the shortprocess of the incus. The eminentia pyramidalis (g) enclosingthe stapedius muscle arises from the medial surface of thiswall; this eminence, a small, bony process directed forwards,communicates with the facial canal by one or more small fissures ;a small, round opening exit of the stapedius tendon canbe seen at its apex. Inferior and somewhat external to the eminentia pyramidalisone often finds a more or less pronounced, irregular protuberance(d), which, as the author was the first to point out, is causedby the superior extremity of the styloid process—protuberantiastyloidea (Arch. f. 0.,
