Fig. boundary of the large vertical occipital foramen, and thickened and smoothly rounded to form the inferior extremities of the two occipital con- dyles. These condyles are principally deve- loped from the ex-occipital elements (Jigs. 169, 171, 6, 6), which are expanded superiorly and terminate in an angle wedged in between the supra-occipital and petrous bones; they extend, but do not meet, above the occipital foramen, being separated by a notch closed by membrane in the recent state. The supra- occipital element (Jigs. 169 & 171, c) is a transversely oblong quadrilateral plate of bone; its short lateral margin is joined by a linear harmonia with the upper part of the os petro- sum, on each side; the wide anterior mar- gin is similarly articulated with the single parietal bone, and is slightly overlapped by its posterior margin; this representative of the deltoid suture runs straight across the posterior and upper part of the skull.
