The mastoid, 8, overlaps the alisphenoido-parietalsuture by a squamous articulation, projects far behind the occipitalsurface of the skull, and there supports the tympanic column by anoblique terminal flat articular facet (s, and fig. 4, s). The parietal,7, as in the Crocodilia, is imperforate. In Mosasaurus Hoffrnanni (fig. 6) there is a large foramen parie-late (7 *), which, as in the Monitor, is wholly in the parietal, 7. Theparietal bifurcates posteriorly; its prongs, 7, extend backward andoutward, and articulate with the mastoid, 8; and this bone curves out-ward and downward to join the squamosal, 27, and, with it, to formthe articular surface for the tympani
