Posterior to the very prominent transverse pterygoid flanges the basis cranii lies in a more or less horizontal plane, whereas anteriorly the palate is in anterior direction directed upwards. This is accentuated by the upward retreat of the alveolar border of the premaxillaries. The most prominent features in the ventral aspect of the :skull are: the strong and deep lateral flanges of the pterygoid, the strong xeniform dentigerous bosses of the palatines, the retreat of the alveolar border.
