The IVth nerve has its foramen bounded by the supraoccipital and the parietal high up in the sidewall. The median part of the anterior septum is seen to be formed by the ptery- goid with the septosphenoid and parasphenoid and presphenoid forming the interorbital part of the septum. The basicranium (Fig. 15) In ventral view it can be clearly seen that the basicranium has a long sutural contact with the pterygoid and epiterygoid, with no movement between these two segments. A lateral process of the parabasisphenoid bounds the fenestra ovalis anteriorly and a similar process of the basioccipital bounds it postero-ventrally,.
