Anteriorly it carries a large canine tooth which does not fill the alveolus ; but behind the canine I can see no trace of any molar teeth nor of alveoli for such teeth in either skull. The prefrontal is large and forms a large portion of the upper border of the orbit. The frontal is fairly short and seems to form portion of the supra-orbital border and meet the postorbital.

It may be, however, that part of the bone is in reality postfrontal. There are several irregular sinuses and pittings in the bone, but no definite suture is visible. If this be so, then the condition of the frontal would be similar to that in the Gorgon- opsia. There is no preparietal. The postorbital bar is long and the postorbital extends some distance along the parietal crest, being interlocked with the parietal. This crest is narrow as in the Therocephalia Cynodontia. There is an elongate pineaf foramen 25 mm. behind the post- orbital Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original South African Museum; South African Museum.
