Watson's figure of this part is based on inconclusive evidence, and I have no doubt that better preserved material will show that, in this region, Scymnognathus agrees with other Gorgonopsians, viz. that the palatines meet in the median line, that the pterygoids do not meet the prevomers, and that there is no unpaired median bone. An imperfect weathered axis is the basis on which this element was BPP

Vid. = Vidian foramen. figured by Watson. The anterior cervicals are much better shown in Hipposaurus, Aelurognathus, and Arctognathoides recently described by me, and these show that Watson was correct in his restoration. Watson's figures of the sectioned snout (49369) are correct. In fig. 12, No. 7, the inner pair of strips labelled "pterygoid" are open to discussion. There is no doubt as to their presence as separate strips of bone; what must be decided is whether they represent the anterior extremities of the pterygoids or not. If they do, it means that the palatines do not meet in the median line and that the ptery- goids meet the prevomers, which would be contrary to the condition in at least nine other Gorgonopsia. I believe that the explanation is that they represent a dorsal pterygoidal girder which is not exposed in ventral 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.
