Fortunately I have in my possession a less perfect skull also in a flinty hard matrix, but weathered out on top and showing beautifully most of the upper sutures.

. Annals of the South African Museum = Annale van die Suid-Afrikaanse Museum. Natural history. On Tapinocephalus and Two Other Dinocephalians. 429 The skull of Tapinocephalus described by Haughton, thougli nearly perfect, is, like most remains from the Tapinocephalus horizon, in a most intractable matrix, and nothing can be made out of the sutures. Fortunately I have in my possession a less perfect skull also in a flinty hard matrix, but weathered out on top and showing beautifully most of the upper sutures. The skull which I have was shown to me at Gans Kraal by Mr. M. J. van Wyk of Kookfontein. Like the skull described by Haughton, it is remarkably broad in comparison with the length. The breadth. YiG. 2.—Side view of skull of Tapinocej^halus atherstonei, Owen, ^ natural size. is about 440 mm., and though, as the greater part of the snout is lost, the length is uncertain it may be estimated at about 450 mm. The height from the lower side of the occipital condyle to the top of the parietal is 240 mm. The top of the skull is almost perfectly preserved, and it is mainly formed by six bones—a pair of parietals, a pair of frontals, and the upper and posterior parts of the nasals. The parietals are very much broader than long. Between them is a rather small pineal foramen. In front the parietal meets the frontal by a fairly long suture, but apparently does not meet the postorbital, at least not on the surface of the skull, being separated from it by the outward extension of the frontal. The parietal forms the upper wall of the narrow temporal fossa, and behind the fossa extends far outwards between the squamosal and the tabular. The frontal is an irregular pentagonal bone, with a long suture.
