CRANIAL STRUCTURE OF THE TITANOSUCHIAN 133 Associated with the holotype skull of acutirostris there were a number of skull fragments of other Anteosaurus skulls and in addition a large number of bones of the postcranial skeleton of more than one individual. I hope to be able to describe these bones of the postcranial skeleton in the near future. In the meantime a general statement here will be useful. As a whole the postcranial skeleton is lightly built without any trace of the massiveness so typical of all the hitherto known South African Deinocephalians. One's first impression is that the skeletal bones could belong to some large Therocephalian — associated, for instance, with a skull not very much larger than that of Scymnosaurus ferox. This applies particularly to the femur, which is a long bone with the proximal and distal ends hardly expanded and the shaft long and slender. Anteosaurus crassifrons Sp. Nov. (Figs. 11, 12, 13- Holotype. A good skull, but distorted by a simple shear. 11946, Buffelsvlei, Beaufort West. Coll. Boonstra and Marais. Skull large, but short and quat; maximum length 570 mm. Snout short, high and very wide. Intersquamosal width fairly small (330? mm.). Postfrontal boss fairly massive and prominent. Jugal boss massive, angular boss unknown. Fronto-naso-prefrontal swelling very massive with a very distinct step on to the anterior nasal surface and laterally strongly overhanging the sides of the skull. Pineal boss rounded, large and extending on to the frontal. Very sharp upward inclination of the premaxillary edge. The occiput is high, fairly wide, deeply concave, with a great posterior sweep of.
