FROM THE KARROO BEDS OF SOUTH AFRICA. 661 



The jugal is large. It fomxis XBOst of the lower border of the 

 orbit, most of tlie postorbital avch, and a considerable part of 

 the zj^gomatic arch. 



The frontal is unusually large and wide. Its shape will be best 

 understood from the figure given. It has apparently a large 

 articulation with the postorbital, but a thin little strip of the 

 postfrontal is really wedged in between them. The frontal 

 passes back to the plane of the posterior end of the pineal 

 foramen. 



The postfrontal scarcely appears on the surface, but though 

 neai'ly hidden by the frontal and postorbital, it is really a bone 

 of appreciable size underneath. 



The postorbital is a large and powerful bone. It forms most 

 of the strong postorbital arch and the whole of the upper border 

 of the temporal fossa, and pretty certainly articulates with the 

 squamosal. 



The preparietal is unusually large. It passes far forwards 

 between the frontals, and posteriorly nearly surrounds the pineal 

 foiumen. 



The parietals appear to be ankylosed into a fairly large bone 

 lying mainly behind the pineal foramen. It forms a moderately 

 large, somewhat concave intertemporal I'egion. Anteriorly it 

 sends forward on each side a slender process between the frontal 

 and postorbital, and posteriorly a long process between the 

 postorbital and interparietal. 



The interparietal is a little broader than the middle part of 

 the parietal. Laterally it articulates with the large tabular. 



The occiput is fairly well preserved, and was probably much 

 like that of Bainia tigriceps, though some degree of crushing of 

 the squamosals gives it a. rather difterent appearance. The 

 occipital condyle is much shorter in the present species. 



The squamosals are, as in all Dicynodonts, large and powerful. 

 The shape of the zygomatic portion can be seen in the figure to 

 differ appreciably from that in B. tigriceps. 



The following are some of the principal measurements : — 



Greatest length (oblique) 500 mm. 



Greatest breadth 480 ,, 



Basal length 400 „ 



Width across nasal bosses 163 ,, 



Interorbital Avidtli 133 ,, 



Intertemporal width across parietals... 50 ,, 

 Intertemporal width across post- 



orbitals 86 „ 



Bainia haughtoni, sp. n. (Text-fig. 38.) 



In Haughton's paper on the Anomodonts in the tSouth 

 African Museum, recently published, he figures and describes a 

 skull (S. A. M. No. 3328) which he believes to be a young
