Kannemeyeria is the large Dicynodont which occurs in the Upper 

 Beaufort Beds. The skull is characterised by the high, narrow, convex 

 parietal crest which rises well above the interorbital plane, the broad 

 frontal region, the strongly ridged and rugose snout, and the large 

 nostrils. In these features it resembles to some extent Dicynodon 

 ijrandis, Eocyclops, and similar large forms from the Cistecephalus 

 zone, and also some of the species of Endothiodon. From the large 

 Lower Beaufort Dicynodons it differs in the size of the temporal 

 openings and in one or two other details. The parietal crest is more 

 pi-onouucedly convex. From Endothiodon it differs, of course, in the 

 lack of niolar teeth. 



The beautiful skull which forms the type of this species has been 

 described fairly fully as far as the external features go. It does not 

 show clearly whether a preparietal is present, but a second fragmen- 

 tary skull from the type locality seems to indicate that a small pre- 

 parietal formed the anterior border of the pineal foramen. The 

 foramen lies in a deep excavation as in Dicynodon </r<ni<li* and on one 

 side of the wall of this hollow two sutures can be seen joining in front 

 of the level of the pineal foramen, forming presumably the borders of 

 an anterior wedge of the parietal lying on one side of the median pre- 

 parietal. 



This same fragmentary skull has been sectioned longitudinally and 

 the brain-case between the foramen magnum and the opening for the 

 5th nerve cleaned. The cranial cavity is higher than wide. The basi- 

 occipital and basispheuoid are thick bones even in the middle line ; 

 and the basioccipital tubera lie considerably below the level of the
