forms nearly the whole of the front of the roof of the mouth. No 

 septomaxilla showing on face. Nostrils well advanced, large. Cauini- 

 forin process just behind plane of back of nostril. 



Through the courtesy of the Director of the Port Elizabeth Museum 

 I have been enabled to see the type. It is an unsatisfactory specimen, 

 and its chief interest lies in the fact that it was probably obtained 

 from a locality from which very few Dicynodont or other reptilian 

 remains are known. 



Type in the Port Elizabeth Museum. 



Locality. Probably Hanover, C.P. 



Horizon. Lower Beaufort Beds. (Zone of Endothiodon or of Ciste-

Skull of medium size, as broad as long. Snout very broad, pre- 

 orbital region very short. Beak short, nostrils small. Above nostrils, 

 nasals form two prominent knobs which pass forward well in front of 

 premaxilla. Frontal region flat and broad. Interorbital width : inter- 

 temporal width : : 9 : 4. Preparietal large, postf rout als entirely hidden. 

 Postorbitals meet behind the pineal foramen.

This species is one of the largest of the Dicynodous. The original 

 description is as follows : " The snout is narrow and deep and the 

 nostrils large. The orbits are placed near the middle of the head. 

 The postorbital arch is powerful. The parietal region is broad, and 

 the posterior ranius of the postorbitals unusually well developed. The 

 pineal foramen is situated well behind the postorbital arch. Behind 

 and on about two-fifths of each side it is bordered bv the parietals.

The rest of the foramen is bordered by the large preparietal. The 

 frontals extend back on each side of the preparietal to nearly the 

 plane of the back of the foramen. The postfrontals are moderately 

 large."
