is long. The parietal bar is short, and the postorbitals almost meet 

 behind the pineal foramen. The postf rental forms a long part of the 

 orbital border, stretching outwards along the postorbital bar ; but it 

 narrows rapidly posteriorly and does not reach the level of the pineal 

 foramen. 



The snout is short, and the caniniform process is well forward below 

 the nostril. The nostrils are close together and look forwards and 

 outwards.

This species has a remarkably short and narrow palate compared 

 with the width between the jugal arches. The tusks pass downwards 

 below the front of the orbit ; but seen from in front the edges of the 

 caniniform pi'ocesses curve inwards, so that the width between the 

 tusks is small. 



The occipital condyle is tripartite and short, The foramen jugulare 

 lies at the level of the top of the condyle and looks backwards. The 

 paroccipital process is very stout, especially laterally, and its lower 

 border is strongly concave. The basisphenoidal tubera are not espe- 

 cially prominent, but lie well below the condyle. The quadrates 

 set close together.

DlCYNODON GRANDIS, Sp. UOV. 



A complete skull and lower jaw obtained on the farm Dunedin, 

 Beaufort West, C.P. (S.A. Mus. Cat. No. 2679), seems to belong to a 

 new species. It is somewhat crushed laterally, and the sutures do not 

 show very cleaiiy the specimen being presumably an old individual.
