DICYNODON BOGERSI, sp. nov. 



Some years ago Dr. Rogers collected in the Thee Kloof, Nieuweveld, 

 C.P., an almost complete skull and lower jaw which was regarded as a 

 male specimen of D. Icolbei. Recent examination has, however, led us 

 to consider that it may well be taken as the type of a new species. 

 The skull is in a good state of preservation, and shows most of the 

 sutures of the top of the skull.
