DlCYNODON PTGMAEUS, sp. 11OV. 



This is one of the smallest known species of Dicynodon. As two or 

 three specimens were obtained from the same locality of about similar 

 size, it seems probable that the specimen represents a small species 

 rather than a young individual. 



The species is characterised by the relatively great width of the 

 anterior ends of the parietals, which causes the preparietal region to 

 be nearly twice as wide as the frontal. 



The frontals are large, and extend well back by the sides of the 

 preparietal. The postfrontals are very slender. The postorbitals are 

 large, the posterior portions being broad and rather flat. The 

 squauiosals are relatively less developed than in most species.
