DlCYNODON COESTORPHINEI, Sp. nov. 



A small skull and lower jaw collected by the Eev. J. H. Whaits at 

 Graaff Eeiuet (S.A. Mus. Cat., No. 3337) seems to belong to an 

 uudescribed species, although in general appearance it partakes some- 

 what of the nature of Dicynodon lutriceps. 



The most noteworthy characters are the shortness of the beak, the 

 shape of the postfrontal, and the position of the pineal foramen. The 

 skull is depressed. The intertemporal bar is wider than the inter- 

 orbital region. The orbit is fairly large, looking more upwards than 

 outwards. The postfrontal extends outwards along the postorbital 

 bar somewhat in the manner seen in Eocyclops longus. The preparietal 

 is long and forms the anterior border of the pineal foramen, which is 

 very far back half way along the fairly long parietal bar. The 

 portions of the parietals behind the foramen are thus short and broad, 

 overlapped for more than half their width by the postorbitals and 

 truncated posteriorly by the interparietal. The iuterparietal in its 

 upper portion has a strong median ridge. The occipital condyle is of 

 the tripartite type. 



The specimen is tuskless.
