In addition to the bones described above, the specimen as collected 

 comprises a number of ventral ribs and a large part, perhaps the 

 larger part, of the skull. The latter, however, is badly shattered 

 from exposure, and will require much patient 

 labor to restore it. In much probability other 

 bones of the skeleton remain to be excavated, 

 and it is hoped to secure them the coming sum- 

 mer. 



The specimen was discovered by Mr. Roy 

 Moodie and Mr. E. E. Ball. 



What the relations of this animal are it is 

 at present impossible to say, other than it 

 probably belongs to the early rhynchocephaloid 

 type, or in the super-order Diaptosauria of 

 Osborn. I can find nothing in the literature, 

 of either the Permian or Triassic reptiles of 

 Europe or America, which approaches it. The 

 structure of the girdle, the shape of the hume- 

 rus, and its mode of articulation indicate a 

 swift-moving crawling reptile of considerable 

 size. The skull will doubtless throw much
