Fauna and Stratigraphy of the Stormberg Series. 361 



The lateral temporal opening was long and fairly low. In it can 

 be seen a portion of the quadrato-jugal, lacking the outer edge, and 

 articulating with the quadrate. 



The supraoccipital articulates above with the parietal in a fairly 

 long suture. Ventrally it narrows rapidly and articulates on its 

 oblique edges with the exoccipitals, which are apparently large bones. 



The weathering away of the bone shows a canal opening into the 

 auditory region between the quadrate and the parietal on the posterior 

 border of the upper temporal opening, and this is continued into the 

 post-temporal vacuity, bounded by the squamosal and parietal above 

 and the exoccipital and supraoccipital below. 



Mandible. Part of the lower jaw is preserved. The symphvsis is 

 fairly short, and formed apparently wholly by the dentaries. The 

 lower jaw is slender, its deepest part being just behind the Meckelian 

 cavity. 



Of the right rainus, the dentary is wholly preserved. It meets its 

 neighbour in a symphvsis I'J mm. long. The alveolar border is 

 straight and carries about 12 teeth of which 9 can be seen. The 

 first two are in the position of incisors and point strongly forwards. 

 The third is considerably larger than any of the others. Posterior 

 to it the teeth seem to be of approximately equal size to one another. 

 At the level of the last three or four teeth the dentary is extremely 

 shallow, while it broadens again towards the Meckelian cavity, of 

 which it forms the anterior half of the border. The ventral face of 

 the symphysial region is convex from side to side, and pitted. 



The splenials are not preserved; but the shape of the inner 

 surface of the right dentary shows their approximate positions. The 

 bone did not enter the symphvsis. For over one-half its length it 



/ i / o 



lay along the inside of the dentary. For a distance of 18 mm. it 

 was separated from the dentary by the angular, lying along the 

 inner surface of that bone almost to the level of the outer fossa. 



The angular has relations with the other bones, as far as can be 

 seen, similar to those in the Crocodilia. It forms the posterior border 

 of the outer fossa, and passes on the ventral side below the dentary, 

 separating it from the splenial. None of the other bones are seen. 



Scapula. The right scapula is displayed in full, as well as the 

 glenoid end of the left scapula. The bone is extraordinarily expanded 

 at its upper end, and somewhat swollen below. The posterior border 

 from the narrowest part of the bone upwards is almost straight, 

 save at the upper extremity; but the anterior edge is strongly 

 bent owing to the anterior prolongation of the upper part of the 

 bone. The lower part of its anterior border is swollen and convex,
