is the tabulare. It is a large membrane bone lying behind the 

 squamosal almost for the whole length of the posterior border of the 

 temporal fossa, being thickest at its lowest end. It forms the larger 

 part of the occipital plate lying above the condyle. 



The squamosal forms but little of the occipital plate, the par- 

 occipital extending almost to the border. In other Dinocephalians 

 the squamosal enters largely into the composition of the occipital 

 aspect. 



The condyle is large, single and rounded. 



The palatal view is similar to that of Tapinocephalus. The basi- 

 occipital is a large bone. The pterygoids are separated by a long 

 median groove. The stapes articulates with the basioccipital and 

 the pterygoid.
