more extensive dermo-ossification of the post-orbital 

 region, which forms a complete roof over the prootic, 

 only the posterior portion of the latter being visible 

 from above. This roof, which completely closes the 

 orbit behind, is formed by the fronto-parietal and the 

 squamosal ; the latter bone has a convex posterior 

 border, separated from the likewise curved posterior 

 border of the fronto-parietal plate by a notch, the 

 angle of which corresponds to the suture between the 

 two bones.
