Skull (fig. 4). — Brain-case only very slightly deflected, the 

 alveolar line if continued backward passing below, or through, the 

 lower margin of the occipital condyle. Occipital and hinder parietal 

 region considerably more flattened than in any other species of the 

 genus, supraoccipital much lower, outline of lambdoid crest, in back 

 view, therefore more flatly convex. Owing to the combined eff"ect of 

 the slight deflection of the basicranial .axis and the flattening of the

occiput, this latter portion of the skull is directed more backward, 

 less obliquely downward, than in other species. Premaxillaries 

 firmly co-ossified in front, forming an unbroken bar without any 

 trace of a median suture, even in slightly immature individuals ; 

 ascending rami of premaxillaries slenderer than in other species, 

 particularly in their up])er half. .Supraorbital margin and bases of 

 postorbital processes more raised above the le\cl of the upper surface 

 of the skull, making the frontal plateau between the processes very 

 distinctly concave from side to side. Palation border and meso- 

 ptei'vgoid fossa rather narrower than usual.
