with the parietals and a somewhat narrower oblique suture 

 with the supraoccipital. The parietals are ol: relatively 

 large size and of subquadrate form, considerably longer tlian 

 broad. They are rather widely separated from the^ margin 

 of the skull, except at the antero-lateral angle, by the 

 greatly enlarged and inflated pterotics. The sphenotics are 

 not visible in this view. The epiotics are well developed, 

 but rather narrow, and a comparatively large triangular

process of the exocciptal is visible from above and runs 

 forwards for at least two-thirds of the distance from 

 the posterior margin of the skull to the antero-central 

 angle of the epiotic. The supraoccipital is very large and 

 is separated into two distinct regions — a subcircular anterior 

 region, contained between frontals and the anterior half of 

 the parietals, and a posterior vase-shaped region of about 

 three times the length of the anterior part and occupying 

 a little more than a third the breadth of the skull. The 

 inflation of the periotic capsules gives the posterior region
