The limits of the lachrymal and prefrontal are not well displayed 

 in either of the two skulls we possess ; the lachrymal is certainly 

 small, but the prefrontal forms a large part of the inner orbital wall. 

 The lachrymal foramen lies wholly within the orbit. 



The frontal is broad and flat, forming the posterior half of the 

 supraorbital border. It has a short process passing back along 

 the side of the parietal, between that bone and the postorbital. 

 There is no postfrontal. 



The postorbital at its lower end rests on the jugal ; it forms the 

 whole of the postorbital bar and meets the parietal, forming part 

 of the inner border of the temporal fossa. 



The pineal foramen is placed in a distinct depression. I am 

 inclined to believe that it is wholly surrounded by the parietals, 

 the preparietal being absent.

The parietal crest is high and narrow. Posteriorly the parietals 

 are separated by a deep groove which has a shallow prolongation on 

 to the upper half of the occipital plate. 



The occipital plate is peculiar. The lower two-thirds is vertical ; 

 but the interparietal and the upper halves of the squamosal parts 

 are bent at an angle of between 110 and 120, so that the plate 

 is completely hidden from view both from above and from the sides. 

 The bones of the occiput occupy the same relative positions as in 

 other members of the Anomodontia. The foramen magnum is large. 

 The exoccipital has, on the inner border midway between the 

 condyle and the supraoccipital, a prominent protuberance, and 

 external to that another smaller rugose knob ; the posterior corner 

 of the paroccipital is prolonged to form a bluntly pointed process. 

 The lateral occipital foramen is large, lying mostly in the exoccipital,
