Viewed from above (Fig. 1) the sutures are seen to be obliterated (except the 
lambdoidal suture, which is faintly indicated on the left side). The parietal 
region is symmetrically vaulted. In each parietal bone at its posterior 
superior angle is a large perforation, symmetrically placed, and separated in 
the middle line by a bridge of bone without sutures, 20 mm. broad at the 
narrowest part. The /¢ft perforation reaches the lambdoidal suture, which is 
faintly marked in the surface of the skull. It is oval in outline, and

measures 4:0 cm. antero-posteriorly : 3-2 cm. from side to side. The right 
perforation is smaller and more circular, and does not extend so far forwards 
or backwards. _ It measures 3:0 cm. from before backwards; 3:2 em. from 
side to side. The margins of both holes are bevelled externally, and (to a 
less extent) internally, and the outer surface of each is marked by numerous 
diverging striations. 
A front view of the cranium (Fig. 2) shows the exaggerated vault of the 
frontal bone, temporal ridges well marked, and curved in such a way as to 
narrow the forehead to a remarkable degree (62 mm.); prominent external 
angular processes, and well marked but small supra-orbital arches. The 
frontal bone is flattened in its lowest part, and becomes vaulted above. In 
its centre is a prominent ridge, running upwards as far as the bregma. The 
supraciliary ridges are faintly indicated. About 25 mm. from the glabella on 
the left side of the middle line is a small round hole communicating with the 
left frontal sinus. It appears to have been formed during life, as attached 
on each side of it is a small irregular spicule of bone. 
A side view (Fig. 3) shows the remarkable expansion of the parietal and 
occipital regions as compared with the frontal and temporal regions. The 
slope of the frontal bone is well marked; the temporal fossa is small and 
shallow, and the root of the zygoma is separated from the external angular 
process of the frontal bone by a distance of only 40 mm. The temporal
