Norma lateralis. 
The most remarkable feature of the skull in this view is its abrupt posterior 
termination. The post-parietal slope commences about midway between the 
bregma and the lambda and is gradual from its anterior commencement as far 
as the obelion ; from the level of the parietal foramina as far as the inion it is 
almost a vertical straight line. The plane of the nuchal part of the occipital bone 
also approaches the vertical, forming a very wide angle with that of the squama. 
The squama itself is quite flat, the external protuberance has a splayed or 
flattened appearance, and the cerebellar part of the occiput is relatively of small 
extent, exhibiting no outward convexity. The longitudinal arc of the cranium 
is moderately flat above ; the nasion is considerably depressed ; the nasal bones 
are not very prominent (though far from being so flat as in the case of several 
of the skulls described in a former part of this paper), and there is a marked 
prognathism (though the gnathic index does not quite reach 103), associated 
with a low angle of the entire face and not altogether subnasal. The zygomata 
are moderately stout, but the mastoid is very feebly developed. The skull 
rests behind on the posterior border of the foramen magnum, but the con¬ 
dyles very nearly touch the surface. The height of the cranium is slightly less 
than the breadth, the vertical index being 85*2 ; the height index obtained 
from Sir William Turner's formula, 
Easi-bregmatic height x 100 
Parieto-squamosal breadth 
is 99*3, 
Norma facialis. 
As already indicated, the forehead is high and vertical and the glabella 
and supraorbital ridges are feebly developed. The orbits are microseme, the 
orbital index being 8n. The nasal bones are long and rather narrow ; the 
nasal cavity is cordiform, being divided from the mandible below by a well- 
defined ridge, as in the higher types of human crania. The nasal index is only 
45-8, that is to say, leptorhine. The complete facial index is 83*8, and the 
maxillo-facial index 50-7, so that, taking Kollman’s definitions, the skull is 
chamaeoprosopic considered as a whole but leptoprosopic if the lower jaw be 
left out of account, the body of this bone being rather slight and the teeth of 
no great vertical length. 
Norma occipitalis. 
The outline of the skull is pentagonal from behind. The surface seen m 
this view is nearly flat and the opisthion is almost within the plane of vision, 
the foramen magnum, which is of medium size, being directed almost vertically
