Cranium E506 (Plates XII — XVI) shows the more usual formation. Here the 
profile shows an 'infantile' forehead rising vertically from the nasion. The line then 
curves backwards, and runs almost horizontally, with a slight indication of post- 
coronal depression, to a point in the mid-sagittal area. Beyond this it curves down 
to the lambda, and shows some occipital projection before curving in towards 
the base of the skull. The orbits and zygomatic arches are extremely lightly 
developed, but the mastoid processes are of fairly large size. The cranium shows 
metopism with an accompanying breadth of forehead, but there is a tendency 
towards the obliteration of all sutures. There are some very small ossicles in the 
lambdoid suture. None of the teeth have been preserved, but the alveolar margin 
is in good condition, and shows the sockets of the full complement of permanent 
teeth, including the wisdom teeth. This is the only specimen to which it has been 
possible to fit a mandible, and the mandible in this case shows a somewhat low and 
sloping ramus, a shallow sigmoid notch, and slight mental prominence. The three 
lower molar teeth on each side have been preserved. 
Plate XVII shows the above two crania in comparison with a typical adult male 
and female of normal size in the collection, the male being placed below the 
female in the plate. 
The other crania of small size under consideration show a formation more 
closely resembling E 506 ; and, of these, E 21 shows considerable absorption of the 
hinder portions of the alveolar margin, but appears to have had the wisdom teeth 
in position. The forehead here is however not vertical, as in the case of E 506, 
but slopes backwards somewhat from the nasion. 
E 420 shows no wisdom teeth, but the other molars in position are considerably 
ground down, and the sphenoid and occipital bones are united. This cranium is 
also metopic. 
E 579 shows the three upper molar teeth in position on the left side, on the 
right the second and third molars are wanting, and their sockets are somewhat 
absorbed. This cranium is rather larger than the others under consideration, and 
shows somewhat marked supraorbital ridges, and postcorooal depression. 
E666. Here five teeth are present, viz. the two bicuspids and the three 
molars of the right side ; and in association with the wisdom tooth is an accessory 
molar. The teeth are wanting on the left side. 
E 862 shows no wisdom teeth, and the other teeth present show no great signs 
of wear, but the spheno-occipital synchondrosis is obliterated, and the cranium 
appears to be that of a young adult. There is an epipteric bone (26 mm. 
long) on the left side. 
E 869 shows the sockets of both upper wisdom teeth. Slight supra-orbital 
ridges are present, and also a slight metopic crest, and postbregmatic eminence. 
E 919 also shows the sockets of both upper wisdom teeth, and though 
remarkably small has somewhat heavier mastoid processes than is usual among 
these small specimens.
