79.1, 72*9. The post-parietal slope is very gradual in No. 8, only moderately 
so in No. 9, and in No. 10, intermediate. The vault of the cranium is flat in 
No. 9, decidedly roof-shaped in No. 8, and rather less so in No. 10 ; in No. 8 
there is a definite sagittal ridge. The side walls of the cranium are almost 
vertical in No. 8, somewhat convex in Nos. 9 and 10. The depression in the 
post-parietal region, noted in several of our skulls, is absent in Nos. 8 and io, 
and is represented by a local flattening in No. 9. In Nos. 8 and 10 the frontal 
longitudinal arc is slightly longer than the parietal, and the reverse is the case 
in No. 9. 
Norma lateralis. Prognathism is present, but not excessive, in Nos. 8 and 9. 
The external nares are wide, and the nasal bones flat, but these characters, 
which are very marked in No. 9, are less pronounced in No. 8 than in any 
other of our Sakai or Semang specimens. The glabella and superciliary ridges 
are not prominent in any of the three specimens, and the forehead is fairly 
vertical in Nos. 9 and 10, but low and retreating in No. 8. The outline is 
very flat in Nos. 8 and 9, somewhat arched in No. 10. The occipital squama 
is convex, forming a boss ; the cerebellar part of the occiput is moderate in 
dimensions in Nos. 8 and 10, somewhat larger in No. 9. The mastoids are 
fairly stout in Nos. 8 and 9, somewhat feeble in No. 10. The zygomata are 
comparatively stout in No. 8, slender in No. 9. 
Norma facialis. The face is broad and very flat in No. 9, the maxillo- 
facial index being only 41 ; in No. 8 it is much longer and narrower and 
somewhat more arched, the same index being 48*1, while the complete facial 
index, which could not be taken in No. 9 on account of atrophy of the lower 
jaw, is 89*8. The nasal index in No. 8 is only mesorhine, 50”Q, but in 
No. 9. it is hyperplatyrhine, 68 - I. The orbital indices of Nos. 8 and 9 
are 84-2 and 8l 'I, respectively. 
Norma occipitalis. The outline is oval in No. 8, fairly circular in Nos. 9 
and 10. The conceptacula cerebelli are fairly prominent in No. 10, but less 
so in the other specimens. 
Sutures. In all three specimens the sutures are fairly simple and have 
remained unossified, in spite of the great age indicated by the condition of the 
jaws in No. 9. This is the only metopic specimen in the collection. In No. 
8 there are two small Wormian bones in the right lambdoid suture, and one 
each in the left lambdoid and the asteria. The conditions in No. 10 are 
somewhat similar. 
Jaws and Teeth. The lower jaw is present in all three specimens ; but 
in No. 9 it has become completely edentulous through age, even the alveolar 
border having been absorbed, while in No. 10 it is somewhat broken. In No. 8
