FASCICULI MALATENSES 
The two skulls present great differences, and I have thought it best to 
describe them separately, although it is quite possible, indeed probable, that 
their diversity is not due to a difference in geographical origin ; for it is evident 
that they are extreme examples of two different types of head which we know 
to occur together in the Fatani States, 
Skull No. 21, Jambu Malay . 
Though the skull is fairly heavy, its smooth outlines, the prominence of 
its frontal eminences and its vertical forehead give it a somewhat feminine 
aspect, with which its low cubic capacity (1,330 c.cm.) agrees; but the structure 
of the rest of the skeleton and its history prove it male. Synostosis has com¬ 
menced in the coronal sutures in both tables of the bone and also at several 
other points, indicating that the individual had past his first youth, and I do 
not think that the absence of any external trace of the third molars in the 
lower jaw and on the left side of the upper jaw can, in this case, be taken as 
indicative of youth. 
The lower jaw from the same locality also appears, judging from its size 
and from the muscular impressions, to have belonged to an adult male. 
Notma verticalis. 
The skull, in this aspect, approaches the square in outline, but is very 
asymmetrical, the whole of the left side of the cranial box and also, to a lesser 
extent, of the face having been pushed forward in front of the right half. 
The skull is cryptozygous, although it closely approaches the phaenozygous 
condition. Though it does not exhibit numerical prognathism as defined by 
Flower, the protrusion of the mandible beyond the line of the face is very 
conspicuous from above ; but, as Sir William Turner 1 has recently pointed 
out, in skulls in which the nasion is much depressed below the level of the 
forehead, as is the case in this specimen, Flower's gnathic, or * alveolar,' index 
does not give an altogether true indication of the degree to which prognathism 
is present. The cranial vault is flat, and shows no tendency to be roof-shaped. 
The parietal longitudinal arc is considerably longer than either the frontal or 
the occipital. The side walls of the cranium are almost vertical, and only a 
very small proportion of the post-parietal slope is visible from above. The 
frontal region is well developed, and there is no marked protrusion of the 
parietal on either side. There is little indication of the longitudinal post- 
parietal depression so common in the crania of the wild tribes of the Malay 
Peninsula, but a band-shaped depression, more noticeable on the left side than 
on the right, runs across the skull behind the coronal suture. The cephalic 
index is 85*9 ; decidedly brachycephalic.
