FASCICULI MALATENSES 
The mandible is not visible from above in either. The cranial vault is 
flattened, especially in No. 23. The parietal longitudinal arc is the longest 
of the three in No. 24, while the frontal is the longest in No. 23; in both 
cases the occipital arc is considerably shorter than either the frontal or the 
parietal. Only a very small proportion of the post-parietal slope is visible 
from above in the male specimen, but in the female skull a point some 
millimetres below the lambda is within the plane of vision. There are 
no marked local depressions upon the surface of either skulk The cephalic 
index of No. 23 is 87*2, that of No. 24, 78-7. 
Nonna lateralis , 
The posterior termination of the cranium approaches the condition 
described in the Malay skull from Jambu (No. 21), but the abruptness of its 
slope is not quite so excessive ; in the female specimen the slope is that of a 
normal sub-brachycephalic skull and the occipital squama is decidedly convex 
outwards ; in both, the angle between the plane of the squama and that of 
the nuchal part of the bone is wide. The longitudinal arc of both crania is 
inclined to flatness above ; the forehead is fairly vertical in the female 
specimen, low and retreating in the male. Though the supra-orbital ridges 
are well developed in the latter, they do not jut out from the base of the 
forehead, but emerge from it gradually. The nasion is not much depressed ; 
the nasal bones are moderately prominent, being slightly recurved at their 
inferior extremity m the female skull. Prognathism is quite absent, the gnathic 
indices of the male and female skulls being respectively 95*2 and 94. The 
zygomata are stout and expanded, especially in the male skull ; but the 
mastoids are only moderately strong. The skulls rest behind on the posterior 
border of the foramen magnum, which is very large in No. 23 ; but the 
plane of the foramen approximates to the horizontal. The left styloid 
process of No. 24 measures 26 mm,; the right, 19 mm. The height of the 
cranium is, in both cases, less than the breadth, and in the male skull the 
difference between the two measurements is very marked ; the vertical indices 
are 78*4 and 77*5, and the height indices 90 and 98*5. Exactly how far this 
condition is correlated with what appears to be artificial distortion in the male 
cranium, it is impossible to say. 
Norma facialis . 
The orbits are mesoseme in No, 23 and microseme in No. 24, the two 
orbital indices being 87*8 and 80. The nasal aperture in No. 24 is cordiform, 
while in No. 23 it is rather longer and narrower ; the floor of the nasal cavity
