and rests behind on the posterior border of the foramen magnum. The 
basibregmatic height is less than the breadth, and the vertical index is 
76*8. 
Manx; borders of Jalor and Rhaman (Plate XVI, figs. 4, 5, 6), 
It is not certain that the Mam tribe is absolutely identical with the one 
we have described under the name Hami ; but its headquarters do not lie 
more than twenty-five miles distant, as the track leads, from the headquarters 
of the Hami. It is represented in our collection by a calvaria, from the 
Rhaman side of the border, and by a fairly complete skeleton from a cave on 
the Jalor side. The calvaria we found ourselves ; it was lying on the ground 
in a depression at the base of a limestone cliff, distant about two miles from 
Ban Kassot (antea y p. 8). The Siamese Nai-ban , or headman, of this village 
told us that it was the skull of a Semang man in middle life, who had fallen 
from a tree while collecting honey and had subsequently died of c fever,’ his 
relatives having taken him to the base of the cliff for shelter. 
The skeleton was obtained by the mor y or medicine-man, of the same 
village, and was proved to be that of a Semang, not only by the position in 
which it was found, but also by the character of the hair-—a considerable 
quantity of which remained. The extraordinary state of preservation of the 
body has already been noted ; it did not appear to be due to any fungoid 
growth, and was the more remarkable, seeing that the caves of Jalor are 
generally very damp. 
Skulls. The more perfect of the two skulls, No. 3, is that of a person tn 
the prime of life, and is certainly female ; while the calvaria, No. 2, exhibits 
rather ill-defined male characteristics, and appears, judging from the condition 
of the sutures, to represent a somewhat older individual. 
Norma verticalis . Both skulls are nearly oval in outline, but No. 2 has 
the central part of the parietal region very prominent on either side. No. 3 
is mesaticephalic, and No. 2 just dolichocephalic, their respective indices 
being 7 ^‘5 anc ^ 75 ‘ 0 . The slope of the post-parietal region in both is 
gradual, and the side walls of the cranium are almost vertical. In No. 2 there 
is a well-defined sagittal ridge and the vault of the cranium is roof-shaped, but 
that of No. 3 is fairly well rounded. In the latter skull there is a long narrow 
depression, embracing the posterior portion of the sagittal suture, but there is 
no depression or marked flattening of the kind in this part of the male calvaria. 
In both specimens the parietal longitudinal arc is relatively short. 
Norma lateralis . In No. 3 prognathism is present but not excessive ; the 
nasal bones are relatively flat, and the nasion is little depressed. The forehead
