210 REVISTA CHILENA DE HISTORIA NATURAL 
The bulging of the lower portions of the parietals and of the 
squamose portions of the temporals is very pronounced; as is also 
the arching of the zygomata. The temporal crest is not noticeable 
except in the frontal. The upper portion of the coronal suture 
is depressed which causes a corresponding bulging, anterior and 
posterior to the bregma. The frontal also bulges over the central 
line; but flattens away over each orbit. 
The parietal eminences cannot he precisely designated owing 
to the rounding curves of this part. 
Different to the other skulls, the maximum breadth is not 
found in the bi-parietal diameter, but in the temporal region, 
20 mm below the squamose edge. 
The skull is not symetrical, one parietal being higher Th 
the other, while the right side of the occipital protr udes 10 mm 
more than the left. Below the inion there are two deep impres- 
sions, where the recto-mayor muscles were inserted. The mastoids 
are small and pointed, the digastric grooves aay wide, and the 
condyles insignificant. The palate i is V shaped, long and narrow; 
the teeth worn even more than in A; forming a sharp cutting 
edge on the outslde, and worn dawn to 5 alveolars on de 
inside. The lower jaw is wanting but must have been narrow 
and pointed. 
This skull is the most chameocephalic of the whole series 
although it is well within the limits of orthocephaly, with an 
index of 71. 2 
As I have already mentioned; the skeleton to which this skull 
belonged was found buried together with she skeletons, of two 
children, one of añ infant, and the other evidently not more than 
four years old. But the bones were in such a fragmentary 
condition that it was impossible to take any measurements or 
even to make any detailed study. 
Skull. B. 
On examining this skull the theory of the American anthro- 
pologists, as to the probability of the primitive inhabitants of 
this continent having been of the Eskimo type immediate 
(omision) by ocurred to me. Here we have many of its peculia- 
rities reproduced, although in some cases slightly modified. The 
Fuegians also, if one allows for distance and Aló circumstan- 
ces are in many respects very similar. 
In this skull we have the dolichocephaliy (75.68), the marked 
scaphoid character without any sign of synostosis, the infra— 
orbital sutures, the massive nature of the body of the mandible, 
the wide palate and worn teeth, the flat face with its prominent 
malars, the considerable sub-nasal prognathism, the prominense
