not ridged in the sagittal line, and the slope outwards to the parie- 
tal eminences was not steep. In most of the crania the greatest 
width was in the parietal region, near the eminences, and the 
sides of the crania were almost vertical below these projections. 
The skull was not flattened in the parieto-occipital region, except 
in one specimen, in which the length-breadth index was 77T. In 
the nine other crania the index ranged from 68 to 75*7, so that the 
crania were of the dolichocephalic character, and the mean of the 
entire series was 7 2 ‘6. In five crania the height exceeded the breadth, 
in one these diameters were equal, in four the breadth somewhat 
exceeded the height; the mean vertical index was 73*8. In all 
the crania, with one exception, the parietal longitudinal arc was 
longer than either the frontal or occipital. In the dolichocephalic 
form and proportions, in the height being frequently greater than 
the breadth, and in the dominancy of the parietal longitudinal arc, 
the skulls possessed Melanesian characters. 
The norma facialis showed in the male skulls a moderately pro- 
jecting glabella and supra-orbital ridges, a forehead not specially 
retreating, no great depression at the nasion, nasal bones moder- 
ately projecting with the osseous bridge concave, anterior nares 
moderately wide and with a mean nasal index 50. The nasal 
process of the superior maxillse was moderate ; the floor of the nose 
was continued into the incisive region of the upper jaw without the 
intervention of a sharp ridge, except in the skull with the higher 
cephalic index (No. 2 in Table I.), in which also the jaw was 
orthognathic; in almost all the other crania the upper jaw was 
distinctly prognathic, and the mean gnathic index was 104*7. The 
width of the orbit did not, as a rule, greatly preponderate over the 
height, and the mean index 86 was mesoseme. In several skulls 
the palato-alveolar arch was proportionately long and the mean 
index was 110*6, just above the dolichuranic group. As regards 
the proportion of the face generally, obtained by taking the pro- 
portion of the interzygomatic breadth to the nasio-mental length, 
the mean complete facial index was 84*1, which places them in the 
chamseprosopic or low-faced group of Kollmann. 
The cubic capacities were measured by my assistant, Mr James 
Simpson, in accordance with the method which I recommended in 
my Report on the Human Crania ( Challenger Rppoiis, Part XXIX.,
