I now come to consider more in detail the series of measurements given [below]. In this series, which ranges from 69·2 to 86·2, there is a want of uniformity arising from the fact that the numbers tend to gather together around three centres, one between the indices 75 and 76, another between the indices 80 and 81, and the third between the indices 82 and 83. We have thus in this series of a hundred indices, obtained by measurement of the head of the living subject, evidence of different prevailing types of skull amongst the natives of the Solomon Group; and it will be subsequently shown that each locality has usually one prevailing type.

(1) St. Christoval and the adjoining islands of Ugi, Santa Anna, and Santa Catalina. As shown in the subjoined [table], this series of 35 indices has a wide range between 69·2 and 86·2. The value of the median index of the series is 75·9; and the average of the numbers is 76·6. Out of the 35 indices, 11 are included between 74 and 76. On the whole, however, I should take 76 as representing the average cephalic index in this part of the group, although even here, as shown in the series, there is some disturbing element.

(2.) The Islands of Bougainville Straits, which include Treasury Island, the Shortland Island, Faro Islands, and the western extremity of Choiseul.

The range of the subjoined forty indices is 75·9 to 85·2. The contrast between this and the preceding St. Christoval series, as shown in the grouping in the indices, well illustrates the prevalence of distinct types in these two regions of the group. The indices of greatest frequency are included between 80 and 81: the average of the figures is 80·6, and the value of the median index is 80·7, which may be accepted as the typical index.

(3.) The North Coast of Malaita.—Through the kindness of the Hon. Curzon-Howe, government-agent of the labour schooner “Lavina,” I was enabled to measure ten natives who had been recruited from the districts of Urasi and the Uta Pass on the north coast of Malaita.
