Total head length for all Fijians is 187.9 mm; longest heads occur in the interior. Both Howells' Fijian average and the Solomon Islands series are close to the above value. Gifford's Tongan head length of 191 mm. Somewhat exceeds the Fijian.

General head breadth is 155.9 mm., and considerable regional variation is shown. Fijians of the interior have the narrowest heads, whereas the coastal and eastern people have appreciably wider heads. Howells' series of Fijians are closest to my highland groups.
The Solomon Islanders are markedly narrower headed than the Fijians, whereas Sullivan's Tongan series is nearer the Fijian average.

Most Fijians tend to brachycephaly. The eastern natives and those of the coastal series have the broadest heads. The interior people show definitely lesser values in this ratio than do the other groups. Howells' Fijian series is close to the northwestern Fijians in their mesocephaly, and so is the Tongan mean. The Solomon series borders on dolicocephaly.
