Platyrrhini is the rule in Fiji, but individual and regional variations are great. There are some leptorrine subjects in every province, and there are some whose noses are broader than long. The interior people and the northwestern groups have the relatively broadest noses, whereas the eastern index is more moderate. The noses of Sullivan's Tongans are relatively longer than the Lauans. The Solomon Island average is identical with the Fijian.
