Forty-three species are recorded from nine samples collected during the Sir Peter Scott Expedition to the Pitcairn Islands. Only one sample was from Pitcairn Island, one from Oeno Atoll and 7 from Henderson Island. All but one of the 43 species occurs at Henderson Island, 9 at Pitcairn Island, but only 2 at Oeno Atoll. Twenty-six (60.5%) of the species are endemic, being confined to the Pitcairn group; 9 species (21%) occur only in the Pitcairns and at Easter Island; 2 (5%) species also occur elsewhere in the Indo-Pacific and at Easter Island and another 2 species also occur elsewhere in the Indo-Pacific but not at Easter Island. Four of the species belong to those species that are virtually pandemic throughout global tropical seas. Of those 26 species confined to the Pitcairn Group, 9 are new as is one genus. These are: Neonesidea apostasis sp. nov., Neonesidea blighi sp. nov., Thesceloscythere labyrinthos gen. et sp. nov., Loxoconcha dictyoklostos sp. nov., Loxoconcha hendersonislandensis sp. nov., Tenedocythere apios sp. nov., Tenedocythere stasiotes sp. nov., Xestoleberis macrocicatricosa sp. nov., and Xestoleberis macrorrhinos sp. nov. The remaining 17 species are left in open nomenclature. Despite the great oceanic distances that separate the two areas, the Pitcairn Group fauna clearly indicate closest affinities with Easter Island, rather than with that of islands much nearer to the NW.
