Alcithoe aillaudorum n. sp. is the first Alcithoe known outside New Zealand waters ; it is however not considered a Gondwanian vicariant relict but is probably a recent immigrant that dispersed from New Zealand to New Caledonia via the Norfolk ridge. Lyria exorata n. sp. is known from Capel and Kelso Banks, two submerged flat plateaus surrounded by abyssal depths in the Coral Sea. L. habei Okutani, 1979 is a new record for New Caledonia. Records of other Lyria are reviewed and summarized. Although the distribution of Lyria in the Western Pacific corresponds rather well with the limits of the Pacific plate, this distribution appears to be a result of constraints in larval biology rather than a reflection of the plate tectonic history of the area.
