Abstract

In this part twelve species are added to the New Zealand Recent fauna, and of these, three are new species, and ten are representative of genera not previously known in this faunal area—they are Casmaria, Dolabrifera, Fusinus, Liniaxis, Lyncina, Morula, Proxicharonia, Pteropurpura, Semele and Tutufa. All of the new additions are of tropical or subtropical origin, an element that has been greatly strengthened within recent years, largely due to the increased activity of skin divers, working in the previously unexplored depths of the off shore rocky areas. Regarding origins, the influence of the East Australian Current satisfactory accounts for the genera Dolabrifera, Fusinus and Liniaxis. There is a recent survivor from a characteristic New Zealand Miocene genus in Proxicharonia palmeri n.sp. The remaining genera, however, point to a tropical South Pacific origin, except for the Pteropurpura, which comes from Japanese seas. The most unexpected addition is Lyncina vitellus, the second species of a true cowry to the found living in New Zealand waters. The first true cowry to be found here, Erosaria cernica tomlini Schilder, 1930, was recorded in these records in 1965 (Powell, Rec. Auck. Inst. Mus., vol. 6, no. 2, pp. 164-165).
