| Abstract |
New Zealand Oceanographic Institute collections from the area include seven genera and seven species of echinoids and eight genera and nine species of holothurians. In the latter group is a new species of the genus Placothuria Pawson and Fell, 1965. New records are the echinoid genera Brisaster and Austrocidaris. The known echinozoan fauna of the southern islands of New Zealand now comprises 13 genera and 15 species. The fauna shows a strong affinity with that of New Zealand. Six species are now known from Macquarie Island, and close relationships between Macquarie Island fauna and that of New Zealand are evident. Though the west-wind-drift has apparently contributed no external elements at the species level to the present-day fauna of the southern islands, it has probably functioned as an effective agent in establishing continuity in the faunas of the individual islands. The fauna of the Chatham Islands is closely related to that of Cook Strait, New Zealand, but is markedly dissimilar to that of the southern islands of New Zealand. The Chatham Rise bathyal echinozoan fauna has a cosmopolitan to Indo - west-Pacific facies. |
