{Recent subantarcitc benthic ostracod faunas from the Marion and Price Edward Islands Archipelago, Southern Ocean}

Twenty-seven sea-floor samples from a depth range of 32-474 m around Marion Island in the Southern Ocean, mid-way between southern Africa and Antarctica, yielded fifty-nine species of benthic ostracods in at least thirty-six genera. This compares with twelve species which were collected from the Prince Edward Islands archipelago during the HMS Challenger expedition in 1874 (Brady, 1880). Zonation in the ostracod faunas can be related to changes with depth in the type and distribution of sea-floor benthos. The endemic nature of the fauna is reflected in the probability that thirtyfour of the species are new. Five of these are formally described: Dutoitella lesleyae, Hem icy the ru ra branchae, Munseyella bissetae, Poseidonamicus whatleyi, and Rabilimis? marionensis.
