3. Antipatharia
The Hexacoral group of Antipatharia has received but slight attention in Antarctic waters. The chief contributors have been Thomson
(1908), Thomson and Rennet (1931), and Pasternak (1961).
Thomson (1 908) described a new species Bathypathes bijda
from 71'22'5, 16'34'W. Thomson and Rennet (1931) recorded one
species Euuntipathes plana (Cooper) from off Macquarie Island and
Bathyplanes patula Brook from 64"34'S, in 3 109 m. Pasternak (1959)
recorded the discovery of further specimens of the cosmopolitan antipatharian Bathypathes patula off the Antarctic continent in depths of
4 636 and 4 200 m.
4. Octocorallia
The subclass Octocorallia is divided into the three orders, Alcyonaria,
Gorgonaria and Pennatularia.
Molander (1929) contributed a major report on the whole subclass
in his report on the collections of the Swedish Antarctic Expedition.
Most other authors have been concerned with one or other of the orders.
The Alcyonaria have been dealt with by Roule (1902, 1907,
1908), Hickson (1907), Kuekenthal (1906, 1912), Gravier (1913a,
b, c, d), Thomson and Rennet (1931) and Deichmann (1945).
Some of these authors mentioned above have also dealt with the
Pennatularia but the following workers have been concerned primarily
with this latter order : Jungersen (1907), Broch (1959) and Pasternak
(1962, 1961).
The Alcyonaria are not well represented in Antarctica, the only
species recorded apparently being Alcyonium antarcticum Wright and
Studer from East Antarctica (Molander, 1929), A . paessleri May from
the Antarctic Peninsula, A. clavatum (Pfeffer) from South Georgia and
the Falklands, and Conulariella antarctica Gravier from the Antarctic
continent and from South Georgia. Alcyonium antarcticum is also
widely distributed in the Subantarctic and A . paessleri has also been
recorded from Tierra del Fuego and from off South Africa. Eunephthya
armata is known only from East Antarctica.
The Gorgonaria are quite strongly represented but the recorded
distribution patterns seem so patchy that little in the nature of zoogeographical conclusions can be drawn from the group. A few species
are known from both East and West Antarctica, e.g. Primnoella antarctica Kukenthal and Thouarella variabilis Wright and Studer, a few
are confined to West Antarctica and the Antarctic Peninsula, perhaps
also extending to South Georgia and the Magellan region. The general
