| Preliminary report on Cephalodiscus (Pterobranchia) from Admiralty Bay, King George Island, South Shetland Islands (West Antarctica) A. Urbanek and K. Zielinski Bulletin de l'Academie Polonaise des Sciences, Serie des sciences biologiques 1981, 31, 5/6, 257-262 |
Two species of pterobranchs, namely Cephalodiscus (Cephalodiscus) hodgsoni Ridewood and
C. (Orthoecus) solidus Andersson were found in 1979 by the Third Antarctic Expedition of the
Polish Academy of Sciences off the Napier Rock, Admiralty Bay, King George Island (South
Shetland Islands, West Antarctica), at the depth of 65-140 m. The characters of both species are
described with a special reference to the foreign material incorporated into coenecium. The
specimens collected will be used for further studies on the fine structure of coenoecia and zooids.
