 note = {P(論文), A small material of appendicularians collected in the Antarctic Seas was examined morphologically and taxonomically. Full descriptions are given for Antarctic or Subantarctic species so far described rather insufficiently, besides morphological and taxonomical notes on some others. Especially a taxonomical discussion is made on the oikopleurid-group involving O. gaussica, O. valdiviae, O. drygalski and O. weddelli, leading to a possible conclusion that these might belong to the single species, O. gaussica.},
