The study of the protozoan plankton is based on the materials of surface water collected from the seas between Antarctica and Africa during the third and fifth voyages of the SOYA (1957-1958; 1959-1960). From these plankton samples of the antarctic and the subantarctic seas have been secured 31 forms of the flagellates, a single of the pelagic foraminifera and 44 of the ciliates. Of the total 76,18 are new species or new varieties, including one new genus. From the study it is clear that the species of the following three orders occur frequently in surface water of the southern antarctic area of the Indian Ocean : the Dinoflagellida including the unarmored genera, Amphidinium, Gymnodinium and Gyrodinium and the armored genus, Peridinium, the Oligotrichida having the marine common genus, Strobilidium, and the Tintinnida comprising the characteristic genera peculiar to antarctic waters, Laackmanniella, Protocymatocylis and Cymatocylis. Furthermore, the highest frequency of occurrences of the protozoan plankton has been observed in the materials obtained from surface water of 0-5℃ in the antarctic seas.
