Some marine ciliates, chiefly belonging to the genus Cothurnia are recorded from Plymouth and figured. Three new species are described.
Little has been published on the Ciliata from Plymouth waters. The publications of de Morgan (1925, 1926) alone provide a detailed description of some species. In the last edition of the Plymouth Marine Fauna (Marine Biological Assoc, 1957) many species have been recorded not described by de Morgan but which were occasionally mentioned in the works of other authors, and included those investigated by the present writer during her visits to the Plymouth Laboratory in the years 1953 to 1963. Recently, a list of Protozoa observed at Plymouth has been published by Lackey & Lackey (1963).
