Notes

Three species of marine amoebae were studied by light- and electron-microscopy. Two new marine species of Vannella from England and Scotland have surface structures identical with those previously described for three freshwater species from Germany and the U.S.A. Three strains from England, Scotland, and the U.S.A., identified as belonging to the species Vexillifera pagei Sawyer, 1975, have surface structures differing from those of two marine species of Vexillifera but probably a modification of the latter. On the basis of both light- and electron-microscopical characters, V. pagei is made the type-species of a new genus, Pseudoparamoeba. The usefulness of several taxonomic characters is discussed on the basis of the present investigation. Surface structure is of special value in distinguishing genera of Gymnamoebia.
