Notes
Twelve strains of the common marine genus Platyamoeba (Protozoa: Rhizopodea, Amoebida), isolated from sandy beaches and estuaries of East Anglia, were found to belong to four new species: P. flabellata, P. bursella, P. calycinucleolus, and P. plurinucleolus. Specific identification is possible on the criteria of locomotive form and behaviour, nuclear structure, and mitotic pattern, with further information provided by size and floating form. This investigation further establishes the criteria for both the genus and species within the genus. The distinctions between Platyamoeba and other genus of Thecamoebidae are discussed. Experimental results demonstrate that all these species are fairly euryhaline and that there is a good degree of agreement in their physiological characteristic within a species. Strains from estuaries were not more tolerant than were those from open beaches, and these results do not indicate that the same species might invade fresh water. Platyamoeba and Paramoeba appear to be among the most common genera in British coastal waters as in North American waters.
