The position of flagellated protists in the system of lower eukaryotes.
The division of Eukaryota into 8 kingdoms united into 3 superkingdoms is briefly discussed with the rejection of the hypothesis of symbiogenesis and of primary nature of the dinokaryon. It is asserted that Pascher's main hypothesis remains valid. The heterotrophic flagellated and amoeboid forms must be included into different groups of flagellated beings. Some of them: Saprolegniomycetes, Hyphochytridiomycetes, Slopalinata, Cryptaxohelid Heliozoa have been already put into chromophytan branch. Others differ from autotrophic groups more sharply and their taxonomic position may be stated now only tentatively and will be specified as a result of future studies.
