Both traditional and cladistic taxonomists rely for their analyses upon the same basic data obtained from comprehensive anatomical descriptions of individual species. For nemerteans these data arc at present inadequate, and attempts to devise classificatory schemes based on cladistic studies are not realistically feasible when so many of the individual taxonomic units to be analysed contain unidentifiable polyphyletic groups.
