- free living
Old talk 
The phylum Platyhelminthes has recently undergone major reorganization. The classical split into Cestoda, Monogenea, Trematoda and Turbellaria is no longer valid, both based on morphological and molecular evidence (see the article by Seth Tyler at http://devbio.umesci.maine.edu/styler/globalworming/platyhelm.htm).
Seth Tyler and his colleagues also maintain the most up-to-date taxonomic database for the free-living members of this phylum (i.e. the group that was formely called Turbellaria). This database can be found at http://turbellaria.umaine.edu
Vernacular Names? 
The vernacular names aren't showing up, but I don't know how to fix the coding that's in there.

What do you propose for the subdivisions?
Monogenea needs to be splitted in Monopisthocotylea and Opisthocotylea (unless you favor classification according to larval phasis)
