Abstract : The annelid worms which are epizoic on horartic freshwater crustaceans were considered by their discoverers to be leeches (Odier, 1823). At a later period they were assigned to the oligochaetes (Vejdovsky, 1884; Michaelsen, 1909; Pierantoni, 1912). The question of their affinities has recently been reopened (Franzen, 1963). The author reviews the structure, distribution, and habits of these animals, currently included in the oligochaete family Branchiobdellidae and advances additional reasons for his belief that this family should be elevated to ordinal rank.
