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.
