Besides the above, Dangeard, in various papers in his periodical Le Botaniste, has treated of most of the groups, and Raoul Francé has monographed the Polytomeae in the Jahrb. wiss. Bot. xxvi. 1894, p. 295, and Dill the genus Chlamydomonas, etc., its closest allies, in op. cit. xxviii. 1895, p. 323.
For a detailed abstract of our knowledge of Trypanosoma and its allies up to Feb. 1, 1906, see Woodcock, "The Haemoflagellates," in Quart. Journ. Micr. Sci. 1. 1906, p. 151.
