Its rapidmotion and very translucent appearance render it extremelydifficult to examine it properly. The membranous appendage,as mentioned above, differs essentially from that of the Holo-trichous Cyclidium or Pleuronema. Genus polygonum, Elnenb.

Opisthotricka parallela, Engelm, var. minor, var. nov. PlateIV., fig. 27. Agrees with the European species in everything but its size,which is only 3 L inch =70 ^u.

The specimens examined appeared nearly identical with thisspecies, but the tentacles could not be resolved into clearlyseparate fascicles, seeming rather to be irregularly scatteredover the whole body. The animalcules were all on stems ofvarious Alga: none were observed parasitic on Epistylis. Genus flos, sp. nov. Plate IV., fig. 28.
