On some more protozoan parasites from Trichoptera

Abstract
In a recent paper (Journal of Parasitology, 1910, III. pp. 245—54) I described a new trichomonad (Trichomastixc trichopterorum) and a spirochaete from the hind-gut of certain trichopterous larvae. I also mentioned the occurrence along with these parasites of another peculiar flagellate, which, at the time, I was disposed to consider as closely related to Macrostoma caulleryi, Alexeieff.
