SUMMARY.Trichopus lachmanni n. sp. possesses, in common with other members of the family Dysteriidae, a fixation organelle composed of vesicles and a secretory ampoule. But no “foot‐like” appendix exists in this species, and the ampoule opens at the bottom of an antapical pit which bears a short fringe of membranelles derived from the somatic ciliature. The vibratile fringe participates in the spinning of the glutinous secretion which temporarily fastens the organism to the substrate. This specialized ciliature is characteristic of the genus Trichopus which was created by Claparède & Lachmann for a species, T. dysteria , which, though insufficiently described, is certainly different from T. lachmanni.
