Abstract / Notes

The collection taken at 350 m. comprised members of the Acoela, Rhabdocoela, and Alloecoela. Of the Acoela
only one species, Rimicola glacialis Bohmig, was present. Rhabdocoela, Polycystididae Porrocystis,
with P. drygalskii. The characters of this new species necessitate a revision of Meixner's scheme
for the Polycystididae with the recognition of 6 genera: Polycystis, Macrorhynchus, Acrorhynchus,
Phonorhynchus, Porrocystis, and Progyrator. Alloeocoela, Gnosonesimidae is founded for Gnosonesima, with G.
antarctica, the only known turbellarian in which the oviduct leads directly into the intestine, thus
supporting Steinbock's idea that the eggs were originally discharged through the intestine and mouth. The
former status of Lecithoepitheliata as an aberrant group is greatly altered by the
discovery of this species which is a primitive type leading into the Alloeocoela and Rhabdocoela.
Rhabdocoela, Cylindrostomidae: Cylindrostoma vanhoffeni, C. gaussi, Monoophorum ruseni, Plagiostomidae: P.
opisthogonimum, similar to P. lemani which is thus not so isolated as supposed.
