Abstract / Notes
On the shells of Hydrobia stagnalis lives a whole biocoenosis of unicellular organisms, incl. Cothurnia innata, Stichotricha muelleri, Stentor auricula, Vaginicola hydrobiae, and Zoothamnium hydrobiae; larvae of the polychaetes Streblospio dekhuyzeni, Polydora ciliata, Capitella capitata, Nereis diversicolor and Nerine cirratulus. Two very remarkable turbellarian worms are described Alaurina composita (the Zuider Zee must be regarded as the typical place of maximum development of this sp., which was also found in the northern seas near Jutland by Brinkmann) ; and Stylochus flevensis, with 4 developmental stages discussed. This is the most northern habitat of the genus Stylochus known. A list is given of all tropical or subtropical animals and plants known from the Zuider Zee.
