Abstract: Antarctic benthic ostracods V.-Ostracods from the south winter cruise ofthe F. S. "Polarstern" (Ps 9N-l) to Elephant Island and the Antartic Peninsular. - The winter cruise of F. S. "Polarstern" was the most successful so far for the collection of ostracods, with 56 species found. Of these 7 are new to science, 3 have to remain in open
omenclature, the remaining 46 already being known. A new genus
Pseudeucythere can also be erected on the base of the material collected. An important find is also that 47 of the species carried eggs, embryos or were represented by larvae, indicating that most of the Antarctic ostracods also reproduce during winter.
The remaining 9 species were only found in small numbers, from which it was not possible to decide if they were also undergoing reproduction. Data will also be presented indicating patchiness of distribution, since it was possible to collect material in series of up to 6 grab sampies of a single station.
