Three new species of polychaete jaw apparatuses are described. They have been chemically prepared from Zechstein deposits, from bore holes in Northern Poland. The following systematic units have beien established: the monotypic
family Kielanoprionidae n. fam. with Kielanoprion pomeranensis n. gen., n. sp., as well as Oxyprion compressus n.gen., n.sp. (Mochtyellidae Kielan-Jaworowska) and Atraktoprion eudoxus n. sp. (Atraktoprionidae Kielan-Jaw.). These apparatuses are compared with other apparatuses and fossil scolecodonts as well as with recent forms.
