On two new genera of Bryozoa Cheilostomata from the Tortonian of Poland
Jerzy Małecki
Two new species of Bryozoa Cheilostomata, considered representatives of the two new genera, Xaveropora n.gen. and Christinella n.gen., are described from the clayey and sandy deposits of the Tortonian of Poland. Xaveropora ojcowensis n.sp, is marked by ovicells situated in front of the orifice; this type of an ovicell has been called by the author a prostomial ovicell. Christinella pulchra n .sp, is distinguished by itsendozooecial ovicells which, with time, grow
and completely cover the opesia.
