A second species of the unique cheilostome bryozoan genus Fatkullina, with reversed-polarity zooidal budding, has been discovered. Fatkullina imitata n. sp. is described from the western Kamchatka shelf and upper slope of the Sea of Ok- hotsk. It differs from the type species, F. paradoxa, by the combination of orificial characters, the convex distal third of the frontal shield, and predominantly crimson coloration of dry colonies. A new family, Fatkullinidae, is erected to accom- modate Fatkullina (as the type genus) and also Stomacrustula, Pachyegis and Lepralioides. The origin of reversed polarity zooidal budding is considered to arise as a consequence of the unique T-shaped geometry of the ancestrula and transverse daughter zooid followed by spiral budding of periancestrular and succeeding generations of zooids within the zone of as- togenetic change.
