Some rugose corals from the Upper Permian of East Greenland

Rugose corals are described from the Upper Permian Foldvik Creek Formation of Hold with Hope and Wegener Halvø, East Greenland. Specimens described from the same area by H. W. Fliigel in 1973 have been re-examined and revised. Among three species identified, Allotropiochisma birkenmajeri n.sp. belongs to a new genus, into which all Fliige!'s species of Amplexizaphrentis are inc1uded. All new species of Calophyllum introduced by Fliigel are synonymised with Calophyllum profundum (Geinitz, 1842). The new subgenus Groenlandophyllum introduced by Fliigel is not accepted. The life habits of corals and their adaptations to a muddy bottom are reconstructed and discussed.
