Two species ofCoenitesEICHWALD,C. repens(WAHLENBERG) andC. hennigin.sp. are described. The structure of the skeleton has been studied using the light microscope microscope and scanning electron micrographs. The structure of the skeleton shows that a classifiation ofCoenitesamong the tabulate corals can no longer be maintained. Instead the genus belongs to the phylum Bryozoa.Coenitesis here referred to the order Cystoporata ASTROVA. The structure of the lunarium in Cystoporata andLichenoporidac(Cyclostomata) is briefly discussed.
