In this biocoenosis the most numerous among the Polychaeta are Lumbriconereis impatiens, Myriochele oculata, Praxilella praetermissa, Rhodine gracilior; among the Mollusca Leda (pernula?), Macoma moesta, M. torelli, Musculus corrugatus, Yoldia traciaeformis, and Nucula tenuis; there are numerous Crustacea (families Ampeliscidae). Among the Deca- poda there are Chionoecetes opilio, Hyas coarctatus, Pagurus pubescens; the Polychaeta Nephthyidae, Aphroditidae; and the starfish Crossaster papposus, Pteraster and Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Zenkevich, L.
