The vertical distribution patterns of Paraphyllina ransoni Russell, 1956, Periphylla periphylla (Péron & Lesueur, 1809), Atolla parva Russell, 1958, A. vanhoeffeni Russell, 1957, and A. wyvillei Haeckel, 1880 are described. A comparison with other bathypelagic taxa shows that there are various upper limits to be drawn for the bathypelagic area. Four typically different vertical distribution patterns are described.
