Observations during four dives in the submersible ‘Alvin’ in June 1976 revealed that ctenophores were the most abundant large plankters between 400–700 m. From specimens collected with a slurp-gun device, Bathocyroe fosteri gen.nov., sp.nov., a species characterized by strong lobes, large auricles and red pigmentation of the gut, is described. Few ctenophores have been collected previously from deep water, but observations from submersibles indicate that several species occur throughout the mesopelagic zone.
