The cirripedia (Crustacea) collected by the "Fisheries Steamer Meteor" in the eastern Atlantic

The "F.S. Meteor" made numerous dredges off the European and North African coasts, from the continental shelf to the abyssal plain. Thirty species were collected: Oxynaspis patens Aurivillius, Poecilasma aurantia Darwin, Lepas anatifera Linnaeus, Conchoderma auritum (Linnaeus), Heteralepas microstoma (Gruvel), H. cornuta (Darwin), Gruvelialepas pilsbryi (Gruvel), Aurivillialepas falcata (Aurivilllius), Pollicipes pollicipes (Gmelin), Scalpellum scalpellum (Linnaeus), Neoscalpellum debile (Aurivillius), Arcoscalpellum michelottianum (Seguenza), A. tritonis (Hoek), Planoscalpellum limpidus (Zevina), Amigdoscalpellum rigidum (Aurivillius), Trianguloscalpellum regium (Wyville-Thomson), T. ovale (Hoek), Verruca stroemia (Muller), M. recta Aurivillius, M. cornuta Aurivillius, Pachylasma giganteum (Philippi), Solidobalanus (Hesperibalanus) fallax (Broch), Megatrema anglicum (Sowerby), Balanus spongicola Brown, B. trigonus Darwin and, Megabalanus tulipiformis (Ellis); including four new species, Dichelaspis thieli n.sp., Litoscalpellum meteoria n.sp., Verum parazelandiae n.sp. and, Metaverruca sensibilis n.sp. The large-size species of Trianguloscalpellum (T. regium (Wyville-Thomson), T. darwinii (Hoek), T. giga (Hoek) and, T. ovale (Hoek)) are redescribed and their generic status is discussed. A key for the "large" scalpellids from the Atlantic and certain related Pacific species is presented. Three groups of species were observed along a depth gradient: a shallow-water species group occurring from the surface to 250m, a bathyal species group from 100m to 3000m, and a abyssal species group deeper than 2000m.
