Comactinia

Abstract: Three new species of unstalked crinoids (Echinodermata, Crinoidea) belonging to the comasterid genera Comactinia A H Clark, 1909, Capillaster A H Clark, 1909 and Cenolia A H Clark, 1916 from depths of 73-310 m, are described Comactinia titan n sp, from the Philippines and New Caledonia, which bears thicker arms than any other comasterid, is the first representative of its genus recorded outside the tropical western Atlantic Capillaster squarrosus n sp, from Vanuatu, resembles C multiradiatus (Linnaeus, 1758) but has uniquely modified arms Cenolia amezianeae n sp, from southern New Caledonia and Vanuatu, resembles its congeners but bears combs on pinnules as far as P 19 (rather than just to P 4 as in other Cenolia), which requires an emendation of the generic diagnosis RESUME
