Diagnosis (adapted from Williams 1990 , modifications in bold) Rachis long and slender. Axis quadrangular to round in cross section. Autozooids restricted to the distal terminus, usually forming an umbellulate cluster. Siphonozooids are present on the rachis at the base of the autozooids or on bare parts of the rachis. Sclerites either present in peduncle, rachis , and terminal cluster, or totally absent. When present, sclerites are rods, spindles or needles, three-flanged round in cross-section. Included genera Umbellula Cuvier, 1798 . Distribution Cosmopolitan, from 250 m to over 6200 m deep ( Williams 2011 ). Table 1 (continued on the next page).
