FIGURE 2. Interpretative images illustrating morphological terms and measured characters. A, part of creeping tube (ct) of an unidentified Rhabdopleura (NIWA 158518) from Kermadec Ridge, with flat lateral margin (flm), faint oblique fusellar sutures and two ringed erect tubes (et) produced directly from the frontal surface of a creeping tube. B, distal end of an erect tube of Rhabdopleura francesca n. sp. (NIWA 158157), showing a vertical series of ring-like fuselli (f), the rim of each comprising a curled fusellar collar (fc). Tube diameter (td) is measured between fusellar collars; fusellus height (fh) is the distance between the bases of a pair of fusellar collars. C, transmitted-light image of part of a principal ('creeping') tube of R. emancipata n. sp. (NIWA 161211) showing a young zooid with contracted arm tentacles (at), stomach (st), rectum (r) and cephalic shield (cs), part of which is concealed by the reddish-brown stolon (black stolon or pectocaulus). D, aperture of an erect tube of R. francesca n. sp.; note the smooth-surfaced interior devoid of vertical fusellar fibrils. E, part of a creeping tube of an unidentified Rhabdopleura (NIWA 90267) from Cavalli Seamount with frontal fusellar sutures (fs, two arrowed). The white lines show the zigzag (zz) portion of the sutures (note the proximalwards shift to the left), with zigzags rendered as straight lines between points of intersection, regardless of suture curvature, to obtain measured angles (one example shown). F, close-up of part of R. francesca n. sp. (NIWA 158157) showing chains of dark 'dormant buds' (db) lying upon short stretches of the black stolon (bs); walls of enveloping creeping tubes almost invisible in image.
