Description
Summary:Clytia gigantea (Hincks, 1866) (Fig. 5A–B) Campanularia gigantea Hincks, 1866: 297; 1868: 174, pl. 35 fig. 1; Jäderholm, 1909: 69, pl. 7, figs 1–3; Christiansen, 1972: 293. Clytia gigantea — Hirohito, 1995: 61 –63, fig. 18a, b; Vervoort & Watson, 2003: 418, 419, fig. 102J; Calder, 2012: 46 –47, figs 46–47. Material examined. 51103#5, one stem 13 mm high and two extra hydrothecae, no gonothecae. Description. The 13-mm-high stem is provided with three hydrothecae (two of them broken). The isolated hydrothecae are provided with a very long pedicel. Hydrotheca elongate, roughly cylindrical in distal half, tapering in basal half (Fig. 5A). Rim of hydrothecal aperture with eight to 13 cusps, with smoothly curved distal part, curved inwards, and separated by deep, rounded embayments (Fig. 5B). Measurements (in µm). Hydrotheca: height 1100–2000, diameter at aperture 400–840, diameter at diaphragm 100–140, height of basal chamber 40–100. Remarks. The two isolated hydrothecae are distinctly smaller (1100–1240 high ... : Published as part of Peña Cantero, Álvaro L. & Horton, Tammy, 2017, Benthic hydroids (Cnidaria, Hydrozoa) from bathyal and abyssal depths of the Northeast Atlantic held in the modern Discovery Collections, pp. 1-30 in Zootaxa 4347 (1) on page 13, DOI: 10.11646/zootaxa.4347.1.1, http://zenodo.org/record/1044772 ...
