Vervoort, 1966: 162, figs dofleini: Millard, 1975: 421, fig. 130G. Description Two fascicled stems bearing phylactocarps, the longer 90 mm in and dimensions very similar to those of Vervoort (1966), to which thefollowing points may be added. The number of cauline nematothecae between two successive hydrocladiavaries from two in the distal region of the stem to six in the proximal part. Thehydrocladial internodes have a shorter distal region than those illustrated by 1 126 ANNALS OF THE SOUTH AFRICAN MUSEUM. Fig. 9. Cladocarpus sinuosus Vervoort. A. Hydrotheca with an abcauline intrathecal septum, and B, one without. C. Hydrotheca of var. edentatus dofleini (Stechow). D. Phylactocarp, and E, one of its nematothecae. F. in mm/10. THE SOUTH AFRICAN MUSEUMS MEIRING NAUDE CRUISES 127 Stechow (1925) and are more like those of Vervoort, but the spine on thehydrotheca is long, like that of Stechow. The distal end of the internode isoccasionally cut off as a short athecate internode. The phylactocarps are similarto those described by Stechow, but have no gonothecae. Measurements (mm) Hydrocladium, internode length 0,87-0,98 Hydrotheca, distance from adcauline edge to spine . 0,42-0,55 diameter at margin 0,20-0,27 Remarks This rare species is known from the African coast from the equator to theAgulhas Bank, and occurs only in depths over 425 m.
