Two long and slender cephalic tentacles. Epipodial tentacles seven pairs, all slender, first two short, remainder long (Fig. D, 6).. Fig. D. Epipodial processes in Trochoids. CT = cephalic tentacles, £T = epipodial processes and 0/> = opercula in: (1) Calliostoma modestulum Strebel; (2) Photinastoma taeniata (Wood); (3) Solariella kempi n.sp.; (4) Photinula coerulescens (King & Broderip); (5) Falsimargarita iris (Smith); (6) Venustatrochus georgianus n.g., n.sp. 5. Falsimargarita iris (Smith). Two short and very stout cephalic tentacles. Epipodial tentacles seven pairs, very short and stout and of equal size (Fig. D, 5). Eales (1923, p. 8) described F. gemma (Smith) as being similar but with the epipodial tentacles scarcely distinguishable from the lobes of the epipodial fringe. 6. Margarella expansa (Sowerby); also steineni (Strebel), bouveti n.sp., M. (Promargarita) tropi- dophoroides Strebel and achilles (Strebel). All with short and stout cephalic tentacles and four pairs of moderately long epipodal tentacles, which increase in size gradually from the front. 7. Margarella antarctica (Lamy). Similar to the typical Margarella series listed above except for five instead of four pairs of epipodial tentacles.
