Tokoprymno anatis sp. nov. Figures 13–16 Material examined. Holotype: ZMH C 11749, ANT XIX/ 3, stn PS 61 /046-08, 60 ° 38.79 'S, 53 ° 57.42 'W, north east of Elephant Island, Antarctica, 2895.6–2896.4 m depth, 2 February 2002, one colony, fragmented. Fragments of the holotype have also been deposited in USNM 1145316. Description of the holotype. Colony bottlebrush (Figure 13 A), fragmented in three main parts of 5, 7 and 9.5 cm in length, 22 cm in total length and 10.5 cm in width. Simple or scarcely ramified stiff branchlets (Figure 13 B) up to 6.5 cm in length, proximally almost perpendicular to stem, then curving upward. Axis bronze, stiff, broken proximally. Basal axis diameter 3 mm. Polyps perpendicular to branchlets (Figure 13 B, 14 A), absent on main stem, singly or biserial placed (Figure 14 A), 6–11 polyps per cm. Polyps (Figure 14) relatively elongate, slightly clavate, up to 2.4 mm in height and 0.61–0.97 mm in diameter, with a conical operculum. Polyp body with 8 longitudinal rows of scales somewhat disorganized, adaxial body scales smaller (Figure 14 B), 4–5 transverse rows of scales in the abaxial aspect overlapping one another (Figure 14 C). Accessory opercular scales (Figure 15 A), blade-shaped, variable in number from absent to two, small, about 0.49 mm in height and 0.12 mm in width. Proximal half of inner surface tuberculate, smooth distally, without keel. Margin finely serrated. Outer surface almost smooth, few granules. Opercular scales (Figure 15 B) eight in number, 0.58–0.84 mm in height and 0.15–0.28 mm in width, duck-beak shaped with rounded tips and square or bilobed base. Proximal inner surface tuberculate covering up to half of their length; distal part convex, with granules forming ridges or with a small keel. Outer surface almost smooth with a few granules proximally. Free margin serrated. Marginal scales (Figure 15 C) eight in number, more-or-less triangular, 0.52–0.91 mm in height and 0.27– 0.44 mm in width. Inner surface tuberculate covering at least 75 % of the scale, with ...
