Bradabyssa ochotensis (Annenkova-Chlopina, 1922) n. comb. Figure 27 Brada ochotensis Annenkova-Chlopina 1922: 39.—Uschakov 1955: 310(1965: 287), Fig. 115J.—Levenstein 1966: 45.—Jirkov & Filippova 2001: 354. Type material. Holotype (ZIRAS 26654), Sakhalin Bay, Okhost Sea, R.V. Liuetenant Dydymov, Sta. 400 (53°32' N, 141°15' E), 24 m, sand, 14(27) Aug. 1913, V.K. Soldatov, coll. Additional material. One specimen (ZIRAS 26655), Bering Sea, R.V. Plastun, Sta. 3 (63°11' N, 172°35' E), 66 m, 12 Sep. 1931, coll. (85 mm long, 8 mm wide, cephalic cage 4 mm long, 31 chaetigers, gonopodial lobes in chaetiger 5, 5–6 series of dorsal papillae; dissected for introvert details). Description. Holotype (ZIRAS 26654) complete (Fig. 27A), few parapodia previously removed, anteroventrally dissected. Body stiff, pale, slightly tapered posteriorly; 62 mm long, 12 mm wide, cephalic cage 5 mm long, 32 chaetigers. Tunic papillated, most larger papillae distally eroded, smaller ones covered by sediment. Papillae and integument finely covered by fine sand grains, not forming large sand tubercles. Papillae in two slightly different sizes and shapes; smaller ones digitate, larger ones globose, mucronate, about as large as neuropodial lobes, all arranged in 5–6 alternating series in median chaetigers (Fig. 27B). Anterior end not exposed (observations made through original dissection, completed with another dissected specimen (ZIRAS 26655). Prostomium dark brown, rounded, low, eyes not seen. Palps short, heavily contracted, thick, with longitudinal furrow, and long tip (due to compression), shorter than branchiae; palp keels dark brown, rounded, elevated. Caruncle well developed, reaching posterior margin of branchial plate; median keel basally wide, elevated, lateral ridges dark, lower than keel. Lips grayish, thick; dorsal lip triangular, lateral lips thicker, ventral lip darker, slightly projecting. Branchiae cirriform, sessile on branchial plate, separated into two lateral groups, filaments arranged in several rows, over 100 filaments ...
