Paraonella nordica. — Strelzov 1973: 147 –148, fig. 67; Kedra et al . 2011: 430; 2013: 813–814. Material examined. ZISP 5/38014; Barents Sea; 72.0366°N-51.1133°E; 87 m; muddy sand and pebbles with gravel 06.09.1959; one paratype. ZISP 2/38011; Barents Sea; 72.50°N-46.60°E; 60 m; shells and gravel 09.09.1959; two paratypes. Description. Longest specimen complete, 9.3 mm long for 56 chaetigers, 0.15 wide at tenth chaetiger level. Prebranchial and branchial regions very slightly flattened, postbranchial region cylindrical. Preserved specimens whitish, without any colour marking. Prostomium distally rounded, nearly twice longer than wide (Fig. 10A); antenna, apical sensory organ and eyes absent. Mouth anteriorly oriented, posterior lip extending through first chaetiger only. Nuchal organs straight and oblique, joining to posterior end of prostomium (Fig. 10A); secondary ciliary organs absent. Branchiae digitiform, with rounded tips (Fig. 10A, B), occurring from chaetiger 5 to chaetiger 10; all similar in length, nearly reaching mid-dorsal line, except the last pair, which is half as long; ciliation not observed. Notopodial postchaetal lobes very short and papilliform in prebranchial region, minute on chaetigers 1 and 2, slightly larger on chaetigers 3 and 4 (Fig. 10A); progressively increasing in length through branchial region, becoming digitiform on chaetigers 8 onwards (Fig. 10B), about one quarter the length of corresponding branchia, except for chaetiger 10, where the branchiae are shorter; not observed in post-branchial region. Neuropodial postchaetal lobe as low ridge, of even height all along body (Fig. 10 B, C); interramal process not observed. Pygidium squared, pygidial cirri not observed. Chaetae arranged in two rows in both noto- and neuropodia, those of posterior row clearly longer; notochaetae thin and slightly curved, numbering 10 on chaetiger 3 and 14 on chaetiger 9, gradually decreasing to seven on ...
