Type locality. Arctic Ocean. Material examined. None. Description. Based on type description and figures. Type series consists of 29 specimens, up to 35 mm long for 65 chaetigers, body thicker than other members of the genus, wide, relatively short. Body colouration whitish when preserved. Venter anteriorly with mid-ventral groove and discrete ventro-lateral pads; pads more-or-less smooth, extending from segment 3 to 16 (at least). Mid-ventral groove from segment 2. Upper lip trefoiled, small wing-like lobes laterally (four folds are actually mentioned in type description; the extra fold is here interpreted as a convoluted medial lobe), margin of medial lobe convoluted. Outer lower lip subconical lobe protruding above venter (inferred from Fig. 27a). Notochaetigerous segments 19–21, extending to segments 21–23 (range of notochaetigerous segments for all specimens 18–25). Notopodia papilliform (inferred from Fig. 27a). Notochaetae within a chaetiger one type, gradually elongating from dorsal to ventral, smooth, narrowly winged (although wings not visible in fig. 2 of type description), uniformly tapered (Fig. 27b), posteriorly same form as those anteriorly. Neurochaetae beginning on segment 13–15, 20 uncini per row (approximation based on fig. 1 of type description). Neuropodial tori ridge-like, differ along body: relatively long on anterior chaetigers, longest in mid-body, becoming short on posterior chaetigers. Uncini with short neck and straight to convex base (Type 1), teeth above main fang arranged in double transverse series, subrostral process tooth-like (Fig. 27c). Comments . The original description is brief but sufficiently detailed to code and determine that the species can be distinguished from other Polycirrus species, in particular for its papilliform notopodia and one type of notochaetae (smooth, narrow wings).
