Brada inhabilis.— Malmgren 1867: 194 (partim).— Haase 1915: 206 –209, Textfig. 9 (partim, non Rathke, 1843). Type material. Northwestern European Arctic Ocean. Lectotype (ZMUB 18605), Norwegian North Atlantic Expedition, no further data, previously identified as B. granulata by A. Hansen. Two paralectotypes (ZMUB 2195), Norwegian North Atlantic Expedition, Sta. 374 (78°16' N, 11°17' E), Advent Bay, Spitzbergen, Norway, no further data (42–47 mm long, 7–9 mm wide, cephalic cage chaetae missing, 24–25 chaetigers). One paralectotype (ZMUB 2198) dark, mature female, previously dissected, damaged, with many pale epizoic anthozoids, Danesgat, Spitzbergen Expedition, sandb. Med sten + ler., 37 m, Sep. 1861, Malmgren, coll. (35 mm long, 8.5 mm wide, cephalic cage chaetae broken, 25 chaetigers; oocytes about 125 µm). Description. Lectotype (largest specimen, ZMUB 18605) pale, body truncate in both ends, medially swollen (Fig. 5A); 49 mm long, 8 mm wide, cephalic cage 1.0 mm long (a single neurochaetae), 24 chaetigers. Papillae forming 2–3 transverse ridges per segment, anteriormost and posteriormost segments with all ridges fused; all papillae conical, long. Dorsally, papillae with adhering sediment grains forming ridges as long as whole chaetiger, leaving narrow intersegmental furrows; ventrally papillae adhering sediment without forming ridges. Anterior end morphology observed in damaged paralectotype (ZMUB 2198). Cephalic hood not exposed. Prostomium low pale cone; eyes not seen. Caruncle triangular, narrow, continued posteriorly almost reaching posterior branchial plate margin. Palps thick, smooth, pale; palp keels rounded, low. Lateral lips dark, well developed (Fig. 5B). Dorsal lip triangular, reduced. Ventral lip reduced. Branchiae all cirriform, thick, blunt, sessile on ...
