Allen, RRS Discovery , Cruise 21, Sta. 6711 , 19 Mar 1968, EBS, 27.248°N, 15.605°W, 2988 m, holotype (LACM-AHF Poly 13266); 4 paratypes plus middle and post. fragments (LACM-AHF Poly 13267); Sta. 6709 , 18 Mar 1968, EBS, 27.537°N, 15.427°W, 2351 m, 3 paratypes (LACM-AHF Poly 13264); Sta. 6710 , 19 Mar 1968, EBS, 27.395N, 15.66°W, 2670 m, 1 paratype plus posterior fragments (LACM-AHF Poly 13265). Description . An elongate, threadlike species; all specimens incomplete, material includes anterior fragments with 12–13 setigers, abdominal fragments, and posterior fragments with bulbous posterior ends containing at least three setigers. Holotype (LACM-AHF Poly 13266) an anterior fragment with 13 setigers, 16.6 mm long, 0.36 mm wide across thorax and 0.38 mm wide across abdominal segments. Paratype (LACM-AHF Poly 13267) with 12 setigers, 12.4 mm long, 0.41 mm wide across thorax and 0.21 mm wide across abdominal segments. Dorsal surface of thoracic region with parapodia weakly elevated producing flattened channel along first seven setigers (Fig. 7A); following abdominal segments with relatively smooth surface interrupted by numerous transverse muscle bands. Ventral surface with mid-ventral ridge extending from peristomium to about setiger 6 (Fig. 7B), thereafter ventral surface relatively smooth, similar to that of dorsum. Color in alcohol light tan. Pre-setiger region about as long as first three thoracic setigers (Fig. 7A–B). Prostomium rhomboid-shape in dorsal view, widest medially, anteriorly tapering to broadly rounded apex, narrowing posteriorly, continuing as dorsal crest or ridge over peristomium to middle of setiger 3 (Fig. 7A); eyespots absent; nuchal organs distinct slits on posterior lateral margins anterior to first peristomial ring; dorsal surface with numerous small lumps ...
