Canadian subarctic: Western Hudson Strait, CSS Hudson cruise 90-023, Sta. 100, collected between 23 September and 16 October 1991, van Veen grab, 63°04.07ʹN, 74°34.00ʹW, 393 m, Western Hudson Strait, holotype (LACM-AHF Poly 6535), 19 paratypes (LACM-AHF Poly 6536). Southern Baffin Bay , R/V Hero Sta. 26 A, 1745 m, 67°49ʹN, 60°46ʹW, coll. J.A. Blake, 16 Aug 1968, 8 specimens (USNM 51222). Description. A moderate-sized species, holotype complete, 11.5 mm long, 0.8 mm wide across thoracic region, with 80 setigerous segments; all paratypes incomplete but of similar size as holotype. Body widest anteriorly, with short, crowded segments (Figs. 5 A–B, 6A), narrowing posteriorly with segments becoming nearly as long as wide (Fig. 6 D); one of two ovigerous paratypes with abdominal segments nearly moniliform, with body widest anteriorly, narrow crowded segments at least 8–10 times wider than long; segments then becoming about as wide as long in middle body with posterior segments narrowing to about 3–4 times wider than long. Without any distinct dorsal groove along body; with weak ridge along ventral midline (Figs. 5 B, 6B). Color in alcohol light brown with anterior segments sometimes with black pigment pattern (Fig. 6 A), faded in other specimens; Baffin Bay specimens more darkly pigmented. Prostomium triangular, narrowing to pointed anterior end (Figs. 5 A–B, 6A–C), without eyes; nuchal grooves on posterior margin of prostomium, sometimes pigmented in Baffin Bay specimens. Peristomium complex, with three incomplete anterior annulations producing two relatively large achaetous rings and a narrower posterior ring bearing dorsal tentacles (Fig. 5 A–B); peristomium extending posteriorly to setiger 1, overlying a narrow achaetous segment bearing first pair of branchiae (Fig. 5 A); second pair of branchiae on posterior margin of setiger 1 dorsal and medial to notosetae, subsequent setigers ...
