| Summary: | Polycirrus eous Annenkova, 1924 Polycirrus eous Annenkova, 1924:126. Type locality. Kulku Bay, Okhotsk Sea, Russia. 59˚16′N 146˚20′E. Material examined. None. Description. Based on original description, body transparent when preserved, 15 mm long (no width indicated) with 55–56 segments. Venter anteriorly with mid-ventral groove and discrete ventro-lateral pads, ventro-lateral pads of first and second segments fused with each other. Mid-ventral groove from segment 3. Outer lower lip subconical, lobe protruding above venter (as stated in original description, 'large process which projects with an angle like point between parapodia of third segment'). Notochaetigerous segments 21, extending to segment 23. Notopodia more-or-less rectangular, long initially but becoming small and rounded on segments 10 and 11. Notochaetae within a chaetiger of one type, pinnate (the translator used term spicate), posteriorly presumably same form as those anteriorly. Neurochaetae beginning on segment 13. Uncini with short neck and straight to convex base (Type 1), teeth above main fang arranged in double transverse series (MF:1:5) enlarged median tooth above main fang present. Comments. The original description lacks any illustrations, but there is sufficient character information to be able to code the important features and it keys out as a distinct species.
