Additional material examined. 8 specimens, AM W824, Australia, Macquarie Island, 54°30ʹ S, 158°57ʹ E. Description. Syntypes mainly well preserved with body wall intact, yellowish in colour, 2 complete and 1 incomplete individuals forming type series. Complete individuals 10 mm long (without tentacles), 1 mm wide for 50 segments and 15 mm long (without tentacles) and 1.2 mm wide for 65 segments. Posteriorly incomplete specimen (illustrated here and separated in a microvial from other syntypes) 10 mm long (without tentacles which are missing) and 1 mm wide for 37 segments. Dorsum anteriorly tessellated. Venter anteriorly with mid-ventral groove and discrete ventro-lateral pads; pads more-or-less smooth, extending from segment 3 to 12. Mid-ventral groove from segment 2 (Fig. 29a). Buccal tentacles numerous of two types, (1) cylindrical, thickened distally and distinctly grooved and (2) cylindrical, uniformly thin and weakly grooved, both arising at junction between prostomium and upper lip. Prostomial ridge distinctly curved, extending laterally along anterodorsal base of upper lip. Upper lip trefoiled with lateral blindly-ending enclosed diverticula, margin of medial lobe convoluted (slightly); oral surface glandular, ciliated, with grooves leading to mouth. Inner lower lip oblong, raised, ridged; outer region flat, shield-like, subtriangular and pointing toward mouth, ridged and grooved, extending posteriorly to segment 3. Achaetous segments visible dorsally but obscured by expanded outer lower lip ventrally. Notochaetigerous segments 30–34, extending to segments 32–36.
