5. Apomatus globifer Théel, 1878, Arctic, Norway; probably see A. similis 6. Apomatus lilliei Benham, 1927, North Cape, New Zealand 7. Apomatus similis Marion & Bobretzky, 1875, Mediterranean Atlantic; probably includes A. globifer 2. Bathyditrupa Kupriyanova, 1993b (Fig. 9) Type-species: Bathyditrupa hovei Kupriyanova, 1993b Number <strong>of</strong> species: 1 Tube free, curved but not coiled, white, opaque, rectangular in cross-section; collar-like rings absent. Granular overlay absent. Operculum inverse conical, with brown chitinous endplate, flat or slightly concave. Opercular ampulla gradually merges (constriction absent) into thick, rather triangular peduncle with pinnules, but without wings. Peduncle inserted as the second dorsal radiole on one side. Pseudoperculum absent. Arrangement <strong>of</strong> radioles semi-circular, up to 6 per lobe. Branchial eyes not observed. Inter-radiolar membrane and stylodes absent. Mouth palps not observed. 5 thoracic chaetigerous segments. Collar non-lobed, short, with entire edge. Tonguelets absent. Thoracic membranes short, ending at second thoracic segment. Collar chaetae limbate (Fig. 9A). Apomatus chaetae absent (Fig. 9B). Thoracic uncini saw-to-rasp-shaped, with up to 4 (?6) teeth in a row above peg, with about 15 curved teeth in a row in pr<strong>of</strong>ile (Fig. 9D). Anterior peg bifurcate in high-power microscopy, but clearly gouged when studied by SEM (Fig. 9E). Thoracic triangular depression absent. Abdominal chaetae all capillary (Fig. 9C), posterior ones slightly longer; abdominal uncini raspshaped (Fig. 9F). Achaetous anterior abdominal zone short, just one or two segments. Posterior glandular pad absent. Remarks. This abyssal species had only been reported from the Kurile-Kamchatka trench (Kupriyanova 1993b). We studied 2 additional specimens from the North Pacific Ocean, collected by the R/V Vityaz, Sta. 3151, near the Emperor Seamounts, 44°28'3'' N 170°07'0''E, grab, 5237 m, ZMA V.Pol. 5326; Sta. 4370, NE <strong>of</strong>f Hawaii, 26°04'2'' N, 153°49'3'' W, grab, 6050 m, ZMA V.Pol. 5325. The characteristic feature <strong>of</strong> the genus is a free, unattached tube similar to that <strong>of</strong> Ditrupa, but rectangular in cross-section and without an outer hyaline layer (see The tube, p. 7). It is probably synonymous with Nogrobs fide Jäger (2004: 140), see remarks below (p. 69). Bathyditrupa hovei Kupriyanova, 1993b, Kurile-Kamchatka trench and North Pacific Ocean; abyssal. 3. Bathyvermilia Zibrowius, 1973a (Fig. 10) Type-species: Bathyvermilia challengeri Zibrowius, 1973a Number <strong>of</strong> species: 5. Tube white, opaque, circular in cross-section, longitudinal keel may be present. Collar-like rings present. Granular overlay absent. Operculum sub-globular, with simple flat to slightly conical chitinous endplate, which may be encrusted by calcareous deposit. Peduncle cylindrical, smooth or wrinkled, without distal wings; inserted as second dorsal radiole on one side, constriction present. Pseudoperculum absent. Arrangement <strong>of</strong> radioles in semi-circles, up to 35 per lobe. Inter-radiolar membrane absent. Branchial eyes not observed. Stylodes absent. Mouth palps may be present. 7 thoracic chaetigerous segments. Collar trilobed (may be non-lobed) with entire edge, tonguelets absent. Thoracic membranes variable, ending at 2 nd —7 th thoracic segment. Collar chaetae limbate. Apomatus chaetae present (Fig. 10A).
