Description . Preserved specimen grey to pale cream in colour. Body small, conical in shape. Tube curved, composed of cemented shell-like fragments, or composed of sand grains. Rim of cephalic veil with 17 long cirri. Cirri are triangular appendages, which rapidly taper ( Fig. 9A ). Cephalic veil completely free from operculum, forming a dorsal semi-circle around the numerous buccal antennae. Raised opercular margin well developed, smooth. Operculum with 10 pairs of paleae, yellow-gold, subacute, curved dorsally, long without extended tips. First pair of tentacular cirri arise from anterior edge of segment 2. Ventral ridge connecting second pair of tentacular cirri on segment 3 incised to form glandular lobes. Segment 2 lacking posterodorsal lobe. Chaetiger 2 with anteroventral lobe large and broad; anterior margin of lobe with 13 contiguous rounded papillae. Two pairs of comb-like, stalked branchiae on segments 3 and 4, situated laterally and consisting of loose flat lamellae.Anterior pair situated more ventrally than posterior pair, both pairs similar in size, lying flattened against the body. Chaetigers 1 to 3 (segments 5 to 7) with notopodia and notochaetae only. Chaetigers 4 to 16 biramous with both notopodia, neuropodia, and notochaetae and neurochaetae. Chaetiger 17 with only notopodia and notochaetae. Notochaetae from chaetiger 5 include smooth winged capillaries, and capillaries with finely serrated margins ( Figs. 10A ). Notochaetae from chaetiger 14 with finely hirsute surfaces. Notochaetae of chaetigers 1–3 and 15–17 reduced in size compared to those of notopodia 4–14. Neuropodia wedge shaped, erect and glandular. Neurochaetae with major teeth arranged in two rows, 6–10 teeth per row ( Figs. 10B,C , 12A ). Posterior scaphe and abdomen distinctly separated. Posterior 5 segments fused to form a flattened plate or scaphe longer than broad, with crenulated margins ( Fig. 9B ). Anal flap present with dorsal papilla. Scaphal hooks present, 7 pairs, broad, blunt, brown ( Fig. 12B ). Glandular areas present on chaetigers 4 to 17, prominent, ventrally glandular on segments 1–6. Nephridial papillae present on segments 3 and 4, inserted ventrally at base of branchiae. Variation . The number of cirri on the cephalic veil margin varies from 19 to 29, and the number of papillae on the anteroventral lobe of chaetiger 2 ranges from 12 to 19. The size of the anterior pair of branchiae varies such that on some specimens they are larger than the posterior pair. The number of scaphal hooks varies from 6 to 8 pairs. The development of the glandular areas varies between specimens. Most of these variations appear to be size dependent, with larger animals having more cirri, papillae and pairs of scaphal hooks than smaller individuals. Remarks . Schmarda’s type of P. antipoda could not be located. Most of Schmarda’s material is housed in the Naturhistorisches Museum in Vienna. Dr Helmut Sattmann, the Curator of polychaetes at this Museum, confirmed that no material of P. antipoda was present in their collections. The species has been reported from Australia several times since it was described in 1861, by Augener (1927) , Knox & Cameron (1971) and Poore et al . (1975) . All this material has been examined and represents P. antipoda . Nilsson (1928) also described the species and examined some material from Port Phillip Bay housed in the Zoologisches Museum, Museum für Naturkunde der Humboldt- Universität, Berlin. According to Dr Neuhaus, the Curator responsible for polychaetes, the material has been lost, perhaps destroyed during the Second World War. As P. antipoda is widely distributed throughout Australian waters, the species needed to be fully described because the original description is brief. Three specimens of Pectinaria antipoda were found in the Natural History Museum in London. They were collected by Dr Robert von Lendenfeld, an Austrian sponge worker who visited Australia in the 1880s, and although he established a laboratory in Melbourne on the shores of Port Phillip Bay, he also travelled to Sydney. These three specimens were collected from Port Jackson several decades after Schmarda’s material was collected, although no detailed location within the harbour is given. During this period, little development occurred within the harbour, so we have assumed that environmental conditions were The distribution of the two species of Pectinaria in Sydney Harbour is not known. The harbour has a variety of habitats and the two species were never present in the same samples examined by us. Figure 9 . Pectinaria antipoda ( Schmarda, 1861 ) . Neotype (BMNH 1886.8.20.1). A, lateral view of anterior end. B, lateral view of posterior end. Scales = 2 mm. Pectinaria antipoda can be distinguished from the other two species of Pectinaria present in Australian waters, P. dodeka n.sp. and P. kanabinos n.sp. , both described in this paper, by the presence on the anteroventral lobe of chaetiger 2, ornamented with 12–19 papillae, which are absent in the other two Australian species. Only one other described species of Pectinaria , P. papillosa Caullery, 1944 , has such papillae ( Table 4 ). Material identified by Monro (1931) from Low Islands, Great Barrier Reef (BMNH 1931.7.1.61) as P. antipoda Schmarda, 1861 , was re-examined and identified as P. dodeka n.sp. (this paper). Material identified as P. antipoda by Stephenson et al . (1974) from Moreton Bay was reexamined and consisted of both P. antipoda and P. dodeka n.sp. Material identified by Hartmann-Schröder (1979) as P. cf. antipoda has been re-examined and although the material is in poor condition, especially in the region of chaetiger 2, we believe that it is P. antipoda .

C, lateral view of two neurochaetae from 6th uncinigerous segment. Scales = 100 µm. Distribution . Widely distributed south from Broome, Western Australia around southern Australia and along the eastern coast to Heron Island, Queensland ( Fig. 13 ). Habitat . Recorded from low water mark to 92 m , in sediments ranging from mud, silty sand to sand, and occasionally in Posidonia seagrass beds.
