Material examined. New South Wales: Neutral Bay, Port Jackson , 33°50’42”S, 151°13’06”E, September 1908, AM G.11238, 1 specimen GoogleMaps ; AM W.7339, 1 specimen (previously examined by Day (1977) from same location. GoogleMaps

Type locality. Port Jackson , New South Wales .

Description. Large, stout worms, thoracic width 3.8 and 4.8 mm, length more than 70 mm, more than 200 segments ( Fig. 4A View FIGURE 4 ). Thorax flattened, abdomen cylindrical, segments very short ( Fig. 4 View FIGURE 4 A–E). Prostomium short conical with rounded tip ( Fig. 4B View FIGURE 4 ). Thoracic chaetigers numbering 20. Branchiae from chaetiger 7–8; short triangular on anterior thorax, then gradually lengthening; in abdomen becoming digitate, shorter than notopodial postchaetal lobe ( Fig. 4A, B, D, E, G View FIGURE 4 ). Thoracic postchaetal lobes developed from first chaetiger gradually increasing in size, both triangular in shape; neuropodial lobes all single, broader than notopodial; tips of each lobe forming round papillae ( Fig. 4C View FIGURE 4 ). No subpodal and stomach papillae. Abdominal notopodial lobes long and wide, foliaceous; abdominal neuropodial lobes bilobed with outer lobe slightly shorter than inner lobe; subpodal flange and notch not developed ( Fig. 4E, G View FIGURE 4 ). Chaetae crenulate capillaries in all parapodia; thoracic neuropodia bearing anterior row of curved weakly serrated uncini ( Fig. 4C, F View FIGURE 4 ). Forked chaetae in abdominal notopodia not observed. Pygidium without anal cirri.

Distribution. Australia, Queensland, New South Wales.

Habitat. Not known.

Remarks. The studied specimens agree with the previous descriptions. They have a characteristic appearance, with a large size and short segments. Due to these characteristics, several specimens of S. cylindrifer from the collection of the Australian Museum, which looked somewhat similar, had been incorrectly identified as Scoloplos novaehollandiae . These two species are easily distinguishable by the branched branchiae (at least on posterior segments) and uniramous abdominal neuropodia in S. cylindrifer , whereas S. novaehollandiae has simple branchiae and bilobed abdominal neuropodia with subequal lobes.
