Holotype: 3, 14.5 mm, NMV J1340 (not examined). Paratype: AM P24324 (examined). Type locality: Port Phillip Bay, Victoria, Australia, 38°19'S 144°47'E. <b>Material examined</b>. <b>New South Wales</b>: 3 adults, manca, AM P38673, Middle of Spring Cove, North Harbour, Port Jackson, baited trap, 15 m, S. Keable, D. Townsend, J. Lowry, 16–17 Jul. 1988; series from Bate Bay, Pioneer Cement / The Ecology Lab. EIS Study, AM P47277 –47281, baited trap, 1991: 100 specimens, S1R1 E deep; 3 specimens, S1R1 deep; 30 specimens, S2R1 deep; 97 specimens (2 vials), S1R2 E deep; same study off Providential Head, 62 m; series from Jervis Bay, CSIRO Baseline Studies, P. Hutchings <i>et al</i>. AM, corer, AM P47271 –47276; 1 specimen, site 4#5, 25 May, 1990; 1 specimen, site 4#2, 5 Jun. 1990; 5 mancas, site 6#3, Aug. 1989; manca, site 6#2, 5 Jun. 1989; manca, site 4#2, Jun. 1989; manca, site 6, Aug. 1989. <b>Diagnosis</b>. <i>Eyes</i>: vestigial. <i>Interocular furrow</i>: well developed, forming a ridge that runs across the cephalon and deflects anteriorly towards the midpoint. <i>Frontal lamina</i>: lateral margins straight, parallel. <i>Antenna</i>: c. 0.25× as long as body, reaching to posterior of pereonite 1. <i>Coxal plates</i>: furrows variously developed, strongly developed on pereonite 1 and coxae 2–3, absent on coxae 4–6, weakly developed on coxa 7. <i>Pleonite 4</i>: apex forming a broad acute point. <i>Pleotelson</i>: broad, length 0.83× basal width; anterodorsal depression absent; anterolateral margins almost straight and angling posteriorly toward the midline; posterolateral margins straight, markedly angled to anterolateral margins and meeting at an obtuse angle; apex not produced, lateral margins converging smoothly to a point; with 10–12 RS. <i>Pereopod 2</i>: propodus with 2 RS on palm. <i>Pereopod 3</i>: propodus without RS on palm. <i>Pereopod 7</i>: basis broad, width 0.55× length; distance between anterior margin and medial carina less than between posterior margin and medial carina; posterior margin with setae proximally and distally but not medially. <i>Penes</i>: absent. <i>Pleopod 2 appendix masculina</i>: extending subequal with tip of endopod, 0.96× length of endopod; slender; margins straight; apex bent laterally slightly, bluntly rounded. <i>Uropods</i>: exopod short, 0.75× the length of the endopod. <b>Size</b>. Adults to 18.6 mm. <b>Remarks</b>. The incomplete interocular furrow formed into a distinct ridge is sufficient to distinguish <i>Natatolana gorung</i> from all other species in the genus. <b>Distribution and ecology</b>. Australia: New South Wales: Port Jackson; off Sydney; Jervis Bay. Victoria: Port Phillip Bay. To depths of 66 m. Scavenger.
