Material examined. 1 female without oostegites, body length 8.5 mm , station TD-4, 39°27.08'– 39°29.15'N – 143°37.79'– 143°38.52'E , depth 3272–3146 metres, 4m ORE BT, 26 September 2001 . Remarks : Peraeospinosus magnificus has been described by Kudinova-Pasternak (1970) from the Kurile-Kamchatka Trench. The present survey brings the second record of the species, this time from the Japan Trench. The species has been further collected in other localities of Indian Ocean, North Pacific (off Japan , Alaska), South Atlantic and in the West Antarctic ( Fig. 10 ). Genus: Torquella (Bła ż ewicz-Paszkowycz, 2007) Diagnosis (after BłaŻewicz-Paszkowycz, 2007 ): Body elongate, at least eight to nine times as long as wide. Pleon short, less than 20 % of total body length. Pereonite 1 anterior edge highly concave. Mandible molar process with well calcified and serrated edge, occasionally with teeth. Maxilliped basis with seta at least as long as three-quarters of endites; endite distal margin with two tubercles and usually one seta. Cheliped basis posterior margin separated from pereonite 1 by gap. Chela slim, little longer than cheliped carpus. Pereopods 2 and 3 with spiniform setae on carpus, usually with long ventral seta on propodus and occasionally with rod setae on merus or carpus. Pereopods 4–6 unguis simple, with row of spines ventrally; prickly tubercles large (half as long as carpus), surrounded by row of spines. Uropods rami two-articled; exopod usually reaching three-quarters of endopod; exopod distal article twice as long as proximal article. Male: Unknown.
