Southwest Atlantic: 1090410, 8/567, [54.55°S 27.208°W], 1135 m; 1090411, 8/570, [56.067°S 27.308°W], 933 m; 1090432, 9/714, [58.417°S 33.108°W], 1574 m; ex. 1090469, 4/134, [61.967°S 65.275°W], 275 m; 1090470, 4/ 141, [59.975°S 65.092°W], 915 m; ex. 1090471, 4/143, [60.05°S 65.225°W], 609 m. Southeast Pacific: 1013468, 17/34-80, [56.95°S 95.25°W], 625 m; 1090383, 5/280, [67.325°S 74.875°W], 2577 m; 1090447, 10/846, [57.658°S 74.708°W], 1866 m; 1090472, 5/318, [57.242°S 71.008°W], 262 m. Southwest Pacific: 1090455, 11/ 919, [68.392°S 114.483°W], 1007–1098 m. Eastern Indian: 1013492, 46/358, [62.18°S 114.75°W], 240– 290 m.

Remarks: This species is relatively common in the cold-water, temperate and even tropical regions of all the world’s oceans, including the Mediterranean Sea. In Antarctic waters it is found right up to the Antarctic Continent. It occurs in a wide range of depths but is more common in the 200–1000 m layer (Vinogradov et al. 1982 /96). The above records provide range extensions for the Antarctic Zone of the Southwest Atlantic, Eastern Indian Ocean and Pacific Sectors. As for the previous species, I could not find any previous records for the Southeast Pacific Sector, thus they are new records for that region, confirming the circumpolar distribution of this species.
