Remarks. This species was described from a single specimen taken off the South Shetland Islands, and I added data from three more from that area and the Weddell Sea (Anderson, 1988). The new material considerably increases knowledge of the species in characters, size (to 264 mm SL) and depth range (491-1120 m). Two gravid females are among the present sample, both in SAM 34534; one, at 180 mm SL had 35 ova 2.34.1 mm in diameter, the other, at 194 mm SL had ripening ova 0.9-2.0 mm in diameter. The smallest male, at 176 mm SL, had mature testes. The largest male, at 264 mm (RUSI 53455), exhibits secondary male characteristics found in a few
