Abstract
The study area lies within the geographical range of the so-called antiboreal South American (Eckman 1953), Magellanic (Balech 1954; Schilder 1956; Briggs 1974) or Magellanean (Antezana 1981) Province which extends from 42°S to the Antarctic Convergence along the channels of western South America, around its tip to Peninsula Valdes and along the east coast of South America, including the Falkland (Malvinas) Islands. The northern limits and districts of this Province, on the Pacific side, are not well established, according to authors who have studied the littoral (Hedgpeth 1969) and pelagic (Antezana 1981) faunas in this area. Based on the littoral fauna, Balech (1954) distinguished two districts: the chiloensis from 41°S to 51°S and the fuegensis from 51°S to the tip of South America. Antezana (op. cit.) recognized these two districts for the pelagic fauna as well, but proposed boundaries from 42–47°S and 47–60°S.
