The probable distribution of the dominant species over the area studied in late spring. southwards; and (ii) transportation of the aftermath of the increase farther south by surface currents may lead to an apparent increase later in the season in the more northerly part of the region studied. Round South Georgia it seems fairly certain (cf. p. 91) that the main increase takes place in late spring; in the Weddell Sea it appears to take place at mid-season, and in the Bellingshausen Sea (doubtless in the far south of the Weddell Sea also) even later—about the end of January. It should be realized that it is mainly to the more northerly parts of the region that these remarks apply—the South Georgia area, the Scotia Sea, and Bransfield Strait. Farther south seasonal data are scarce, owing to ice conditions, and it is probable that.
