General distribution of Diatomales (totals per loo-o m. haul), South Georgia survey, November 1930. This chart is based on catches made at the positions indicated in Fig. 19. The distribution of Chaetoceros socialis is shown in Fig. 19. It will be seen that it was taken at fourteen stations only, all of which were grouped round the southern extremity of the island, some close inshore, and the others in the neighbourhood in which the pack-ice lingered longest during this spring, and all in water which from the general nature of the phytoplankton as a whole, almost certainly originated in the western Weddell Sea. 7-2.
