The fact that these hauls were obtained to the east of the island does not detract from this, as there was little phytoplankton in the Bellingshausen water to the west, so that the mixing with eastern Weddell Sea water may well have brought out the last Fig. 29.

On this survey, it will be remembered, the western Weddell Sea current was apparently at a minimum, and was almost certainly dissi- pated before it reached South Georgia, and all the surface water round South Georgia at that time was comparatively ' old ' and mixed. More recently Mr John's preliminary investigations of samples collected during 1931-2 confirm the possibility of Thalassio- thrix being transported to the neighbourhood of South Georgia in old surface water of Bellingshausen Sea origin. The next species in order of total abundance on the November 1930 survey was
