Variations in the quantities of the predominant plankton organisms on Records 23 and 24. Except for Copepoda the relative abundance of organisms is shown by a scale of + signs: +, ++, + + + .... except for a few miles at the beginning of the renewed run. Copepoda were absent from record 24 and all but absent from the dense phytoplankton zones at the beginning and end of record 23 ; they were present, however, in fair numbers (see Fig. 12) in the region of poor phytoplankton over the greater part of record 23. To what extent does this dis- tribution support the inverse relationship between zoo- and phytoplankton discussed by the author in the former report (Hardy and Gunther, 1935)? Can the reduced num- ber of Copepoda in the zones of dense phytoplankton be entirely due to the loss of filtration by the silk becoming clogged with the diatoms? To some extent this must.
