An interesting feature of the record is the dense concentration of the larval Euphausiacea which occurred in the gap between the two patches of phyto- plankton. The significance of the inverse correlation between the phyto- and the zoo- plankton has been discussed at length by the author recently (in Hardy and Gunther, 1935). In this record it is impossible to decide whether the concentration of the euphausians is to be attributed to an exclusive influence of the phytoplankton or
