Each amended number is plotted in the mean position of depth for each particular haul. The effect is that the plotted numbers represent the relative density of the population per unit volume of water in that part of the column sampled in each haul. The actual numbers of specimens caught by each net are given in Appendix I.

The N 70 V samples from the o° Line collections were taken in three hydrological zones over a distance of approximately 2160 nautical miles and provide quantitative information on the distribution of the smaller polychaetes. In addition to the above samples material collected by N 100 B or N 70 B nets was examined from the following stations on the o° Line: 1148, 1772, 2010-2027; 1813, 1815, 2322 (see Appendix II).
