Vertical distribution of every gathering of krill eggs recorded in vertical nets in shelf and oceanic water. Among the very large series of vertical net samples analysed since Eraser's work was published we found, as Fraser found, only one that yielded eggs in any real measure of abundance. This was at Station 2594 in the eastern part of the Weddell drift where the deep 1500-0 m. net, which as already mentioned (p. 100) I presume must have fished for some time in the cold bottom water, produced the very substantial total of 3444 eggs. The complete record of the occurrences of the eggs identified by Fraser, Fry and me is shown in Fig. 19 from which it will be seen that, apart from the notable exceptions provided by Stations 540 and 2594 and possibly also by Station 1283, the eggs for all practical purposes have never been encountered in anything other than negligible numbers. Our almost total failure to sample the enormous masses of them that must exist somewhere in the Antarctic seas is brought still closer to reality if one takes into account the very large number of occasions when during the long spawning season our nets were fished with negative results. For during that period, in the shelf and oceanic water of the East Wind-Weddell system, no fewer than 528 stations were made representing a grand total of approximately 2734 operations of the vertical net of which only 162, or just under 6 , were positive. Our failure, all but twice, to strike the eggs in mass, leaves an unfortunate blank in our data which perhaps for long will remain unfilled. It might be suggested, however, for the sake of future investiga- tion, that having regard to the vertical distr
