(3) The autumnal scarcity of late Furcilia dominants, which seems anomalous in view of the already well established existence of such dominants (p. 361, Fig. iii) in Weddell West in the latter part of March, is probably to be ascribed to the fact that the majority of our April observations in Weddell West were made in two seasons when there seems to have been a marked decline in the activity of the Antarctic bottom water resulting (p. 331) in a late arrival of deep larvae in Weddell West and a correspondingly late development to the older Furcilia state.
