In other words this apparent March scarcity must be ascribed in part at least to the low sampling power of the vertical net. In April there is some indication of a spreading from Weddell West into the western part of Weddell Middle, although alternatively the three April occurrences in Weddell Middle might be ascribed to the local growth of a very small percentage of the substantial early Furcilia population (Fig. 90 and p. 325, Fig. 86) recorded there in March. Weddell East is barren except for two very small occurrences, both in late April. Both (p. 321, Fig. 82, Stations 1353 and 2344) can be ascribed to the local growth of the early Furcilias already recorded there. It is somewhat surprising, having regard to the position in March, that there are no even minor occurrences of late Furcilias in Weddell West in April, for as Fig. 82 shows the principal larval concentrations then consist in the main of early Furcilias or younger stages. Two alternatives might be put forward to explain this anomaly: (i) our nets simply through chance failed to strike the principal older concentrations or (2), and perhaps the more likely, our stations fell in a year (or years) when for some reason or other the larval development in Weddell West was more retarded than usual. It has already been shown (p. 319, Fig. 81) that there appears to be a direct correlation betwe
