It certainly, for instance, does not seem to involve them in any very large-scale daily descent into the vv^arm current, and suggests too that such vertical movement as may be taking place, whether it be diurnal or not, is taking place in the main within the limits of the Antarctic surface layer. Owing to its being so consistently involved in the developmental ascent (p. 90, Tables 13 and 14) substantial numbers of First Calyptopes, as Table 15 shows, are seldom encountered free, even in the
