Fig. 6. Four-hourly vertical distribution of the First Calyp topis at all stations in deep oceanic water where more than one 

 Metanauplius occurred, the First Calyptopis in black, the Metanauplius in outline. The numbers of Calyptopes (C) and 

 Metanauplii (M) recorded at each station are given in the catch-table below, the figures being actual catch-figures not 

 corrected for length of haul.

Fig. 7. Four-hourly vertical distribution of the First Calyptopis at other stations, including shelf stations, where Nauplii 

 or Metanauplii occurred, the shaded portions in the lower part of the diagram indicating the approximate position of the 

 bottom in relation to the deepest observations in shelf water. The Nauplii or Metanauplii are here distinguished from the 

 Calyptopes by the figures enclosed in squares.
