Table LXX 

 Showing the numbers of Antarctomysis maxima, Calanus simillimus, and Drepanopus 

 pectinatus taken at three depths at stations in ranges of high and low phytoplankton 

 values during the daylight hours of 0800-1600. Within each range of phytoplankton 

 values the hauls are arranged in order of stations of ascending phytoplankton values from 

 left to right. Except where indicated by footnote stations are taken in December and 

 January 



No sample. 



f = Station taken in May. 



* = Station taken in March.
