COPEPODA

as shown by the N ioo H nets, towed horizontally at the surface, and approximately at 

 60 and 120 m., is shown in Fig. 75. Very few were taken between South Georgia and 

 the Falkland Islands. As its name implies, it is a true Antarctic species; Farran (1929) 

 in his report on the Terra Nova collections writes that it is " common from the Antarctic 

 Circle southwards". It occurred in water of both Bellingshausen Sea and Weddell Sea 

 origin, and was taken in the largest numbers in March 1926. 



A study of the N 100 H net results revealed evidence of a distinct vertical migration — 

 this is described and illustrated on pp. 236 and 247. One of the consecutive net series, 

 described on p. 254, showed that it is somewhat patchy in its distribution. 



In addition to the ' Terra Nova ' referred to above, it was taken in the Antarctic by the 

 Belgica, 1 Pourquoi-Pas?, 2 Gauss 3 and Aurora 4 Expeditions.
