Passage, the greater proportion by far of the total catch at nearly all stations occurred in 

 the lower nets. In the middle of the month of April 1932 there were three stations 

 (850, 851 and 853) at which an almost equal proportion of the catch occurred in the upper 

 and lower nets and another similar station (863) at the end of the month just south of

the convergence. At the six other stations taken during April almost the whole catch 

 occurred in the lower nets. In November 1932, however, the greater proportion of the 

 total catch was taken in the upper nets. The same condition was found throughout 

 December and also in February 1933, although two stations in that month taken in 

 the Drake Passage showed a majority in the lower nets, and at St. 1123, on the sub- 

 Antarctic side of the convergence in February between the Falklands and South Georgia, 

 the entire catch was in the lower nets. During the winter months the catches were 

 mostly too small to give reliable percentages : during May and June, however, the catches 

 were entirely or mainly in the lower nets (Table III c). There are no observations for
