may be said of Humpbacks. The averages of the percentage catch in each area for the 

 whole period 1929-38 works out as follows: 



Area... 



II 



III 



IV 



V 



These figures do not mean very much except that Blue and Humpback whales are 

 disproportionately scarce in area II, which, as Hjort, Lie and Ruud have pointed out, 

 is the oldest of the four whaling grounds. 



Table 19 is derived from Table 12, p. 241, and shows for each area the number and 

 percentage of each species shot at by the ' William Scoresby ' (area I here being the new 

 area in the Bellingshausen Sea and not Hjort, Lie and Ruud's small area I around the 

 South Shetland Islands). Table 20 shows the proportions in which species have been 

 observed, and is drawn up from the same data as Table 17 except that those seen north 

 of 40 S (a small proportion) are omitted. It includes the provisional area VI to cover 

 the central Pacific sector.

in separate areas 



Table 20. Ratio of species by observation at sea in separate areas 

 ('certain' and 'probable' identifications included) 



In these two tables the data, divided as they are into the separate areas, become too 

 scanty for very reliable conclusions, and though the totals are not much different there
