returns, all from the north-west coast of Australia (Plate LXIII), but, it will be noticed, 

 none from the marking of the season 1934-35, f° r whaling was not carried on off this 

 coast in 1935. The following two seasons, 1936 and 1937, are both represented and 

 include marks fired on the Antarctic grounds during the seasons 1935-36 and 1936-37. 

 This evidence demonstrates clearly that the Humpbacks long known to pass along the 

 west and north-west coasts of the Australian continent during the southern winter have 

 actually come from the Antarctic seas between 80 and ioo° E. 



TABLE IV 

 Marked Humpback whales killed in each group 



The 1 -Group, which contains recoveries from five 1 whales, shows the return to the 

 Antarctic grounds in the southern summer complementary to the northward movement 

 shown by the i-Group (Plate LXIV). The four recoveries on the Queen Mary Land 

 ground after intervals varying between 330 and 393 days were all made at comparatively 

 short distances from the position of marking. In this group there is also a single recovery 

 to the south of Africa, and here the whale has been taken at a position quite near to 

 where it had been marked. 



1 Two marks (Nos. 2587, 2594) may be from the same whale ; if not, the number of whales in this group is
