Of the other fishes recaptured, 2 were taken in the remainder of 1913, 6 in 1914, 

 and 2 in 1915. 



Two females were taken in November 1913, one, 5| miles to the south, and the 

 other, described as " three-quarters ripe," north-east of Kinnaird Head, at a distance 

 of 56| miles to the north and east. A female was taken in January 1914, 8 miles 

 to the north and west ; it also was " three-quarters ripe." In February, a male, 

 described as "spawning," was taken 30| miles to the north and west. In March, 

 a female, " spent," was taken 9 miles to the north and west. In May, a female, 

 also "spent," was got 9J miles to the north and west ; in September, a female, 

 north-east of Rattray Head, 53 miles to the north and east ; and in October, a 

 female 3 miles to the south. 



In February 1915, after 882 days, a female, described as " spent," was taken
