a female, and 1 of unknown sex, wore recaptured in the Moray Firth, at distances 

 of from 105 to 117 miles ; the female was " ripe," one of the males " about ripe," 

 and the other "three-parts ripe " ; a male, "ripe," was taken west of the Orkiaey 

 Isles, at a distance of 146 miles ; a female, which had migrated 26 miles to the 

 north and west, was "spawning," and a male, found 22 miles to the south and 

 west, was " nearly ripe " ; the other 3 fish had moved distances of only 6, 7, and 

 8 miles respectively. Two males and 3 females were recovered in March. Two 

 of the females were taken in the Moray Firth, at distance? of about 93 and 108 

 miles ; in neither was the condition of the ovaries ascertained ; a male, " ripe," 

 was caught to the south-east of Auskerry, Orkneys, at a distance of 127 miles ; 

 another male, also " ripe," was got off Buchanness, at a distance of 32 miles to 

 the north and west ; and a female, " partly spent," at a distance of 10 miles to 

 the north and west. A male and a female were taken in April, the male, " spent," 

 at a distance of only 5 miles to the north and west ; the female, also " spent," 

 near the Pentland Skerries, 114 miles to the north and west. In May, a female, 

 " spent," was captured 52 miles to the north and east, off Rattray Point. Three 

 females and a male were taken in June, 1 female " spent," off Noss Head, 

 Moray Firth, at a distance of 98 miles ; another, 25 miles to the north and 

 east, off Buchanness ; and the third, 15 miles to the south and west ; the 

 male, off Auskerry, Orkneys, at a distance of 127 miles to the north and east. 

 Two females were recovered in August, both to th e north and east, 1 at a 

 distance of only 7-| miles, and the other offshore, south-east of Buchanness, at a 

 distance of 39 miles. A female was taken in September, 8 miles north-west from 

 Fair Isle, at a distance of 157 miles to the north and east. In October, another 

 female was got 9 miles south-east from Fair Isle, at a distance of 150 miles to the 

 north and east. In November, a female was caught 6i miles to the north and 

 west. In December, another female was taken 8 miles in the same direction ; both 

 were " nearly ripe." 



Two were recaptured in 1913, both in March, a female, offshore, north-east of 

 Kinnaird Head, at a distance of 77 miles to the north and east, and a male on the 

 north coast, 5 miles north of Sandside, at a distance of 148 miles north and west ; 

 the condition of the ovary of the female was not recorded ; the male was " spawn- 

 ing." 



Two males were recaptured in 1914, 1 in January, 8 miles to the north and 

 west, an the other in June. 10 miles south-east of Fair Isle, at a distance of 146 

 miles to the north and east ; the former was " three-quarters ripe," and the latter 

 " spent."
