Of the remaining fisli recaptured, 3, all females, were taken in May, June, and 

 December 1912 ; 2, both females, in 1913, in May and June ; and 2 in January 

 and April 1914. Of the first group, none had migrated far — 1 for 34 miles north- 

 wards to the neighbourhood of Stonehaveii ; another north-west for 21 miles 

 to the neighbourhood of the Bell Kock ; the third for 5 miles to the south-east. 

 The 2 former were " immature," the latter was " nearly ripe." Both of the females 

 taken in 1913 had moved north and east ; 1, measuring 30-41-1 cm., was taken 

 in June, after 784 days, 85 miles distant, off Buchanness, and the other, which 

 measured 31-5-43 cm., had taken an unusual direction, and was captured in May, 

 after 746 days, about 174 miles N. 66° E., in 39 fathoms (Lat. 58° 12' N. ; long. 

 2° 8' E.), or about midway between Scotland and Norway. It was " spent." Both 

 the fish taken in 1914 had also migrated north and east ; 1, a female which measured 

 30-5-44-8 cm., was captured on 18th January, after 999 days, 59 miles distant, 

 off Aberdeen ; it was "nearly ripe." The other, a male, measuring 35-42-4 cm., 

 was recaptured on 2nd April, after 1073 days, 151 miles distant, off the mouth 

 of the Moray Firth, in 47 fathoms ; the condition of the testes was not ascertained. 

 With the exception of this male, all the fishes recaptured in 1913 and 1914 were 

 considerably under adult size on liberation, and probably did not begin to migrate 

 for a long time. For 1 fish, an adult male, no date of recapture is obtained.
