In February, a female, measuring 31-5-33-2 cm., was taken, after 216 days, in 

 the same direction, at a distance of 27 miles. 



In March, 3 males were recaptured ; 1, measuring 29-5-30-4 cm., went to the 

 south shore of the Firth of Forth, being got, after 236 days, about half a mile from 

 Newhaven, a distance of 63 miles ; another male, of 27-29-6 cm., was also recaptured 

 in the Firth of Forth, after 239 days, on the north shore, to the east of Elie, at a 

 di tance of 44 miles ; both these fish were " immature " ; the third male had 

 migrated to the southwards, and was caught, after 252 days, 32 miles off Spurn 

 Point, at a distance of 187 miles ; its size on liberation was 34 cm., but neither the 

 size nor the condition of the testes was recorded on recapture. 



In this quarter, therefore, 5 fishes, or 12*8 per cent., were taken, 4 males and 1 

 female.

 2 (9-1 per cent.) south and east ; 7 (31-8 per cent.) south and west ; and 1 (4-5 per 

 cent.), directly west.
