to the north and west, and only 1 to the south and east, 11 miles distant. Four 

 of the fislies (or 40 per cent.) were taken to the nortli and east, having migrated 

 northerly along the coast, the distances travelled ranging from 70 to 149 miles, 

 the mean being no less than 104 miles. One, a male, was caught on 21st January 

 1913, 149 miles away, off Kinnaird Head. Another, a female, was also got off 

 Kinnaird Head, 127 miles distant, on 12th January 1913. The condition of the 

 reproductive organ of the male was not determined, but, as it was 41-7 cm. in length, 

 it was probably " mature," or approaching maturity ; the female, a large fish of 

 64 cm., was " nearly ripe.' 



The characteristic of this quarter, especially obvious on tlie chart, was tlie 

 migration to the north. 



Fourth Quarter. — Nine fishes (or 11-8 per cent, of the total) were recaptured 

 in February, March, and April 1913. Five were females (9-3 per cent, of the total 

 females recaptured), and 4 (or 19 per cent.) were males. Of the total, 8 (or 88 per 

 cent.) were taken in the north, at distances varying from 8 to 115 miles, the average 

 being 58 miles. Only 1 was got to the south-west, at a distance of 5 miles, and 

 none to the north and west, or to the south and east. 



Altogether, 63 of the fishes (or 83 per cent.) were recaptured within 12 months 

 after liberation, 46 being females, 16 males, and 1 of undetermined sex. Par- 

 ticulars of recapture were ascertained for all but 1 of these. Twenty-two (35-5 per 

 cent.) moved north and east ; 6 (9-7 per cent.) went north and west ; 9 (14-5 per 

 cent.) south and east ; 23 (37-1 per cent.) south-west ; 1 (1*6 per cent.) directly 

 east ; and 1 went west.
