Of the remaining 14 fish, 11 were taicen in 1913, 1 in 1914, and 2 in 1916. A 

 male, of 34-40'7 cnu, and " nearly ripe," was caught in January, after 508 days, 

 at Aberdeen Bank, south-east of Aberdeen, at a distance of 72 miles. Two were 

 caught close together in February, after 527 days, at Aberdeen Bank, at distances 

 of 66 and 67 miles. One was a male, measuring 34-36"2 cm., and it was "ripe." 

 In the other, the sex was not determined, but, as it measured 33'5-37"9 cm., and 

 was " spawning," it was probably a female. Three were recaptured in March, a 

 female of 37"5-44"l cm., and " immature," after 551 days, to the east of May Isle, 

 at a distance of 24 miles ; another female, of 33"5-39"9 cm., and also " immature," 

 was taken, after 571 days, at Aberdeen Bank, at a distance of 62 miles ; and a 

 male, of 32"5-36"4 cm., not far from it, at a distance, of 65 miles, after 567 days ; 

 the condition of the testes was not recorded. A male, measuring 31-36*8 cm., 

 was caught in April 1913, after 592 days, off Largo, in the Firth of Forth ; it wa;^ 

 "immature." One of unknown sex was recaptured in May 1913, after 623 days, 

 close to Buchanness, at a distance of 92 miles ; it measured 33"5-4r2 cm., and was 

 "immature." In Jime, a female, of 35-39'7 cm., and "spent," was taken, after 

 637 days, 15 miles to the east of the Bass Rock, and another, whose sex was un- 

 known, of 30"5-39-5 cm., was taken by the " Goldseeker," after 658 days, in the 

 Firth of Forth. In October, after 764 days, one of unknown sex was got almost 

 directly east, offshore, at a distance of 67 miles ; it was " immature." 



In FebruaT^^ 1914, a male measuring 34-39 cm., was taken 1221 miles to the 

 south-east of Whitby after 883 days ; it was described as " mature." 



The two remaining fishes were recovered in 1916, 1, a male, in January, measur- 

 ing 22'5-37'7 cm., and "spawning," was recaptured 21 miles off Flamborough 

 Head, at a distance of 161 miles, after 1604 days. In April, a female, measuring 

 28-44'2 cm., and described as "spent," was taken, after 1682 days, 51 miles to 

 the eastward, offshore. 



Distances travelled — 10 miles and under. — Nine fish, or 25" 7 per cent., were 

 recaptured at distances of from 2^ to 9| miles, the average being 6"8 miles, viz. 

 3 males (18'7 per cent.), with a mean distance of 4| miles, 5 females (35'7 per cent.), 

 with an average of 6*8 miles, and 1 of unknown sex, which travelled 9 J miles. They 

 were all found within the Firth of Forth, 4 off Largo, 1 off Ehe, 1 off Leven, 1 off 

 Pittenweem, and 1 off Grail, and 1 oft' Dysart. 



10 to 20 miles. — Four, or 11'4 per cent., were recaptured at distances between

 15J miles, and 1 of underterniined sex, 11 miles. Three were taken within the 

 Firth of Forth, 2 near Kirkcaldy, and 1 off Portobello. The female had moved 

 to the south and east, east of the Bass Rock. 



The number recaptured at distances under 20 miles was, therefore, 13, or 

 37" 1 per cent., viz. 5 males (39'5 per cent.), with an average of 8 miles, 6 females 

 (42'8 per cent.), with a mean of 7*9 miles, and 2 of undistinguished sex, with an 

 average of 10 miles. Ten were got within the Firth of Forth, and 3 outside it. 



20 to 50 miles. — Seven of the plaice, or 20 per cent., were recovered at distances 

 of from 24"5 to 43"5 miles, viz. 3 males (18-7 per cent.), with an average of 24-1 miles, 

 and 4 females (28'6 per cent.), with an average of 30"3 miles. One of the females 

 was taken 29 miles to the westwards, at Bo'ness, in the Firth of Forth ; another 

 female was recaptured 241 miles to the south and east ; 1 of the males was got also 

 24 miles to the south and east ; all the other fish were caught to the north and 

 east. 



50 to 100 miles. — Eleven, or 3L4 per cent., were taken at distances of from 51 

 to 92 miles, viz. 5 males (3r25 per cent.), with an average of 68 miles, 3 females 

 {2r4 per cent.), with an average of 57"3 miles, and 3 of unknown sex, with an 

 average distance of 75 miles. One female had gone directly east, a distance of 

 51 miles ; all the others were got to the north and east, 5 at Aberdeen Bank and 

 vicinity, at distances of from 58 to 72 miles ; 1 was taken to the north of Tod 

 Head, and 2 — a male and 1 of unknown sex — close to Buchanness, at distances of 

 78 and 92 miles respectively. One of unknown sex was taken at Aberdeen Bank, 

 at a distance of 66 miles, and another almost directly east (N. 88° E.) offshore, at 

 a distance of 67 miles. 



Over 100 miles. — Four fish, or 11-4 per cent., were got at distances of from 122 

 to 213 miles, namely, 3 males (18-7 percent.), with an average of 165"6 miles, and
