328 THE FLOUNDEK FAMILY. 



number, besides specks ou the body posteriorly, occurred along 

 the ventral region. On the left side, only two were visible 

 along the dorsal line and a few scattered specks along the 

 ventral, as well as on the posterior part of the body. 



During the Trawling Expeditions various small specimens of 

 this species occurred from January to August, viz. from li in. 

 to 3-^ in. and without any special differentiation of the sizes 

 in the various months'. Holt^ subsequently procured small 

 forms in August off the West coast of Ireland, the smallest 

 being 27 nmi., roughly about 1 in., and the series ranging 

 to 45 mm.; he considered them to be the young of the year. 

 With these were a second series from 93 to 9-5 mm., that is, 

 between 3 and 4 inches. Holt considered them to be from 15 

 to 16 months old; while specimens of 181 and 214 0^1. from 

 Aran in April, were probably about 2 years old ; and one 

 300 mm. (12 inches) about 3 years and 3 months old. 



The Turbot. (Bothus maximm. Will.) 



The ripe eggs of this species were first procured on the 

 10th July, 1884, during the Trawling Expeditions, from a female 

 of 12 lbs. (Buckland estimated theif number at 14,000,000, in 

 one of 23 lbs., whereas Collett in one of 775 mm. (= 31 in.) 

 calculates their number to be 1,056,000.) Neither at that time, 

 nor in 1892, when Mr Holt found another ripe female on the 

 Pontoon at Grimsby, could a male be obtained. He subsequently, 

 however, succeeded in hatching them, and gave the first accu- 

 rate account^ of the larval fishes, though none lived more than 

 a few days after escaping from the egg. Recently, Dr Canu^ 

 who is carrying out fishery investigations for the French 

 (iovernment at the Marine Station of Boulogne-sur-Mer, has 

 been able to fertilize the eggs, and has given a brief note of the 

 development. The perseverance of Dr Fulton and the practical 

 skill of Mr Harald Dannevig at the Dunbar Hatchery of the 

 Fishery Board have at length made it possible to give a more
