may be culled grown-up; the largest one* are c. IS inches long. The males 

 are less numerous than the females and altogether somewhat smaller. 



1 have succeeded in finding only proportionally few soles smaller than 

 !• inches, so that I cannot with certainty speak of their growth and age; it 

 appears however from the table that the fry of the year in August — October 

 is from ',., — 2 inches long and lives mi the more shallow, sandy beaches 

 together with other young fiat-fishes. The spawning-season occurs in May, 

 June (and July), so that these little ones are very young. Specimens of 

 3 — 5 inches I have got at the same places in small numbers already in 

 the foresummer; they must have been born in the preceding year, and 

 are consequently c. f year old. 



I must suppose that, in analogy with several other fiat-fishes, 

 there must be one annual series more (between c. <> — f f inches in length), 

 before we reach the grown-up fish, and that the sole thus requires 3 years 

 to attain maturity. Where this series, the 2-group, lives I cannot tell; but it 

 must doubtless fie found in the Cattegat, most likely on deeper water. 



Little young soles, partly pelagic ones, have during these investigations 

 been found as far south as Kjerteminde and Fredericia; they were found only 

 in small numbers. Grown-up soles are in these parts, as on the whole out- 

 side the Cattegat, so rare that many old fishermen do not know them at all. 



On account of this scarce information of the younger series of the sole, 

 I am unable to decide whether the Cattegat contains a really independent 

 stock of soles, or whether, perhaps, it is quite dependent on the Skager Back 

 in that respect. 



Also from the English shores we have only scarce information of the 

 fry of the sole. Cunningham (loc. cit.) supposes that it is not so absolutely 

 dependent on the shore as for instance the fry of the plaice, which sup- 

 position seems to agree with my observations. On deeper water such fry 

 can more easily remain undiscovered by the investigations than on quite 

 shallow water, which perhaps is the reason why it is so scarce in the table. 



The red Sole (Solea Mm). 



4 specimens of the above-mentioned little species of the sole. l s / 4 — 3 

 inches long, were found among fry of >S'. vulgaris which in L884 I had 

 gathered at Frederikshavn.
