however, states 12 inches to be their maximum size (10 Report Scot. Fish. 

 Board, p. 240, table). The females on the other hand become much larger, 

 in our seas as large as 13 inches, according to investigations by Krgyer and 

 myself. 



This relation between the sexes, that the males are so exceedingly rare 

 and much smaller than the females, so that the mature females, c. 8 — 13 

 inches, are generally larger than the males ever become, is something quite 

 exceptional among our flat-fishes. Fulton states that both males and females 

 are able to breed with a length of 5 inches. 



The large specimens of Drepamopsetta platessoides, just as well as the 

 small ones, live on deep water; in the Cattegat, therefore, on the soft clay 

 deposits, and in our smaller seas on the mud deposits which are often co- 

 vered with decaying gostera, and rather stinking. Without becoming rare 

 this fish goes down as far as into the western part of the Baltic Sea. 



I do not feel sure at all that I have explained the annual series of this 

 species of fish correctly; to do so I had too few specimens both of the grown- 

 up fish and the quite small ones. 



The Turbot (Rhombus maximus). 



We have succeeded during these investigations in finding this year's fry 

 of Rhombus maximus in great numbers on shallow water where it fives 

 together with the young plaice, Rhombus lams, and Pleur. ftesus. 



Already before this I have observed the pelagic young ones, which are 

 considerably larger than most others of our pelagic young fiat-fishes. I have 

 seen these in the open Cattegat as well as in the harbours of this sea, and I 

 have seen them also in the Great and the Lesser Belt. They do not seem, 

 therefore, to be so exclusively dependent on a high salinity as the plaice are. 

 Tins year (1893) young ones of 1893, \/ 2 — 4 inches long, have been found in 

 multitudes on the shores of the Cattegat, in the Belts and the Sound, nay on 

 the Baltic shores of Lolland and Falster; even at Bornholm they have been 

 found in great numbers. All these places are situated on open shores; we 

 have not met with these little young ones in the fjords. This fry did not. 

 appear till the month of June and July and particularly in August — October, 

 which agrees very well with the fact that the spawning-season of Rhombus 

 maxim-us occurs in the months of May — July in our seas; in October they 

 had reached a length of 1 — c. 4 inches. (See table XV.)
