For 1903 \ve have, from Denmark, no such detailed investigalions into 

 the distri))utioo of the l'rv of i)laice as we have from 1902; but the fry 

 has beeu seen as far down as the southern end of the Great Belt, and wheu 

 we compare tliis with the results of the German investigations, the limits 

 for the occurrence of the fry must l^e supposed to have been about the 

 same as in 1902. At Bornholm I found no 0-group at all, in spite of 

 thorough investigation. Ehrenlattm, in 1903, found the 0-grou[> at Eckern- 

 førde, and Kriiyer in Kielerfjord (Laboe), Trawemiiude, Waruemiinde, Imt 

 not at Biigen (Barhoft). 



In 1893, as will be seen from "Report of the Danish Biological Station, 

 IV ", page 10, the occurrence of thé fry in the Cattegat and aloug the 

 shores of Funen and Zealand as far as Bornholm was investigated at some 

 50 — 60 stations. If we draw a line from Vejle in Jutland to the uorth- 

 most jioint of Langeland and from this place to Cojienhagen (cmp. the map, 

 p. 8), all the stations where the fry occurred in large numbers are situated 

 north of this line. On the western shores of Funen it was very scarce, 

 and was found at one station only, although there are 3 stations liere. At 

 Fænø in the Little Belt there was none; on the eastern shore of Falster we 

 found one, 2 inches long; and at Kjøge, in East Zealand, on the 16. of 

 August, we found two, 31/4 — 3V2 inches. At Bornholm we caught three, in 

 September, 2 — 274 inches long (1. c. 105 — 108); Apsfein, however, did not 



i. e. a seine the meshes of which are 1 inch from knot to knot.
