Eggs and larvjE of Ifrepanopsetta have a wide distribution, especially over the 

 banks. The ova are very often found together with cod eggs, and were especially 

 numerous on the first cruises. 



June 9 to June 15, Prmcess I gave 609 eggs + 5 larvae. 



August 3 to August 12, Princess II " 1 " +7 



May 29 to June 4, ^carfia I "1,089 " +7 " 



July 21 to July 29, Acadia II " 35 " +28 " 



To these should be added the hauls made by the ^o. 33, which contain ova of 

 Drepanopsetta in considerable quantities until July 10. The spawning time must 

 thus be regarded as over by middle of July, which is somewhat late in comparison with 

 the European waters. (In the North sea, spawning taken place from January to 

 May.) The ova of Drepanopsetta are very easily distinguishable by the large peri- 

 vitelline cavity, and by their considerable size.
