DISTRIBUTION OF YOUNG STAGES OF EUPHAUSIA SUPERBA 125 



Furcilia stages are to be found chiefly in offshore deeper water, and secondly that older 

 larvae, Furcilia 6 and adolescents, are not so restricted but come close to the island. 

 It should be noted, too, that there is an ordered arrangement in the occurrence of the 

 larvae. Up to the end of the year, that is until about the middle of the summer season, 

 only larvae and adolescents of the previous year class are obtained. In the new year 

 Calyptopis and early Furcilia appear, indicating that spawning must commence about 

 the end of the year. From March onwards later Furcilia are obtained but with 

 Calyptopis i still occurring.

The line of stations from South Georgia 

 to the South Sandwich Islands was made 

 immediately after the completion of the 

 South Georgia survey of January-Feb- 

 ruary 1930 described above. It will be 

 recalled that more larvae were taken dur- 

 ing this survey than in any of the others 

 carried out in that neighbourhood. This 

 abundance was increased at the stations 

 of the South Sandwich line. Larvae were 

 taken at each of the six stations where the 

 70-cm. vertical nets were fished, and at 

 most of these the numbers were greatly in 

 excess of those in the net hauls of the 

 above-mentioned South Georgia survey. 



Sts. 360, 361 and 362 were made be- 

 tween South Georgia and the northern- 

 most of the South Sandwich Group. At 

 St. 360 one each of Calyptopis 3 and 

 Furcilia i, 2, 3 and 6 were taken; at
