ii8 DISCOVERY REPORTS 



(3) South Georgia to South Sandwich Islands. 



(4) Scotia Sea. 



(5) Drake Strait. 



(6) Bransfield Strait surveys. 



(7) Palmer Archipelago and Bellingshausen Sea. 



(8) East of South Georgia (ice-edge stations). 



(9) Weddell Sea. 



For each area the groups of observations have been arranged with reference to the 

 southern summer according to the time of year during which they were made and not in 

 strict chronological order. 



(i) Falkland Islands to South Georgia 



Stations Year Time of year 



{a) WS 251-256 1928 August 



{b) WS 314-320 1928 December 



(c) WS 137-143 1928 February 



(d) WS 518-526 1930 February-March

(a) August 1928 (Sts. WS 251-256). Fig. 34.* 



Only one larva was recorded at St. WS 255, west of the Shag Rocks: it was a Furcilia 6. 



(b) December 1928 (Sts. WS 314-320). Fig. 35. 

 No larvae were taken. 



(c) February 1928 (Sts. WS 137-143). Fig. 36. 



The first three stations were made in sub- Antarctic water; at the last of these, St. WS 139, four 

 Calyptopis were found in the 500-250 m. net in temperatures of 2-66-3-09° C. At the surface at this 

 station the temperature was 6-15° C. The larvae were carefully examined as it was considered unusual 

 to get E. siiperba to the north of the Antarctic convergence, but they were undoubtedly this species. 

 One Calyptopis i and one Calyptopis 2 were found at St. WS 141, 250-100 m., and one Calyptopis 3 

 at 500-250 m. 



(d) and (e) February-March 1930 and March 193 1 (Sts. WS 518-526 and 655-659). 

 Figs. 37 and 38. 



No E. superba. 



(/) April-May 1929 (Sts. WS 427-433). Fig. 39. 



Larvae were taken at the first station only, situated between the north-west end of South Georgia 

 and the Shag Rocks, and then only in small numbers, five in all representing Furcilia 3, 4 and 5. 



In the Falkland Islands-South Georgia region larvae occur, but in small quantity, 

 from the Antarctic convergence eastwards to South Georgia. A late Furcilia was ob- 

 tained early in the season and Calyptopis and early Furcilia after the new year in the 

 second half of the southern summer. 



* In this and in the subsequent distribution charts the larger circular marks indicate stations at which 

 krill was found. The smaller marks indicate stations where the nets under consideration were examined 

 with negative results.
