The positions of these surface stations are also shown in Text-fig. 37. At depths between 250-50 m., P. longicirrata was much more abundant, particularly in the deeper layers of the Antarctic Surface Water (Text-figs. 38-41), and was more generally distributed around the island. Hardy and Gunther recorded a similar picture. .WS 151(H) ⢠WS H9{H) ⢠WS 146(41. ~~ ISorr IB W )&-W r i ⢠300 (34) ⢠301 (22) â¢302 (24) 53 S S3 S â¢303 (72) â¢304(34) â¢-,â â¢J» .306 (!l) "323(14) ,._ ^ C V% .3" (4) ,'- >^' â¢357(13) â¢358(23) â¢313(7) J 1(69) â¢356 (25) . .354(I4)-J"(3II 1 f â ; 3S3 (39) 53'5 55° S 55 S 024 (30)' -⢠' ,' ,--^ ⢠337(122] \ â¢336(18) \ â¢33S(I0) â¢334(22) 1 1 ⢠344 (30) â¢343 (5) â¢342(35) 55" S 38 w ) Fig. 42 Fig. 43 Text-figs. 42-43.

January-February 1930. * = \ sample sorted. P. longicirrata was fairly evenly distributed around South Georgia at depths between 250- 1000 m., below which nets were not used (Text-figs. 42, 43). In the summer months, its occurrence in the deeper layers gives much the same picture of vertical distribution as that shown for the o° Line, but I have no evidence of its migration to depth in winter in the South Georgia area. P. longicirrata was also collected around South Georgia at Sts. 17 and 41 (Monro, 1936), and St. 1079; these records h
