Vertical nets were fished at Sts. 618, 620, 622, 624 and 629. At St. 618, the first station on this line, situated to the north-east of the South Orkneys, there were 985 larvae distributed from the surface down to 750-500 m. Calyptopis i predominated, but there were present also Metanauplii, deep down, and Calyptopis 2. At this station also an egg was found in the 250-100 m. sample. At St. 620, larvae, totalling 243,

Vertical nets were fished at Sts. 618, 620, 622, 624 and 629. At St. 618, the first station on this line, situated to the north-east of the South Orkneys, there were 985 larvae distributed from the surface down to 750-500 m. Calyptopis i predominated, but there were present also Metanauplii, deep down, and Calyptopis 2. At this station also an egg was found in the 250-100 m. sample. At St. 620, larvae, totalling 243, were found in all the nets down to 1000 m. with the exception of the 500-250 m. haul. Calyptopis i was again the most plentiful with few Calyptopis 2 and Meta- nauplii, the latter being entirely confined to the lowest nets. At St. 622 the number of larvae was much reduced, only forty-two being taken. With the exception of one Calyptopis 2 all were in the Calyptopis i stage. No Metanauplii were obtained at this station. At St. 624 only one larva, a Furcilia i, was obtained from the quarter sample of the 70-cm. net analysed. Ten Furcilia i, four Furciha 2 and one Furciha 3 were taken in the i-m. net. There were no larvae at St. 629, between the South Sandwich Islands and South Georgia. Of these stations, all up to St. 626 were taken in the proximity of the pack-ice edge.
