(6) Bransfield Strait surveys 



(a) Survey of November 1929 (Sts. WS 476-493). Fig. 52. 



Eggs were taken at several stations in this survey. They were in greatest abundance between King 

 George Island and Trinity Land, where eighty-three are recorded from St. WS 480 at depths be- 

 tween 100 and 500 m.; at St. WS 477 there was one egg between 1000 and 500 m. At each of the 

 stations in the middle line between Livingston and Astrolabe Islands eggs were taken in very small 

 quantity, never more than five at any one station, in nets fishing between 250 and 950 m. None were 

 found in the Smith Island to Brabant Island line, but four Nauplius 2 were recorded, one at St. 

 WS 480 and the remainder in the middle line. 



(b) Survey of December 1930 (Sts. 537-555)- Fig- 53- 



Eggs were taken at all the stations on the east line from Elephant Island towards Joinville and at the 

 northernmost and southernmost but one of the King George Island to Trinity Land line. Nothing is 

 recorded from any of the stations in the western line from Snow Island to Trinity Island. 



(c) Survey of February 1929 (Sts. WS 382-399). Fig. 54. 



Only four eggs were taken in this survey, three of them in two stations on the King George Island 

 line and one at St. WS 394 in the vicinity of Deception Island. 



{d) Survey of February-March 1927 (Sts. 171-177). 



There was only one vertical net station near Cape Melville, King George Island, at which a 

 Furcilia i was recorded. 



(e) Survey of March 193 1 (Sts. 639 and 644). Fig. 54 (inset). 



St. 639, situated about midway between the South Orkney Islands and Joinville Island, yielded 

 Metanauplii, the three Calyptopis stages and Furcilia 2. It was at this station that the Metanauplii, 

 two in number, were found in the surface net. Calyptopis i predominated, there being 218 out of 

 a total of 293 larvae. 



At St. 644 near Elephant Island two days later, ten eggs only were taken. 



(/) Survey of March-April 1927 (Sts. 193-209). Fig. 55. 



At St. 193 at the west end of the Bransfield Strait between Smith and Trinity Islands, 120 larvae 

 were taken with Calyptopis 3 predominating and Calyptopis 2 and Furcilia i also present. 



There were 189 larvae taken at St. 194, with Calyptopis 3 again predominating, and Calyptopis 

 and 2, and Furcilia i and 3 present. 



At St. 196, off King George Island, only two Furcilia 4 were taken; at St. 197 thirty-two larvae 

 were taken in which Calyptopis 2 and 3 and Furcilia i, 2 and 3 were represented, Calyptopis 3 and 

 Furcilia 3 were most prominent. At St. 198 there were eighty-seven larvae with Calyptopis 2 and 3 

 prominent and Calyptopis i and Furcilia i, 2, 3 and 4 present. There were fifty-nine larvae at St. 199 

 including Calyptopis 2 and 3 and Furcilia 2, 3 and 4, with Furcilia 3 the most prominent. At St. 200, 

 the last station on the King George Island line, three Furcilia i and 2 were taken.
