DISCOVERY REPORTS 



PTEROPODA 



Samples of the different species of Pteropod taken in our collections were sent to the 

 late Miss A. L. Massy, who kindly indentified them for us. She has written a report 

 (1932) upon all the Pteropods taken during the first two years of the Discovery investi- 

 gations. 



Cleodora sulcata (Pfeffer). This species was recorded at only four stations off the 

 north-east coast of South Georgia in March 1926, and at two stations, WS 69 and WS 

 70, across the line of Antarctic Convergence between South Georgia and the Falkland 

 Islands in February 1927. 



St. 12 (N 70 V) 1 at 500-250 m. St. WS 69 (N 100 H) 8 at 146 m. 



St. 36 (N 100 H) 4 at 90-0 m. St. WS 70 (N 100 H) 13 at 0-5 m. 



St. 37 (N 100 H) 27 at 90-0 m. 3 at 146 m. 

 St. 44 (N 100 H) 1 at 170-0 m. 



It has been taken in the Antarctic by the Belgica, 1 National Antarctic (Discovery), 2 

 Gauss 3 and Terra Nova 4 Expeditions; the ' Belgica ' taking it as far south as 70 33' S. 



Clione antarctica, E. A. Smith. Taken at a number of stations round South Georgia 

 during the December- January survey in 1926-7 and at stations between South Georgia 

 and the Falkland Islands in February 1927. 



It was usually taken near the surface or in the top 100 m., but it was found below 

 750 m. at St. 151 off the north-east coast of South Georgia and below 500 m. at Sts. WS 

 68-70 across the Antarctic Convergence, where the surface layer had dipped below the 

 sub-Antarctic surface water. It was not taken off South Georgia in March 1926 or 

 May 1927. 



The species is a true Antarctic form, and has
