ZOOGEOGRAPHY 223 



Samples from N 70 V nets, other than those along the o° Line and around South Georgia and the 

 South Sandwich Islands, were not extensively examined. Only four miscellaneous records of 

 R. bongraini are reported here. These are from St. 12, N 70 V, 500-250 m. (1); St. 2296, N 70 B, 

 240-110 m. (3); St. 2300, N 100 B, 350-200 m. (1); St. 2322, N 100 H, 5-0 m. (1), and have been 

 plotted in Text-fig. 25. They confirm the suggestions made above. At St. 2322 the species was 

 collected in the Weddell Drift and the other records are from the upper layers of the Warm Deep 

 Water. The surface position of St. 12 was outside the influence of Weddell Drift and the net which 

 collected R. bongraini there fished in the Warm Deep Water.

Text-fig. 26. Occurrence of Rhynchonerella bongraini round South Georgia, December-January 1926-7, February-March 

 1928, and January-February 1930, N 70 V nets. Number of specimens at each station in brackets. 



Previous records. The only published records of R. bongraini from about the Greenwich Meridian 

 are those made between 1927 and 193 1 by the Norwegian Antarctic Expedition (Stop-Bowitz, 1949), 

 which collected the species at twelve stations, all south of the northern limit of Weddell Drift, from 

 hauls made between 400 m. and the surface. 



In 1 930 Monro reported R. bongraini from around the South Sandwich Islands at Sts. SS 33 and SS 53, 

 as R. fulgens, and in 1936 from St. WS 555 as Callizonella bongraini. Stop-Bowitz (1949) reported 

 this species (as Krohnia bongraini) from 57 48' S., 26 25' W., in a net hauled between 400 and 300 m. 



Apart from Hardy and Gunther's (1935) records of Rhynchonerella bongraini as 'Alciopid larvae' 

 discussed on page 192, this species has previously been reported from South Georgia only by the 

 Swedish Antarctic Expedition, 1901-3 (Stop-Bowitz, 1951). No details of depth are given for this 

 record. 



Augener (1929) reported R. bongraini (as Callizonella bongraini) from fifteen stations made in the 

 Weddell Sea, between 450 m. and the surface, by the Deutsche Siidpolar Expedition, 1911-12. On 

 the Norwegian Antarctic Expedition of 1927-31 it was collected at 59 59' S., 45 18' W. between 

 100-200 m., and at 58 09' S., 37 38' W. between 300 and 200 m. (Stop-Bowitz, 1949), apart from 

 the records already noted. The Swedish Antarctic Expedition, 190 1-3, also collected this species at 

 four other stations in the Antarctic zone, with nets fishing between 700 m. and the surface (Stop- 

 Bowitz, 1 951). These records support my suggestions on the distribution of R. bongraini as far as the 

 information given with them allows.
