OBTAINED BY THE S.Y. 'SCOTIA'

INTRODUCTORY NOTE 



IN February 1931, the R.R.S. 'WilHam Scoresby' ran a Une of stations, WS 542-55, 

 in the Weddell Sea between 10 and 20° W, reaching 68° 53' S at St. WS 552. The 

 resuhs were mainly hydrographical, but soundings were obtained at Sts. 552, 553, 555, 

 the Foraminifera from which were included in the Discovery Report (1934, x, pp. 1-208, 

 pis. i-x) on The Falklaiids Sector of the Antarctic {exchidiiig South Georgia). 



Apart from these scanty records, our knowledge of the bottom deposits of the Weddell 

 Sea rests on the material brought back by the late Dr W. S. Bruce, of the Scottish 

 National Antarctic Expedition in the S.Y. ' Scotia ', 1902-4. In the course of her cruise 

 the ' Scotia ' penetrated to the Coats Land coast of the Antarctic Continent in 74° 01' S, 

 and made several lines of stations traversing the Weddell Sea between the meridians 

 10° and 45° W. A report on the nature of the deep sea deposits was made by Mr Harvey 

 Pirie (P. 1905, DSD), and the Foraminifera were described by the late F. G. Pearcey 

 (P. 1914, SNA). 



When I was preparing Part III of the Report on Discovery Foraminifera, it became a 

 matter of some importance to examine the new types described by Pearcey. But in 

 spite of inquiry pursued in all likely quarters these were not discoverable (see E, 1934, 

 A, p. 12), a fact which now seems even more regrettable than I then regarded it. 



While making inquiry on the subject at the Royal Scottish Museum, Edinburgh, 

 vv^here the Bruce collections are preserved, I learned from Dr A. C. Stephen that the 

 Museum still had a quantity of sounding deposits brought back by the ' Scotia '. As my 

 Discovery report was already in proof nothing could then be done in the matter, but 

 after publication it seemed desirable if possible to reconstitute the missing types, and 

 with the Director's approval, the whole of the material was placed at my disposal. It 

 included deposits from three stations, 118, 451, 459, which lie outside the Antarctic 

 convergence line. These are marked with an asterisk in the subjoined list of material 

 received. They have been disregarded in the preparation of the following report, which 

 is confined to stations within the convergence. The letter P in the list indicates a station 

 at which Pearcey recorded the presence of Foraminifera, but it is not known whether 

 he examined material from the other stations also. From the fact that the stations not
