Sub-family SACGAMMININ^. 



Genus P.SAMMOSPH^RA, F. E. Schulze. 



Psammosphterafusca, F. E. Schulze. 



This would appear to be one of the commonest species of the Antarctic Seas, being 

 obtained by the Scotia at no less than nine stations. 286, 313, 337a, 342, 416, 417, 

 418, 420, and 468. It attains a larger size and is more abundant in the far south 

 stations on glacial deposits than in the Globigerina oozes. Psammosph&ra fusca has a 

 very wide distribution. It has been taken in shallow water oft" the coast of Norway 

 (120 fathoms), and in 40 to 60 fathoms off Loch Scavaig, Skye ; but its natural habitat is 

 evidently the abyssal depths of the great oceans, where it attains its highest development, 

 being known from several stations in the North Pacific, 1495 to 3026 fathoms; seven 

 stations in the South Atlantic, 150 to 2800 fathoms; and ten stations in the North 

 Atlantic, 440 to 2750 fathoms. 



Genus SOROSPH^RA, H. B. Brady. 

 Sorosphsera confusa, H. B. Brady. 



Several specimens of this colony- building form were obtained at Station 420. Hitherto 

 it has been recorded from the Rockall Bank, 630 fathoms ; off the Azores, 900 fathoms ; 

 the Faroe Channel, 542 fathoms ; and the middle of the North Pacific, 2900 fathoms. 

 It is therefore a wide extension of its range to have found it in the Weddell Sea. 



Genus SACCAMMINA, M. Bars. 

 Saccammina socialis, H. B. Brady. 



Several specimens of this rare species were obtained at Stations 313 and 420. 

 Known from the North Pacific, North Atlantic, and Faroe Channel. 



Saccammina sphserica, M. Sars. 



This species was obtained at five stations, 291, 301, 313, 417, and at 420, in con- 

 siderable numbers, of large size, and typical in all its characters. Recorded from the 

 North Atlantic (common) ; fjords of Norway ; Faroe Channel ; off the shores of Franz 

 Josef Land; North Pacific; and near the Antarctic Continent (Challenger], where 

 BRADY describes it as indistinguishable from the North Atlantic type. 



Genus PROTEONINA, Williamson. 

 Proteonina (Reophax) difflugiformis, H. B. Brady. 



This apparently world-wide species was taken at eleven of the Scotia's stations, viz. 

 118, 300, 337ci, 338, 342, 387, 447, 451, 459, 467, and 468. These vary in depth 

 from 2^ to 2645 fathoms, and include all the varieties of deposit obtained by the Scotia ; 

 but it is noteworthy that it was not obtained at any of the stations south of the circle.
