FORAMINIFERA OF THE SCOTTISH NATIONAL ANTARCTIC EXPEDITION. 1015 



Bulimina elegantissima, d'Orbigny. 

 This species was obtained in abundance at Station 118, 24 fathoms. B. elegantissima 

 has been taken as far north as the west coast of Novaya Zemlya. It is also found on 

 the shores of the British Islands, Belgium, and France. It was taken by the Challenger 

 Expedition off the Falkland Islands in 6 fathoms; east coast of Australia, 2 to 410 

 fathoms ; South Pacific, 6 to 6 1 fathoms ; off the coast of South America, from Peru to 

 Cape Horn. 



Genus Virgulina, d'Orbigny. 



Virgulina pauciloculata, H. B. Brady, 



This minute species was obtained (sparingly) at Station 459, 1998 fathoms ; the only 

 other records are off the shores of New Guinea and the adjacent islands, in depths from 

 11 to 129 fathoms. 



Virgulina schreibersiana, Czjzek. 



This somewhat doubtful species has been taken at four Scotia stations, 417, 418, 

 467, and 468. Nowhere abundant. 



It has a very extensive distribution, and although it has been recorded from 

 shallow water, its natural habitat would appear to be in the deeper waters of the great 

 ocean basins; its range of depth is from 11 to 3125 fathoms. The Scotia's records are 

 the farthest south from which this species has been obtained. 



Sub-family CASSIDULININiE. 

 Genus Cassidulina, d'Orbigny. 



Cassidulina crassa, d'Orbigny. 



Obtained at Station 346, 56 fathoms (common) ; its distribution is world-wide, 

 from lat. 83° ll'N. to as far south as the Antarctic Continent, ranging in depth 

 from comparatively shallow water to the deepest water in mid-ocean. 



Cassidulina suhglohosa, H. B. Brady. 



This fine species was obtained at no less than nine stations, 118, 286, 313, 

 842, 417, 447, 459, 467, and 468, although it is not common at any of them. C. 

 suhglohosa is, generally speaking, a deep-sea type, and has been recorded from all the 

 great ocean basins. 



Cassidulina Isevigata, d'Orbigny. 



This species was obtained (few) at two stations, 118, 2j fathoms, and 451, 1741 

 fathoms. C. Isevigata is one of the commonest Arctic Foraminifera, and has a world- 

 wide distribution ; it was found as far south as the Antarctic Continent by the 

 Challenger Expedition. Its range of depth is from very shallow water, round the 

 British coast, to 1741 fathoms, in the Southern Ocean.
