FORAMINIFERA OF THE SCOTTISH NATIONAL ANTARCTIC EXPEDITION. 153 



Discorbina rarescens, H. 15. Brady. 

 A few specimens also obtained at Station 346. 



Discorbina concinna, H. B. Brady. 

 This species was also taken (rare) at Station 346. 



Discorbina parisiensis (d'Orbigny). 



Obtained sparingly at Station 346. It was collected in abundance by the 

 Challenger off Kerguelen, 20 to 50 fathoms. D. parisiensis is also recorded from 

 off the Irish coast, and the Atlantic shores of France. 



Genus TRUNCATULINA, d'Orbigny. 



Truncatulina tenera, H. B. Brady. 



This rare little form was obtained from the deposits taken at Stations 342, 417, 

 451, 459, and 467. T. tenera would appear to prefer the deep water of the great ocean 

 basins. Its other known localities are one station in the North Atlantic, off the 

 Canaries, 620 fathoms ; and three in the South Pacific, near the coast of Chili and 

 Patagonia, 166 to L375 fathoms. 



Truncatulina pygm&a, Hantken. 



Obtained (few) at Stations 300, 342, 420, 447, 459, and 467. T. pygmaea 

 is a typical deep-sea species ; it has been taken in the deposits from all the great ocean 

 basins, whenever they have been examined for Foraminifera, down to 3125 fathoms. 



The Scotia records are the most southerly points from which this species has been 

 collected. 



Truncatulina wuellerstorfi (Sch wager). 



This species occurred sparingly at Stations 300, 417, 420, and 421. T. wuellers- 

 torf, is a common form in the deep-sea oozes all over the great oceans. 



Truncatulina ungeriana (d'Orbigny). 



This species was found sparingly at Stations 313, 1775 fathoms, and 467, 

 2645 fathoms. 



Truncatulina lobatula (Walker and Jacob). 



This most common and widely distributed species I have obtained sparingly at 

 Stations 342, 346, 447, 451, 459, and 467. 



Truncatulina dutemplei (d'Orbigny). 

 Taken sparingly at Stations 342, 1946 fathoms, and 459, 1995 fathoms.
