Truncatulina robertsoniana, H. B. Brady. 

 This handsome species (rare) was obtained at Station 451, 1741 fathoms. 



Truncatulina akoncriana (d'Orbigny). 



Obtained (rare) at Station 459, 1998 fathoms. This is a world- wide species, and is 

 often taken in very deep water. 



Truncatulina tumidula, H. B. Brady. 



Taken (rare) at Station 468, 2700 fathoms. This is a rare species, and has only 

 been collected at one other locality in the red clay south of the Canaries, from 

 2740 fathoms, where it was taken in fair numbers. 



Truncatulina haidingerii (d'Orbigny). 

 A few specimens of this species were found at Station 468. 



Truncatulina tenuimargo, H. B. Brady. 



Obtained sparingly at Station 417, 1410 fathoms, the most southerly record for 

 this species. 



Truncatulina variabilis, d'Orbigny. 



Taken (common) at Station 346, 56 fathoms. This wild-growing form is a common 

 species in the warmer waters of the sub-tropical and temperate seas, in shallow water ; 

 it has. however, been obtained in depths above 2000 fathoms. I have taken this species 

 as far north as the Faroe Channel. 



Truncatulina rostrata, H. B. Brady. 



A few specimens of this species were also obtained from Station 346. Its natural 

 habitat is in the shallow water in the vicinity of coral reefs and islands ; it has not 

 been obtained north of the tropics. 



Genus ANOMALINA, d'Orbigny. 



Anomalina polymorpha, Costa. 



Obtained (rare) at Stations 420, 2620 fathoms, and (few) 346, 56 fathoms. This 

 species was found by the Challenger off Marion (Prince Edward) Island, 50 to 150 

 fathoms ; at three stations in the North Atlantic, 390 to 450 fathoms ; and at three 

 points in the South Pacific, 210 to 410 fathoms. The Scotia records are therefore 

 the most southerly points known for this species. 



Anomalina grosserttgosa (Gumbel). 



Taken (rare) at Station 346, 56 fathoms.
