FORAMINIFERA OF THE SCOTTISH NATIONAL ANTARCTIC EXPEDITION. 121 



hitherto only been recorded from the Pacific Ocean ; its range of depth being from 

 56 (Scotia Station 346) to 2700 fathoms. 



Miliolina cin-tifnrix (Bornemann). 



A few specimens were found at Station 420, 2620 fathoms. These were all of 

 normal character, and showed no signs of their tests being diminished in thickness, as 

 might be expected at such a depth, where the deposit gave such a low percentage 

 of CaCOj. 



Miliolina oblonga (Montagu). 



Obtained sparingly at Stations 346 and 459. 



MilioUna hiifcitletita, H. B. Brady. 



This doubtful Triloculine form was found at three stations, 291, 313, and 420, but 

 was not common. This species is hitherto known only from the Arctic Seas and 

 North Atlantic, so far as I am aware. I have found it moderately common in the 

 Faroe Channel in 630 fathoms. It is therefore of interest to find it fairly well dis- 

 tributed in the Weddell Sea. 



Miliolina bucculenta, var. placentiformis, H. B. Brady. 



This variety I obtained (rare) in the material from Station 420, 2620 fathoms. 

 BRADY records it in his report on the Challenger Foraminifera from two widely 

 separate localities off Culebra Island, West Indies, 390 fathoms ; and Balfour Bay, 

 Kerguelen, 20 to 50 fathoms. 



Miliolina seminulum (Linne). 



This, the most common species of the genus Miliolina, has been found in all 

 localities from the most extreme point in the Arctic Seas to as far south as the edge 

 of the Antarctic ice, and from the tidal zone clown to 3000 fathoms. It was, 

 however, obtained only at one Scotia station, viz. 346, 56 fathoms. 



Miliolina, fichteliana (d'Orbigny). 

 Obtained very sparingly at Station 468, 2645 fathoms. 



Miliolina trigonula (Lamarck). 

 Taken at Station 346, 56 fathoms (rare). 



Miliolina terquemiana, H. B. Brady. 



This triangular striated form, which is very rare, was obtained from the material 

 taken at Station 346, 56 fathoms ; the only other known localities for this species are 

 from shallow water off Ceylon, and in littoral sand on the east coast of Madagascar.
