FORAMINIFERA OF THE SCOTTISH NATIONAL ANTARCTIC EXPEDITION. 1019 



Lagena lucida, Williamson. 



A few specimens of this compressed variety of L. Isevigata were obtained from 

 Station 346, 56 fathoms. 



Lagena acuta (Reuss). 



Taken at Stations 342 (rare) and 346 (few). Lagena acuta, like the preceding 

 species, is found all over the world, ranging in depth from 2 to 3125 fathoms. 



Lagena staphyllearia (Schwager). 

 Obtained (rare) at Station 447 only. This species appears to be confined to the 

 deeper waters of the North and South Atlantic, whence it is recorded by the Challenger 

 as being obtained in 2200 to 2750 fathoms ; but in the Southern Ocean and South 

 Pacific it occurs in shallow water near the coast-line. 



Lagena marginata (Walker and Boys). 



This cosmopolitan species was found sparingly at Stations 342, 346, 459, and 468. 

 Its bathymetrical distribution is also very extensive ; it has been taken from the littoral 

 zone down to 3125 fathoms. 



Lagena semimarginata, Reuss. 

 Obtained at Stations 346, 459, and 468, sparingly. 



Lagena lagenoides, var. tenuistriata, H. B. Brady. 

 Also found (rare) at Station 346. 



Lagena formosa, Schwager. 



Obtained (very rare) at Station 417, 1410 fathoms. L. formosa is a typical deep- 

 sea species ; it was also collected near the Antarctic Continent by the Challenger 

 Expedition, in 1300 fathoms ; and in the North Atlantic Ocean in 2750 fathoms. 



Lagena trigonomarginata, Parker and Jones. 



Several specimens of this somewhat rare species were also obtained from Station 346 ; 

 it has been collected in the North Pacific at a depth of 2300 fathoms. 



Lagena qiiinquelatera, H. B. Brady. 



Found (rare) at Station 342, 1946 fathoms. This species is recorded from the 

 Challenger Expedition in the South Pacific, 2350 fathoms ; and from off" Marion (Prince 

 Edward) Island, Southern Ocean, in 50 to 150 fathoms. 



Lagena orhignyana (Seguenza). 

 Obtained (rare) at Stations 118, 346, 417, 447, 459, 467, and 468.
