FORAMINIFERA OF THE SCOTTISH NATIONAL ANTARCTIC EXPEDITION. 137 



Seas it is found abundantly, in depths ranging from 89 to 145 fathoms; and it 

 has been taken in the North and South Atlantic, in 1900 to 2350 fathoms ; also in the 

 Pacific Ocean, in depths varying from 245 to 3125 fathoms. 



Trochammina (Haplophragmium) globigeriniformis (Parker and Jones). 



This species, one of the most beautifully constructed forms of the genus, has been 

 taken at six stations, viz. 313, 337a, 342, 417, 447, and 459, but nowhere common. 

 Trochammina globigeriniformis has a world-wide distribution and a great range of 

 depth, from Franz Josef Land, in the Arctic Seas, to the Antarctic Continent, in 

 depths ranging from 15 to 3950 fathoms, and is one of the commonest arenaceous 

 Foraminifera in the deeper waters of all the great ocean basins. 



Trochammina nitida, H. B. Brady. 



This rotaliform species is somewhat rare, but is easily identified from its congeners 

 by the complanate superior surface of the test and its even margin. Found at Stations 

 118 and 346, but not common. Known from as far north as Franz Josef Land to as 

 far south as off Prince Edward Island, in depths of from 50 to 1070 fathoms. 



Trochammina (Haplophragmium} turbinata (H. B. Brady). 



From Stations 300 and 447 (rare). Known from one station in the South Atlantic, 

 off Amboyna, and from eight stations in the Pacific (BRADY and CUSHMAN). Range 

 of depth, 66 to 2050 fathoms. 



Genus GLOBOTEXTULARIA, Eimer and Fiokert. 



Globotextulama (Haplophragmium} anceps (H. B. Brady). 



This characteristic wild-growing species was found at Station 342 only (rare). It is 

 known from Davis Straits, off Culebra Island, off the west coast of South America, and 

 from two stations in the North Pacific. Range of depth, 196 to 2200 fathoms. 



Genus AMMOCHILO.STOMA, Eimer and Fickert. 



Ammoclnlostoma (Trochammina) galeata (II. B. Brady). 



This rare, inconspicuous, but handsome form was found at one station only, No. 459 

 (rare). It is exclusively a deep-sea species, being known from a few localities only in 

 the North Atlantic, South Atlantic, and Pacific, at depths of from 1825 to 2750 fathoms. 



Ammochilostoma (Trochammina} pauciloculata (H. B. Brady). 



A few specimens of this brilliant little species were obtained from Stations 447 and 

 459 (rare). Recorded from all the great ocean basins, mainly from deep water in mid- 

 ocean, although its range is from 173 to 2395 fathoms.
