FORAMINIFERA OF THE ATLANTIC OCEAN. 55 



Descnption.— Test flask-shaped, nearly circular in cross section, 

 body of test subglobular, neck variable in length, usually rather 

 abruptly contracted from the body of the test at its base; surface 

 ornamented with numerous rather fine costae running the entire 

 length of the test, apical end typically broadly rounded, occasionally 

 slightly tapering to a point. 



Length 0.25-0.75 mm. 



Distribution.— From the list of references it would seem that this 

 is a very widely distributed species. There are numerous records 

 for it about the British Isles and a few others from various parts 

 of the Atlantic, as well as in other regions. However, all the striate 

 Lagenae I have had from the western Atlantic seem to be better 

 placed under other species.

 DescHption.—'' Test oval, pyriform, or flask-shaped, and oithor 

 ecto- or entosolenian. It is decorated externally with tolerably stout 

 longitudinal costae, from 6 to 20 in number, bearing conspicuous 

 pseudopodial foramina. The perforations are placed either m single 

 rows down the middle of the costae or in double lines, one on each 

 side, in their thickened bases." 

 Length 0.30-0.50 mm. 



Distribution.— There are numerous records for this species off the 

 British Isles and in other parts of the Atlantic, off Spitzbergen,
