FORAMINIFERA OF THE ATLANTIC OCEAN 



19 



a single row, retral processes very few, usually not more than 5 or 7, 

 distinct, the inner ends of the sutures sht-like; wall thick, usually 

 opaque; aperture composed of several small, rounded openings at the 

 base of the apertural face. 



Diameter, 0.50 mm.; thickness, 0.23 mm. 



Williamson described and figured this variety which seems to be 

 identical on the two sides of the Atlantic. Most of his specimens were 

 from Scarborough, but he notes its occurrence as single specimens at 

 other stations. On the American side of the Atlantic, it is often com- 

 mon in the Albatross dredgings at some depths, but only in deep or 

 cold water, north of Hatteras along the continental shelf. Sherborn 

 indicates that this is the equivalent of E. arcticum, but it occurs very 

 much farther south than that species, is smaller, with fewer chambers, 

 and a single row of a few openings along the sutures.
