PORAMINIFERA OF THE ATLANTIC OCEAN. 



11 



tests of other foraminifera, surface more or less irregular, interior 

 fairly smooth, with a yellowish brown cement; aperture at the end 

 of a short tubular neck. 



Length up to 2.5 mm. 



Distrihution. — The type station from which Flint described this 

 species is Albatross D2679, off Cape Fear. At this station it is very 

 common. It has occurred somewhat farther northeastward and in 

 the Gulf of Mexico, but nowhere in such numbere as at the type 

 station. 



Occasional specimens at the type station show traces of a very 

 small third chamber of the same shape as in ordinary specimens, 

 but the two-chambered specimens are the rule in the great majority 

 of cases. From other specimens that I have seen this seems to have 

 a rather wide distribution, occurring in some numbers in the western 

 Pacific. I recorded the species in the North Pacific just north of 

 Guam. 



This may be one of those Indo-Pacific species which reaches 

 eastward into the Gulf of Mexico and adjacent portions of the western 

 Atlantic

DescrijMon. — Test elongate, somewhat compressed, chambers 

 well separated; walls composed of minute flakes of mica attached 

 to a chitinous membrane, whole test flexible when moist, but very 

 fragile when dry. 



Distrihition. — This species seems to be a common one about the 

 British Isles in comparatively shallow water on muddy bottoms. 

 Heron- Allen and Earland record it from 10 stations in the Clare
