FOKAMINIFERA OF THE ATLANTIC OCEAN.

Anticosti, and off Newfoundland. There are a few scattered records 

 for it outside the At hint ic. 



The specimens reach a large size and where complete show a very 

 distinct apertural end which is very slender and therefore very 

 easily broken. The opposite end is drawn out into a long spinose 

 projection which in perfect specimens is closed, but it easily becomes 

 broken. The majority of specimens therefore are similar to those 

 figured by Parker and Jones, showing the two ends open. I have 

 already noted under tliis genus that I do not think any of the typical 

 Lagenae have the two ends of the test open in perfect specimens.
