FORAMINIFERA OF THE ATLANTIC OCEAN.

into an elongate neck; wall of the test with numerous fine longitu- 

 dinal costae, as many as 50 or 60 in number, running from the base 

 of the chamber to the base of the neck. 



Length up to 0.50 mm. 



Distribution. — This was originally described by Williamson as 

 Lagena suhstnata^ but later has been placed under Lagena striata 

 (D'Orbigny) as a synonym. The original figure of D'Orbigny for 

 Oolina stnata shows a test with the body about as long as broad, 

 very different in shape from that figured by Williamson. An exam- 

 ination of British bottom samples seems to show that this typical 

 form figured by Williamson is common about the British Isles, and 

 while it may vary to a certain extent, it seems as though it might be 

 recognized as a valid species. I have had a single specimen from 

 Albatross station D2035, off the northeastern coast of the United 

 States, which seems identical with British specimens, but it has not- 

 occurred elsewhere in the western Atlantic collections of the Alba- 

 tross, so far as I have seen. It is evidently included by many British, 

 authors under the name Lagena striata (D'Orbigny).
