FOEAMINIFEEA OF THE ATLANTIC OCEAN. 



19 



the Albatross dredgings such specimens have occurred at numerous sta- 

 tions along the eastern coast of the United States, a few in the Gulf 

 of Mexico, and one off Brazil. The published records give its occur- 

 rence in the Arctic and Antarctic, off Australia, the Arabian Sea, the 

 Malay region and the Sea of Okhotsk as well as other regions. If all 

 these are typical it certainly has a very wide distribution. Unfortu- 

 nately no figures are given in a majority of these cases and descriptive 

 notes are usuallv wanting.
