yellow in color. Certainly it is not the form usually assigned to 

 Pulvinulma canariensis by later authors, and which should be known 

 as Globorotalia hirsuta (d'Orbigny). The peculiar placing of the cham- 

 bers with the median line radial instead of oblique, very lobulated 

 periphery, depressed, nonlimbate sutures and finely papillate surface, 

 with typically only four chambers in the final whorl, will distin- 

 guish this species. 



Its Atlantic distribution so far as the material examined shows is 

 a very definite one, from the coast of Carolina to the British Isles. 

 It is very abundant at a few Albatross stations, but is wanting at the 

 others. 



The many records for "Pulvinulina canariensis" should be checked 

 with the original material before being accepted.
