FORAMINIFERA OF THE ATLANTIC OCEAN 



47 



The original specimens of Fichtel and Moll are recorded from the 

 Mediterranean and the Arabian Sea. There is much question as to 

 its occurrence in the Mediterranean, and it may be that the authors 

 had West Indian material from some source. The material from the 

 Red Sea that I was able to see in the Brady collection has certain 

 characters that seem to distinguish it from West Indian specimens. 

 In the western Atlantic there may be two living species in addition 

 to that often referred to as Orhiculina compressa d'Orbiguy which is 

 here included under Archaias. These species should all be studied 

 in detailed section and the relationships of the microspheric and 

 megalospheric forms determined. The species occurs fossil in the 

 West Indies, Panama, and Florida.
