FORAMINIFERA OF THE ATLANTIC OCEAN / 



There seems to be no authentic record of the species from the West- 

 ern Atlantic and it apparently has a Mediterranean and Indo-Pacific 

 distribution at the present time. A few specimens are referred to 

 N. houeana from the Coast of England by Heron-Allen and Earland. 

 Goes records it in his paper from 48° N. latitude and 10° W. longitude. 



Nonion scaphum (Fichtel and Moll) is very close to this species, and 

 in the Pliocene of Italy the two seem to merge one into the other. 

 *' Nautilus Jaba" Fichtel and Moll is also close to this species. It is 

 also from Rimini on the Adriatic and from the Pliocene of the Siena 

 region.
