FOEAMINIFERA OF THE ATLANTIC OCEAN. 



77 



Distribution. — The Atlantic records given by Brady for this species 

 include two stations off the West Indies; off Culebra Island, 390 

 fathoms (713 meters), off Sombrero Island, 450 fathoms (823 me- 

 ters), and also off Bermuda, 435 fathoms (796 meters). He also 

 records it from off the mouth of the Rio La Plata and off the Canary 

 Islands. Flint's specimens were from the northern part of the Gulf 

 of Mexico. I have had specimens in the Albatross collections from 

 the region of Cape Hatteras southward, off the coast of Florida and 

 in the Gulf of Mexico. Although it is recorded from the British 

 Isles, records are few and evidently specimens are very rare. 



Whether these are the same as the large species found in the 

 western tropical Atlantic it seems open to question. There are nu- 

 merous records for it in various parts of the indo-Pacific. There 

 is also a decided question as to whether or not our recent western 

 Atlantic species is really identical with that described by D'Orbigny 

 from the Tertiary of Italy. 



Nodosaria filiformis — Material examined. 



NODOSARIA CONSOBRINA (D'Orbigny). 



There are a few records, especially from the British Isles, under 

 this name. It is recorded by Balkwill and Wright ^^ as very rare 

 off Dublin and Wicklow, and again at a few stations in the same 

 region.^* Brady ^^ adds a record from the Durham coast, and Rob- 

 ertson^'' records it as rare, off the Island of Skye. Wright" gives 

 it as very rare at 7-1020 fathoms (13-1866 meters), off the southwest 

 of Ireland. The only record given by Heron-Allen and Earland is 

 off the west of Scotland, but specimens were not common.^^ I have 

 failed to find specimens in the western Atlantic material which, 

 could be referred to this species.
