FORAMINIFERA OF THE ATLANTIC OCEAN. 



37 



Distribution. — The only Atlantic record given by Brady in the 

 Challenger Report is off the Cape Verde Islands, in 11 fathoms (20 

 meters). The only other record seems to be that of Heron- Allen 

 and Earland, a single specimen in Clew Bay, off western Ireland, 5^ 

 to 11 fathoms (9 to 20 meters). I have had two specimens which 

 may be referred to this species from the Albatross material. One of 

 these is off the coast of Florida in 5G fathoms (102 meters), the other 

 in 20 fathoms (37 meters) off the coast of Brazil. Most of the records 

 for this species are in the tropical Pacific, and it may be likely that 

 fm'ther study will show the Atlantic specimens to be distinct. 



Bolivina limbata — material examined. 



BOLIVINA LIMBATA H. B. Brady, var. COSTULATA Cushman. 



Bolivina limbata H. B. Brady, var. costulata Cushman, Publ. 311, Carnegie 

 Inst. Wash., p. 26, pi. .3, fig. 8. 



Description. — Variety differing from the typical form of the species 

 mainly in the addition of longitudinal costse, usually few in number, 

 and near the base of the test. The specimens are almost invariably 

 somewhat twisted as in the typical. 



Length of largest specimen 0.75 mm. 



Distribution. — All of the Tortugas specimens seem to be of this 

 variety. The typical form of the species does not seem to be common 

 in the Atlantic, the only records I have had being from off the coast 

 of South America. This species, however, is fairly common in the 

 Tortugas region as represented by this variety, and it may be found 

 to be common in the shallower waters of the tropical Atlantic.
