FORAMINIFEEA OF THE ATLANTIC OCEAN. 15 



Globigerina bulloides, "arctic variety," H. B. Brady, Ann. Mag. Nat. Hist.,

 Globigerina bulloides D'Orbigny, var. borealis H. B. Brady, Proc. Roy. 



Soc. Edinb., vol. 11, 1882, p. 716. 



Description. — Test coiled in a depressed spire, the general form 

 subglobular, the last-formed volution consisting of four chambers, 

 the sutures somewhat depressed; aperture an arched opening along 

 the ventral margin of the inner face of the last-formed chamber. 



Diameter up to 0.30 mm. 



Distribution. — This species is an arctic one so far as published 

 records show. According to Brady it is common within the Arctic 

 Circle, but occurs only in bottom dredgings, not in the pelagic gather- 

 ings. Pearcey records it from the Faroe Channel, and Heron-Allen 

 and Earland from a single station west' of Scotland and in the Clare 

 Island region. I have failed to find it even in the colder areas along 

 the northeastern coast of the United States. Pearcey records it 

 from the Antarctic. Egger records it from numerous stations in 

 various parts of the world, and there are a few other scattered rec- 

 ords, but it may be questioned as to whether it really occurs in its 

 typical form except in the arctic or subarctic regions, with occasional 

 occurrences in cold waters somewhat farther south.
