rORAMINIFERA OF THE ATLANTIC OCEAN.

In the present oceans the genus has a wide distribution in both 

 deep and shallow water. As a fossil it seems to be largely confined 

 to the later Tertiary, from the Oligocene onward.

There are a great number of records for these two species from 

 widel}' separated regions. The figures in the Challenger Report 

 assigned to the latter of these includes several things, and it is diffi- 

 cult with records based on such an assemblage to place them without 

 access to the originals. Both species were originally described from 

 Tertiary deposits of Europe. I have not had specimens from the 

 western Atlantic that I could satisfactorily assign to either of them. 



VIKGULINA BRADYI, new species.

 Zoology, vol. 9, 1884, p. 415, pi. 52, figs. 9a-c [7, 8?]. 



Description. — Test elongate, very slighth^ compressed, fusiform or 

 somewhat tapering, initial end bluntly rounded, apertural end 

 rounded; chambers biserially arranged, but somewhat twisted on the 

 axis, comparatively few in number, inflated; sutures distinct, de- 

 pressed; wall smooth; aperture elongate oval, the inner end broadest 

 with a slight rim; color white. 



Length 0.7-0.8 mm. 



Dlstrihution.— Type-specimen (U.S.N.M. No. 16287) from Albatross 

 station D2568, in 1,781 fathoms (3,257 meters), southeast of Nan- 

 tucket. There are four other stations for this species in this same 

 general region, but it was not found to the southward. It is hard to 

 determine where Brady's figured specimens were from, so the species 

 must rest for the present on the records given here. A comparison 

 of this with the original figures of V. suhsquammosa given by Egger 

 will show how different this species is in its subcylindrical shape, 

 fewer chambers, and, in fact, in all its characters it is a very different 



Virgulina bradyi — material examined.
