FORAMINIFERA OF THE ATLANTIC OCEAN.

the test 'straight or more often shghtly curved; wall com])osed of 

 angular quartz sand grains with a considerable amount of gray cement 

 between; apertural end slightly tapering, without a definite neck, the 

 aperture being an opening between three or more sand grains at the 

 end of the chamber. 



Length up to 2 mm. 



Distribution. — Type specimen (U.S.X.M, Xo. 10669) from Albatross 

 station D2458 in 89 fathoms (163 meters) north of the Grand Banks, 

 At this station such specimens were common. It also occurred at one 

 station off our southern Atlantic coast, and I have specimens from com- 

 paratively shallow water in Passamaquoddy Bay, Maine. 



The s]iecies is shorter, thicker, and fewer chambered than JR. scor- 

 piurus, the chambers fewer and longer than in R. pilulifer and different 

 in the material of the wall and in the number and sha])e of the cham- 

 bers from R. bilocularis. 



It seems to be a species of cold waters and moderate depths. 



Goes figures this species under the name of R. scorpiurus in the 

 reference noted above. Tlie specimens were from the Greenland 

 Sea in 35-215 meters and from the Skagerack in 250 meters.

fig. G. 



Description. — Test elongate, tapering, widest near the apertural 

 end, composed of a few chambers (4-6), subglobular or elliptical, wall 

 made of other foraminiferal tests, usually Globigerina, firmly cemented 

 by a yellowish gray cement, apertural end truncate with a small 

 aperture without a definite neck. 



Length up to 4 mm. 



Distribution. — Typical specimens from station D2550 off the north- 

 eastern coast of the United States in 1,081 fathoms (1,977 meters). 

 It has also occurred at other stations in the same region and was prob- 

 ably present but not recorded from still others.
