Description. — Test elongate, tapering toward either end, com- 

 posed of numerous chambers, three making each whorl; chambers 

 compressed at two sides, making a decided angle in the middle and 

 making up a trifacial test, triangular in end view and section ; wall 

 more or less costate, usually the costae numerous and distinct; 

 aperture with a short tubular neck and with a phialine lip usually 

 more developed on the outer side. 



Length up to 1 mm. 



Distribution. — From the above synonymy it will be seen that this 

 species is apparently very widely distributed. Just how many of 

 the above references are to typical material it is impossible, without 

 a study of the originals, to really determine. In the Atlantic the 

 species is well developed and characteristic of the comparatively 

 shallow waters of western Europe. On the western side of the At- 

 lantic it is well developed and abundant only on the northeastern 

 coast of the United States, with scattered records in the colder 

 waters nearly as far south as Cape Hatteras. It is most abundant 

 in waters of 100-300 fathoms (183-549 meters) off the New Eng- 

 land coast, and to or beyond the Grand Banks. It is a thick-walled 

 form with somewhat rounded angles, differing in these particulars 

 from European material. 



The species is replaced in the warm tropical waters of the Gulf 

 of Mexico and Caribbean by another species, as it is in the Ter- 

 tiary of the Coastal Plain of the southeastern United States. It is
