 bers coiled, later ones uncoiled in a slightly curved series, all except 

 the last two or three with a thin marginal carina, the last two or three 

 chambers becoming inflated, nearly round in transverse section, well 

 separated from one another, the last-formed one especially so; 

 earliest portion with an irregular ornamentation consisting of numer- 

 ous bosses or anastomosing costae; the remainder of the test with 

 a few angled costae becoming often more numerous on the last-formed 

 chamber; apertural slightly extended, aperture radiate. 



Length 2 to 2,5 mm. 



Distribution. — Type specimen (U.S.N.M. No. 14748), from Albatross 

 station D5220, between Marinduque and Luzon, 50 fathoms (91 

 meters) . 



It has also occurred at station D5217, between Burias and Luzon, 

 105 fathoms (193 meters), bottom temperature, 63.1° F. (17.2° C). 



This is a common species, especially at D5220, where numerous
