Description. — Test slightly compressed, rounded, the apertural 

 end slighth^ tapering, making the entire test a little longer than 

 broad ; chambers few ; sutures rather indistinct ; surface ornamented 

 by numerous subspinose projections; aperture radiate. 



Length up to 0.60 mm. 



Distrihution. — I have had specimens from two Albatross stations, 

 one off the coast of Georgia, the other off the northeastern coast of 

 the United States, about the latitude of New York. D'Orbigny 

 originally described this species from shore sands of Cuba.
