Description. — Test plaiios])irjil. i^irlially involute, composed of 

 about three coils, biconcave, periplierv thick, squarely or obliquely 

 truncate, earlier coils somewhat exposed in the umbilical region; 

 chambers numerous, about nine in the final coil, broad and low, not 

 well defined from the exterior, sutures indistinct; wall fairly thick, 

 roughened, composed of coarse sand grains; aperture a narrow slit 

 at the base of the final chamber; color l)rown. 



Diameter, 0.56-0.75 mm. 



Distribution. — Brady gives several ChaUenger stations for this 

 species in various parts of the Atlantic at depths ranging from 1,000 

 to 3,150 fathoms (1,829 to 5,761 meters). Pearcey records it from 

 two Scolia stations in the South Atlantic in 1,946 and 2,110 fathoms 

 (3,559 and 3,859 meters). I have had single specimens referable to 

 this species, one from D2140, in 966 fathoms (1,767 meters) south of 

 Jamaica, the other, D2761, in 818 fathoms (1,483 meters) off Brazil.
