Description. — Test small, planospiral, composed of al)()tit three 

 coils, not completely involute, the chambers of earlier coils visible at 

 the center in the umbilical region which is also depressed, pcri])hery 

 slightly lobulated. chambers niunerous, 7-9 in the last-formed coil, 

 subglobidar, sutures distinct, slightly depressed, wall of fine sand 

 grains with an excess of yellowish or reddish brown cement, smooth 

 and ])olished: aperture a short narrow slit slightly above the base 

 of the chamber; color yellowish or reddish brown. 



Diameter, 0.5-1.25 mm. 



Distribution. — This s])ecies is very widely distributed in all the 

 ocean basins but is never abundant. More of the stations are in 

 cold water than elsewhere, although the specimens are more common 

 in material from off the southwest of Ireland than at any other station 

 from which I have seen material. 



The Challenger stations cover the Atlantic well. Goes records 

 it from the Caribbean. It occurs at several stations in cold water off 

 the northeastern I'nited States and at one station in the Gulf of 

 Mexico and two in the Caribbean. The Scotia had it from the South 

 Atlantic and Antarctic." The most northerly station is Davis Strait 

 from which the first known specimens were obtained. Egger records 

 it from two (razelle stations oif the west coast of Africa, but his figures 

 are diflicult to make sure of and it may or may not be this species.
