 Test strongly plano-convex, dorsal attached side flattened or slightly 

 concave, ventral side very convex, periphery acute, keeled; chambers 

 numerous, 7 to 9 or more in the last-formed whorl, all chambers, 

 visible from the dorsal side, those of the last-formed whorl only 

 visible from the ventral side ; sutures slightly depressed on the ventral 

 side, on the dorsal side usually flush and somewhat limbate; wall 

 fairl}^ smooth, finely perforate; aperture narrow at the periphery and 

 extending onto the dorsal side along the inner margin of the chamber. 

 Diameter up to 1.5 mm.; height up to 1 mm. 



This species is recorded from many regions and also as a fossil,, 

 particularly in the Tertiary. In the Challenger Report, Brady records 

 it from numerous Atlantic stations, especially in cool water, but there 

 are numerous records for it elsewhere as will be noted by the abova 

 references which probably do not all refer to the same thing.
