Test plano-convex, usually attached to various objects by the 

 flattened dorsal side, trochoid ; wall calcareous, coarsely perfor- 

 ate; aperture peripheral, at the base of the chamber, sometimes 

 extending ventrally, but typically with a long slit-like extension 

 between the inner margin of the chamber on the dorsal side 

 and the previous whorl nearly or fully the length of the chamber.

Test attached, in the early stages similar to Cibicides, the
