Test large, 2 mm to 4 mm in length, uniserial and rectilinear, with closely appressed chambers; wall coarsely agglutinated, outer layer of tightly packed grains, inner layer less firmly cemented and friable, with carbonate cement; aperture terminal, an elongate oval slit, nearly flush with the surface and lacking a distinct neck.

Remarks: Although originally the type species was referred to Sulcophax, the present genus is large and has a thick, coarsely agglutinated wall, whereas Sulcophax is a small, delicate form with a single layer of grains in the wall and an aperture recessed in a termi­nal furrow.
