Diagnosis: Cell enclosed within a membranous sac which is fixed to the shell at intervals, but lost in empty shells. This membrane closes the shell from the ventral side and forms an aperture for the lobopodia.

Genus Spumochlamys
Diagnosis: Cell not enclosed within a membrane, but the ventral side is closed by a membrane, which forms an aperture for the lobopodia.

Genus Pyxidicula
Diagnosis: Test with alveolar structure and wide pseudostome.
