Alveolinidae

Alveolinidae is a family of spheroidal to fusiform milioline foraminfera with multiple apertures and complex interiors in which chambers are subdivided into chamberlets and subfloors interconnected by passageways. As with all Miliolina, the test wall in alveolinids is porecelaneous and imperforate. In living individuals the pseudopodea emerge through the multiple apertures that line the apertural or leading face of the test.
