the test of "anchispirocyclina" is discoidal, thin and often slightly undulating. the early stage is close coiled, later flaring some becoming circular in outline. walls are microgranular to finely agglutinated. chambers have complex interiors produced by a network of rafters and beams. those near the median plane have an irregular labyrinthic structure produced by radial pillars or buttresses extending from septum to septum between adjacent apertural openings.
