Description
Test ovate, globular proloculus followed by enrolled, nonseptate tubular second chamber, which coils in quinqueloculine manner, wall calcareous, imperforate with growth lines on surface but no internal subdivisions, aperture simple, terminal, may have thickened rim. [Commonly placed in the Miliolidae because of its quinqueloculine appearance, Agathammina has been shown to be nonseptate and is here transferred to the Cyclogyrinae. Agglutinated species placed herein by various authors should be reallocated, in the Ammodiscidae.]
