The test, or shell, may be trochospiral to planispiral throughout, or just in the early part with the later part uncoiled. Chambers may be somewhat enveloping, and attached forms may uncoil in the adult. In coiled forms, the aperture is interiomarginal, or terminal in uncoiled forms. The test wall is of perforate hyaline (glassy) oblique calcite, appearing optically granular.
