Original Description

This flabellate test is composed of planispirally coiled chambers in the initial stage, followed by a biserial stage. Later the biserially arranged chambers become divergent and a second biserial stage is interposed between the two original series. In the last stage more chambers may be interposed. The initial stage and early part of the first biserial stage, i. e., the first nine or ten chambers, are entire or un-lobated in lateral view, and the chamber walls are devoid of surface markings. The later part of the first biserial stage is composed of peripheral or outer chambers. They exhibit fine longitudinal striae. The outline of the test in the later stage is distinctly lobated. Strong lateral compression flattens the interposed chambers below the level of the outer chambers. In the early stage the chambers are not inflated. In later development they are inflated and tend to become reniform. The sutures are flush in early development; later they are impressed and limbated. The last chambers are damaged or missing in our specimens and the apertures could not be observed.
