Diagnosis
ReferenceDiagnosis
J. A. Cushman 1926Test free, composed of a series of chambers in a coil, each chamber making a half coil of 180° and embracing so that but a small part of the base of the preceding chamber is visible from the exterior.; wall smooth, finely perforate, either thin and transparent or thick and opaque; aperture at the inner margin of the ventral face of the chamber, in a semicircle, narrow, often with
a slightly upturned lip.
In this genus the aperture is a very narrow, curved slit, at the base of the chamber at the inner margin. In young specimens there is a slight tendency to have a broader aperture corresponding roughly with that in the following genus which is its main characteristic.
