Description Test biserially coiled. Initially, the first three chambers might be multiserial and constitute a juvenarium followed by a rapidly expanding stage of one or two whorls. Because of the complex type of coiling, chamber shape is very variable in sections.Sutures indistinct or faint. No supplementary deposits. Oral valvula absent or faint. Wall thin, unilayered, microgranular in the juvenarium. In the adult whorls, the wall is differentiated with a tectum and an inner coarse layer with calcareous agglutinated particles, fine to medium-sized. Aperture on last chamber, basal, simple).
Occurrence. Tournaisian–Serpukhovian; palaeogeographical distribution poorly known, but the family is possibly cosmopolitan.
