Material. 131 specimens from 24 samples.

Description. Test small, subspheric, circular in outline or flattened, composed of a long tube-like chamber streptospirally enrolled around the proloculus (never visible) about up to three different axes of coiling. Wall finely agglutinated, surface smooth.

Distribution. Cosmopolitan taxon known from the Jurassic to Recent ( Kaminski and Gradstein, 2005).

Remarks. The outern morphology of R. charoides is widely variable, Berggren and Kaminski (1990) recognize a dozen of synonim subdivided into four groups.
