V. J. Okulitch 1950cups of cylindrical or conical shape, the outer wall transversely annulated by deep horizontal bulges. Parieties in part well defined and radial, in part wavy, passing into trabecular tissue within the bulges. All parieties more or less synapticulate. Dissepiments are present in some of the species. Inner wall simple, perforated by the usual pores or larger canals.
