Description

Test shape elongate, cylindrical, commonly distinctly curved, sometimes nearly straight, slightly nodular in latest chambers, somewhat tapering into a pointed end. Length of test 3–5 mm, the largest specimens nearly 7 mm; test width usually 0.6–0.8 mm. Chambers subglobular, rectilinearly arranged; number of chambers 8–11 or up to 13. Initial 6–9 chambers in microsphere are arranged in an evolute planispiral, nearly completing one whorl ( Fig. 6C ). Sutures horizontal, sometimes slightly oblique. Aperture radial, eccentric, protruding, made of up to 12 rather broad symmetrically arranged tines, that are fused in the center. Initial end with a short spine. Conspicuous longitudinal costae run the whole length of the test along slightly twisted lines; the costae divide or fuse as the diameter of the test changes; the apertural face is free of costae ( Fig. 6A, D ) and in occasional specimens the last one or two chambers are smooth. Secondary surface laminations seem to cover whole test (ortho-lamellar). Wall thick and finely perforated, except for nearly imperforate narrow segment close to the aperture.

Remarks

Seven microspheres were found among the 1082 examined specimens. Diameter of the proloculus in microspheres is about 0.02 mm, and> 0.2 mm in the megalospheres. Secondary laminations of successive chambers levels out the slightly nodular character of the earlier part of the test, resulting in an evenly tapering cylindrical shape.
