in length, consisting of symmetrically oval proloculus followed by 1–6 approximately droplet-shaped to subcylindrical chambers separated by distinct, regular constrictions or short stolons. Chambers arranged in linear sequence along straight, gently arcuate or occasionally slightly sinuous axis. Proximal end (base) of initial chamber (proloculus) either smoothly rounded or interrupted by pocket-like invagination. Test wall rigid, fairly brittle, orange or yellowish-brown in colour and more or less transparent. Wall mainly organic but incorporating some fine, adhering particles, in some species concentrated in constrictions between segments. Some or all chambers contain stercomata. (Slightly modified after

with test comprising gently curved series of 3–4 (occasionally five) elongate, droplet-shaped to subcylindrical chambers, separated by distinct constrictions. Initial chamber (proloculus) with smoothly rounded proximal end lacking basal invagination. Final chamber somewhat asymmetrical with round terminal aperture. Test wall transparent, pale yellowish in colour, mainly organic but incorporating some clay particles. Surface of proloculus smooth at submicrometre scale. Surfaces of later chambers covered in mass of short, branching, finger-like projections up to 0.1 Mm long, visible only by SEM.

with test comprising two oval to droplet-shaped chambers arranged on a linear axis and separated by short neck. Initial chamber (proloculus) with rounded or somewhat pointed proximal end which lacks basal invagination. Test wall basically organic and transparent; second chamber distinctly brownish-yellow in colour. Surface of proloculus smooth at submicrometre scale, sometimes with partial veneer of plate-like clay particles. Second chamber with variable number of small, irregularly arranged mineral grains concentrated in proximal part; other parts of wall with flat, scale-like features (probably clay particles) merging into meshwork of bar-like elements, visible only by SEM.

). The initial chamber is more or less symmetrically oval, often with a somewhat pointed proximal end. The second chamber is droplet-shaped, widest behind the mid point, and tapers towards the slightly truncated apertural end. The initial chamber is joined to the second chamber by a very short, narrow neck. The overall length of the test is 107–190 Mm (usually 164–190 Mm; mean 167 Mm, SE 25.0 Mm). The first chamber measures 50–85 Mm (mean 65 Mm, SE 11.7 Mm) long and 28–53 Mm (mean 43 Mm, SE 6.6 Mm) wide. The second chamber measures 70–133 Mm (usually 106–133 Mm; mean 112 Mm, SE 18.2 Mm) long and 38–93 Mm (usually 54–93 Mm; mean 67 Mm, SE 18 Mm) wide.

One specimen examined by SEM has a circular opening, ~15 Mm diameter, enclosing a rather complex organic structure (

The test wall is basically organic, transparent, with a distinct, brownishyellow colour in transmitted light. The colour is usually more evident in the second chamber, which has a thicker wall than the first chamber. A deposit of finely agglutinated material, visible by light microscopy, is often loosely attached to part of the wall of the second chamber (
