Original Description
Radial proportion of the three shells 1: 2,5: 9. Cortical shell thick-walled, with circular, regular, six-lobed pores, as broad as the bars. At each nodal-point is a bristle-like spine, half as long as the radius, thus every pore surrounded by a corona of six bristles.

Diameter of the outer shell 90µm, of the cellules 1µm. Distinguishing characters (rw): Owing to the thickness of the cortical shell, the interior shells were visible merely as faint shadows, so I am not quite convinced whether the shells are 3 or 2. If the latter be the case, the species belongs to Haliomma and is then nearest akin to H. horrida.

Editors' Notes
For H. horrida read H. horridum.
