"A species of Cyclonephelium whose outline is
roughly circular. It has a low, distally rounded and closed apical horn and
a left antapical prominence may be present. A dense, low ornament covers the
ventral periphery and takes the form of irregular granules or short coni which
may coalesce laterally to produce a crude microreticulum. Some interruption
of ornament may be observed laterally in a position corresponding to the paracingulum.
The archeopyle is apical with the operculum usually completely detached. Paratabulation
is lacking, but parasutural splits around the archeopyle margin indicate the
presence of six precingular paraplates. The parasulcus is offset to the left."
