Description:

The identity of this organism is unconfirmed. This image is focussed just below the ventral surface. There seem to be 2 rows of marginal cirri - a distinguished feature for Holosticha, and there is a collection of transverse cirri at the back. The inner region of the Adoral Zone of Membranelles that arcs around the front of the cell is quite evident - but is larger than is usual for the genus Holosticha. The relationships between Holosticha and close relatives are subject to debate. Nomarski optics.
