TYPE SPECIES. — Eilhardia schulzei Poléjaeff, 1883 by monotypy.

The ostia-bearing surface is supported by a thin layer of tangential triactines and scattered microdiactines. The skeleton of the exhalant system and of the choanoskeleton is composed of large triactines and microdiactines. The cortical skeleton consists of giant longitudinal and small diactines as well as tangential triactines.
