Genus Leucyssa Haeckel, 1872 View in CoL
TYPE SPECIES. — Leucyssa spongilla Haeckel, 1872 by monotypy.
DIAGNOSIS. — Trichogypsiidae (?) with a skeleton composed only of smooth diactines.
DESCRIPTION
The external shape of this sponge, which has a pedunculate cormus with a large clathrate body of anastomosed tubes, is quite different from both the Baeriida and Leucosoleniida , and is rather common among the Clathrinida . However, Eilhardia also has quite an unusual shape, and it is possible that our knowledge of only a very small number of sponges in the Baeriida gives the impression of a great divergence of the observed forms. We place this sponge among the Baeriida , following Haeckel’s (1872) description of the rather irregular alveolar choanosome supported by a dense skeleton of small diactines, scattered without order.
