Description
Genus Leucyssa Haeckel, 1872
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.
