Family SYCETTIDAE Dendy, 1892
DIAGNOSIS. — Leucosoleniida with a central atrial tube and perpendicular regularly arranged radial tubes lined by a choanoderm. The distal cones of the radial tubes, which may be decorated with tufts of diactines, are clearly noticeable on the sponge surface. They are never covered by a cortex supported by tangential triactines and/or tetractines. The proximal skeleton of the radial tubes is composed of a row of subatrial triactines and/or tetractines with rows of tubar triactines and/or tetractines behind. Distal pseudosagittal spicules are absent. A tangential layer of triactines and/or tetractines supports the atrial wall.
