DIAGNOSIS. — Leucosoleniida with a syconoid, sylleibid or leuconoid organisation. The thin wall surrounding the large atrial cavity is supported by tangential atrial and cortical skeletons, and an inarticulate choanoskeleton consisting of unpaired actines of the subatrial triactines and/or tetractines, and occasionally with small radial diactines. The proximal part of the large radial diactines that protrude from the external surface, or the tangential triactines scattered irregularly in the cortex, may also form the choanoderm. Large cortical tetractines or subcortical pseudosagittal triactines are not present.
DESCRIPTION
In the revision of Calcaronea also published in the present volume, Borojevic et al. propose to separate a group of sponges characterized by an inarticulate choanoskeleton in the family Jenkinidae (Borojevic et al. 2000) . The new genus Leucascandra is a typical member of this family.
