If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
|D. C. García-Bellido et al. 2007||Elongate or goblet-shaped, tubular to obconical, very thin-walled sponges with double-layered skeleton. Coarse, moderately widely spaced, en echelon oxeas are dominant elements that extend as parallel rods virtually the entire length of the sponge in the outer skeletal layer. Spaces between rods filled with thatch of smaller
vertical oxeas that combine with coarse rods to produce the outer skeletal layer. Inner layer a thatch of tiny horizontal, monaxial spicules. Vertical small spicules do not occur in bundles, while horizontal spicules are not clustered or cluster into ill-defined bundles. Walls lack parietal gaps and major canals.
