B) basically constructed of thick tracts of oxeas, running towards the surface, there forming long surface processes. Tracts interconnected by secondary tracts, consisting of fewer spicules and less consistent throughout the sponge. Secondary fibres usually run in right angles to primary fibres. Epidermis formed by some unorganized oxeas and mainly chelae. Chelae also found free within the choanosome in high abundance. Tissue comprising a good deal of incorporated sand grains and some overgrown Bryozoans.

, as described by Brøndsted (1927), no additional smaller oxeas occurred. Still, in our opinion (as discussed above), this cannot be considered a real evidence for a taxonomic differentiation, as these spicules are rather few in our specimens and are very likely to be mere juvenile growth forms of the larger, common oxeas.
