Consistence ra.her firm, papillae brittle. Colour lig.h f'^sh-coloured, 
papillae evenly discoloured towards apex, on account of the de-

diverging. In the innermost part of the sponge-body these fibres 
are lying so closely together, that the obliquely 
spicules from two neighbouring fibres are crossmg one another 
in thi« way the skeleton is woven into a compact totahty; between 
and in the fibres are sca.tered small styli, apparen.ly without part¬ 
icipation in the building up of the skeleton; the small styli may 
be lying with the apices in every direction. In the free papillae 
the spicula-fibres are also lying densely together; in continuation 
of the obliquely placed spicules in these fibres are lymg ot er 
spicules, whose direction is more and more transversal; they may 
assume the character of very much diverging skeleton-fibres.
