Skeleton consists of very typical Axinellioid-Rbres, constantly 
branching in very acute angles; the fibres are lying very close to 
one another, so that the spicules, which are placed with the apices 
directed obliquely oulwards in the fibres intercross the spicules from

neighbouring fibres; the fibres are rather strong, built up by several 
spicules in the row. 
Spicules: (fig. 29a—c) 1. styli, stout, curved; the bending 
may take place in various parts of the spicules; sometimes sub- 
tylostyli may be found; thickness most often the greatest just be- 
yond the bending; from here evenly tapering; length very varying, 
from 416—858 p. Lengths about 650 (i most common, by a 
thickness of about 20 fi. 2. rhaphides, of three sizes; a, hair-
