The spined acuate spicules (Plate 25, fig. 40) are totally spined, 
the spines being comparatively few in number. They are 
thickest at the base, sometimes subspinulate, generally curved. 
'The length is 0,;—0,55 mm. 
The obtuse spicules (Plate 25, fig. 41). "These spicules are 
very few, totally smooth and usually a little inflated at the 
terminations. The length is 0,4 mm. 
The bihamate sprwcules (Plate 25, fig. 43, 44) are comparatively 
large, C- and S-formed, the straight length between the points 
being 0,1—0,15 mm. 
The amchorate spicules (Plate 25, fig. 42) are abundant in the 
inner membranes as well as in the dermal membrane. Their 
length is 0,035 mm. 
The forcepiform spicules (Plate 25, fig. 45, 46). These spicules 
are. very characteristic for the species. One of the. branches 
158 shorter than the other, the proportion being 1:2. They are 
inflated at the ends and wholly microspined. The length of 
the greater branche, which is curved, is 0,05 mm.
