Taking the average length of spicules of different colonies we find that those of 
the specimens from Spitzbergen have the greatest length. The statements of KÖKEN- 
THAL (1907) give the following lengths of spicules: upper part of anthocodia 0.30—0.40 
mm., lower part of anthocodia 0.12—0.14 mm., trunk bark 0.09—0.12 mm.
