This common species is represented by numerous specimens, of very varied form and 
colour. All agree in anthocodial armature, having a crown of 8—10 rows of spicules, and points 
with 2 pairs of principal spicules, en chevron, and sometimes smaller ones between them. 
The differences can best be summarised in a table.
