Diagnosis. 
Fascigeridse with a zoarium of long branches, which may be 
simple or branch into a dendroid, stipitate zoarium. The 
capitulum is simple or lobed. The branches are cylindrical 
and may be clavate. 
The sides may be covered by a thick epizoarium, or marked by 
interzooecial strise or grooves. 
‘ In d’Orbigny’ s figure the apertures of the outermost ring appear as a circle 
of long, slit-like depressions, the shape of which is probably due to the upper 
surface having been worn down.
