Diagnosis. 
Zoarium irregularly branched. The branches are at first 
narrow and expand distally. The branches subdivide once 
or twice, and remain distinct. The zoarium is thick, 
especially at the distal ends of the branches. 
Zooecia long, cylindiical, and fairly stout. They are well 
raised distally. The apertures are irregular in distribution 
and widely spaced. 
Gonocysts long, and irregular.
