Diagnosis. Zoarium massive; either spherical or of irregular 

 lobed masses, generally with a broad base, protected by epitheca. 

 The surface is level and ornamented with irregularly scattered 

 tubercles. [These are only seen in well-preserved specimens, as 

 in PI. XI. Pig. 5 ; they may be acanthopores.] Diaphragms 

 abundant. Young zooacia are fairly abundant, and being smaller 

 in size resemble mesopores.
