The zooecia are all turned forward and arranged in longitudinal rows; they are 
hexagonal, limited by a suture in relief; the orifice is semicircular, deprived of spines; 
the ovicell is formed by the raising of the wall of two zooecia superior to that which 
bears it; it is divided into two halves by the sutural line of these zooecia; its opening, 
like a policeman's helmet, is entirely above and in front of the orifice. Dorsal face 
of the zoarium is divided into trapezoidal areas which are the dorsal faces of two 
zooecia. (After Jullien.)
