Char. — Zoarium large (100 mm. across), of stout, short, digitate branches, which 
may expand distally. The branches, which are about 12 mm. in diameter, may 
anastomose. The sides of the branches are marked by annular lines. Apertures 
small, square, or round ; widely scattered, and between them are two series of 
mesopores, which are half the diameter of the zooecial apertures.

annulation and distal expansion of its branches.
