). The diameter of ovicell spine bases is markedly smaller than that of mural spine bases, especially the nearby oral spine bases of the maternal zooid. In all cases observed, the distal, median ovicell spine bases are located on the mural rim of the distal zooid where mural spines were absent. The two most proximal spine bases are placed very close to the distal edge of the maternal zooid. Ovicell spine bases are closely spaced, with the distance between adjacent bases usually less than spine base diameter, except in the distal part of the ovicell where the spine bases are sparser and spaced further apart.
