The most seen in a single group is 13 (USNM 84869D, Foerste, 1909. pi. 10, fig. 4e). Most of these clusters apparently represent pseudo- colonies. Often the tips are separate and the coralla expand upward into lateral contact. Less commonly, the tips are in contact or the tip of one coral is attached to the side of another, but separating walls are present. In only two specimens has lateral and peripheral in- creas
