series, and a somewhat shorter anterior body, where the spicules 

 form 8 longitudinal series. The tentacles are half the length of 

 the body. The entire Zoanthodem is furnished with spicules which 

 appear, throughout, in the form of bi-stellates. On the anterior 

 body of the polyps alone, does the fusi-form appear. The gullet 

 has, on each side, a broad longitudinal series of spicules. The 

 ventral and dorsal sides are devoid of spicules. Colour; reddish 

 yellow. The polyps faint rose-red colour.

Specific characteristics. 



The Zoanthodem bushy, measures up to 40 mm in height. 

 The basal part membranaceously dilated. The stem cylindrical, 

 encompassed by closely-set branches, right from the base up to 

 the summit. The branches richly beset with branehlets carrying 

 a, larger or smaller, multitude of polyps which group themselves 

 so closely round the branchlet that not only do they conceal it, 

 but, also, the branch, which, consequently, appears to consist of a 

 single polyp-group. The polyps measure 8 mm in length, elongate 

 chalice-formed, with prominent posterior body, furnished with 

 8 spicular ribs continued into the tentacles. Between these, at 

 their base, a bare triangular space beset with nematocysts. The 

 pinnules noncalcareous. In the basal part, foliaceous clavates and 

 complex stellates are the most frequent spicular forms, more rarely 

 quadruplets. In the stem, bi-stellates appear, and these, as well 

 as complex stellates and clavates are the most frequent forms. 

 In the branches, the bi-stellate is the most frequent form. In 

 the polyps, large, foliaceous clavates are the most frequent spicular 

 forms. Colour; rose-red.
