of which, the one part is somewhat thicker than the other. The 

 basal part is 70 mm in circumference; and from it, a couple of 

 extremely short, thin, branches shoot out, on whose extremities 

 there are 3 — 4 polyps. From the 2 stems many, larger and smaller, 

 branches proceed, which become several times ramified; the out- 

 ermost branchlets carry 3 — 6 polyps on their extremities, and, of 

 these, sometimes 2, and sometimes 3, are concreted together at the 

 base. The stems, and the branches with their ramifications, are n on- 

 calcareous; only the basal part posesses spicules, of which, the 

 bi-stellate is the most frequent form. The polyps are rather short, 

 and are furnished with spicular series which, on the dorsal side, 

 occupy the entire length of the body, but on the ventral side oc- 

 cupy, only, the uppermost half-part of it. The spicules have, 

 principally, the form of spicate fusees, sub-clavates, twins, and 

 quadruplets. Colour; the stem, and the branches, violet, shading 

 a little towards yellow. The polyps intense violet.

Specific characteristics. 



The Zoanthodem measures up to 35 ram in height. The 

 stem, cylindrical, longitudinally furrowed; 20 — 25 mm in circum- 

 forence at the base, diminishing, a little, in thickness, upwards. 

 The basal part thin, and membranaceously dilated. The stem, 

 right from the base up to its summit, beset with short, thick 

 branches which, as a rule, ramify, a few millimetres beyond their 

 root, into 3 — 4 smaller branches; these again ramify into many 

 branchlets each of which carries 6 — 7 polyps. The latter are 

 claviform, and measure 4 mm in length. The body of the polyps 

 measures 2,5 mm in length, and is richly furnished with spicules 

 which, upon the anterior body, arrange themselves in series that 

 terminate at the root of the tentacles. The tentacles are, almost, 

 as long as the body, and are devoid of spicules. The spicules, in 

 the basal part and the lowest part of the stem, appear, principally, 

 in the form of spicate, warty, bent or straight, fusees, also as very 

 complex stellates. Between them, occasional bi-stellates, sub-clavates,
