narrow, and strongly grooved longitudinally ; its uppermost two-third 

 parts is, round about it, furnished with branches ; the lowest third 

 part has none but, in this situation, a few polyps spring direct 

 from the stem. The branches are somewhat dispersed and, usually, 

 ramous. Both, upon the branchlets and upon the non-ramous 

 branches, the polyps appear in groups. The stem, the branches, 

 and the branchlets are extremely rich in calcareous spicules. The 

 polyps are long and cylindrical; very rich in spicules; and are 

 furnished with 8 projecting ribs. On the anterior body, the spic- 

 ules are placed, almost erect, in 8 double series, and are formed, 

 principally, of spicate, partly, bent, partly, straight, fusees. On 

 the posterior body, the spicules are placed transversally, and have 

 the form of wart-shaped rollers, bi-stellates, quadruplets, and spicate 

 fusees. The tentacles, and the pinnules, are completely ensheathed 

 with spicules of various forms. The gullet furnished with 8 closely- 

 set double series of, principally, spicate fusees. Colour: yellow, 

 shading a little to brownish.

Specific characteristics. 



The Zoanthodem measures up to 110 mm in height, and has 

 a basal part which terminates, sometimes, in cylinder-form, some- 

 times, in discoid- form. The stem is cylindrical; longitudinally 

 grooved ; pretty hard, and furnished with branches which begin to 

 shoot out a short distance above the basal part. The branches 

 are placed pretty far apart from each other; thick, with truncated 

 extremities ; they are richly beset with polyps which, partly, group 

 themselves together and, in that manner, -form the branchlets. The 

 polyps are chalice-formed and measure 8 mm in length, of which the 

 tentacles compose about a third part. The stem, branches, and 

 polyps are rich in calcareous spicules. The spicules appear, upon 

 the basal part, the stem, the branches, and partly, upon the 

 posterior body of the polyps, principally, in the bi-stellate form, 

 and, on the anterior body, as fusees. The form of the species 

 varies pretty considerably, but the spicular arrangement and form
