calyx, including spines, 3.5 mm; diameter at base, 1.9 mm; diameter 

 between tips of spines, 2.3 mm. The inner sides of the calyces are cut 

 away to the level of their bases, the polyp issuing ventrally between 

 the enormous spines and facing directly upward as if issuing from 

 the upper side of the calyx at its base. The calyx walls are filled 

 with long orange-brown needles arranged vertically and parallel. 

 Distance between calyx bases, 2.3 mm. There is a swelling beneath 

 each calyx base. 



There are no spicules in the polyps. The tentacles have large 

 pinnules. 



Zooids: There are usually two zooids just above and inside of the 

 base of each calyx on the dorsal? side, although there is often but 

 one; and one in a similar position on the ventral? side. There are 

 no grooves on the rachis, and the dorsal and ventral sides differ only 

 in the fact that the calyces are slightly inclined toward what I con- 

 sider, with some doubt, as the dorsal side. There is no fence of 

 spicules around the zooids. 



Spicules: These are all needle-like forms, slender, smooth and 

 sharp, averaging about 1 mm. long. 



Color: Golden brown, the rachis lighter and the calyces darker. 

 Polyps colorless.

A remarkable species, differing from all other pennatulids in habit 

 of growth. 



Order GORGONACEA. 



Fixed colonial forms with an axis cylinder composed of calcareous 

 or chitinous material.

Axis consisting of amorphous horny or calcareous material, or 

 both, and not penetrated by longitudinal canals; except, in some 

 cases, a central one. 



Family CHRYSOGORGIDiE VerrHl.
