Chrysogorgia arborescens Nutting, 1908  

From Nutting, 1908:

Chrysogorgia arborescens, new species

Plate XLV, Figs 4  and 8 ; plate XLIX, Fig 6.Height of incomplete colony 162 mm. The main stem divides into two equal main branches about 25 mm from the bottom; branch origins two-fifths, right-handed. The distance between branch origins is about 8 mm, and the slightly ascending branches subdivide about four times. Normal polyps ordinarily one to each node, but two to a node on distal parts; rather slender, 1.5 to 2 mm high. Besides these there are a number of large abnormal polyps infested with parasitic crustacea. These polyps are in some cases as much as 12 mm high by 2 mm in diameter. 

Spicules, usually bar-like, arranged longitudinally on body wall and in tentacles. Not seldom irregular, branched forms are seen. The spicules in the modified polyps are larger than elsewhere, and tend to be more irregular. Here also they are arranged longitudinally in the body walls. 

Color of main stem light drab, main branches light yellow, polyps almost white. It is probable that the branches and polyps are bright yellow in life. The stem has a dull greenish iridescence, where denuded, and this becomes lighter green when the axis of the branches is seen.

Type.-Cat. No. 25354 U.S.N.M., Albatross. Station 3973, near French Frigate Shoal, 395-397 fathoms [722-726 m note EP]. Additional locality.-Between Hawaii and Maui: Station 4065, 491-500 fathoms [897-914 m note EP].
