The singularly soft and flexible slender branches of this species 

 readily distinguish it. They rise from a stout pedicel, an inch or 

 more thick, and are crowded, and but little subdivided. Quoy and 

 Gaymard, obtained their specimens " a d'assez grandes profondeurs," 

 while those from the Feejees occurred near the surface. The polyps 

 are represented by them as having a yellowish disk. In the Feejee 

 specimens, the colour was pale yellowish flesh-colour, and the tenta- 

 cles were bright yellowish-green, with the basal portion brown.
