The surface is finely conulose. The apical oscule has an iris-type diaphragm and is 5 mmin diameter. Color in alcohol is dark pink. Consistency compressible.  Skeleton.( Fig. 5b) A three-dimensional reticulation of rounded or elongately polygonal meshes made by amber colored fibers, of 70–130 µm diameter. The fibers have a vaguely striated bark and a pith occupying about 1/ 3 of the fiber thickness.   Distribution and ecology. GuyanaShelf (if correctly identied), Eastern Brazil, from 2–76 mdepth (previously down to 12 m).   Remarks.The descriptions by Pinheiro & Hajdu (2001)and Pinheiro et al.(2007)match the present specimen closely, but the depth from where it was obtained and the distance from the typelocality throw some doubt on the identification. 1424726403 1970-08-26 RMNH Guyana 76 6.7333 Material 551 -52.75 13 14 1
