Skeleton:
Authors state it was difficult to determine due to damage. Multispicular tracts of long diactins incorporated within plumose skeleton of monactins.
Distribution: Southern California, Santa Maria Basin.
Depth: Deep water, 92-100 m.
Note: Originally described from tiny, damaged fragments which included the very large Oxeas listed above. These may be a contaminant. Note also that in the same publication the authors described Hymedesmia (Holerodesmia) sp. A which has now been synonymized with Clathria (Microciona) sp. A. As a result, both of these are represented as sp. A. To avoid confusion we have designated these two species as sp. A-1 and species A-2. See page 156A.
