Description
Test free , more or less flexible and varying in consistency from soft and flaccid to stiff but G somewhat elastic . Composed of one or more plate - like parts . Occurrence : One species has been recorded from 3 closely spaced localities in the H abyssal northeast Atlantic but the vast majority of records are from the Indian and Pacific Oceans, 981-6380 m.

Surface with distinct concentric zones, each 35 mm broad . Linellae L strongly developed , unbranched , 3-4 m thick, forming a distinct surface layer and often occuring in bundles .
