Atolla wyvillei

Remarks. All three WAM specimens were retrieved from a midwater trawl, and are in poor condition. The only identifiable characters are the well-preserved coronal band and the protruding radial muscles. The other specimens are in slightly better shape, with the characteristic clover-shaped stomach and radial muscles plainly visible. Despite their relatively poor condition, the specimens match primary descriptions of A. wyvillei (Haeckel 1880; Mayer 1910; Kramp 1961; Larson 1986 b).
