Catalog entries: Euscenium plectaniscus
Original description: Shell three-sided pyramidal, thorny, about as long as broad, with three dentate edges. Framework very loose, with irregular polygonal meshes; in the middle of each of the three triangular sides a horizontal band of denser network. Basal plate with three very large simple collar-holes. The apical horn and the three feet are three-sided pyramidal, about half as long as the columella, with three prominent irregularly dentate edges. The horn is straight, whilst the three feet are hook-shaped, its distal end being curved downwards and inwards.
Remarks on original description: Haeckel listed Euscenium plectaniscus under the subgeneric name Euscenarium, but did not include the subgeneric name in the species name.[comment from RadWorld database]
