Araeosoma coriaceum A. Agassiz

Family: Echinothuriidae

Order: Echinothurioida

Locality: Philippines, Camotes Island, 150 m, by tangle nets, 2.9.2009

Dimensions: 150 mm Ø

For comparing: Plate XXXIV, Mortensen, Mongraph of the Echinoidea, II

 I got the specimen without taxon, but there is really a great coincidence with Mortensen´s table.
