(Selenka, 1867)

H. (Microthele) nobilis is a black sea cucumber, often with a fine sand covering. It is a large, stout species, firm and rigid, with prominent lateral papillae and anal papillae (usually 5). It has translucent cuvierian tubules. Spicules are stout tables and fenestrated ellipsoids (H. nobilis spicules, H. nobilis spicules 2). H. nobilis may be found on reefs, and exposed on rubble or sea-grasses.

Remarks: A variegated black and white variant of 'nobilis' is known in Queensland. This may prove to be H. (Microthele) fuscogliva a recently described species (Cherbonnier, 1980).
