Diagnosis. Length 10–60mm, body barrel-shaped. Color in life orange-brown with some darker mottling. Five prominent oral valves conceal mouth. Feet uniformly scattered over body surface, capable of complete retraction. Bodywall thick, filled with ossicles consisting of deep cups (40–60 μm in diameter) and buttons (55–100 μm long); no plates.

Distribution. NC to E and W FL, Gulf of Mexico.

Habitat. Crushed shell sediments. 6– 124 m.

Remarks. Deichmann (1954) referred this species to her new genus Euthyonacta . Miller & Pawson (1984) found just two specimens in the “Hourglass” collection. Apparently this species is not common where it occurs.
