Barrel-shaped, about 5 cm long. Color light tan to whitish, often with a pinkish tinge. Tentacles bushy, of equal size. Ventral feet ventrally in 3 distinct rows; toward oral and anal ends as few, scattered, broad and low papillae, with dark brown tips. Five dark brown anal papillae and 5 small calcareous anal teeth. Integument thick, fleshy, soft, almost devoid of ossicles, which are irregular 4 -holed buttons (100 μm) with low knobs. Distribution. NC to SC, Gulf of Mexico. Habitat. Sand/mud. 18– 215 m. Remarks. Little is known about the biology of this species, although it is obviously a suspension feeder, and presumably, given the nature of the substrate, a burrowing form.
