The head is usually restricted to the mouth and large, white oral veil tinted faintly orange by the rest of the orange head and mouthparts within.
The asymmetric orange-brown digestive gland which extends forwards on the left of the animal, can be seen clearly through the sole. The posterior of the foot is smoothly rounded without a taper. The anterior is unevenly flattened with a central indentation around the mouth. The ample mantle extends well beyond foot and head, revealing its shining spicules.
