Little known of the living animal. Colour and shape briefly described by the Marcus's (1976) as 'living slugs are diaphanous with an opaque white diffuse network on the notum .... The branchiae are white, the velar processes and those of the rhinophoral sheath are peppered with white. The pinkish or dark intestine shines through the notum. There are 4 long tentacular velar processes, and although not described, a median dorsal white line down the posterior foot is visible in the drawings. Preserved animals ranged from 4-5 to 11 mm.
