Sydney Harbour, New South Wales, Australia. Oct 1989, AM C160803. Photos: Bill Rudman [Further details to follow]

Small polycerid of unknown affinities, with radula apparently fused into a cone of rods. Nothing is known of its biology but it often associated with the bryozoan in the accompanying photos on which it is quite camouflaged, the small orange spots matching the darker apertures in the bryozoan colony.
