Microhedyle lactea

(Hertling, 1930)

This shell-less species may reach 2 mm in extended length. The body colour is white. Stellate calcareous spicules are present in the mantle. Eyes are present. The oral tentacles are cylindrical, not markedly flattened.

This species, living in shelly gravel, has been recorded from Plymouth Sound, from a locality off the Lizard, Cornwall, and from the Yorkshire coast. Elsewhere it occurs commonly in the Mediterranean Sea and on the Atlantic coasts of France, Germany and Sweden (Distr. M. lactea).
