Originally described from the Mediterranean, it is found throughout the Indo-West Pacific and also the tropical west American coast and the Caribbean, under various names. In the Pacific it was usually known as Berthella pellucida. It grows to about 20mm and usually has a translucent white background with a network of white lines around low pustules. The brownish viscera is visible through the mantle wall and most specimens have traces of a white cross-like mark in the centre of the mantle with four white diagonal marks arranged symmetrically, one between each pair of the arms of the cross. The markings are usually more obvious in juvenile specimens. In adults, often only the four diagonal white marks are present. There is a flattened, thinly calcified, but well developed shell embedded in the mantle tissue.
