In T. cristallina, for example, the proboscis, when protruded, is three times the length of the body. Other modifications of the gut are discovered in the absence of a radula, and in the presence of a muscular bulb at the end of the proboscis for sucking in the body fluids of the starfish to which the gastropod is Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Nicol, J.
