The object in the background is a penny, c: Characteristic scar created by peripheral basis-attachment processes. Cyamid induced excavation of the skin and subsequent pigment transformation are evident in this plate. The cyamids are C. scammoni. d: Wound left by the ablated barnacle. Cyamid-induced abrasion has almost com- pletely healed with the replacement of the coreum, but pigment transformation from gray-black to white continues, e: Pigment transformation is almost complete, f: Complete pigment transformation has produced the characteristic round to oval barnacle scar seen on gray 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 Southern California Academy of Sciences.
