Yes I did. I have personally been on Isla Coronado and I saw two caliginis there. They are a small version of helleri, down to the wide dark band at proximal to the tail. This is typical island dwarfism. Murphy is probably correct about the two populations never meeting again but as of yet, they are not different species. Using Murphy's train of thought, I might as well describe the Catalina Island helleri as a unique species.
