Notes

Appears rare throughout range. Many known occurrences extirpated; need information. Most Channel Islands contain only a few occurrences each. Need quads for SCM and SRO islands. Greatly reduced by urbanization on mainland. See Proceedings of the Biological Society of Washington 17:99 (1904) for original description.
