Yes this is the photo that is in Dave Behren's book. He reported it from the San Francisco region, California in 1971. There is a difference between the natural distribution, or geographic range of a species, and records which appear to be the result of human activity. I suspect its presence in San Francisco is the result of human activity. So as not to confuse 'natural' and 'unnatural' distributions, I think it is probably best to use 'distribution' only when we are talking about a natural distribution. However there is no way to standardise such usage of words so we just have to be aware that these days, species can turn up in strange places.
Reference: Behrens, D.W. (1971) Eubranchus misakiensis Baba, 1960 (Nudibranchia: Eolidacea)) in San Francisco Bay. The Veliger, 20(1): 214-215.
Best wishes,
Bill Rudman
