Note
Pleioplana inquieta Heath & McGregor, 1912 , considered synonymous with P. californica by Hyman (1953).According to Hyman, P. inquieta not only shows the same morphological features as P.californica , but also shares the same habitat and distribution, namely Monterey Bay, California. Therefore, in this review, P. inquieta is considered a synonym of P. californica .
