fimbriata), and Hartman (1936b, 1940) with six species (Boccardia 

 brachycephala, B. truncata, Polydora amarincola, Pygospio californica, 

 Rhynchospio arenincola, and Streblospio lutincola). The present report 

 brings the total to 23 species, with one other regarded as indeterminable 

 and another a possible synonym. 



The following lists 1 1 genera and 23 species recorded from California. 

 Ten of these, preceded by an asterisk, are newly reported; 2, Polydora 

 citrona and Spiophanes missionensis, are believed to be new to science.

Two other names in the literature merit consideration. Spio califor- 

 nica Fewkes (1889, pp. 37-38) is a Polydora or Boccardia, species in- 

 determinable (Hartman, 1936a, 1940), which renders the next name a 

 homonym. Polydora californica Treadwell (1914, pp. 203-204) from 

 unknown locality, though named for California, is perhaps what has since 

 been designated Boccardia proboscidea.
