The blisterlike branchiae on the dorsal edge of parapodia are char- 

 acteristic, as are also the short, blunt, bifid parapodial lobes, but both 

 of these features are less obvious on larger, presumably older individuals. 

 The numerous proboscidial organs nearly cover the proboscis. They 

 are elongate, somewhat compressed and distally slightly curved (fig. 8). 

 The oral side is ridged, crossed by 7 to 9 lines that meet in the middle 

 or are somewhat alternate (fig. 7); a midrib is usually visible. The 

 aperture is subdistal and sometimes wide open to considerably con- 

 stricted. The large basal cell (or cells) is clear and has a dark, spherical 

 mass, possibly nucleus. Individual organs are 76 micra in length, or 

 shorter. Their number on the proboscis of a larger individual is estimated 

 to be 60,000 to 75,000. 



The single, incomplete individual from Anaheim Slough, California, 

 reported as G. longissima (Hartman, 1940, p. 245) should be referred 

 to this species.
