COMPLETE HARTMAN: POLYCHAETES FROM CALIFORNIA 125 



2. Prostomium followed by a smooth peristomium, and this by 3 

 or 4 segments with pointed setae, and 6 or 5 segments with 

 long handled hooks Capitomastus sp. 



2. Prostomium followed by a smooth peristomium and 6 setigers ; in 

 both male and female individuals the last 3 thoracic neuropodia 

 with hooks, and notopodia with hooks in the 7th, and genital 

 spines in the 8th and 9th segments . . Capitellides sp. 



3. Body larger, finely speckled with punctate dark spots ; prosto- 

 mium followed by 7 segments with pointed setae and 2 segments 

 with genital spines in notopodia . . Capitella, punctate 



3. Body smaller, epithelium not punctate 4 



4. External surface of body villose ; first 5 or 6 segments with 

 setae in notopodia and neuropodia, followed by one segment 

 with setae and hooks, and this with long handled hooks only 

 Capitella, villose 



4. External surface of body smooth ; in female individuals thorax 

 consisting of 6 setigerous and 3 uncinigerous notopodia, and 

 male individuals with 4 setigerous, 2 with setae and hooks mixed, 



and 3 with hooks (genital spines absent) 



Capitella fcapitata 



None of these individuals agrees fully with the typical Capitella 

 capitata (Fabricius), known from Greenland and boreal Atlantic seas, 

 which is characterized as follows : in the male, the prostomium is followed 

 by 6 setigerous notopodia and neuropodia, the seventh segment is variable 

 or mixed (with setae and hooks) and the eighth and ninth notopodia 

 have genital spines whereas the corresponding neuropodia have long 

 handled uncini. 



Capitella capitata (Fabricius) 1780 ovincola Hartman (1947, p. 405), 

 from southern California, has the following formula. The male: prosto- 

 mium followed by 4 setigerous notopodia and neuropodia, the next 3 

 segments are mixed, the eighth and ninth notopodia have genital spines 

 and neuropodia have hooks. In the female the formula is the same except 

 that the genital spines are replaced by long handled uncini. 



Capitellid, genus and species probably unknown 



Collections. Southern California, in shallow sandy bottoms, in 

 depths of 10 to 30 ft (many).
