NO. 3 HARTMAN : POLYCHAETOUS ANNELIDS 207 



purple. Ventral cirri pale. Branchiae pinnate, present from the fourth 

 setigerous segment, to the posterior end. 



Notopodia provided with bifurcated setae, some of which have mi- 

 nute serrations on the inner side of the main fang, the serrations directed 

 distally (pi. 31, figs. 12, 13). These are, thus, in sharp contrast with the 

 condition in C. entypa (see above). Anal cirri are elongate, cylindrical, 

 directed posteriorly (pi. 31, fig. 11). 



These specimens have been identified with C. pinnata Moore because 

 of the presence of the unique, serrated notopodial setae. In this character 

 it differs distinctly from the other two species, C. viridis and C. entypa, 

 reported from the eastern Pacific (see above). 



Distribution. — Southern California. Subintertidal, to 310 fms.
