NO. 1 HARTMAN : POLYCHAETOUS ANNELIDS 21 



Collections.— Acq. 590, D-104, 895-38, 897-38, San Pedro, Cali- 

 fornia. 5 specimens. 



Aphrodita ar/nifera is characterized by its heavy, smooth, dorsal 

 notopodial spines which are deep copper colored. These are conspicu- 

 ously heavier than the neuropodial spines and appear darker because of 

 their thicker stems. They are stoutest at the base and taper rapidly to 

 a blunt point. The longest are dorsalmost. They form 5 or 6 irregular 

 transverse rows on a parapodium. They project out from the body so 

 as to form a formidable series. 



The ventralmost neuropodial setae have a pair of spurs differing 

 from those in J. falcifera (cf. pi. 1, figs. 6 and 14). Median and su- 

 perior neuropodial setae do not have lateral processes. The presence or 

 absence of pilosity is variable. The ventral setae are ranked about as 

 follows: 2 superior, 3 median, 4 to 6 inferior. 



J. ar?nifcra differs from A. falcifera (see p. 23) most notably in 

 having copper-colored, nearly straight, stout dorsal spines instead of 

 yellow, slenderer, dorsal spines, and in having only the ventralmost 

 neuropodial setae spurred instead of all or most of them. 



A. armifera Fauvel (1925, pp. 144-147) from Australia is not the 

 same as A. armifera Moore. In the former, the notopodial setae are 

 rough, and the neuropodial setae have a lateral spur as described for 

 A. falcifera (p. 23). Fauvel designated the notopodial setae as "bronzees 

 ou dorees." In A. armifera Moore they are coppery. 



A. raripillata Essenberg (1917, p. 413) from southern California 

 may be referable to A. armifera Moore, although it is not certain that 

 the inferior neuropodial setae have the paired spurs characteristic of the 

 latter. In other respects the descriptions are similar. 



Distribution. — Southern California. Subintertidal to 55 fms.
