together than the posterior, and in front of the insertion of the median 

 antenna. The paired antennae are larger than the median one, which is 

 inserted at the frontal margin of the prostomium. The large oral aperture 

 is ventral, located at the middle of setigerous segments 3 to 5. A pair of 

 large, thick palpi taper distally to truncate ends ; they are directed for- 

 ward beyond the ends of the paired antennae. The palpi are best seen in 

 ventral view, as their bases are nearly in line with the paired first ventral 

 cirri. 



Parapodia 1 and 2 are fused and reduced; the first parapodium is 

 smallest, represented only by a pair of biarticulate cirri, on either side, 

 directed forward at the sides of the palpi, and by a weakly developed 

 notopodial fascicle of slender setae. The second segment is normal in that 

 dorsal and ventral cirri are accompanied by setigerous lobes and the 

 normal complement of setae ; this segment extends across the midventrum 

 but in front of the oral aperture. From the third segment the parapodia 

 are normal. 



The caruncle is a conspicuous depressed globular lobe behind the 

 prostomium, best seen when the paleae are pushed aside. It is less than 

 half the prostomial size and thus notably smaller than that of Paleanotus 

 bellls (below). Other details are given in Johnson (1897, p. 161). 



Chrysopetalum occidentale is recorded from southern California and 

 western Mexico, in intertidal depths, in rocky habitats.

Collections. This species has been taken intertidally, on piles, among 

 tunicate and seaweed colonies, from Mytilus colonies, and from encrust- 

 ing growths in shallow bottoms. 



Mature individuals measure nearly 3 mm long by 0.5 mm wide and 

 consist of 27 to 39 segments. The dorsum is concealed by the broad 

 overlapping paleae. The prostomium is quadrate in outline, followed by 

 a larger glandular caruncle overlying the first visible segment. The 4 

 eyes are large, in rectangular arrangement, and the median antenna is 

 inserted at the frontal margin of the lobe, in front of the anterior eyes. 

 The paired antennae are similar to the median one but inserted farther 

 forward and ventrally. The paired palpi are broad, elongate oval, 

 directed forward. 



The first segment is asymmetrical in that the ventral cirrus of the 

 right side is lacking ; both dorsal and ventral cirri of this segment resemble
