68 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 7 



The prostomium is wider than long, with 2 pairs of black eye spots, 

 the anterior pair at the frontal margin of the prostomium, concealed by 

 the prostomial antenna. They are larger than the posterior eyes, and 

 spaced a little nearer together. The posterior eyes are immediately be- 

 low the lateral base of the median ceratophore. 



Branchial cirri are minute, papilliform, on the first elytrophore (seg- 

 ment 4), but more or less subequal more posteriorly. The elytra are 

 imbricated, completely covering the dorsum. They are fimbriated along 

 their outer, lateral margin, and some fringes continued submarginally 

 (pi. 17, fig. 209), the anterior margin slightly excavate. Many of the 

 posterior elytra have 3 to 5 larger, simple spines (pi. 17, fig. 210) in 

 a row near the posterior border, in addition to many smaller, similar 

 spines. All of the spines are higher than broad at their base (pi. 17, 

 fig. 208). 



Parapodia, from the second, are conspicuously fimbriated in the 

 first 10 or more segments. The fimbriae are long, papillar, bordering 

 the setal and acicular fascicles (pi. 17, figs. 203, 206). They are present 

 more posteriorly, but in diminishing numbers and sizes. 



The first parapodium has a long slender dorsal cirrus, more than 

 twice as long as its ventral cirrus. A shorter, clavate cirrus, dorsal and 

 anterior to the dorsal cirrus, represents the transposed prostomial an- 

 tenna (pi. 17, fig. 207). The setae are all of one kind, long, slender, 

 capillary, minutely serrated, the supraacicular about twice as long and 

 numerous as the subacicular setae. 



The second parapodium has 2 or 3 superior composite setae with a 

 long, spinose shaft, and a 5 or 6 articled appendage, the tip obscurely 

 bifid. The other setae resemble those in more posterior parapodia. From 

 segment four, there are simple, spinose setae (pi. 17, fig. 211) in the 

 anterodorsal position of the neuropodial fascicle accompanied by slender 

 composite setae (pi. 17, fig. 204). The median (pi. 17, figs. 212, 213) 

 and inferior setae (pi. 17, figs. 205, 215) have a heavy shaft, with few, 

 or mostly no, serrations, and a rapidly tapering appendage which is 1 

 to 5 articled, and terminates in a poorly marked bifid tip (pi. 17, figs. 

 212, 213). 



The notopodia, from the second, are at first notably smaller than 

 the neuropodia (pi. 17, fig. 206), but from the tenth segment the noto- 

 podium becomes increasingly larger and surpasses the neuropodium (pi. 

 17, fig. 216). Ventral cirri are tapering, with a terminal lobe (pi. 17, 

 fig. 206).
