serrated, yellow, distally entire, and vary from short, slightly curved, 

 to much longer and nearly straight. Neurosetae are much slenderer, 

 distally entire and hirsute along the shaft. 



They differ from Antinoella macrolepida (Moore, 1906), with large 

 eyes and no prostomial peaks, and from Antino'e anoculata Moore ( 1910) , 

 totally lacking eyes, which are known from great depths off the north 

 Pacific Ocean south to Lower California, Mexico. Antinoella macrolepida 

 is further recorded from Sakhalin, Japan (Uschakov, 1958a, pp. 78-79). 



Genus LAGISCA Malmgren, 1865 



Lagisca lamellifera (Marenzeller) 1879 

 Polynoe (fLaenilla) lamellifera Marenzeller, 1879, p. 115. 



This species was recorded from San Nicolas and Santa Cruz Basins 

 (Moore, 1923, p. 256). Its more extended range includes northern 

 Japan (Marenzeller, 1879). 



Lagisca multisetosa Moore, 1 902 

 Moore, 1902, pp. 267-269, pi. 14, figs. 29-36. 



This species was recorded from Santa Catalina Basin by Moore 

 (1910, p. 341) in moderate depths to 350 fms. Its more extensive range 

 extends from Alaska to western Mexico, in 1400 fms (Moore, 1910). 



Lagisca pedroensis, new species 

 (Plate 3, figs. 1-5) 



Lagisca sp. Hartman and Barnard, this volume, p. 39. 



The type specimen comes from San Pedro Basin (Sta. 2500) ; it 

 measures 21.5 mm long and 4 mm wide and is accompanied by several 

 other smaller ones. The body consists of 40 setigerous segments. The 

 prostomium is one and a half times as wide as long and has distinct 

 peaks; it is deeply incised through its anterior half for the insertion of 

 the median cirrophore. There are 4 black eyes, a pair located at the 

 sides in front of the middle of the lobe, and a similar pair near the 

 postlateral margin of the prostomium. 



Elytra number 15 pairs; they are broadly overlapping across the 

 middorsum and leave the last few segments exposed, as typical of the 

 genus. In shape they are reniform, appear smooth but, when magnified, 

 are seen to have a sparse marginal fringe consisting of long to short
