54 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 7 



Genus LAGISGA Malmgren 

 PLagisca multisetosa Moore 



Lagisca multisetosa Moore, 1902, pp. 267-269, pi. 14, figs. 29-36; 1910, 

 pp. 340-341; Berkeley, 1923, p. 215. 



Collection. — 874-38. 2 specimens. 



The material at hand does not permit the certain identity with the 

 species indicated. Moore (1910, p. 341) has already commented on the 

 possible range of variation in this species, and the need for a revision 

 of species belonging to this genus. 



Augener (1913, pp. 207-209) considered Lagisca multisetosa a ques- 

 tionable synonym of Harmothoe aspera Hansen, from the North Sea. 

 Annenkova (1937, p. 152), perhaps at this suggestion, reported H. 

 aspera from the North Sea, and considered L. multisetosa identical with 

 the form from the North Sea. Until more collections are available, it 

 will be difficult to conclude what the relations are between the north 

 Pacific and the north Atlantic forms. 



Distribution. — North Pacific, south to Lower California (Moore), 

 in 40 to 1,400 fms. The type locality was first given as North Green- 

 land, but later corrected to Icy Cape, Alaska (Moore, 1905, p. 525). 



Genus POLYNOfi Savigny, sensu Kinberg 



Body long, consisting of numerous segments. Prostomium harmo- 

 thoid, the lateral antennae inserted ventrally. Elytra 15 pairs, limited 

 to the anterior portion of the body, the posterior segments uncovered. 

 Notopodial setae more or less delicately serrated or quite smooth; 

 neuropodial setae with transverse serrations, tip bidentate or unidentate. 



Polynoe veleronis, new species 

 Plate 10, Figs. 121-127 



CollectioTis. — 405-35, 834-38, 835-38 (Holotype). 6 specimens. 



Length 30 to 35 mm, width 4.5 mm without, 6.0 mm with para- 

 podia; number of segments 50 to 60, the last 18 or more left uncovered 

 by the elytra. General form elongate, depressed, the sides more or less 

 parallel. 



Prostomium harmothoid, the 2 lobes well separated in their anterior 

 halves but only weakly posteriorly, terminating anteriorly in a pair of 

 acuminate prostomial peaks (pi. 10, fig. 121). Eyes 4, small, black, the
