110 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL.15 



Parapodial lobes are lamellar but not prolonged. The presetal lobes 

 are short and broad, postsetal ones are longer but only slightly or not at 

 all surpassing the acicular lobe. The latter is broadly rounded (fig. 3) 

 with acicula projecting only slightly. 



Setae are long and flowing; they appear dusky in mass against the 

 pale body. Preacicular setae (figs. 6 and 9) are barred and much the 

 shorter except in anterior segments, where they are longer, stronger and 

 coarser than their corresponding postacicular setae. After the origin of 

 the interramal cirrus the barred setae are rapidly smaller and more 

 slender than postacicular setae. The distal free part of postacicular setae 

 is flattened and delicately serrated at the outer edge (figs. 4, 5). The 

 ornamentation is most developed on setae in inferior and superior posi- 

 tions of the fascicle. 



N. glabra is characterized for having interramal cirri first present 

 from segment 6 or 7 and then not well developed until about segment 

 16. The proboscis has only 2 or 3 papillae in a row in the subterminal 

 series, and the middorsal one is very conspicuous. Parapodial lamellae 

 are weakly developed throughout; acicular lobes are broadly rounded. 



Specimens reported as N. malmgreni Treadwell (1914, p. 192) 

 from San Diego Bay, California, have been reexamined and are here 

 referred to N. glabra.
