110 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 25 



Length is 18-25 mm. The prostomium is acutely pointed in front 

 and has a pair of transversely elongated eyes at the side, usually per- 

 sisting through preservative. The body is pale to white, thickest in its 

 anterior third, and tapering posteriorly. Yellow acicular neuropodial 

 spines are present from the first parapodium ; they number about 3 in a 

 ramus and are accompanied by 4 or 5 capillary setae in alternating 

 transverse series. Anterior notopodia have capillary setae, and spines 

 are present from about the ninth setiger, accompanied by slender setae. 



Lateral branchiae are inserted immediately above the notopodial ridge 

 in all parts of the body. In posterior segments the space separating noto- 

 podia and neuropodia is reduced and the spines form cinctures about 

 the body. The spines are longest at the upper end of the series and 

 decrease in length ventrally. 



Chaetozone corona in southern California is best represented in shelf 

 depths, and in silty sediments.

 Point, California, in 20^2 fms, green mud (2). 



Length, posteriorly nearly complete, is 10 mm; width at the widest 

 part is 0.8 mm ; number of segments is perhaps not more than 30. The 

 prostomium is depressed, equitriangular in shape and has on either side 

 a transverse series of eyespots, separated middorsally by a narrow space ; 

 the prostomium grossly resembles that of Ctrratulus cirratus (see above). 

 The first 3 segments (buccal region) are long and cylindrical, with 

 their total length nearly twice that of the prostomial length. They are 

 followed by the palpal segment, in which the scars of attachment are 

 visible at dorsolateral positions. The next 9 segments are much shorter 

 and somewhat broader; they have lateral biramous parapodia in which 

 both notopodia and neuropodia are provided with fascicles of slender, 

 long, distally pointed setae. 



From the tenth setigerous segment the body is tapering, the segments 

 are longer and somewhat moniliform. Yellow, acicular spines are first 

 present in neuropodia from the tenth setigerous segment ; they alternate 

 with slender pointed setae. Postmedian segments have 2 or 3 thick, 

 yellow spines and the corresponding notopodia have similar, though 

 slenderer spines, alternating with pointed setae. 



Lateral branchiae arise from the dorsal edge of notopodia and are 

 present on some segments throughout the body. Seen individually, the
