46 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 7 



copper-colored stout setae (pi. 6, fig. 77), disposed in 4 or 5 irregular 

 longitudinal rows, emerge above and below the aciculum. The dorsal 

 cirrus is inserted on a broad, basal cirrophore, its style long, slender, 

 extends distally beyond the terminal ends of the setae. Ventral cirri are 

 short, cirriform, tapering, and do not extend distally to the end of the 

 neuropodium (pi. 6, fig. 75). 



Nephridial papillae are cylindrical, present between segments 7 and 

 25, or to the second last setigerous segment. Anal cirri are long, slender, 

 about as long as the last 4 segments. 



These individuals resemble Lepidonotus pomareae Kinberg, from 

 the Hawaiian Islands. Both have deep, truncate neuropodia, the elytra 

 with heavy marginal fringe including a postectal tuft. In the Panama 

 form, however, the elytra are conspicuously covered with numerous, 

 large headed, high tubercles, the sixth pair of elytra are rectangular, not 

 triangular, and the total length is over 35 mm as against 13 mm speci- 

 fied for L. pomareae. 



Holotype. — AHF no. 5. 



Distribution. — Bahia Honda, Panama. In depths of 15 to 50 fms.

Length to 80 mm or over; number of segments over 72. Dorsum 

 with transverse dark bands across the middle of the segments, and a 

 broad band, almost as wide as the segment is long, over the elytrophoral 

 area, median to the parapodial base. Parapodia are pale, prostomium 

 pale rust color; the elytra are dusky on their proximal halves, pale along 

 their outer portions. 



The prostomial lobes are well separated anteriorly. The 4 black 

 eyes are small and limited to the posterior half of the prostomium. 

 Palpi are very long, extending distally far beyond the antennae (pi. 8,
