The specimens from Sta. 4652 vary in length from 28 to 34 mm. In a 

 specimen 34 mm. long the greatest width, exclusive of the parapodia, is 3 mm.; 

 inclusive of parapodia, without setae, 6.2 mm., and to tips of setae, near 8 mm. 

 The number of somites in these specimens is mostly from forty-eight to fifty. 

 The maximum width is near the fourteenth somite, from where the body nar- 

 rows moderately cephalad and narrows continuously caudad, the posterior end 

 being acutely pointed. 



The general color of the body is greyish brown, most showing more or less 

 distinctly narrow transverse stripes of darker brown, one on each somite extend- 

 ing between the opposite parapodia. There is also a dark, middorsal, longitudinal 

 Une. A more elevated area over each ventral ganglion appears somewhat paler. 

 The cirri are also lighter in color. The dorsal segmental glands at the bases 

 of the parapodia have their ectal fold very dark, appearing as a series of deep 

 colored spots along each side. The ventral glands are pale, or may also be dark, 

 and then form on each side a ventral series of dark dots. Dorsally, a dark spot 

 may be present on the prostomium at the mesal edge of each eye. One speci- 

 men is lighter, more yellowish in color. 



So far as can be judged, the structure of proboscis, eyes, and tentacles, as 

 well as of the parapodia, appears to be typical, though, unfortunately, I have 

 been imable to compare with Atlantic specimens. The tentacles seem to vary 

 somewhat in relative and actual size. The cirriform appendages on the para- 

 podia are conspicuous, tapering distally, with the two in each case equal or 

 nearly so. 



Two specimens from Sta. 3790 are accompanied by a field note to the 

 effect that in Ufe the dorsum is "cream with a transverse brown band on each 

 segment. Parapodia cream yellow." The dark spot at base of each para- 

 podium is also noted. 



Two specimens from Sta. 4655 are also much lighter in color than those
