This species, unlike most of the genus, is small and intertidal. A 

 complete individual (station 1450-42) consists of 175 segments and 

 measures 70 mm long and 1 to 1.5 mm wide. Most of the other in- 

 dividuals consist of only 130 to 150 segments and the length may attain 

 only 50 mm or less. The body is slender and filamentous seen with the 

 unaided eye. Under magnification it is seen to taper gradually forward 

 to a long, conical anterior end and prostomium. At the parapodial 

 change the body widens perceptibly and is then almost uniformly broad 

 and depressed. Segments (preserved) in both anterior and posterior 

 regions are uniannulate. The change from uniramous to biramous seg- 

 ments is transitional, through segments 36 to 44. 



In life the color of the body is dark or tawny yellow to yellowish 

 tan. Some of the pigment and its pattern persists through preservation. 

 The prostomium is pale but body segments are marked by 3 longitudinal 

 rows of yellowish brown, segmentally arranged spots on both dorsal and 

 ventral sides. An oval area occupies the middorsum and the midventrum 

 of each segment and there are paired spots over the parapodial ridges. 

 Intersegmental furrows are pale. The distal ends of parapodial lobes 

 and cirri are dark yellow. 



The prostomium is long and conical (fig. 1) ; it consists of 8 (or 

 9) rings; the distalmost ones are not clearly separated from each other. 

 A single pair of eyes, visible in dorsal view, is embedded in the basal 

 ring. The 4 terminal antennae are short and slender but distinctly 

 biarticulate ; each has a tiny distal article. The basal ring is somewhat 

 longer and wider than its proximal ring. 



The proboscis is long and cylindrical. It is pale except for the dark 

 chevrons and paragnaths. Under low magnification its surface appears 

 covered with coarse papillae, marking the distribution of proboscidial 

 organs. The chevrons (fig. 5) consist of 16 to 18 V-shaped pieces on a
