Description. — Length up to 100 mm., width up to 2 mm., segments 

 up to 150. Second tentacular segment with setae. Longest tentac- 

 uhir cirri extend to setiger 5. In addition to the compound neurosetae, 

 there may be long, delicate capillary setae extending far beyond the 

 other setae; capillary setae mixed in with the other setae but not in 

 separate bundles as in some of the Syllidae; evidently an epitokous 

 condition associated with sexual forms. Color, in life: variable in 

 coloration, gray, j^ellow greenish or olive brown, usually with lateral 

 brown bands on each side and darker spots at bases of parapodia, 

 both above and below; preserved: brownish iridescent, sometimes 

 showing darker longitudinal bands, dorsal cirri dark velvety brown, 

 almost black.
