papillae just anterior to the first pair of tentacular cirri (may be 

 extended or withdrawn). 



First tentacular segment not visible dorsally; first pair tentacular 

 cirri lateral to prostomium. Second segment with 2 pairs tentacular 

 cirri, without setae. Third segment with fourth pair tentacular 

 cirri, setigerous lobes and ventral cirri. Tentacular cirri unequal, 2 

 longer pairs extending to segments 8-12. Dorsal cirri of median 

 region subquadrangular, with distal ends truncate, extending upward 

 over dorsum (fig. I8,b,d,e). Except for some anterior segments, 

 with a transverse band of long cilia in the middle of each segment 

 and extending onto inner posterior sides of dorsal cirri. Parapodia 

 uniramous, slightly bilobed distally; compound setae with blades 

 tapering to capillary tips (fig. 18c). Pair of anal cirri, cylindrical, 

 tapering. Anterior part of extended proboscis hexagonal, transversely 

 rugose, crowned with papillae; basal part with oval papillae arranged 

 in longitudinal rows (in P. arenae, so crowded, difficult to detect 

 rows) . 



Key to the New England Species of Phyllodoce (Anaitides) 



1. Ventral cirri oval, not pointed (fig. 18d). Body with brownish spots mid- 



dorsally, with diffused brownish longitudinal bands dorsolaterally; dorsal 

 cirri spotted P. (A.) maculata 



Ventral cirri oval with asymmetrical acuminate tip (fig. 18e). Body rather 

 uniformly pigmented greenish, grayish brown, or bluish. 



P. (A.) groenlandica 



Ventral cirri pointed (fig. 186) 2 



2. Middorsum with brown spots, sometimes forming an almost continuous 



longitudinal band. Basal part of proboscis with 6 longitudinal rows of 



papillae on each side (fig. 18/) P. (A.) mucosa 



Dorsum with wide spindle-shaped dark transverse brown bands (fig. 18a). 

 Basal part of proboscis covered with papillae except for narrow middorsal 

 part P. (A.) arenae
