with a pair of winglike mandibles, with anterior part flared, calcare- 

 ous and more or less toothed. Maxillae with a pair of short bilobed 

 maxillar3'^ carriers; maxillae i, the forceps, in the form of prominent 

 hooks, with 1-2 longitudinal interlocking teeth at the base. 



Key to the New England Species of Eunice 



1. Acicula and acicular setae yellow. Branchiae begin on about setiger 3 (3-5), 

 continuing to about setiger 40; middle and posterior regions without bran- 

 chiae; where best developed, branchiae extend beyond the dorsal cirri, 

 with 8-22 filaments per branchia E. pennata 



Acicula and acicular setae black. Branchiae begin on about setiger 8 (7-10), 

 continuing to near posterior end; where best developed, branchiae about as 

 long as the dorsal cirri, with 3-12 filaments per branchia (fig. 63/).

Description. — Length up to 200 mm., width up to 12 mm,, seg- 

 ments numerous. Prostomium with occipital antennae nearly 

 smooth or with irregular rings or fluted distally. First tentacular seg- 

 ment 3 to 4 times longer than the following. Branchiae begin on 

 about setiger 8 (7-10), continuing to near the end of the body. Bran- 

 chiae about as long as the dorsal cirri, pectinately branched, with 

 usually 6-8 filaments (3-12) per branchia. Parapodia with acicula 

 and subacicular hooks black. 



Maxillae of proboscis black; maxillae ii each with 5-7 teeth; right 

 maxilla iii with 7-10 teeth; left maxilla iii missing; maxillae iv with 

 4-7 (right) and 7-10 (left) teeth; maxillae v and vi each with a single 

 tooth. Color: pinkish, brownish or black, spotted with bro\vn; 

 sometimes a pale collar on setiger 4 (Fauvel). Tube: papyraceous, 

 parchmentlike, cylindrical, irregularly bent, rough, with side open- 

 ings at the angles, often branched. The tubes may be more or less 

 covered with attached hydroids, sponges, anemones, ascidians, etc. 

 A young specimen of 37 setigers had the branchiae on setigers 9-19, 

 consisting of a single filament; subacicular hooks began on setiger 15; 

 antennae distinctly articulated. 



Biology. — Dredged on bottoms of sand, mud, and various combina- 

 tions of mud, sand, gravel, broken shells, and dead corals. They may
