POLYCHAETE WORMS, PART 1 239 



Fiirapodia with lower biiiuUe of coinpound setae both heterogomph 

 spinigeroiis, distally pointed and heterogomph falcigerous with tips 

 bidcntate and hooded (fig. 63(^). .Single lower heavy acicular setae 

 beginning on about setiger 35, prominent, dark, bidentate and hooded 

 distally (fig. 63c). Single dark aciculum in each parapodium and 

 which may project distally in more posterior parapodia. 



Maxillae of proboscis rather weak, light brown in color; maxillae 

 II with 5-8 teeth; left maxilla iii with 7-8 teeth, right maxilla iii 

 missing; left maxilla iv with 3-6 teeth, right maxilla iv with 8-9 

 teeth. Color: pinkish grey or slate colored with bright red branchiae, 

 acicula black. 



Biology.— Found at low water on muddy sand, under stones, in 

 roots of Zostera. Dredged on bottoms of sand, gravel, and stones.

Genus Eunice Cuvier, 1817 



Leodice (Savigny, Ms.) Lamarck, 1818; type (herein designated): Leodice gigantea 

 (Savigny, ms.) Lamarck, 1818^, = E^m^ce aphroditois (Pallas, 1788). 



Type (designated by Hartman, 1959a) : Eunice aphroditois (Pallas, 

 1788). 



Both species represented have the body elongated, thickened and 

 rounded anteriorl}^, somewhat depressed and tapered in middle and 

 posterior regions. Prostomium (fig. 636-) and fused palps bilobed 

 anteriorly, with 5 occipital antennae, the middle one longest, the most 

 lateral pair shortest, with 2 eyes between the bases of the paired 

 lateral occipital antennae (may be hidden by the tentacular segment). 

 The second tentacular segment about the same length as the follow- 

 ing, Avith a pair of short tentacular cirri extending to the base of the 

 prostomium. 



Parapodia with setal lobes rounded to conical, with setae of sev- 

 eral kinds: Upper group with (1) long slender, slightly limbate setae 

 with capillary tips and (2) shorter delicate comb setae; lower group 

 of setae (3) compound falcigerous, with blades rather short, bidentate 

 and hooded; beginning on about setiger 40, (4) with a stout acicular 

 seta with tips bidentate and hooded (unless worn). Dorsal cirri 

 digitiform. Ventral cirri short, digitiforni on first few setigers, becom- 

 ing thick basally wdth short bulbous tips, then becoming digitiform 

 again in far posterior region. Anal end with usually 4 anal cirri, 2 

 slightly more dorsal ones longer, 2 ventral ones small. Proboscis
