Genus Eulalia Savigny, 1820 



Hypoeulalia Bergstrom, 1914; type (original designation): Hypoeulalia bilineata 

 (Johnston, 1840). 



Type (designated by Bergstrom, 1914, p. 76): Eulalia viridis 

 (Linne, 1767). 



Both species have the body elongate, slender, linear, convex dor- 

 sally, flattened ventrally, attenuated at both ends. Prostomium 

 suboval, slightly constricted just posterior to origin of four subequal 

 frontal antennae, with 2 eyes of moderate size close to posterior 

 margin (fig. 19a). All 3 tentacular segments visible dorsally. Ten- 

 tacular cirri 4 pairs, cylindrical, fusiform, upper 2 pairs longer. 

 Parapodia uniramous, slightly bilabiate distally; neurosetae com- 

 pound. Dorsal cirri longer than wide. Proboscis long, cylindrical, 

 with surface densely covered with rounded to cylindrical papillae 

 (fig. 19a). 



Key to the New England Species of Eulalia 



1. Dorsal cirri elongate-lanceolate, pointed distally (fig. 196). Prostomium 

 with median antenna subequal to frontal antennae (fig. 19a). Green- 

 ish E. viridis 



Dorsal cirri thick, short, oval-obtuse, rounded distally (fig. 206). Pro- 

 stomium with median antenna very small and slender, smaller than frontal 

 antennae (fig. 20a). Usually greenish with lateral longitudinal dark
