Most specimens are small, between 25 to 35 mm long. Branchiae are 

 present from the third parapodium with one filament, increase to 4 or 5 

 filaments between segments 18 to 25, thereafter decrease again to 2 or 3 

 filaments by the thirtieth parapodium, and are more or less abruptly ab- 

 sent after the thirty-sixth (based on individuals from the eastern Pacific). 

 The prostomial antennae are slender, long, with cylindrical articles, each 

 about 2 or 3 times as long as broad. Peristomial cirri are more or less 

 annulate. Acicula and subacicular hooks are pale yellow; the latter are 

 distally tridentate. 



E. vittata is grossly distinguishable from E. rubra (above) and its 

 closely related species, E. antennata (above), in having long-articled, 

 slender prostomial antennae instead of strongly moniliform ones. 



Distribution. — Both sides of the Western Hemisphere, in tropical 

 and subtropical waters, from Bermuda, through the West Indian region 

 and Trinidad, and from southern California, south to Pacific Panama. 

 Its bathymetric range is from intertidal to 55-110 fms.
