NO. 3 hartman: polychaetous annelids 211 



is widest in the region of the eyes and tapers gradually posteriorly. The 2 

 eyes of a side are fused to form a single pair of elongate spots at the sides 

 of the anterior end of the ventral lobe. Branchial filaments are bifid. 



E. bicirrata resembles E. notialis Ehlers (1901, p. 38) from the 

 Straits of Magellan in having bifid branchial filaments. In the latter, 

 however, the distal end of the serrated setae is proportionately much 

 longer than in E. bicirrata (pi. 32, figs. 22, 23). Also, in the latter the 

 bifurcated dorsal setae have a noticeable thickening on the main fang (pi. 

 32, fig. 21). 



Distribution. — Alaska, south to southern California, in 18 to 369
