NO, 1 HARTMAN : POLYCHAETOUS ANNELIDS 117 



Leodice monilifer Chamberlin (1919, p. 11) from Laguna Beach, 

 California, may also belong here, since it was characterized as having 

 strongly moniliform prostomial antennae, but branchiae were said to be 

 absent in the posterior region; setal and subacicular structures were not 

 made known. 



Distribution. — E. antennata Savigny is cosmopolitan in tropical and 

 subtropical seas, in intertidal and littoral zones. On the west coast of the 

 Americas it ranges from southern California, south to Ecuador, and west 

 to the Galapagos Islands. On the east coast it has been encountered in 

 the West Indies, south to Venezuela. The bathymetric range, based on 

 the collections, is from intertidal to 100-150 fms.

E. rubra bears striking resemblance to E. antennata (above). Both 

 have distinctly moniliform antennae, similar maxillary parts, tridentate 

 subacicular hooks, branchiae best developed in an anterior region. In E. 

 rubra the acicula and subacicular hooks are also pale, and the latter are 

 distally tridentate. In it, however, acicula are distally somewhat bent, 

 slightly bifurcated (pi. 7, fig. 153), but not hammer headed as in E. 

 antennata; the subacicular hooks are less prolonged in their distal por- 

 tion (pi. 7, fig. 152). Composite hooks are distally bidentate (pi. 7, fig. 

 151), The most notable difference is in the reduction of branchiae in 

 median and posterior regions ; here the number of filaments does not tend 

 to increase after a median region, Monro (1933, p, 59) has pointed out 

 the many resemblances of these 2 species, and doubts whether they should 

 be retained distinct, I retain their separation largely because of this differ- 

 ence in branchial character and acicular tips, as mentioned above. 



Distribution. — E. rubra ranges especially off the eastern coast of the 

 Americas, from North Carolina, south to Brazil, including the Gulf of 

 Mexico ; it is intertidal, to 24 fms, based on these collections.
