The prostomial antenna is dendritieally branehed. Branehiae num- 

 ber about 10 pairs. Dorsal eirri are long, very slender and threadlike, 

 eontinued on segments through the postbranehial regions. Parapodia 

 have only slender, distally pointed setae, as in the subgenus Aedicira. 

 This speeies occurs frequently with A. lopezi rubra, below, from which it 

 differs in being white instead of rust-colored. 



Aricidea (Aedicira) , unknown species 



San Diego trench, in 768 m (2). 



Santa Cruz en, in 623 m (6) . 



Specimens from San Diego trench measure less than 10 mm long; 

 the body narrows abruptly behind the branchial region. Setae are all 

 capillary, as characteristic of the subgenus. The prostomium is short 

 and truncate in front. Its median antenna is slender and inconspicuous. 

 Branchiae number 9 pairs; they are first present from the fourth 

 setigerous segment and those of the second to fourth pairs are largest; 

 thereafter they diminish in size to the last smallest pair. Large white 

 ova are present in the body behind the branchial segments. 



Specimens from Santa Cruz canyon are small, white, and measure 

 6 to 8 mm long and about 0.3 mm wade. The body is widest in the 

 region of the second to fifth branchial pairs. The prostomium is bluntly 

 depressed, conical and lacks eyes. The median antenna is slender,
