38 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 27 



digitate, shorter than the lobe and inserted near its middle. The pro- 

 stomial lobe consists of 3 sections set off by a pair of diagonally oblique 

 lines extending from the midlength at the sides to the posterior margin 

 of the lobe. 



The first postoral segment is the first setigerous one; its parapodia 

 are biramous and provided with simple, distally pointed setae, as are all 

 others. Branchiae are present from the fourth setigerous segment; the 

 first pair are largest, and there is gradual decrease in size to the last, 

 or tenth pair. Branchiae taper distally without an abruptly slender end; 

 they are much larger than the parapodial postsetal lobes, straplike and 

 directed upward and forward. Notopodial postsetal lobes are slender, 

 digitate, present on all segments. Ventral cirri are slender, incon- 

 spicuous, digitate lobes, and visible on all parapodial segments. 



Aricidea (Aricidea), nr fauveli Hartman, 1957 



Tanner en, in 496 m ( 4 ) . 



These specimens differ from Aricidea fauveli from the Mediter- 

 ranean Sea in the following respects: branchiae number 10 instead of 

 12 to 50 pairs; eyes are absent. They agree in that posterior neuro- 

 podial setae are acicular and have a long, slender arista inserted sub- 

 distally. Notopodial setae are entirely slender and capillary. Dorsal 

 cirri are very long and slender. The prostomial lobe is elongate, triangu- 

 lar, provided with a median antenna that is long, slender and tapers 

 distally.
