112 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL.22 



Subgenus AEDICIRA Hartman, 1957 



Aricidea (Aedicira) ramosa Annenkova, 1934 

 Aricidea ram osa Annenkova, 1934, pp. 657-658, fig. 3A. 

 Hartman, 1957, p. 327. 



Single specimens come from Santa Catalina and San Nicolas Basins. 

 In each the prostomial antenna is dendritically branched as originally 

 described. The species is more widely reported from Arctic seas in 44 to 

 2400 meters (Annenkova, 1934). 



Subgenus CIRROPHORUS Ehlers, 1908 



Aricidea ( Cirrophorus ) aciculata Hartman, 1957 

 Hartman, 1957, pp. 323-324, pi. 43, fig. 4. 



Single specimens come from samples in San Nicolas and Tanner 

 Basins. They are easily identified by the projecting acicular spines present 

 in notopodia of postbranchial segments. The specimens are pale and less 

 than 10 mm long. The species is more widely known from shallower 

 bottoms of southern California (Hartman, 1957, p. 324). 



Aricidea (Cirrophorus) furcata Hartman, 1957 

 Hartman, 1957, pp. 324-325, fig. 6. 



This species was found only in a sample from Long Basin but it may 

 be expected in other, shoreward bottoms. It is easily distinguished from 

 A. aciculata (see above) in that the body is red or rust-colored instead 

 of white; branchiae are more numerous and furcate setae are conspicuous. 

 Aside from the type locality in the San Pedro area, it has been more 

 extensively collected on shelf and slope depths of southern California 

 (unpublished records). 



Aricidea spp. 



A specimen from Patton escarpment has deep yellow pigment dis- 

 persed over most of the body and the prostomium has eyespots. A posterior 

 end from Tanner Basin has an anal end with a plaque. Both are too 

 fragmented to characterize. 



Family SPIONIDAE 



Eight species in four genera have been identified. They may be 

 recognized as follows:
