Aricidea (Cirrophorus) branchiata Ehlers, 1908 



Cirrophorus branchiatus Ehlers, 1908, pp. 124-126, pi. 17, figs. 5-9. 



The prostomium is depressed conical and without eyes. The median 

 antenna is short and cirriform, its length less than half that of the 

 prostomium. The first 4 segments are prebranchial. Branchiae are 

 present on about the next 25 segments; they are short, cylindrical and 

 resemble in appearance the corresponding notopodial postsetal lobes. 

 Neuropodia of abdominal segments have heavy acicular spines that 

 project from the end of the parapodial lobe. 



Distribution. — Aricidea {Cirrophorus) branchiata comes from Agul- 

 has Bank, southern Africa, in 117 meters in gray sand. Southward 



(1955) recorded it from the British Isles, and Berkeley and Berkeley 



(1956) from Washington.
