NO. 1 HARTMAN : POLYCHAETOUS ANNELIDS 75 



present from the sixth, instead of the first, setiger; it differs from O. 

 zebra in lacking the greatly prolonged anterior parapodia ; it differs from 

 O. litoralis in having branchiae far more developed, O. peruana was at 

 first thought to be close to O. proalopus Chamberlin (1919, p. 265), but 

 in the latter the ventral acicula are said to be dark brown and the first 

 parapodia cylindrical and very long; also, no composite spinigers have 

 been described for it. 



Holotype. — AHF no. 39. 



Type locality. — Independencia Bay, Peru, in 18 fms (coll. 835-38). 



Distribution. — Independencia Bay and Lobos de Afuera, Peru, in 

 14-18 fms.

O. eremita is most readily distinguished in having branchiae present 

 from the first setiger, with 5 to 7 filaments where best developed; the 

 occipital tentacles have long, annulated ceratophores. 



Distribution. — Though perhaps common off southern California, this 

 species has heretofore been reported from the Western Hemisphere only 

 once, from Elkhorn Slough, California (MacGinitie, 1935). The pres- 

 ent records extend the range from Monterey Bay south to Guatemala, 

 and in the Caribbean Sea to Venezuela and Colombia. It occurs in shal- 

 low water to 49 fms.
