region. The prostomium is pale with a dark, median, longitudinal 

 stripe. The white branchial cirri have narrow black rings. Parapodial 

 tentacular filaments posterior to the branchial region are dark with a 

 subdistal white ring, and a terminal dark point. 



The setae are pale, inconspicuous, and include pointed capillaries 

 in both rami of the first 7 segments. More posteriorly, pointed setae 

 alternate with thicker, uncinigerous setae. The latter are slightly 

 curved (fig. 3, /) and terminate in a blunt point. 



Cirratulus nigromaculata Treadwell is preoccupied by Grube (1870, 

 p. 504) for a species from the Red Sea. A new name is therefore 

 proposed. 



Distribution. — Panama ; Socorro Island, Mexico. 



OPHELIIDAE 



POLYOPHTHALMUS PICTUS (Dujardin) 



Polyophthahmis pictus Fauvel, 1927, p. 137. 



? Polyophthahmis australis Treadwell, 1914, p. 216. 



Collection. — Station Nos. 3-38, 5-38; numerous specimens. 



Length to 27 mm. ; pigment pattern consists of rust-colored, trans- 

 verse segmental bands dorsally, widest in the first 3 or 4 segments 

 where they almost coalesce, and become narrower more posteriorly. 

 The band is continued on the ventral side but interrupted ventro- 

 laterally along the muscular ridge. There are 12 pairs of lateral eye 

 spots. The prostomium is pale. 



P. australis Treadwell (1914, p. 216), from southern California, is 

 perhaps this same species, since it is known to occur commonly in the 

 littoral zones of southern California. 



Distribution. — Cosmopolitan, in warmer waters. 



ARMANDIA, sp. 



Collection. — Station No. 3-38 ; 1 specimen. 



In a collection with numerous individuals of PolyopJitJialmus pictus 

 (Dujardin). Pale to white except for eye spots. Prostomium with 3 

 black, embedded eye spots. Consists of 36 setigerous segments. The 

 proboscis is partly everted in the form of 8 dichotomously divided 

 lobes, the largest lobes near the middle of the series. The prostomial 

 lobe (anterior to the mouth) measures about as long as the length 

 from the mouth to the fourth parapodium. Lateral eye spots are oval, 

 black, present from between segments 2/3 to 32/33, though a few are 

 missing. Branchiae are cirriform, present from the second setigerous 

 segment to the second last, or 34 pairs.
