tentacles, the terminal joints of the tentacular cirri, the ventral cirri, 

 and the margins of the 'dorsal cirri, are light brown in color, while 

 the cirrophores of the tentacular cirri, and the median areas of all 

 dorsal cirri are dark brown without any trace of iridescence. 



Posteriorly the body narrows very decidedly, the anal somite being 

 rather prominent in comparison with the ones immediately preced- 

 ing it. In specimens which seemed entire I could find no trace of 

 anal cirri. 



The parapodium has a setal lobe with anterior and posterior 

 lips, the latter being bifid. (Fig. 23.) The dorsal cirri are thick 

 and firm (in preserved material), and overlap one another pos- 

 teriorly, leaving a large part of the dorsal surface of the animal 

 uncovered. The setae form a single vertical row. 



The setae are all compound, of the type characteristic of this 

 genus. (Fig. 24.) At the apex of the basal joint are some short 

 spines. The terminal joint is relatively short and thick, with very 

 minute denticulations along one edge. 



Collected in Suva Harbor, Fiji, and one specimen is in the col- 

 lection from Japan. 



The type is Cat. No. 19144 of the U.S.N.M. 



PHYLLODOCE FUSCA-CIRRATA, new species 



The type specimen is 150 mm. long, with a greatest body width 

 of 3 mm. about one quarter of the length behind the anterior end. 

 Posteriorly it narrows very decidedly. In the preserved material 

 the main color features are the iridescence of the anterior region and 

 the dense brown pigmentation of all cirri on the posterior region 

 of the body. 



The prostomium (fig. 25) is about 1 mm. in diameter on the 

 posterior border, and has a shallow median notch on its jDosterior 

 margin, into which fits a small nuchal organ. From each rounded 

 postero-lateral angle of the prostomium the lateral margins diverge 

 slightly to the corresponding antero-lateral angle, the large eye on 

 either side lying about its own width nearer the posterior than the 

 anterior angle. The antennae are situated at a distance of about 

 twice their own diameter from the anterior margin of the prosto- 

 mium and extend as far as the posterior margin of the eyes. They 

 are approximately equal in size. The anterior margin of the pro- 

 stomium is rounded and prominent, the median antero-posterior 

 diameter is about equal to the greatest prostomial width. A rounded 

 nuchal organ on either side lies just ventral to the eye. 



The longest tentacular cirrus is the dorsal one of somite one, its 

 cirrophore extending over two somites and its terminal joint reaching 

 somite 10. The tentacular cirrus of somite 2 reaches somite 9, the
