12 PEOCEEDINGS OF THE NATIONAL MUSEUM vol. 69 



very darli: green as seen with transmitted light, and numerous 

 small black dots, marking the position of short spines, are scat- 

 tered over its surface. In later somites the pigment is more diffusely 

 scattered though the greater bulk is always toward the dorsal 

 margin of the elytron. Figure 18 was taken of the fourth elytron. 

 The margin is entire. The surface is dotted with short spines, each 

 with a dark central axis when located in the pigmented area but 

 colorless elsewhere. A single row of larger and more distinct 

 spines lies along the colorless margin. 



Collected at Pango Pango, Samoa and one incomplete specimen 

 was found at Suva, Fiji. 



The type came from Pango Pango and is Cat. No. 19142 in the 

 U.S.N.M. 



Family PHYLLODOCIDAE 



Genus PHYLLODOCE Savigny 



PHYLLODOCE PULLA, new species 



A single specimen, measuring not less than 170 mm. in length, and 

 1.5 in body width. Because of the twistings of the body accuracy 

 in measurements of this preserved material is quite impossible. 



The general color effect is that of a light brown. The anterior 

 region of the body is dark iridescent violet but this weakens in later 

 somites and practically disappears by the middle of the body. All 

 cirri and parapodia and the entire ventral surface of the body, are 

 brown in color. 



The prostomium (fig. 19), is cordate in outline with a rounded 

 apex, and with a triangular posterior incision, the latter nearly filled 

 by a large nuchal papilla. On either side of the papilla is a rounded 

 pedicle-like connection between the prostomium and the first somite. 

 One pair of large eyes showing no trace of lenses, lie opposite the 

 anterior end of the posterior incision. The prostomium is light- 

 brown in color, contrasting in this respect with the iridescent violet 

 of the following somites. The tentacles are all alike in form, rather 

 stout, and about one-third as long as the prostomium. The tenta- 

 cular cirri have light-brown cirrophores, the styles being a trifle 

 darker in tint. The longest is the single one carried on somite 2, 

 and it extends to the tenth setigerous somite. 



The parapodium (fig. 20) has a single setal lobe with longer an- 

 terior than posterior lip, and a single acicula. The dorsal cirrus 

 is asymmetrically lanceolate and erect. There is much less differ- 

 ence in the sizes of the dorsal and ventral cirri in this species than 

 in P. vaHegata. (See below.) 



The setae (fig. 21) are slender, the basal joint having a beveled 

 end with a few spikes, the. terminal joint rather long, curved, with 

 teeth along its convex edge.
