92 PHYLLODOCE RUBIGIXOSA. 



Tauber 1 (1879) adopts the opinion that the Phyllodoce teres, P. pulchella, P. badia, 

 and P. BinJcii of Malmgren are only varieties of this species ; and, still further, that the 

 Phyllodoce laminosa of Savigny and Aud. and Edwards, the P. lamelligera of Johnston, the 

 P. remex, Dalyell, P. groenlandica, GErsted, P. citrina, Malmgren, P. mucosa, (Ersted, and 

 P. assimilis, (Ersted, are all one and the same species. There is no doubt that several of 

 these, such as P. citrina, P. mucosa, and P. groenlandica, are very closely allied.

 fig. 25— tail; Plate LXVIII fig. 9— foot; Plate LXXVII, figs. 8 and 8a— bristles. 



Specific Characters. — Head small, rounded, with two large eyes. Anteriorly are 

 four proportionally large tentacles. Two vibratile grooves (nuchal organs) posteriorly. 

 Buccal segment with a pair of tentacular cirri; second segment has two pairs with 

 bristles ; third segment carries the fourth pair, and a rudiment of a foot with bristles and 

 a minute ventral cirrus. 



Body four inches long and upwards, terminating in two fusiform cirri. From the third 

 to the last segment the middle of the dorsum is marked by green or blue bands, parallel 

 and longitudinal, agreeing the one with the other. Proboscis papillose anteriorly and 

 with eight large papillae at the entrance to the stomach. The large cordiform and 

 imbricate dorsal cirri are throughout of a fine red colour. These organs are rounded, 

 cordate anteriorly, and carried on a short ceratophore, broadly cordate and pointed in the 

 middle of the body, cordate and still more pointed as well as smaller posteriorly. From 

 a median streak extending from the ceratophore parallel lines radiate to the circumference, 

 and many have touches of dark pigment. Setigerous region a short blunt and bifid 

 cone supported by a single translucent spine, and the bristles are slightly curved towards 

 the end of the shaft, which is truncated and dilated, a little bevelled, and has traces 

 of spinous strias ; terminal piece short or of moderate length, finely serrated, tapered and 

 often bent at the tip. Ventral cirrus about a fourth the size of the dorsal, reniform, 

 somewhat more pointed posteriorly.

Habitat— This finely coloured species was first found by De St. Joseph in dredged 

 material at Dinard, and subsequently by Allen in dredgings from various grounds near 

 Plymouth. 



Head (Plate XL VII, fig. 4) small, rounded, inserted on the buccal segment, 

 not indented posteriorly, with two large eyes. Anteriorly are four proportionally large 

 tentacles. De St. Joseph describes two vibratile grooves posteriorly, as in other 

 Phyllodocidas, and which he thinks analogous with the nuchal organs of Syllids and 

 Eunicids. The buccal segment bears a pair of tentacular cirri; the second segment has
