POLYGHiETA— BENHAM. 5C 



Family PHYLLODOCIDiE. 

 Sub-family Phyllodocin^. 

 Genus Phyllodoce Savigny. 

 Phyllodoce madeirensis Langerhans. 

 Langerhans (1880), p. 307, pi. XVII, fig. 44. 

 Willey (1902), p. 270, pi. XLII, fig. 5 ; pi. XLIV, fig. 7.

Four individuals of this widely distributed species were obtained in dredgings 

 in 25-120 fathoms. These are larger than the type, which only reached a length of 

 70 mm., with 105 segments, and than those described from the Antarctic by Willey. 

 The present specimens attain a length of 190 mm., with nearly 300 segments. The 

 greatest width of the body is 2-5 mm. to 3 mm., and over the parapods 6 mm., and does 

 not vary much throughout the length. 



The colom-, which Langerhans found to be green in life, is in the preserved worms 

 in some cases pale brown, with the dorsal cirri rather darker ; in other individuals pale 

 grey, which owing to ii-idescence appears silvery, with pink cii-ri— a pale but decided 

 pink. This one is mature, and contains eggs. 



The tentacular cii-ri are arranged, as Willey has described, and as Ehlers has con- 

 firmed ; the longest reaches to the 10th or 12th segment, the second ventral is about 

 half this length. Although Langerhans wrongly allocates these cirri in his text, yet 

 his figm-e seems to show their distribution quite clearly, and is more informative than 

 Willey's figure. 



The pharyngeal papillae have the characteristic arrangement, which is very 

 evident in one of om- specimens, in which the pharynx is everted. 



Localities. — 



Station B, 25 fathoms. 



Station D, 45-50 fathoms. Distended with eggs. 



Station 8, 120 fathoms. 



Distribution.— MaQleh-a. (Langerhans), Juan Fernandez, South Georgia, Kaiser 

 Wilhelm II Land (Ehlers), Cape Adare (Willey). 



Remarks. — This is rather a remarkable range, and the much larger dimensions of 

 these Antarctic specimens raises the question as to the specific identity, which 

 is mainly upheld by the characteristic arrangement of the pharyngeal papillte. 

 Another species, P. medipapiUata, described by Moore (1909, p. 237), also has 

 the median row of 4 or 5 papilla, with six lateral rows on each side, containing 

 9 in the ventral and 12 in the dorsal rows. This occurs on the coast of Cali- 

 fornia.
