82 PHYLLODOCE PAEETTI. 



Eisso's genus Eunomia (1826) probably refers to Eulalia or Phyllodoce, and his 

 E. tympana is a reddish form perhaps akin to Phyllodoce rubiginosa. 



The Phyllodoce mucosa of (Ersted 1 may have some relation to a young form of this 

 species. 



In the illustrated edition of Cuvier (1849), Milne Edwards shows a variety with a 

 dark spot at the segment-junction near the base of the cirrus on each side. 



Ehlers (1864) gives an extended account of the structure of this form which he 

 considered different from Savigny's P. laminosa. He points out that the colour of the 

 latter is a beautiful green, that it appears to differ in the form of its bristles, the arrange- 

 ment of the papillaB of the proboscis, and other details. In alluding to this author's views 

 Miss Newbigin leaves the question undecided. 3 



The Phyllodoce Kinbergi of De Quatrefages (1865) would seem to come near this 

 species, if it is not identical therewith. His P. BathJcii s appears also to be a well-marked 

 pale variety. 



Malmgren (1867) considered that Rathke's form though similar did not pertain to this 

 species, which had not yet been found in Scandinavia. 



This seems to be the Phyllodoce marginata of Gosse from Torbay. 



Tauber (1888) is of opinion that P. metadata, Mull, and (Erst., P. Millleri, Leuck., 

 P. teres, pulchella, badia, Rinhii, citrina, groenlandica, incisa, mucosa, and assimilis all 

 belong to Ph. lamelligera, Johnston. Further study may lead to a union of such forms as 

 Phyllodoce lamelligera and P. groenlandica, but it is advisable to leave them separate at 

 present. Ehlers separates P. laminosa, Sav., from P. lamelligera, Johnst. Cznerniavski 

 ranges P. laminosa under the sub-genus Genetyllis. . 



Giard (1890), like Ehlers, separates the Phyllodoce laminosa of Savigny from the 

 P. lamelligera of Johnston, which is rare at Wimereaux, and is, he thinks, near the type 

 of P. Pancerina and P. splendens. So far as British experience goes, the latter suggestion 

 would seem to have slender foundation, but the experienced zoologist of Wimereaux may 

 have reasons — not yet disclosed — for his view. 



Goodrich 4 finds a distinction between the solenocytes of Phyllodoce Paretti, where 

 they are grouped only at the tips of the branches, and those of P. laminosa, in which the 

 cell-bodies are bent round so as to rest on the segmental organs, the latter rather 

 resembling those of Glycera unicornis than those of its nearer allies. In the latter species, 

 also, he says cilia are developed on the coelomic surface between the rows of solenocytes.
