290 Mr. J. W. Piyde on Annelida PoJychceta 



This annelid occurs at thirty-one stations, was found at 

 various depths with different apparatus, and the 649 examples 

 ■were taken along with 755 tubes. There are young, half- 

 grown, adult, and mature female forms ; while the tubes, 

 most of which are entire, show their valvular condition very- 

 well. There is, indeed, a wonderful abundance of this species 

 in the North Sea, and the records outclass those of the 

 German North Sea investigations, whose representative, so 

 far as number is concerned, is Onuphis conchylega, another 

 Eunicid. 



Again, no lists of Synonyms have been given, but they 

 can be obtained from Prof. M'lntosh's ' Monograph^ (vol.ii. 

 part i. 1908, and vol. ii. part ii. 1910) under the heads of 

 the various species. The specimens were those belonging 

 to the collection handed over to Mr. W. Small, M.A., B.Sc, 

 by Prof. D^Arcy Thomson, a prominent member of the 

 Scotch Fishery Board. In addition, I have to thank Prof. 

 M'lntosh for his kindness in giving me, from his own 

 collection, a typical series of slides of each group. 



Family Syllidae. 



Genus Syllis, Savigny, 1820. 



SyUis cornuta, H. Rathke, 1843. 



One entire specimen and one anterior fragment were 

 dredged at Station 7, lat. 61° 06' N., long. 2° 1' E., in 

 15 fathoms. It has been found off the Hebrides, in 

 St. Magnus Bay, Shetland, off St. Andrews in deep water, 

 off Bundoran, Donegal, and Berehaven, and extends to the 

 Mediterranean shores of France, Spitzbergen, Madeira, and 

 South Africa, but it is not recorded from Japanese waters. 

 As details of the German North Sea Investigations regarding 

 this family have not yet come to hand, no comparison can 

 be drawn. 



The head corresponds with the characters entered in the 

 Monograph. 



The body of the complete annelid measures a little over 

 three-fourths of an inch in length and has about 70 segments. 

 Other writers give the body about one inch long, and having 

 about 100 segments. The colour is yellowish white and 

 dark brown bands appear at the junction of the segments. 

 Along the dorsum there is a pale yellow line in the median 

 region, the line being more distinct in the tail. The 

 ventral surface is much lighter in hue than the dorsal. 



The feet are characteristic of the species and agree with
