Eunice fasciata, Risso, 1826. 



At Station 23 a, lat. 59° 51' N., long. 1° 12' E., and at a 

 depth of J 15 m.j three incomplete specimens of this species 

 were trawled in the month of July 190G. This annelid, 

 however, is found in the neighbourhood of Guernsey *, off 

 the Hebrides, off Inverary. J. G. Jeffreys found it in 

 IGO fathoms 55 miles west of Valentia, Irelaiul. It was 

 obtained in the 'Porcupine' and ' Challenger' Expeditions, 

 and was procured by De Quatrefages and De St. Joseph off 

 the shores of France. There is, however, no record of it 

 having been found in Japanese waters. 



The head is small when compared with that of E. norve- 

 g'lca or E.jloridana, and bears two massive palpi, which are 

 fused at the base and are separated by a deep notch in front. 

 The tip and the ventral surface, which has a deep groove, are 

 much lighter in colour than the rest of the body. There are 

 five tentacles, which are fairly long, taper very slightly 

 towards the tip, and have transverse bars where the crena- 

 tions appear. The longest is the median one, and behind it 

 are two pale-coloured spots, while in front there is another 

 spot ; but those mentioned by the Monograph as occurring 

 at the base of the lateral tentacles are absent. The eyes are 

 at the base of inner (posterior) paired tentacles. 



The adults of this species attaiu a length of from 6 to 

 9 inches, and are russet-brown in colour, which is deeper on 

 the dorsum than on the ventrum. The dorsal blood-vessel 

 appears as a very dark streak, and white patches occur near 

 the bases of the feet. None of the present specimens show 

 iridescence. The body tapers to the posterior end, where it 

 terminates in two moderately long anal cirri, which, like the 

 tentacles, have transverse bars and are somewhat crenatcd in 

 appearance. On the second segment the tentacular cirri 

 arise, and reach forward to the bases of the palpi. The 

 cirri are more finely tapered than the tentacles, but in the 

 specimens of this collection there are no transverse olive- 

 coloured bars as are mentioned in the Monograph f. 



The j)roboscis is not extruded in any, but is armed with 

 strong chocolate-coloured maxilUe. Prof. M'lutosh adds :
