122 Prof. M'lutosli's Notes from the 



tion of its approach to the fused cirrophore. Toward tlie tip 

 of the tail, again_, hoth the setigerous lobe and the ventral 

 cirrus have diminished in bulk, the latter especially being 

 longer and more slender, and its tip often projects beyond 

 that of the setigerous lobe, the bristles in which are fewer 

 and shorter. 



This form generally resembles Eteone depressa, Malmgren, 

 and especially in the structure of the feet and bristles, but 

 it differs in the presence of the " boss " or rudimentary 

 tentacle at the posterior border of the prostomium. If the 

 various authors who have examined it, however, had only 

 seen spirit-preparations, it is possible that it may have been 

 overlooked. Hitherto it has been found, amongst other 

 places, at Bellsund, Spitzbergen, Greenland, Nova Zembla, 

 and the Murman Sea. In his brief note on the species 

 Theel * states that the head differs from Malmgren's outline, 

 and he gives a corrected figure. Fauvel f; another able 

 investigator of the Annelids, considers that this species may 

 be identical with Etione spetsberyensis, Malmgren, but, as 

 indicated in the preceding remarks, there are reasons for 

 kee^Ding them separate. 



4. On Nereis zonata, Mgrn., in Britain. 



Nereis zonata, Malmgren, is a form which, though not 

 uncommon in northern waters, as in the cruise of the 

 ' Valorous,^ appears to be rare in Britain. 



Malmgren received it from Greenland and Spitzbergen. 

 and Marenzeller and others from North European and 

 North Asiatic regions. The head resembles that of Ntreis 

 pelagica in regard to general shape, but the eyes are some- 

 what larger and the tentacles and tentacular cirri are longer 

 and more slender. A dark band of pigment runs in the line 

 of the eyes, and a band of white passes forward between 

 them. The body has a distinctive coloration, viz. a pale 

 reddish-brown hue in spirit, though Malmgren adds yellowish 

 or bluish to the reddish brown. The arctic examples from 

 the ' Valorous '' were distinctly banded transversely, a feature 

 very evident in young specimens. It is terminated poste- 

 riorly by slightly longer cirri than in N. pelagica, though 

 much reliance need not be put on this feature. The maxillae 

 of the proboscis have the same number of teeth, those of 

 N. pelagica perhaps being usually more distinct, and the tip,
