THE BRITISH KORTH-POLAR EXPEDITIOJT. 133 



Fam. Sabellid^. 



? Sabella spetsbergensis, Malmgren. 



Trom Franklin-Pierce Bay, in 13-15 fathoms, on a stony bot- 

 tom (Mr. W. C. Hart). The absence of the branchise renders 

 accurate diagnosis difficult. 



This form also occurs in considerable quantity from the stomach 

 oi PJioca barhata, Fabr. 



Ettchone analis, Kroyer. 



From Discovery Bay, lat. 81° 41' K 



In tubes of particles of quartz, fragments of shells, and spines 

 of Echini, with sand-grains and secretion. 



Not uncommon on the shores of the North Atlantic — from 

 Britain to Scandinavia, Spitzbergen, and Greenland. 



ChojSTE iNruNDiBULiFORMis, Kroyer. 



From Discovery Bay. The specimen is of medium size and in 

 the ordinary chitinous tube. 



Occurs in Britain, Finmark, Spitzbergen, and on the American 

 side from the Grulf of St. Lawrence to Grreenland. 



Fam. LuMBRiciDiE. 



Clitellio arenarius, 0. F. Mailer*. 



Specimens were found clinging to roots of Laminarice in 

 82° 30' N. lat. 



This species does not appear to have been rediscovered since 

 O. Fabricius described it. 



Nemertinea Anopla. 

 Fam. LiKEiDiE. 

 Two examples, apparently the Planar iafusca of Fabricius f, 

 come from Franklin- Pierce Bay, in 15 fathoms. Bottom-tem- 

 perature 29°"50. The appearance of the specimens and the struc- 

 ture of the proboscis (which is very well shown) make it probable 

 that the species indicated by Fabricius is very closely related to 

 Micrura fusca, Mcl.% The styliform process at the tail may have 

 been overlooked.
