Polychaeta 11 B 



longitudinal rows of papillae as in members of the ciliata group, with a similar 

 long dorsal papilla. 



LOCALITY. Hudson bay: east side, Richmond gulf. June, 1899. Depth, 

 15 to 25 fathoms. Two specimens. A. P. Low, collector. 



This species resembles ciliata in the general form of the parapodia and 

 shortness of its setae; but it is conspicuously different in the form and relations 

 of the prostomium. In ciliata this is more quadrate, with the anterior region 

 projecting farther forward obviously beyond the edge of the first segment with 

 anterolateral corners subrectangular, and the posterior tentacles borne decidedly 

 farther caudad on the nearly longitudinal free lateral edges instead of being at 

 essentially the same level with the anterior pair as they are in the species above 

 described.

This is a well-known northern form of apparently circumpolar distribution 

 common on the shores of Greenland, Nova Zembla and Spitzbergen and less 

 common on the shores of Finmark, Norway and Sweden and southward to 

 Ireland and the gulf of St. Lawrence. It has also been recorded from Siberia, 

 Bering strait, and Bering sea. 



LOCALITIES. Northwest Territories: Bernard harbour, outer part. Station 

 4 If. August 1, 1915. One specimen taken at a depth of 2-3 fathoms on a 

 bottom of sandy mud with stones and algae.

 developed specimen, taken in 7-5 fathoms of water. Arctic Expedition. 



Eteone longa (Fabricius).

Three specimens of Eteone agree well with examples of E. longa from Green- 

 land, the type locality, in the Museum of Comparative Zoology at Cambridge, 

 Mass. The specimens are dark and the largest has a length of 52 mm. The 

 species has not been previously recorded excepting from the shores of Greenland, 

 where it seems to be common. The closely related E. arctica Malmgren, 

 which may possibly have been confused to some extent with the present species, 

 has an apparently circumpolar distribution, having been listed from Davis 

 strait, Spitzbergen, Finmark, Great Britain, Siberia, and Bering strait. 



LOCALITY. Northwest Territories: Bernard harbour, outer part. Station 

 41. July 20, 1915. Depth, 3-5 fathoms. Sandy mud with algae. 



Paranaitis sp. Larva. 



A number of larvae of the species of this genus were secured in plankton 

 along with spionid larvae and numerous Crustacea. They are in stages possessing 

 from 13 to 20 setigerous segments. The fused first two segments in all form 

 dorsally a conspicuous collar-like swelling. It is quite possible that these larvae 

 pertain to P. wahlbergi (Malmgren) which has been recorded from Bering sea 

 by Wire*n l and is a common and widespread form.
