Polychaeta 9 B 



This northern form is exceedingly common in the fjords of Greenland and 

 is known also from Davis strait. From this region it ranges along the American 

 coast to the gulf of St. Lawrence, to the northern European shores and south- 

 ward to Ireland. It has been dredged in the Atlantic at a depth of 580-630 

 fathoms (Porcupine). The collections of the Canadian Arctic Expedition 

 extends the range westward to Bernard harbour and other points on Dolphin 

 and Union strait. 



LOCALITIES. Northwest Territories: Bernard harbour. Station 37 1- 

 October 19, 1914. Several specimens taken at a depth of about one fathom 

 on a bottom of sandy mud among algae. 



Northwest Territories: Dolphin and Union strait: west of Cockburn point. 

 Station 43c. September 14, 1915. Several specimens from a depth of 20-30

The specimen has the characteristic cross-markings of dark pigment with 

 the broader solid band across somite VIII. It is a common form on the western 

 North American coast from San Diego northward to Alaska but is less common 

 in the more southern part of this range. 



APHRODITIDAE. 

 Aphrodita sp. 



Two fragments of an Aphrodita taken from the stomach of a Phoca hispida 

 Schreber are not in condition to permit specific identification. The Phoca was 

 taken April 4, 1914, off the coast of Yukon Territory at Station 29/. (latitude 

 70 13' N., longitude 140 50' W.) Water depth about 30 fathoms.

 circumpolar distribution, having been previously recorded from Spitzbergen, 

 Nova Zembla, Kara sea, Siberia, Alaska, Prince of Wales island, Davis strait, 

 Greenland, Iceland, Faroe islands, and southward in the Atlantic to the United 

 States and France.
