Polychaeta : 9B 
_ _ 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.

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 29f. (latitude 
70° 13’ N., longitude 140° 50’ W.) Water depth about 30 fathoms.

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. 
Locatiry.—Northwest Territories: Dolphin and Union strait: off Cockburn 
point. Station 48a. September 13, 1915. Depth, about 100 metres. Bottom,
