remains. Many of the worms were already completely disintegrated^ 

 but the anterior ends of some were sufficiently intact to remove any 

 reasonable doubt of the correctness of this identification. The only 

 respect in which they differ from the published descriptions is in the 

 presence of as many as 4 stout setae in the first parapodium (somite 

 IV). A noteworthy characteristic of the species is the considerable 

 length of the cirriform appendage of the parapodia. 



Anteriorly the dorsum is a diluted chocolate brown, the surface of 

 the eye cups, the prostomium and a transverse band across each 

 segment being still darker. A brown spot at the base of each dorsal 

 cirrus appears to continue for the entire length of the body. The 

 large numbers in which these worms occur in the salmon stomachs and 

 the evidences that they were filled with sperm and ova indicates that 

 at sexual maturity they must swim in great shoals at the surface. 



Originally described by Kinberg from the China Sea, this species has 

 since been twice taken in the Atlantic Ocean, but until now has not 

 been reported from the Pacific.

Podarke -pugettensis Johnson, Proc. Bos. Soc. Nat. Hist., XXIX, 1901, pp. 

 397, 398. 

 This species was taken only in the region of the type locality and 

 probably does not extend much farther northward. 



Nanaimo Bay, Vancouver Island, B. C, taken from a starfish (Tuidia) 

 brought up on a fish line; Quarantine Rock, near Port Townsend, 

 Washington; Station 4218, Admiralty Inlet, near Port Townsend,

 The presence of this circumpolar species throughout a great extent 

 of both sides of the North Pacific is already well known. Typical 

 examples occur in the collections from the following stations : 4230, 

 vicinity of Naha Bay, Behm Canal, southeastern Alaska, 108-240 

 fathoms, rocky; 4236, vicinity of Yes Bay, Behm Canal, 147-205 

 fathoms, rocks and coarse sand; 4240, junction of Clarence Strait and 

 Behm Canal, 248-256 fathoms, coral.
