The specimens referred to this species are in a bad state of preservation, 

 but they seem to conform to the description in so far as the characters can be 

 made out. The species was found originally in Scow Bay, in the Puget Sound 

 region, where it was abundant. "This worm seemed to occur in a layer along 

 the somewhat muddy bottom, for bushels of this jelly-Hke mass exclusively were 

 brought up from a region half an acre in extent " (Harrington and Griffin, Trans. 

 N. Y. acad. sci., 1897, 29, p. 162). Some of the Scow Bay specimens came from 

 a depth of not more than six fathoms, but data on others were lacking. The 

 Alaskan specimens here recorded came from a greater depth. Their long black- 

 tipped ventral hooks and the long pedicillate papillae are conspicuous features. 



Locality. Between Unalaska and Kadiak: Sta. 3337 (lat. 53° 55' 30" 

 N., long. 163° 26' W.). Depth 280 fms. Bottom of green mud and rock. Bot- 

 tom temp. 39.3° F. Two specimens dredged 27 August, 1890. They are at 

 present free from any enclosing jelly-hke mass.
