Eunice oerstedi, Stimpson, Marine Invert. Grand Manan, 1853, pp. 34, 35. 
Habitat. — A. single specimen of good size was dredged at Station 45 (off the coast of 
North America, near New York), May 3, 1873 ; lat. 38° 34' N., long. 72° 10' W. ; depth, 
1240 fathoms; bottom temperature 37°‘2 C,, surface temperature 49°’5 ; sea-bottom, 
blue mud. 
A smaller example occurred at Station 49 (a little farther north, off the same coast), 
May 20, 1873 ; lat. 43° 3' N., long. 63° 39' W. ; depth, 85 fathoms ; bottom temperature

35°, surface temperature 40° '5 ; sea-bottom, gravel and stones. The other members of 
the fauna bore a close resemblance to those from the Gulf of St. Lawrence, Canada. 
Several specimens were dredged at Station 144a (off Marion Island), December 26, 
1873 ; lat. 46° 48' S., long. 37° 49' 30" E.; surface temperature, 41°; depth, 69 fathoms ; 
sea-bottom, volcanic sand. 
The latter examples are about 90 mm. in length and 5 mm. in diameter. 
The head (PI. XXXVIII. fig. 1) (at present confining the remarks to those from 
Marion Island) very much resembles that of Eunice norvegica, Linn., from Beigen, 
Norway, the chief difference being that the tentacle and other cephalic processes are pro- 
portionally longer in the Norwegian forms. In both the most distinctly segmented 
process is the outer cirrus, and in each the tentacular cirrus extends forward beyond 
the anterior border of the buccal segment.
