 below the tentacles. 



The original specimen was taken by the U. S. Fish Commission, in 458 

 fathoms, off Martha's Vineyard, 1881.

This large species is easily distinguished by its smooth, lubricous, stout, dull 

 red body, and by the very large, non-retractile tentacles. It often expands 

 150 to 255 mm. (6 to 10 inches) across the tentacles. The tentacles are often 

 50 to 75 mm. (2 to 3 inches) in length, and 10 to 15 mm. in diameter. The 

 body is ordinarily 75 to 100 mm. (3 to 4 inches) in diameter and height. 



When detached, which often happens, the tentacles retain their plumpness 

 and fusiform shape, and are capable of contracting and expanding, so as to 

 change their form, for some time, so that they resemble, and are sometimes 

 mistaken for, entire living worms or holothurians. 



The color is usually some shade of red, varying from pale flesh-color and 

 pink to dark red; the body, in the paler examples, is often more or less ttuged 

 with salmon. The disk and tentacles generally correspond in color with the 

 body, but are deeper in tint. When the body is flesh-color or light red, the 

 tentacles and disk may be rose-red or dark red, while those specimens that have 

 a dark red body may have the tentacles reddish brown or orange-brown. 



Fine large specimens were dredged by the Blake, at Stations 309 and 310, 

 in 304 and 260 fathoms, off Southern New England. 



Detached tentacles Avere taken off George's Bank, at Station 303, in 306 

 fathoms, N. Lat. 41° 34' 30", W. Long. 65° 54' 30". One large and character- 

 istic specimen was dredged at Station 326, off Cape Fear, N. C, in 464 fathoms. 



The following specimens were dreclged by the Blake, in 1880. 



It has been dredged at a large number of localities by the U. S. Fish Com- 

 mission, since 1872, in the deeper parts of the Bay of Fundy ; off Nova Scotia, 

 in 50 to 100 fathoms; Gulf of Maine, in 50 to 150 fathoms; off Casco Bay, m 

 40 to 90 fathoms; Massachusetts Bay, in 40 to 52 fathoms; off Cape Cod, in 

 37 to 90 fathoms. Off Martha's Vineyard, on the Gulf Stream Slope, it has
