Common from Massachusetts Bay to Labrador and Greenland, and 

 also on the northern coast of Europe, and the northwest coast of 

 Korth America. Extremely abundant for several feet above low- 

 water mark of spring tides at Eastport, Me., and Grand Menan, on 

 rocky bottoms ; and also in ten to twenty fathoms. Small specimens 

 were collected by Dr. A. S. Packard, Jr., in fifty fathoms, Straits of 

 Belle Isle, Labrador. Drift Clay, Portland, Me. A. Agassiz mentioned 

 specimens, probably of this species, from an outlying bank situated 

 off the coast of New Jersey, in about thirty fathoms, Capt. Gedney.

Massachusetts Bay to Labrador and Greenland ; on European 

 coast south to Denmark and Great Britain. Exceedingly abundant

 fathoms lower, covering rocky bottoms. I have also dredged it abun-

The specimens are mostly dark brown or purplish, yellowish below. 

 One specimen occurred at Grand Menan of a uniform, light yellow. 

 Commonly called ''Sea Cucumber" on this coast.
