Common and of general distribution in Vineyard 
Sound; taken at a few inshore stations on the 
lower half of the eastern side of Buzzards Bay; 
dredged in from 1 to 13 fathoms, on bottoms of 
sand, gravel, and stones, rarely in mud. — Sur- 
vey. Recorded also from various points dur- 
ing the shore collecting. This species dwells 
in tubes, though frequently leaving these; it 
is found among weeds and hydroids, on piles 
and elsewhere, as well as in deeper waters.
