This pretty little species, which is also called 
abroad the “ butter fish,” from the slime with which 
it is covered, is found at low tide upon the beaches, 
beneath stones and sea-weed; it is exceedingly dif- 
ficult to retain in the hand after it is captured, on 
account of its slipperiness and agility. 1t is com- 
mon at Nahant, Holmes Hole, and probably along 
our entire sea-coast. I have found it in the stom- 
ach of the “ Anarrhicas lupus,” and “ Cottus Vir- 
so.
