Stimpson says that /. irrorata is " found on marine plants about low-water 

 mark" at Grand Manan. "It rarely occurs here, although so common on 

 the south-western portions of the coast of Maine." Harger says that it is 

 "found along the whole coast of New England and extends southward 

 along the coast of New Jersey, at least as far as Great Egg Harbour, 

 and northward to Nova Scotia and the Gulf of St. Lawrence, where it has 

 been collected by Mr. J. F. Whiteaves. From Cape Cod southward it is 

 abundant, but towards the north it is, mostly, leplaced by I. j^hosphorea. 

 It is commonly found among sea-weed along the rocky shores of bays and 

 sounds or among the rocks, where its variety of colours affords it protection. 

 It is also found far from land, attached to floating sea-weed, and was thus 

 taken by Professor S. I. Smith and the writer on Georges Banks, September 

 U and 15, 1872, at about 41° N. lat., 65° W. long."
