 Gloucester fishermen often brought it in from the various fishing banks off" 

 Nova Scotia and Newfoundland, in 100 to 300 fathoms, 1878-80. Off Grand 

 Manan, in 40 to 50 fathoms, on shells covering Eupagurus, and in 109 

 fathoms, on rocks (Verrill). By the Challenger Expedition it was dredged 

 in 1873, at Station 49, off Nova Scotia, in 85 fathoms. In the Gulf of St. 

 Lawrence, one specimen of the incrusting variety was dredged by the writer 

 off Charleton Point, Anticosti, on a small stone, in 1871 ; and one, also on

" A few specimens taken by the Gloucester halibut fishermen, in deep 

 water, off Nova Scotia, and by ourselves in 1880. The coenenchyma of this 

 species at first invests small univalve shells, occupied by Parapaguriis 

 pilosimanus, but finally grows far larger than the shell, and eventually 

 absorbs it " (Verrill).
