Labrador coast in 1864, says: this "beautiful species first occurred in abun- 

 dance in patches of sand on a stony bottom in 7 fathoms at the anchorage 

 in Domino Harbour. It was afterwards found commonly in 15 to 30 fathoms 

 at Square Island ; also at Thomas Bay, 1 5 fathoms, sand ; Long Island, 

 Sandwich Bay, 15 fathoms, sand."

 from the banks of Nova Scotia and Newfoundland. " It is very closely

" This fine starfish is by no means rare in New England, although not 

 yet noted by our naturalists. At Grand Manan it occurred on muddy 

 bottoms in 50 and 60 fathoms " (Stimpson). In his Handbook of Zoology, 

 published in 1870, Sir J. W. Dawson says that it has been found on the 

 " coast of Nova Scotia." It is one of the most characteristic starfishes of 

 the greatest depths of the Gulf of St. Lawrence. Living specimens of it 

 were dredged by the writer, in 1871, off Bear Head, Anticosti,in 120 fathoms; 

 in 1872 and 1873, at several localities to the south and south-east of Anti- 

 costi, in 108 to 220 fathoms ; and in 1873, one large specimen was dredged 

 at the entrance to Gaspe Bay, in 50 fathoms. Verrill says that it ranges in
