Off Cape Sable, N.S., in 88 fathoms ; and about twenty-six miles south of 

 Chebucto Head, in 101 fathoms; U. S. Fish Commission, 1877 (S. I. Smith, 

 1879; op. cit., p. 41). The species is widely distributed throughout the Gulf 

 of St. Lawrence, though it is rarely taken by the dredge. Fine large speci- 

 mens are brought up on fishermen's lines at Little Metis, and elsewhere. Sir 

 J. W. Dawson, in his Hand Book of Zoology (1 870), speaks of it as the "great 

 spider crab, which is our largest species, sometimes measuring eighteen 

 inches in extreme breadth." Packard says that " a number were taken 

 from the stomachs of cod from the bank " off Caribou Island, in 1860 ; also, 

 that the species is not uncommon in the Strait of Belle Isle, in 10 to 50 

 fathoms;" and at Chateau Bay, Labrador, in 30 to 50 fathoms."
