Nova Scotia, 16 to 21 fathoms, on bottoms of fine sand, and of fine 
sand and red algie, 1877. 
Found in abundance in the stomachs of the cod (!) taken in Casco 
Bay and the Bay of F undy. 
When found living between tides it is usually concealed among 
rocks or buried beneath the sand. It is usually much more abundant 
at or just below low-water mark than between tides, however. 
The largest specimens I have examined are from Casco Bay. One 
of these, a male, has the carapax 83 mm long and 129 , 2 mm broad.

Leidy (Journal Acad. Nat. Sci. Philadelphia, iii, p. 149 (17), 1855) 
mentions “ Platycarcinus irroratus M. Edw.” and “ P. Sayi DeKay” 
from Point Judith, Rhode Island, and Great Egg Harbor, New Jer- 
sey, intending, doubtless, to indicate both our species of Cancer , 
although the names with the authorities as given are in reality 
synonymous and apply to C. irroratus only. 
Kingsley (loc. cit.) reports a young specimen of this species from 
Fort Macon, North Carolina. He also says: “I am informed by 
M r. Faxon that there are specimens in the Museum of Comparative 
Zoology, at Cambridge, from the Bermudas,” and that “it ranges 
from Nova Scotia to the West Indies,” but fails to give any explana- 
tion of this last extension of its range southward.
