S. I. Smith — Crustaeemis of the Atlantic Coast. 39 



Nova Scotia, 16 to 21 fathoms, on bottoms of fine sand, and of fine 

 sand and red algJB, 1877, 



Found in abundance in the stomachs of the cod (!) taken in Casco 

 Bay and the Bay of Fuudy. 



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, liowever. 



The largest specimens I have examined are from Casco Bay. One 

 of these, a male, lias the carapax 83""" long and 129-2""" broad.

Leidy (Journal Acad. Nat. Sci. Philadelphia, iii, p. 149 (17), 1855) 

 mentions '■'■ Plat year cinus 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 

 Mr. Faxon that there are specimens in the Museum of Comparative 

 Zoology, at Cambridge, from the Bermudas," and that " it rano-es 

 from Nova Scotia to the West Indies," but fails to give any explana- 

 tion of this last extension of its ransfe southward.
