While Stimpson, in his 1851 Hst, gives "whole New England 

 coast," as the range for this species, we have only the following 

 authentic records :

 (Fuller in P. S. N. H.) ; Old Orchard and Scar- 

 boro (Wentworth).

 This species seems to be rather scarce on the Maine coast. 

 We have only the following records and these mostly of dead 

 specimens :

 Casco Bay (Chickering and Kingsley) ; Ash Point, 

 Knox county (Lermond) ; Frenchman's Bay

 Of the edible qualities of this clam, Dr. Mighels, in his 1843 

 list, remarks as follows: "It is used by a few as an article of 

 food, but it is tough and indigestible and I have known some 

 to be seriously injured by eating it."
