Xew Jersey to Labrador. Anticosti Island (A. E. V.) ; not uncommon 

 in Massachusetts Bay, Casco Bay, and Bay of Fuudy, 10 to 100 fath- 

 oms. Less frequent south of Cape Cod ; off Block Island, in 29 fathoms. 

 (A.. S. Packard); Xewport, Rhode Island (Totten); Greenport, Long 

 Island (S. Smith). Chateau Bay, Labrador (Packard). 



This species, when young, is liable to be confounded with Thracid 

 myopsis Beck = T. Couthouyi Stimpson (see Plate XXVII, fig. 190), but 

 they are easily distinguished by the structure of the hinge. The latter 

 occurs in Massachusetts Bay, Bay of Fuudy, etc., northward to Green- 

 land, but has not been recorded from south of Cape Cod.
