Vineyard Sound to Chelsea, MassacUiisetts. Sometimes abundant on 

 Chelsea Beach, after storms. Wood's Hole (H. E. Webster). Seleuka 

 gives "Grand Manan" (! from specimens in Mus. Corap. Zool.), but 

 after very careful search during several excursions to that island, I have 

 never been able to find it there, and believe this to be an error. Stimp- 

 son knew it only from Massachusetts Bay.

 Cod ; Chelsea Beach, Massachusetts. Sag Harbor, Long Island,
