In addition to .the preceding catalogues of the shells of Mass, 

 full and apparently quite accurate,! have received from Col. Joseph G. 

 Totten of the United States Army, resident in Newport R. Island the 

 following list both of marine and land shells observed " on and near the 

 coast of New England." Although this extends beyond the limits as- 

 signed me by the government, yet as so little is known of this class 

 of animals, and so few gentlemen have devoted their attention to it, it 

 has seemed to me probable that it would comport with the views of 

 government to annex this catalogue to those already given ; contain- 

 ing as it does several species and genera that have not been mention-
