THE LAND-SHELLS OF IRONBOUND ISLAND, MAINE. 



BY DWIGHT BLANEY. 



The following land-shells have been collected on Ironbound 

 Island, Frenchman's Bay. This is one of the many rocky islands 

 on the coast of Maine — with h.igh cliffs toward the sea, and sloping 

 to the water on the bay side. 



Heavily covered with spruce mixed with a few birches, and with 

 comparatively little cleared land, it does not seem a very likely place 

 for collecting land-shells. Under the guidance of our friend Prof. 

 Edward S. Morse, we have ransacked all favorable situations, and 

 feel well rewarded with the following nineteen species. 



The numerals refer to Pilsbry and Johnson's Land-shells of 

 America. 



No. 141. Polygyra monodon (Rack.), common. 



No. 200. Pupa muscorum (L.), common.
