192 PROCEEDINGS OP THE ACADEMY OP [1884. 



On this island may also be found shell implements of several 

 patterns, made from the shells of Busy con pyrum. 



The stone implements found there are similar to those figured 

 on Plate II, in the Memoir referred to, and the shell implements 

 are similar to those on Plate VII of the same. Near Dwight's 

 Landing, on the shore of Clearwater Harbor, is an Indian mound 

 composed chiefly of the shells of Busycon pyrum and Fasciolaria 

 tulipa; the former greatly predominating in numbers. Nearly 

 all of these shells have a hole in the side near the top, about 

 three-quarters of an inch in diameter, all neatly and uniformly 

 made. 



It is presumed that the animal was detached from the shell by 

 the Indians, by means of an instrument inserted through this 

 hole.
