MOLLUSKS OF WELLESLEY ISLAND AND VICINITY, ST. LAWRENCE 



SIVER. 



BY FRANK C. BAKER. 



Several years ago the writer spent two weeks at Thousand Island 

 Park, and a collection of the mollusks of the nearby region was made. 

 Local lists from this part of New York State are lacking, and the 

 following catalogue may be of interest for this reason. The locali- 

 ties where collections were made are as follows, all being in Jeffer- 

 son County, N. Y.: 



1. Goose Island, near Wellesley Island. 



2. South Bay, Wellesley Island. 



3. Blind Bay, New York shore. 



4. Watson's Point, Wellesley Island. 



5. Thousand Island Park, Wellesley Island. 



6. Lake Waterloo, Wellesley Island. 



The Thousand Islands lie in the head of the St. Lawrence at 

 the outlet of Lake Ontario. Wellesley Island is one of the large 

 islands. It is high and rocky, the rocks being granitic. It is well 

 wooded over a rolling surface, with here and there a pond or swamp.
