EDIBLE MOLLUSKS OF RHODE ISLAND. 



BY HORACE F. CARPENTER, PROVIDENCE, R. I. 



I have read with much interest the article in the January Nauti- 

 lus by Prof. Keep and its supplement by Henry W. Winkley in 

 the February number and am tempted to add a short article on the 

 edible mollusca of Rhode Island. I think in point of numbers of 

 species, as well as individuals, Rhode Island will excel any state in 

 the Union. As we have seen California has but five species and 

 Maine only four regulars and two occasional, while Rhode Island 

 can show eight every day and five irregular as below.
