the mound. It is at present an abundant spe- 

 cies in shallow water from Cape Cod to St.

cured several specimens of this left-handed 

 form. It is a post-pliocene species ranging 

 from Cape Hatteras to Cuba.

represented by several young examples taken 

 by Professor Hitchcock. It occurs from

7. Oliva literata Lam. But one specimen was 



found. It was near the middle of the mound. 

 Its present range is from Hatteras to Key

next to the Donax, the most common shell in 

 the mound ; especially in the upper half. At 

 present it is abundant along the beach oppo-

of this "boat-shell" were found. They were
