A LIST OF SHELLS FROM THE EAST COAST OF FLORIDA.

BY BRYANT WALKER.

The late Dr. Charles A. Davis, the well known peat-expert of the U. S. Bureau of Mines, in addition to his special acquirements in geology and botany, was a good all-round zoologist and had a lively and unaffected interest in the work that any of his friends might be carrying on in that department. It was his kindly habit in his travels about the country to preserve any specimens that he came across that seemed to him likely to be of interest to any of his zoological friends. It will be remembered that the conchologists owe to him the rediscovery of the long lost Planorbis multivolvis Case, (Naut., XXI, p. 16), and also the little Lymnæa davisi Walker, (Naut. XXII, p. 17), which bears his name.

In the spring of 1911 Dr. Davis’ professional duties took him to Florida and while there he collected quite a number of samples of “drift,” which in due time came into my possession. Several of the localities represented in the collection, such as Miami and St. Augustine, have already been reported upon by previous collectors and there seems to be no occasion to duplicate their work, but quite a number of the places visited by Dr. Davis have not been covered by any of the previous collectors in Florida and a record of the species found by him seems worthy of publication as a contribution to the distribution of the Mollusca along the east coast of the state.

I am indebted to Dr. George H. Clapp for the identification of the Gastrocoptas and Vertigos.

The list of localities and species represented in the collection is as follows:

Marshes near Chester Shoals.

Euglandina rosea Fér.

Polygyra cereolus carpenteriana Bld.

Zonitoides minuscula (Binn.).
