PROCEEDINGS OF THE ACADEMY OF 



[Nov., 



A LIST OF SHELLS COLLECTED IN WESTERN FLORIDA AND HORN 

 ISLAND, MISSISSIPPI. 



BY E. G. VANATTA. 



During February and March, 1902, Mr. Clarence B. Moore collected 

 the following species of shells while on an archaeological expedition in 

 western Florida. Most of the specimens were picked up on the 

 shore. The numbers after the species correspond to the numbers of 

 the localities, as follows: 



1. AlHgator Harbor, Franklin county, Florida. 



2. St. George's Sound, Franklin county, Florida. 



3. Indian Pass, Apalachicola Bay, Calhoun county, Florida. 



4. St. Joseph's Bay, Calhoun county, Florida. 



5. Crooked Island, off St. Andrew's Sound, Calhoun county, Florida. 



6. St. Andrew's Bay, Washington county, Florida. 



Those numbered 7 are a collection of shells from Horn Island, Mis- 

 sissippi, presented to the Academy some years ago. It is hoped that 

 this list, which well covers the western coast of non-peninsular Florida, 

 will be a useful appendix to Prof. W. H. Ball's Bulletin 37 of the U. S. 

 National ]\Iuseum. I wish to thank Prof. W. H. Dall, Mr. C. W. John- 

 son and Dr. H. A. Pilsbry for their assistance in identifying some of 

 the species of this collection.
