APPENDIX 



A CHECKLIST OF MOLLUSKS FOUND IN HILLS- 

 BOROUGH BAY, FLORIDA, AUGUST AND SEPTEM- 

 BER 1963 



We collected and identified 64 species of mollusks 

 representing 43 families. Determinations were 

 based on standard taxonomic works (Abbott, 

 1954; Perry and Schwengel, 1955; Warmke and 

 Abbott, 1962; Keen, 1963; Abbott, 1968) and by 

 comparison with specimens in the U.S. National 

 Mnseuni ( + ) . An asterisk ( * ) indicates that the 

 species was collected alive.
