Twenty individuals were sequenced from each sampling site except for Key Biscayne. where only four specimens were obtained. revealed 10 variable sites and 12 haplotypes (Table 1). Of the 11 nucleotide substitutions (all synonymous) detected, 8 were third codon transitions, 2 were first codon transitions, and 1 was a third codon transversion. Genetic divergence levels among the haplotypes was very low, with a maximum of four substitutions () among pairwise comparisons. Floridian and Bermudan haplotypes exhibited one diagnos- tic third codon transition—, no haplotype was shared among these two regional groupings. Table 2 shows the distribution pattern of the 12 haplotypes among the seven sampling sites. There was a striking discrepancy in the relative levels of haplotypic diversity and frequency in the Bermudan and Floridian samples. A total of 10 mt geno- types were contained in the combined oceanic island sam- ples, none of which exceeded a frequency of With the exception of a single individual from the Palm Beach pop- ulation, the Floridian specimens were monomorphic for hapl
