the two species (Table 2). At four loci iCKB*. FH*. LDH- 

 B*. and ICDH-S*) C. fulva and P. furcifer had different 

 alleles. Forty C. fulva, 28 P. furcifer, one C. cruentata, and 

 ten putative hybrids were subsequently screened at the 

 four diagnostic allozyme loci (Table 5). Eight often puta- 



tive hybrids were heterozygous at all four diagnostic loci. 

 One putative hybrid was heterozygous at all loci except 

 the LDHB* locus, for which it displayed two alleles 

 characteristic of P. furcifer, and another individual was 

 heterozygous at all diagnostic loci, except the FH* locus
