Its fre- quency in tliis area ranged up to in the populations where it was detected. It was, however, conspicuously absent in samples of intermediate morphotype from the west side of The Crossing (Locs. 253, 255) and Sandy Point (Loc. 251) and in the "pure" C. abacoeme from Hole-in-the-Wall (Loc. 250). The isolated occurrence of 6-Pgdh-l'' on Little Abaco is tentatively interpreted as being due to mutation and drift. The oc- currence of this allele at higher frequencies on Grand Bahama and in the transition zone between the morphotypes on Great Abaco must be due to other forces. Glutamic oxalacetic transaminase. In C. hemlalli, two equally common alleles were found in 12 populations from northern and central Great Abaco (Gould et al., 1974; Woodruff, 1975). As seen in Table 13 and Fig. 14, Got-l'' occurs at a slightly higher frequency than Got-P' throughout the range of this taxon. Got-l'' reaches its greatest frequencies () in western and in- terior samples from Grand Bahama. Seven samples of the ribby morphotype, C. ah- acoetise, were also examined and found to have Got-l-' frequencies of Fre- quencies of were found to char- acterize samples from the area of interac- tion between these taxa. A third allele, Got-1*^ is now reported from southern Great Abaco where it occurs at low frequency (). It has been detected in "pure" C. abacoense (Loc. 250) and 4 samples of intermediate morphotype from Sandy Point (Loc. 251), The Crossing (Loc. 255) and near Rocky Point (Locs. 308, 311). This rare allele has yet to be found in "pure" C. bendaUi from A
