Although Bellamy does not use the simplified terminology which I am suggesting, his interpretation is substantially the same as I have given. The essential points are that in P. maculatus sex-linked characters are borne in a Y (male determining chromosome) whereas in P. variatus they are borne in an X (female determining chromosome). When the two systems are brought into competition, Y is dominant over X as in Drosophila, this being thus indicated as the more primitive system. It is not clear what is the result when the strong X of one system is combined with the strong Y of the other system; possibly it results in the production of an intersex.
