. Breviora. 1969 NEW ENGLAND CANIS second they were more evenly distributed between dog and wolf, with the majority of the specimens actually intermediate. These relationships are shown in Figure 1. Fig. 1. Linear discriminant values of known dog-coyote hybrids (H). The latrans-familiaris discriminant function is used as the abscissa and the latrans- lupus discriminant function is used as ordinate (from Lawrence and Bossert, 1967). The contours are extreme ranges of individuals of C. latrans (C), C. lupus (W), and C. familiaris (D) used in computing the discriminant func- tions. Fo skulls were also studied. These were the result of subsequent crossing in various combinations, using the collie and labrador hybrids as well as a male springer. Discriminant functions were evaluated for these as for the Fi hybrids. All fourteen proved to be intermediate between latrans and familiaris but showed a larger proportion falling within three standard deviations of one or the other. Interestingly, in the latrans-lupus discrimination they differ from the Fi series in being uniformly latrans- like, though in the jamiliaris-lupus discrimination they coincide exactly with the Fi series. The Fo relationships are shown in Figure 2. The evidence then is that, while the discriminant functions of both groups of hybrids are intermediate between those of the two parent stocks, further discrimination to see whether the trend towards dogness in particular individuals is expressed as wolfness.
