Text Appearing Before Image:
116 THE BIOLOGY OF THE AMPHIBIA changes would not account for the marked sexual difference in color pattern seen in some frogs and salamanders. Most Amphibia, unlike lizards and birds, show little or no sexual difference in color.

Text Appearing After Image:
Fig. 40.—Secondary sexual characters in Old World frogs. A. Left manus of Dimorphognathus africanus as seen from below, showing the elongated third finger of the male. B. Head of the male of the same species with the pseudo- teeth of the lower jaw characterizing this sex. C. Head of the male Petropedetes newtonii showing the columella process, the spike-like metacarpal I and distinc- tive chin spines. D. Head of Rana pileata with the frontal swelling peculiar to the male. where marked sexual differences in color appear these have an important role in sex recognition or courtship. The types of courtship found in Amphibia are usually not such as would foster a sexual divergence in color. Phylogeny of Secondary Sex Characters.—The phylogeny of other secondary sexual characters is instructive when considered
