Discussion: The shape of the ilium corresponds to that in contemporary Bufo bufo and B. viridis. The only difference is that in both latter forms the longitudinal depression on the medial surface of the ala is developed in much lesser degree (due to lesser extent of the edge). It should also be noted that the orifice of the mentioned canal on the medial surface of the bone displays certain variation in contemporary forms (the orifice may be doubled, and the differences in this respect may be found also between the left and right ilium of a single individual). The same seems to hold for fossil material. Size differences may be ascribed either to interspecific variation or to differences between both sexes (the latter may reach quite a high degree in some contemporary representatives of the genus Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Asiatic Herpetological Research Society; Chung-kuo liang chi pa hsing tung wu hs©eh hui.
