Abstract:

Osteological diagnosis of modern genera Bufo and Rana as well as species Bufo bufo, B. gargarizans, В. verrucosissimus, В. viridis, В. raddei, В. calamita, Rana temporaria, R. chensinensis, R. arvalis, R. asiatica, R. amurensis, R. ridibunda, R. lessonae and R. nigromaculata are given. The genera investigated are distinguished very easily, because practically all the skeletal elements, with the exception of distal elements of the limbs, have their specific generic features. Bufonids have 9-11 bones used for species identification. The most important of them are ilium, frontoparietale, maxillare, and parasphenoideum. Ranids have 6-7 such bones, the most important of which are ilium, frontoparietale, and scapula.
