Gegenbaur has shown in his Wirbelthiere that in hind-feet of tailess Batrachian the gradation by which 2 of the bones in first row of 5 tarsal bones have disappeared or are represented by cartilage—

Two other bones have quite disappeared— on the other hand some small accessory bones are present, beside 2 which some have thought represent extra digits, but which view G. denies.—
