and Protopelohates in that of Bohemia. The extinct family of 

 iPalceobatrachidce has teeth in the upper jaw and. no ribs ; it was 

 widely distributed over the continent of Europe in Miocene 

 times, and was represented by a single genus Palceobatrachtis, 

 and more than a dozen species from various localities. 



The true toads, Bufonidce, have no teeth or dorsal ribs. 

 Existing species of the genus Bitfo occur in the European and 

 Indian Pliocene deposits. B, Gesneri from the Upper Miocene 

 of Switzerland agrees closely with the living B. viridis. Dr. 

 Filhol records the type-genus from the Upper Eocene Phos- 

 phorites of France. 



The huge Geratophrys cornnhis, or Horned Frog of Bi-azil, 

 occurs in the Cave deposits of that countiy ; and the genus 

 Latonia in the Miocene of Switzerland. 



The Banidoe, or tme frogs, have teeth in the upper jaw and 

 the extremities of the sacral ribs are not expanded. Species of 

 Bana are found in the Norfolk Forest Bed, in the Pleistocene 

 of Sardinia, the Miocene of Sansan ; two are from the Brown 

 Coal of Rott, near Bonn, others from the Upper Eocene Phos- 

 phorites of Caylux, France ; several forms occur in the Middle 

 Tertiary of Italy, &c.

Order II.— CAUDATA. (Salamanders, &c.) 



In this order the body of the animal resembles that of a 

 Lizard, or is still more elongated like that of an Eel ; in some 

 there are four limbs present, in others only the anterior pair are

developed. The external gills of the larva are occasionally Salaman- 

 retained in the adult animal. HylcBobatraclius is found in the ders. 

 Wealden of Belgium and may be an ancestral form allied to the 

 Proteidoe but distinguished by the pi-esence of a maxilla and of 

 five digits to the feet. (The only specimen known is in the 

 Brussels Museum.) 



In the family of Amphiumidce is placed Megalolatrachus
