an d Protop elobates in that of Bohemia. The extinct family of Table-case, 
Palaeobatrachidae has teeth in the upper jaw and no ri bs ; it was No ’ 24 ’ 
widely distributed over the continent of Europe in Miocene Batrachia; 
times, and was represented by a single genus Palceobatrachus , Toads’, 
and more than a dozen species from various localities. 
The true toads, Bufonidjs, have no teeth or dorsal ribs. 
Existing species of the genus JBufo occur in the European and 
Indian Pliocene deposits. P. 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- 
phate-deposits ” of France. 
The huge Geratophrys cornutus , or Horned Frog of Brazil, 
occurs in the Cave deposits of that country ; and the genus 
Latonia in the Miocene of Switzerland. 
The Ranidoe, or true 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 or 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 Wall-case, 
Lizard, or is still more elongated like that of an Eel ; in some No * 11 * 
there are four limbs present, in others only the anterior pair are Table-case,

retained in the adult animal. Ilylceobatraclius is found in the tiers. 
Wealden of Belgium and may be an ancestral form allied to the 
Vroteidoc but distinguished by the presence of a maxilla and five 
digits to the feet. (The only specimen known is in the Brussels 
Museum.) 
In the family of Amphiumidre is placed Megalobatrachus
