The British amphibians of the "past are represented by about 

 three dozen species, a number so small that considerable additions 

 would seem to be inevitable. None at all have been found below 

 the Carboniferous system, but that series of rocks has yielded 

 twenty species, while the Permian has yielded two, the Trias seven, 

 and the Rhaetics one, Metopias diagnosticus from Aust Cliff, which is 

 the last, as yet, of our extinct amphibians. The succeeding forma- 

 tions have yielded none until we get to the Forest Bed, where we 

 meet with the Toad, the Crested Newt, the Edible Frog, and the 

 Common Frog; but these are confined to this bed, and no amphi- 

 bian has up to the present been found in deposits of more recent 

 date, a state of affairs evidently due more to non-discovery than to 

 peculiar distribution.
