OP THE BiTKAOHIA. 



107 



Spelerpes occurs in Italy. The Asiatic Subregion is characterized 

 by the presence of two outposts of the Indian genus Bhacophorus ; 

 no Felohatidce have as yet been found within its boundaries ; and,' 

 the Discof/lossidce are represented by the European BombinaM 

 igneus only. The Gaudata belong mostly to the Amblystomatince, 

 the Salamandrince bein^ represented by only 4 species (against 19 

 in the European Subregion), one of which is widely distributed in 

 Europe. We must also notice the occurrence of Megalobairachus, 

 closely allied to the Forth-American Cryptohranchus. 



The following table wiE show the proportions of the known 

 genera and species in the two subregions. The Euro'pean Subregion 

 appears at present richer both as regards genera and species ; but we 

 may expect this fact to be reversed when the fauna of Central Asia 

 is better known.
