OF THK BATRACHIA.

Spderpes occurs in Italy. The Asiatic Subregion is characterized 

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

 no Pelobatidce have as yet been found within its boundaries ; and 

 the Discoglossidce are represented by the European Bombinator 

 igneus only. The Caudata belong mostly to the Amblysto matinee, 

 the Salamandrince being 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 Megalobatrachus, 

 closely allied to the North-American Cryptobranclms. 



The following table will show tho proportions of the known 

 genera and species in the two subregions. The European 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.
