Distribution. Cosmopolitan, except in the southern parts of South 

 America, in Australia and New Zealand. Some 140 species are 

 known, 41 of which occur within the limits of this fauna. All 

 Indian species are probably aquatic during the breeding-season ; 

 othernise their habits vary greatly according to the species, which 

 may be aquatic, terrestrial, burrowing, or to a certain extent 

 arboreal. Burrowing habits are indicated by the great develop- 

 ment of the inner metatarsal tubercle, which is sharp-edged, and 

 acts as a shovel, as in R. breviceps ; this character is accompanied 

 by an abbreviation of the hind limbs, which gives the frog a toad- 

 like appearance. Arboreal habits are usually to be recognized by 

 the distal enlargement of the digits, althougli some strictly aquatic 

 forms, such as 11. huldii, have the toes ending in small, but very 

 distinct disks.
