Between species of Australia and South and ll^orth America there 

 exist close relations. Those of smallest size occur in North America, 

 where several spend but little of their time in trees, but like the African 

 Hyperolii prefer low lands and swamps. Larger species of similar habit 

 occur in Australia. 



The distribution of the North American species is as follows: 



Atistroriparian District, Eastern District. Sonoran District. Pacific District. 



H. versicolor. 

 H. gratiosa. 

 H. femoralis. 

 H. squirella. 

 H. carolinensis. 



H. versicolor. 



H. pickeringii. 



H. arenicolor. 



H. resilla. 



H. regilla. 



H. andersonii. 



Of the eastern species, M. versicolor , H. pickeringii., and R. andersonii., 

 are the only ones which extend their range north of southern North 

 Carolina. H. andersonii has been found so far, east of the Appalachian 

 range, from New Jersey to Georgia, R. versicolor and R. picJceringii
